Quality of life: the family and Alzheimer's disease.

AD possesses unique features that make caregiving particularly burdensome. The quality of life of the caregiver is inevitably affected, but there are many intervening variables such as the strength of the existing relationship and the presence of a social support system that can mediate the outcome. Health professionals can play a vital role by providing a continuous source of advice, support, and help to assist the caregiver in the difficult task of tending a loved one during this long and stressful illness.

Cross-cultural studies in Alzheimer's disease.

The search for risk factors for Alzheimer's disease would be greatly enhanced by identification of populations with significantly different prevalence rates, particularly if these populations consisted of ethnic groups now living in different environments and cultures. Evidence is presented that two such groups are worthy of further study: subjects of African origin living in Africa and in the West and Native Americans living on and off reserves.

Leuko-araiosis: description and clinical correlates.

The term leuko-araiosis as predicted by Hachinski may now have outlived its usefulness. Careful delineation of the white matter changes seen in MR imaging by use of the MR characteristics and by the location of the lesions may reduce the apparent heterogeneity of the associate clinical and neuropathological findings. As currently defined, leuko-araiosis is seen in aggregate more commonly in subjects with cerebro-vascular disease or with cerebro-vascular risk factors but it is a common finding associated with aging in otherwise normal, healthy elderly subjects. Its clinical significance as an isolated finding in these populations should therefore be treated cautiously. Its appearance should alert the physician however to seek for and treat potential cerebro-vascular risk factors.

A study of anxiety/depressive symptoms of medical students, house staff, and their spouses/partners.

Symptoms of anxiety/depression and suicidal ideation were studied in medical students, house staff, and their spouses/partners in a large midwestern school by means of an anonymous questionnaire. A total of 634 medical students and 227 house staff completed the questionnaire. A significantly higher proportion of female trainees than male trainees reported symptoms of anxiety/depression (41% compared with 27%). This difference between men and women was most marked during residency training. The proportion of men reporting anxiety/depressive symptoms declined between medical school (33%) and residency (10%). No such decline occurred with women (medical students 42%, residents 37%).

Foci of increased T2 signal intensity in MR images of healthy elderly subjects. A follow-up study.

An 18-month follow-up study was conducted on 26 healthy elderly subjects with and without foci of increased T2 signal intensity on MR imaging. The subjects did not differ with respect to health status or cognitive performance as measured by the Cognitive Subscale of the Cambridge Mental Disorders of the Elderly Examination and the Mini Mental State Examination at follow-up. There was a significant decline in performance on the Digit Symbol Substitution Test in subjects who had evidence of T2 foci compared to the performance of subjects without T2 foci. This may indicate that the presence of T2 foci is correlated with subtle difficulties in learning and memory.

A rapid column chromatographic procedure for the routine measurement of taurine in plasma of normals and depressed patients.

A rapid method has been developed for the routine measurement of taurine in plasma. A preliminary clean-up step has made it possible to assay multiple samples in a relatively short period of time using the excellent sensitivity and specificity of the analytical column of the automatic amino acid analyzer. The speed and specificity of the method permits its use for the routine measurement of taurine in blood samples. Employing this method, a value of 45+/-4nmol taurine per ml platelet free plasma (mean+/-S.E.M.) was obtained for normal healthy adults. Analysis of plasma from depressed patients who are free of drugs as well as from depressed patients under treatment with drugs gave values of 29+/-2 and 25+/-3 nmol taurine per ml platelet free plasma (mean+/-S.E.M.), respectively.

Depression of elderly outpatients: primary care physicians' attitudes and practice patterns.

OBJECTIVE: To determine primary care physicians' attitudes and practice patterns concerning the diagnosis and treatment of depression in elderly outpatients. DESIGN: Survey of primary care physicians' attitudes using a 22-item questionnaire. Current practice patterns were identified from a computerized medical record system. SETTING: Academic primary care group practice at an urban ambulatory care clinic. PATIENTS/PARTICIPANTS: Thirty-five faculty general internists and 118 resident internal medicine physicians who had cared for 2,759 patients 65 years of age and older in the previous year. MEASUREMENTS AND MAIN RESULTS: Attitudes: Eighty percent of all physicians considered the diagnosis and treatment of depressed elderly patients to be their responsibility. Fifty-five percent of the internists felt confident in accurately diagnosing depression, and 35% felt confident in prescribing antidepressants for this population. Residents reported more difficulties in dealing with depressed elderly patients than did faculty. Practice patterns: Of patients greater than or equal to 65 years old, 8% were prescribed antidepressants, 5.4% had current diagnoses of depression, and 2% were seen for evaluation by psychiatry professionals. Age was negatively correlated with depression diagnosis, antidepressant drug use, and psychiatry evaluation. CONCLUSIONS: Internists in this primary care group practice accept responsibility for the treatment of depressed elderly patients but perceive their clinical skills as inadequate and are frustrated with their practice environment. Interventions aimed at improving the diagnosis and treatment of depressed elderly patients may be more effective if they are able to improve knowledge, attitudes, and the practice environment.

Foci of increased T2 signal intensity on brain MR scans of healthy elderly subjects.

Foci of increased T2 signal intensity were found on brain MR scans in 16 (59%) of 27 healthy elderly volunteer subjects, ages 63 to 86 years old. These foci were not related to cognitive function or cerebrovascular risk factors; instead, they were highly correlated to age, being present in 11 of 11 subjects aged 75 years and over.
