Morbidity, comorbidity, and their association with disability among community-dwelling oldest-old in Israel.

BACKGROUND: The impact of chronic conditions on the development of disability has not yet been comprehensively studied among the elderly population living in Israel. This study evaluates the prevalence of disability and morbidity among the community-dwelling oldest-old population and examines the association between medical conditions, comorbidity, and disability in basic and instrumental activities of daily living (ADLs, IADLs). METHOD: The data are based on a national random stratified sample of 1,820 Israeli Jewish individuals 75-94 years old, of whom 1,487 lived in the community. RESULTS: Nineteen percent of the population was disabled in ADLs and 36% in IADLs. Disability rose with age and was higher for women and among individuals of Middle Eastern and North African origin. Stepwise logistic regression indicates that the variables associated with disability in ADLs and IADLs were older age, Middle Eastern or North African origin, living with others, and the following conditions: stroke, hip fracture, diabetes, osteoporosis, anemia, and heart attack. In addition, lower education and suffering from urinary or kidney diseases, respiratory disease, and/or Parkinson's disease were related to disability in ADLs; being a woman and suffering from heart diseases other than heart attack were related to disability in IADLs. Comorbidity was related to increased disability only for individuals with three or more conditions. CONCLUSIONS: The identification of medical conditions and sociodemographic variables related to limitations in functioning may serve as a basis for health promotion and disease prevention in elders by attempting to reduce the incidence and disabling consequences of known disabling conditions.

Disease, disability, and age in cognitively intact seniors: results from the Canadian Study of Health and Aging.

BACKGROUND: Many diseases have been identified as risk factors for disability in the elderly. This report contrasts disability in the old-old (85 years of age or older, 85+) with younger seniors (65-84 years of age) and examines whether diseases have an equivalent impact on the two groups. METHODS: Subjects were 603 cognitively intact community residents 65 years of age and older from 10 Canadian provinces. The purpose of the analysis was to try to isolate the effects of age and nondementing disease on function. Frequency of disease and functional disabilities was calculated. Logistic regression was used to determine significant explanatory variables for moderate, severe, or total disability and for specific disabilities. RESULTS: Nearly twice as many of the cognitively intact 85+ had functional disabilities compared to those 65-84 years of age. In the 85+, increasing age was the only significant explanatory variable for moderate, severe, or total disability and for problems with walking, showering, shopping, getting to places out of walking distance, and preparing meals. Diseases were also significant explanatory variables for functional disabilities, particularly in the 65-84 age range. An increase in the proportion with functional disability was found with increasing age even in those without the relevant disease risk factors. CONCLUSIONS: Disease prevention would only be partially effective in avoiding disability in the very old because disability occurred even in those without explanatory disease.

Lower extremity function and subsequent disability: consistency across studies, predictive models, and value of gait speed alone compared with the short physical performance battery.

BACKGROUND: Although it has been demonstrated that physical performance measures predict incident disability in previously nondisabled older persons, the available data have not been fully developed to create usable methods for determining risk profiles in community-dwelling populations. Using several populations and different follow-up periods, this study replicates previous findings by using the Established Populations for the Epidemiologic Study of the Elderly (EPESE) performance battery and provides equations for the prediction of disability risk according to age, sex, and level of performance. METHODS: Tests of balance, time to walk 8 ft, and time to rise from a chair 5 times were administered to 4,588 initially nondisabled persons in the four sites of the EPESE and to 1,946 initially nondisabled persons in the Hispanic EPESE. Follow-up assessment for activity of daily living (ADL) and mobility-related disability occurred from 1 to 6 years later. RESULTS: In the EPESE, compared with those with the best performance (EPESE summary performance score of 10-12), the relative risks of mobility-related disability for those with scores of 4-6 ranged from 2.9 to 4.9 and the relative risk of disability for those with scores of 7-9 ranged from 1.5 to 2.1, with similar consistent results for ADL disability. The observed rates of incident disability according to performance level in the Hispanic EPESE agreed closely with rates predicted from models developed from the EPESE sites. Receiver operating characteristic curves showed that gait speed alone performed almost as well as the full battery in predicting incident disability. CONCLUSIONS: Performance tests of lower extremity function accurately predict disability across diverse populations. Equations derived from models using both the summary score and the gait speed alone allow for the estimation of risk of disability in community-dwelling populations and provide valuable information for estimating sample size for clinical trials of disability prevention.

