Subcortical vascular lesions and functional recovery in older patients with gait disorders.

This study aimed to assess whether subcortical vascular lesions (SVLs) predict functional recovery after rehabilitation in elderly patients with gait disorders (GD) due to multiple etiology (GD-ME). All patients consecutively admitted with GD-ME (n=103) in our Rehabilitation and Aged Care Unit (RACU) underwent a standardized rehabilitative program. The outcome measure was the Barthel Index (BI) Relative Functional Gain (RFG), a measure of improvement adjusting for baseline functional level. Potential predictors included cognition, depression, functional and nutritional status, physical health, occurrence of adverse clinical events during hospital stay, and SVLs, assessed with a validated visual rating scale based on brain CT scans. Predictors were divided into quartiles and the association with RFG was assessed. In a multivariate linear regression model, SVLs maintained its predictive power on RFG after adjustment for age, gender, and adverse clinical events, which was the only variable associated to RFG in the bivariate model (adjusted p=0.002 for trend). The study shows that SVLs is a predictor of functional recovery in elderly patients with GD-ME.

Functional correlates of Apolipoprotein E genotype in Frontotemporal Lobar Degeneration.

BACKGROUND: It has been recently demonstrated that in Frontotemporal Lobar Degeneration (FTLD) memory deficits at presentation are commoner than previously thought. Apolipoprotein E (ApoE) genotype, the major genetic risk factor in sporadic late-onset Alzheimer Disease (AD), modulates cerebral perfusion in late middle-age cognitively normal subjects. ApoE epsilon4 homozygous have reduced glucose metabolism in the same regions involved in AD. The aim of this study was to determine whether ApoE genotype might play a key-role in influencing the cerebral functional pattern as well as the degree of memory deficits in FTLD patients. METHODS: Fifty-two unrelated FTLD patients entered the study and underwent a somatic and neurological evaluation, laboratory examinations, a brain structural imaging study, and a brain functional Single Photon Emission Tomography study. ApoE genotype was determined. RESULTS: ApoE genotype influenced both clinical and functional features in FTLD. ApoE epsilon4-carriers were more impaired in long-term memory function (ApoE epsilon4 vs. ApoE non epsilon4, 6.3 +/- 3.9 vs. 10.1 +/- 4.2, p = 0.004) and more hypoperfused in uncus and parahippocampal regions (x,y,z = 38,-6,-20, T = 2.82, cluster size = 100 voxels; -32,-12,-28, T= 2.77, cluster size = 40 voxels). CONCLUSION: The present findings support the view that ApoE genotype might be considered a disease-modifying factor in FTLD, thus contributing to define a specific clinical presentation, and might be of relevance for pharmacological approaches.

Effects of cholinesterase inhibitors appear greater in patients on established antihypertensive therapy.

INTRODUCTION: There is increasing evidence that hypertension may contribute to development of dementia. Studies show that blood pressure lowering therapy might protect against cognitive deterioration and that antihypertensive treatment reduce the incidence of dementia. AIM: We hypothesize that administration of cholinesterase inhibitors (AChEis) to patients with Alzheimer's Disease (AD) receiving antihypertensive medications therapy would result in clinical benefits for a period of 40 weeks in routine clinical practice. METHODS AND MATERIALS: Patients with possible or probable AD were enrolled from 16 Alzheimer evaluation units (UVA) of Brescia and Cremona (Northern Italy). Patients treated with donepezil, rivastigmine and galantamine for 40 weeks independently of dosages were selected. Patients were evaluated at baseline (T0), 4 weeks (T1), 16 weeks (T2) and 40 weeks (T3). RESULTS: 416 patients completed the study at 40 weeks; of these 255 were 'non users' while 161 utilized antihypertensive drugs ('users'). The mean change in MMSE score from baseline to week 40 demonstrate that antihypertensive-treated patients improved by 0.7 points while patients receiving only AChEis remain stables. Analyzing separately patients (n = 183) that ameliorate (responders) on cognition at T3 ( >/= 1 point MMSE score increase) a significant differences in favor of 'users' antihypertensive drugs over 'non users' on cognition at weeks 16 and 40 has been demonstrated. In particular, at T2 the mean change of MMSE from baseline in 'users' was 3.2 +/- 2.6 vs 'non users' 2.2 +/- 2.3 ( p = 0.016) and at T3 was 3.5 +/- 2.5 vs 'non users' 2.0.2.7+/-1.6 ( p = 0.018). Antihypertensive drugs were independently associated with cognitive improvement in responder patients treated with AChEis (95% CI: 0.41-1.79; p = 0.002). CONCLUSION: Antihypertensive medications in AD patients treated with AChEis are associated with an independent improvement on cognition after 40 weeks of treatment.

Results of a multi-level therapeutic approach for Alzheimer's disease subjects in the "real world" (CRONOS project): a 36-week follow-up study.