Inner city, middle-aged African Americans have excess frank and subclinical disability.

BACKGROUND: Healthy People 2010 seeks to decrease or eliminate the health disparities experienced by disadvantaged minority groups. METHODS: African American Health (AAH) is a population-based panel study of community-dwelling African Americans born between 1936 and 1950 from two strata. The first encompasses a poor, inner city area, and the second involves a suburban population with higher socioeconomic status. The authors recruited 998 participants (76% recruitment). Frank disability was assessed for 25 tasks and defined as inability or difficulty performing that task. Subclinical disability was assessed for 12 tasks and defined as no difficulty but a change in either manner or frequency of task performance. Frank disability prevalences were compared with national data for community-dwelling non-Hispanic white persons (NHW) and African American persons in the same age range. RESULTS: Compared with the suburban sample, the inner city group had a higher prevalence of frank disability for all 25 tasks (p<.05 for 16) and subclinical disability for 11 of the 12 tasks (p<.05 for 5). Both strata had more frank disability compared with the national NHW population. The inner city area had higher frank disability proportions than did the national African American sample, whereas the suburban group had similar disability levels. CONCLUSIONS: The AAH inner city group experiences more frank disability than other populations of African Americans and NHWs. The increased prevalence of subclinical disability in the inner city group compared with the suburban group suggests that the disparity in frank disability will continue. These findings indicate that African Americans living in poor inner city areas in particular need intensive and targeted clinical and public health efforts.

Disability as a function of social networks and support in elderly African Americans and Whites: the Duke EPESE 1986--1992.

OBJECTIVES: We examined the association of structural and functional aspects of social relationships with change in disability, and the degree to which race modifies these associations. METHODS: Data are from a population-based sample of 4,136 African Americans and Whites aged > or = 65 living in North CAROLINA: Disability data were collected during seven consecutive yearly interviews and summarized in two outcome measures. Measures of social relationships included five measures representing network size, extent of social interaction, and specific type of relationships, as well as instrumental and emotional support. Weighted proportional odds models were fitted to model disability as a function of baseline social network and support variables, and the interaction of each variable with follow-up time. RESULTS: Network size and social interaction showed significant negative associations with disability risks, which did not vary by race, or as a function of time. Social interaction with friends was associated with a reduced risk for disability, but social interaction with children or relatives was not related to disability. Instrumental support was associated with a significantly increased disability risk, with a greater adverse effect among Whites than African AMERICANS: Emotional support was not associated with disability, but a protective effect for ADL disability was found after controlling for its intercorrelation with instrumental support. DISCUSSION: The findings provide further evidence for the role of social relationships in the disablement process, although not all types of social relationships may be equally beneficial. Furthermore, these associations may be more complex than simple causal effects. There were few racial differences in the association of social relationships with disability, with the possible exception of instrumental support, which may allude to possible sociocultural differences in the experience of instrumental support exchanges.

Educational differences in the prevalence of mobility disability in old age: the dynamics of incidence, mortality, and recovery.

OBJECTIVES: Older people with less education have substantially higher prevalence rates of mobility disability. This study aimed to establish the relative contributions of incidence, recovery rates, and death to prevalence differences in mobility disability associated with educational status. METHODS: Data were from 3 sites of the Established Populations for Epidemiological Study of the Elderly, covering 8,871 people aged 65-84 years who were followed for up to 7 years. Participants were classified on years of education received and as disabled if they needed help or were unable to walk up or down stairs or walk half a mile. A Markov model computed relative risks, adjusting for the effects of repeated observations on the same individuals. RESULTS: Differences between education groups in person-years lived with disability were large. The relative risk of incident disability in men with 0-7 years of education (vs. those with 12 or more years) was 1.65 (95% CI = 1.37-1.97) and in women was 1.70 (95% CI = 1.15-2.53). Both recovery risks and risks of death in those with disability were not significantly different across education groups in either gender. DISCUSSION: Higher incidence of disability is the main contributor to the substantially higher prevalence of disability in older people of lower socioeconomic status. Efforts to reduce the disparity in disability rates by socioeconomic status in old age should focus mainly on preventing disability, because differences in the course of mobility disability after onset appear to play a limited role in the observed prevalence disparities.

Temporal and reciprocal relationship between IADL/ADL disability and depressive symptoms in late life.

A strong association between functional disability and depressive symptoms in older people has frequently been reported. Some studies attribute this association to the disabling effects of depression, others to the depressogenic effects of physical health-related disability. The authors examined the reciprocal effects between depressive symptoms and functional disability and their temporal character in a community-based cohort of 753 older people with physical limitations who were assessed at yearly intervals. They compared structural equation models that differed in terms of direction and speed of effects between patient-reported disability in instrumental and basic activities of daily living (IADL/ADLs) and depressive symptoms. The association between disability and depression could be separated into three components: (a) a strong contemporaneous effect of change in disability on depressive symptoms, (b) a weaker 1-year lagged effect of change in depressive symptoms on disability (probably indirect through physical health), and (c) a weak correlation between the trait (or stable) components of depression and disability. IADL/ADL disability and depressive symptoms are thus mutually reinforcing over time. Compensatory forces like effective treatment and age-related adaptation may protect elders against this potential downward trend. To improve quality of life in elderly adults, treatment should target disability when it is new and depression when it is persistent.

Physical disablement concepts for physical therapy research and practice.

Disability, one of modern society's greatest public health problems, affects individuals, families, and society. Understanding the complex process of disablement, therefore, is critical given the current and projected increases in disability. Terminology in the field of disablement continues to breed confusion and controversy across and within disciplines. This article discusses some of the major models that have been developed to guide physical therapy researchers and clinicians in their thinking about disablement. Emphasis is on physical disablement because of its central role in physical therapy research and practice. Detailed descriptions are provided for two disablement formulations. One was developed in the 1960s by sociologist Saad Nagi. The other is the International Classification of Impairments, Disabilities, and Handicaps, developed for the World Health Organization. Both can serve as the basic conceptual architecture for disablement research in physical therapy. Researchers and clinicians need a common vocabulary and language for thinking and speaking about the process of disablement, although it appears premature to reach consensus on any one conceptual approach. Physical therapists should play an active role in guiding future research and scholarship on physical disablement.

Depression and functional disability in chronic pediatric pain.

OBJECTIVES: The primary aim of this study was to describe pain characteristics, coping strategies, depression, and functional disability in children and adolescents with chronic pain and to examine potential factors that are associated with functional disability in a pediatric pain population. The secondary aim of this study was to compare functional disability in two chronic pain conditions: localized musculoskeletal pain and chronic daily headaches. SUBJECTS: The participants in this study were 73 pediatric pain patients with a variety of chronic pain conditions. Subjects in the second part of the study were a subset of patients (N = 44) from the pain clinic sample with chronic localized musculoskeletal pain and a subset of patients (N = 38) from the headache center of the same hospital who had chronic daily headaches. DESIGN: Patients completed self-report measures of pain intensity, depression, coping strategies, coping efficacy, and functional disability. RESULTS: Results indicated that chronic pain had a substantial impact on the children's lives and that depression was strongly associated with functional disability. Maladaptive coping was correlated with depression and disability; however, maladaptive coping was not independently associated with functional disability. A comparison between the two groups found significant differences in pain intensity and functional disability. The localized musculoskeletal pain group reported higher levels of disability and more difficulty coping than the chronic daily headache group. CONCLUSIONS: The implications for treatment of chronic pain in children are discussed with an emphasis on greater attention to developmental issues and their relation to coping, emotional functioning, and disability in pediatric pain. Further research examining differences in coping and disability between different pediatric pain groups is also warranted.