BACKGROUND AND AIMS: Recently, the Italian Ministry of Health started a national project (CRONOS project), aiming at assessing how a multi-level therapeutic approach--including 2-year free-of-charge treatment with cholinesterase inhibitors (ChE-I), pharmacologic and non-pharmacologic management of behavioral disorders, periodic multi-dimensional assessment, and informal caregivers' counseling-performs in subjects with mild-to-moderate Alzheimer's disease (AD). Five hundred and three Alzheimer Evaluation Units (AEUs) were instituted for this purpose all over Italy. In this paper we present the results of this approach in a large population of AD subjects followed for 36 weeks by 14 AEUs in Eastern Lombardy, Italy. METHODS: The project lasted for two years (September 2000-September 2002). Subjects eligible for the CRONOS project had a diagnosis of probable AD, a Mini Mental State Examination (MMSE) score at baseline ranging from 10 to 26, and onset of cognitive disorders between 40 and 90 years of age. Periodic clinical and multi-dimensional assessments, including MMSE, Activities of Daily Living (ADL) and Instrumental Activities of Daily Living (IADL) were made at 12 and 36 weeks; ChE-I doses, psychotropic and antidepressant drugs were also re-assessed at all clinical examinations. Caregivers were instructed about dementia and drug-related problems. RESULTS: Of the 808 subjects who completed the 36-week follow-up, 441 were naïves (i.e., never previously treated with ChE-I drugs) and 367 non-naïves. At 12 weeks, both naïves (mean variation from baseline = 0.8 points) and non-naïves (mean variation from baseline = 0.5 points) improved their MMSE scores, while at 36 weeks only naïves improved (mean variation from baseline = 0.1) and non-naïves decreased (mean variation from baseline = -1.2). The IADL and ADL scores progressively and mildly declined from baseline to the 36th week (ADL, mean variation from baseline = -0.5 for naïves, -0.3 for non-naïves; IADL = -0.7 for naïves, mean variation from baseline = -0.4). However, when the MMSE, ADL and IADL variations were controlled for age, sex and education, no significant time effect was found (MMSE, Wilks' lambda p = 0.34; ADL, Wilks' lambda p = 0.25; IADL, Wilks' lambda p = 0.3, respectively). These patterns were apparently unrelated to ChE-I doses. Neuroleptic use doubled in naïves and antidepressants increased in both groups. CONCLUSIONS: This multi-level therapeutic approach seems to slow down progression in cognitive and functional performance, in both naïve and non-naïve subjects. The possibility of recurrent examinations by specialized physicians, accurate, lose management of psychotropic drugs, and informal counseling to caregivers probably aid in achieving such results in a "real world" population of AD elderly subjects living at home. Future studies are needed to assess whether a multi-level therapeutic approach including higher ChE-I dose may perform better in these subjects.

Blunted reduction in night-time blood pressure is associated with cognitive deterioration in subjects with long-standing hypertension.

OBJECTIVE: Data about the relationship of blunted reduction of night-time blood pressure (BP) with cognitive deterioration (CD) are conflicting. This study aims to explore this possible association in elderly people with long-standing hypertension. METHODS: Twenty-six hypertensive subjects consecutively admitted to a rehabilitation unit over a six-month period were recruited. Exclusion criteria concerned all clinical conditions potentially related to BP variability or leading to CD. All patients underwent a clinic and 24-h BP non-invasive monitoring assessment of BP, as well as a cognitive assessment with the Mini Mental State Examination (MMSE). The presence of cerebrovascular disease (CVD) was assessed on CT films, with a standardized visual rating scale. RESULTS: Blunted reduction of both systolic and diastolic night-time BP were significantly associated with poorer cognitive performances (r=0.61, p=0.001 for systolic; and r=0.57, p=0.002 for diastolic, respectively). In a multiple regression model, blunted reduction of night-time BP (B=0.17, [95% confidence intervals: 1.1-1.3], p=0.008 for systolic; and B=0.15, [95% confidence intervals: 1.0-1.3], p=0.02 for diastolic) independently predicted poorer cognitive performances. CONCLUSIONS: In subjects with long-standing hypertension the blunted reduction of night-time BP is independently associated with lower cognitive performances.

Subcortical vascular lesions predict functional recovery after rehabilitation in patients with L-dopa refractory parkinsonism.

OBJECTIVES: To identify predictors of functional recovery after an intensive rehabilitation training in patients with gait disturbances and refractory parkinsonism. DESIGN: Observational study. SETTING: A hospital geriatric rehabilitation department ("Ancelle della Carità" hospital of Cremona). PARTICIPANTS: Thirty-eight subjects (mean age+/-standard deviation of 78.9+/-6.5; 66% women) with gait disturbances and L-dopa refractory parkinsonism consecutively admitted to a rehabilitation unit within 6 months were recruited. Exclusion criteria were obvious musculoskeletal disorders (severe leg arthritis, hemiparesis, recent stroke), recent surgery, delirium, physical impairment from other identifiable causes, and missing computed tomography (CT) scan. All subjects received an intensive standardized rehabilitative program including conventional physical therapy and specific gait training. MEASUREMENTS: The outcome measure of the rehabilitation training was the gain between admission and discharge on the Unified Parkinson Disease Rating Scale (delta-UPDRS). The following potential predictors were assessed using comprehensive geriatric assessment: physical health (Charlson Comorbidity Index, number of drugs), cognitive performance (Mini-Mental State Examination (MMSE)), functional status (Tinetti scale), depressive symptoms (Geriatric Depression Scale), nutritional status (serum albumin and body mass index), and subcortical cerebrovascular load (four classes of increasing severity based on diffuse leukoariosis, patchy lesions of the white matter, and lacunas on CT scan). Multivariate logistic regression with fixed adjustment for age, cognitive performance, and UPDRS on admission and stepwise selection of variables were used to identify independent predictors. RESULTS: Patients were divided into two groups of equal size based on the delta-UPDRS (high and low functional recovery: delta-UPDRS >8 and </=8, respectively). Of all variables, only subcortical cerebrovascular load predicted functional recovery at discharge (odds ratio adjusted for age, MMSE, and UPDRS on admission=2.3, 95% confidence interval=1.0-5.1). The adjusted proportion of patients with high functional recovery decreased with increasing subcortical cerebrovascular load: 83%, 61%, 44%, and 27% (adjusted P for trend=0.047). CONCLUSION: Subcortical cerebrovascular load is a predicting factor of successful rehabilitation in patients with L-dopa refractory parkinsonism.