A prospective cohort study of risk factors for disability retirement because of back pain in the general working population.

STUDY DESIGN: A 7-year prospective cohort study of 34,754 employed men and women was conducted. OBJECTIVE: To determine the relative contribution of occupational risk factors, lifestyle factors, comorbidity, and psychological and social factors to the incidence of disability retirement because of back pain in the general working population. SUMMARY OF BACKGROUND DATA: Permanent occupational disability is a serious consequence of a disabling process. Although this condition is a great burden to the individual and extremely costly for society, few population-based studies exist on risk factors for obtaining disability pension because of back pain. METHODS: Patients granted back pain disability pension were ascertained from the national disability register. The exposure variables were taken from a health screening of all the inhabitants in one county: Norway. The participation rate was 72% to 90%. RESULTS: During the follow-up period, 715 individuals (2.1%) were granted a back pain disability pension. In the final combined multivariate model, the strongest predictors for future back pain disability were the occupational risk factor "physically demanding work" (odds ratio [OR], 4.1; 95% confidence interval [CI], 2.7-6.4) and the comorbidity factor "poor general health" (OR, 3.7; 95% CI, 2.4-5.8). "Feeling of being worn out" (OR, 1.7; 95% CI, 1.1-2.4), current smoking (OR, 1.4; 95% CI, 1.2-1.7), and body mass index in the upper percentile (OR, 1.6; 95% CI, 1.2-2) also predicted back pain disability pension. CONCLUSIONS: In a broad public health perspective within a European welfare system, subjects at high risk for future back pain disability pension perceived their work as constantly physically demanding, had health complaints other than back pain, and mostly felt generally tired and worn out. The results indicate that interventions directed toward the painful back alone may be unsuccessful in preventing disability pensions.

Musculoskeletal-related disability in US Army personnel: prevalence, gender, and military occupational specialties.

Research on military populations indicates that musculoskeletal-related disorders represent a prevalent source of outpatient visits, lost work time, hospitalization, and disability. Despite the increasing role of women in the military, little is known regarding the association among military occupations, gender, and disability. The study presented here analyzed 41,750 disability cases to determine: (1) prevalence of work-related musculoskeletal disability, (2) specific jobs associated with greater risk of musculoskeletal disability, and (3) association among gender, job-type, and disability. Results indicate: (1) back-related disorders represent the most prevalent sources of disability, (2) certain occupations were associated with higher disability risk, (3) women experienced higher overall, and musculoskeletal, disability risk, and (4) specific jobs were identified in which women experienced higher rates of musculoskeletal disability. These findings highlight the need to consider the interaction between workplace factors and gender on disability in the military work force.

The transition from acute to subacute and chronic low back pain: a study based on determinants of quality of life and prediction of chronic disability.

STUDY DESIGN: Follow-up study. OBJECTIVES: To document differences between acute and subacute low back pain (LBP) based on the risk of developing chronic disability and on the correlation between pain, disability, and quality of life. SUMMARY OF BACKGROUND DATA: The subacute stage should identify the time in which the risk of developing chronic disability increases and specific measures should be considered, but its definition is currently inconsistent. METHODS: 366 patients were given Visual Analog Scales (VAS) for LBP and referred pain (RP), Roland-Morris questionnaires (RMQs), and EuroQol (EQ) questionnaires on their first visit and 14 and 59 days later. RESULTS: Median duration of pain when entering the study was 4 days (P25, P75: 2,10). Simple correlations among LBP, VAS, and RMQ were r = 0.407 (day 1), 0.688 (day 15), and 0.739 (day 60). Among LBP, VAS, and EQ, r = -0.523, r = -0.701, and r = -0.760. Among RP, VAS, and RMQ, r = 0.280, r = 0.561, and r = 0.583. Between RP, VAS, and EQ, r = -0.306, r = -0.534 and r = -0.600. Between RMQ and EQ, r = -0.650, r = -0.765 and r = -0.815. In 42 patients, disability did not improve throughout the study period, and a prestudy duration of > or = 14 days was the only independent predictor. All these models were significant at the P < 0.007 level. Improvement in quality of life was more likely to occur in patients in which disability improved [odds ratio (OR), 18.29; 95% CI; 8.64, 38.73; P < 0.001]. As opposed to acute patients, in those with a prestudy duration of pain of > or = 14 days, on day 60 RP had no influence on disability, and LBP had no influence on quality of life. CONCLUSION: LBP influences disability and quality of life more than RP. Disability is predicted by pain duration and quality of life is predicted by disability, but pain severity predicts neither one of them. Changes related to determinants of disability and quality of life, and to the prediction of chronic disability, appear 14 days after the onset of pain, supporting that cutoff point for considering a patient as being subacute.

Incidence of and predictors for chronic disability in activities of daily living among older people in Taiwan.

OBJECTIVES: To estimate the incidence of chronic activities of daily living (ADL) disability and to analyze the sociodemographic, health status, adverse lifestyle, and leisure-time physical activity predictors for chronic ADL disability. DESIGN: We recruited a cohort of community-dwelling older people in Taipei, Taiwan, who were not ADL disabled in August 1993, and we followed them until August 1996. SETTINGS AND PARTICIPANTS: The study subjects were 1321 community-dwelling people aged 65 years or older who were ADL intact at the initial interview in August 1993. The study sample was a subset of a probability sample (n = 1583) randomly selected from household registrations in the four districts of the Taipei metropolitan area. MEASUREMENTS: Baseline information regarding various factors potentially associated with the development of chronic ADL disability was assessed and collected at the beginning of the study. Study participants were assessed annually for ADL function by a structured home interview using a six-item scale. Participants who were unable to perform independently at least one of the six items--eating, bathing, dressing, toileting, transfers, and walking inside the house--for more than 3 months were considered chronically ADL disabled. Cox proportional hazard regression models were utilized to examine the independent effect of the potential predictors on risk of chronic ADL disability. RESULTS: During the 3-year study period, 145 (11.0%) participants developed chronic ADL disability, 58 (4.4%) participants were lost to follow-up, and 83 (6.3%) participants died. Multiple hazard regression analysis showed that individuals aged 70 to 79 years or older than age 80 had increased risk of ADL disability (relative risk: 2.05 (95% confidence interval (CI), 1.35-3.11) and 3.89 (95%CI, 2.33-6.50), respectively) compared with those participants younger than age 70. Risk of chronic ADL disability was inversely associated with routine exercise (RR = 0.52; 95% CI, 0.39-0.68). CONCLUSIONS: Age is the most significant predictor of chronic ADL disability. Lack of routine exercise is also a significant predictor of ADL disability in older adults.

[Characteristic situation on prevention of nosocomial infection in the hospital for the severely multi-disabled--experiences in care and treatment of 4 kinds of viral hepatitis].

We experienced Hepatitis A, B, C and fulminant hepatitis due to Herpes simplex virus type 1 (HSV-1) in our hospital for the severely multi-disabled (SMD) who had both severe motor and intellectual disabilities, and some of whom might be further complicated by blindness and/or deafness. In this hospital, 100 SMDs are hospitalized. Case 1: The disabled, 25 year old male, was transmitted Hepatitis A from a nurse. Case 2: The disabled, 60 year old female carrier of Hepatitis B virus (HBV) who has been cared for more than 10 years. Case 3: The disabled, 46 year old male carrier of Hepatitis C virus (HCV) (RNA type 3), has been cared for more than 4 years. Case 4: The disabled, 39 year old male, had a fever of 39 degrees C for 9 days and suddenly died. He was diagnosed as fulminant hepatitis due to HSV-1 by necropsy. The hospitals for SMD are characteristic in prevention of nosocomial infections; 1) The disabled infected is not aware of the fact that he or she is the source of infection and that the other disabled living with him or her are in risk of infection, because of their severe mental condition. 2) All of the disabled need complete or incomplete helps for activities of daily life (ADL), so that the disabled who is the carrier of some pathogen constantly gives risk of infection to staffs, including medical staffs (doctor, nurse and therapist), psychologist and helpers by bloody secretion from wounds, saliva, urine, feces as well as menstrual blood. 3) If a carrier of some pathogen is hospitalized, the staffs should serve under risk of infection involving blood-mediated infectious disease for many years, because SMDs are permitted lifelong stay in the hospitals for SMD, which also play a role of care house or institution, by public expense in Japan. In case of an outbreak of Hepatitis A, nosocomial infection ended in the original case (a nurse), another nurse and a case of the disabled by general treatment and care against communicable diseases of the digestive organs. In care of HBV and HCV carriers, an ordinary program to prevent nosocomial infection has been practiced in our hospital more strictly than in conventional hospital. HBV vaccine is injected to staffs caring the HB carriers who are negative on HBs antibody. Thus, during more than 10 years of care of HBV carrier and more than 4 years of care of HCV carrier, nosocomial infection has never been experienced clinically as well as serologically in our hospital. However, we have often been faced by difficulty to guarantee QOL (quality of life) of the carriers, because carrier states of HBV or HCV have been long-lasting and they have been occasionally and inevitably separated physically and/or psychologically in order to prevent nosocomial infection. In case 4, it was suspected that previously latently infected HSV-1 would be activated by another viral infection which had elicited fever for 9 days before death. The patient had neither history nor sign or symptom of immunodeficiency and had never been given drugs known as to be immunosuppressive as side effect.

Injuries among disabled children: a study from Greece.

OBJECTIVE: To compare the differential implications of sociodemographic and situational factors on the risk of injury among disabled and non-disabled children. DESIGN: Data from the Emergency Department Injury Surveillance System (EDISS) were used to compare, in a quasi case-control approach, injured children with or without disability with respect to sociodemographic, event and injury variables, and to estimate adjusted odds ratios for the injury in a disabled rather than a non-disabled child. SETTING: Two teaching hospitals in Athens and two district hospitals in the countryside that participate in the EDISS. PATIENTS: In the five year period 1996-2000, 110 066 children were recorded with injuries; 251 among them were identified as having a motor/psychomotor or sensory disability before the injury event. INTERVENTIONS: None. MAIN OUTCOME MEASURES: Mechanism of injury, type of injury, risk-predisposing socioeconomic and environmental variables, odds ratio for injury occurrence. RESULTS: Falls and brain concussion are proportionally more common among disabled children, whereas upper limb and overexertion injuries are less common among them. Urban environment, migrant status, and cold months are also associated with increased odds for injuries to occur among disabled rather than non-disabled children. The odds ratio for the occurrence of an injury among disabled children increases with increasing age. CONCLUSIONS: The results of the study provide the information for the targeting of trials of preventive measure in disabled children at increased risk of severe injuries.

Socioeconomic status and the expectation of disability in old age: estimates for England.

OBJECTIVES: The longer life expectancy in old age of more privileged socioeconomic groups is well established, but less clear is whether the net effect of additional years of life is a lengthened, stable or reduced duration of disability. Estimates of healthy and disabled life expectancy (using definitions including dependency in activities of daily living and cognitive impairment) were made, contrasting occupational classes I and II (professional and managerial) with the rest. DESIGN: Disability prevalence was estimated from the Medical Research Council Cognitive Function and Ageing study. Sullivan's method was used to calculate health expectancy. SUBJECTS: 10,377 people aged 65 years or over in Cambridgeshire, Newcastle, Nottingham and Oxford. Subjects were classified as disabled if they had evidence of dementia (using the Automated Geriatric Examination Computer Assisted Taxonomy) or scored 11 or more on the modified Townsend Disability scale, at baseline screen. RESULTS: The prevalence of disability overall and need for "constant care" was lower in both men and women in social classes I and II compared with the rest. Men aged 65 to 69 in classes I and II can expect nearly 14 years of life free of disability compared with 11.5 years for those in classes III to V: for women the equivalent expectations are 15.5 and 13.8 years. Men aged 65 to 69 in classes I and II can also expect a shorter duration of disability: 1 year compared with 1.6 years for classes III to V. In women expectation of disability is higher overall, but shows little difference by occupational class. CONCLUSIONS: Relatively privileged socioeconomic groups in England, especially men, can expect fewer years of disability despite longer overall life expectancy. These findings lend weight to optimistic scenarios for the future numbers of older people with disability.

Disability and quality of life in Charcot-Marie-Tooth disease type 1.

OBJECTIVES: Charcot-Marie-Tooth disease type I (CMT1) is a hereditary sensorimotor neuropathy causing variable degrees of handicap. The risk for relevant disability in respect to genetic counselling is unknown. An attempt was made to define it. METHODS: Disability and ambulation of 50 patients with CMT1 were scored by the Hauser ambulation index score and the Rankin scale. Rankin score 2 was subdivided into 2a (independent without relevant slowness) and 2b (independent, though at the cost of excessive time consumption). The sickness impact profile was assessed and compared with patients 6 months after stroke who were without mental deficit. To define at which degree sickness and disability become relevant for genetic counselling, the patients were asked whether they would refrain from childbearing if the children were at risk of inheriting a disease that caused as much disability as they experienced themselves. RESULTS: Subdivision of Rankin score 2 was reliable and improved validity. High disability significantly predicted an attitude against childbearing (stepwise logistic regression) only with this subdivision. Thirty six per cent of the patients voted against childbearing. The cut off for relevant disability in respect to childbearing was a Rankin score higher than 2a, which was present in 44% of the patients. Psychosocial impact was comparable with patients with stroke and similar disability. Depression was present in 18% of the patients. CONCLUSION: Subdivision of Rankin score 2 is recommended for the assessment of longstanding disability in neuromuscular disorders. Disability becomes relevant for the attitude towards childbearing as soon as everyday activities become markedly slow (Rankin score 2b). Relevant disability occurred in 44% of the patients. Emotional stress in CMT is similar to that of patients with stroke and comparable disability.

Separating attention deficit hyperactivity disorder and learning disabilities in girls: a familial risk analysis.

OBJECTIVE: Familial risk analysis was used to clarify the relationship in girls between attention deficit hyperactivity disorder (ADHD) and learning disabilities in either mathematics or reading. METHOD: The authors assessed the presence of ADHD and learning disabilities in 679 first-degree relatives of three groups of index children: girls with ADHD and a comorbid learning disability, girls with ADHD but no learning disabilities, and a comparison group of girls without ADHD. RESULTS: The risk for ADHD was similarly higher in families of ADHD probands with and without learning disabilities; both groups had significantly higher rates of ADHD than did families of the comparison girls. In contrast, only among relatives of ADHD probands with a learning disability was there a higher risk for learning disabilities. A strong (although statistically nonsignificant) difference emerged that suggested at least some degree of cosegregation of ADHD and learning disabilities in family members. There was no evidence of nonrandom mating between spouses with ADHD and learning disabilities. CONCLUSIONS: These results extend previously reported findings regarding the relationship of ADHD and learning disabilities to female subjects and raise the possibility that, in girls, the relationship between ADHD and learning disabilities is due to shared familial risk factors.
