Evaluation of the relative efficacy of three screening instruments for depression and anxiety in a group of stroke patients was undertaken as part of the Perth community stroke study. Data are presented on the sensitivity and specificity of the Hospital Anxiety and Depression Scale (HAPS), the Geriatric Depression Scale and the General Health Questionnaire (GHQ) (28-item version) in screening patients 4 months after stroke for depressive and anxiety disorders diagnosed according to DSM-III criteria. The GHQ-28 and GDS but not the HADS depression, were shown to be satisfactory screening instruments for depression, with the GHQ-28 having an overall superiority. The performance of all 3 scales for screening post-stroke anxiety disorders was less satisfactory. The HADS anxiety had the best level of sensitivity, but the specificity and positive predictive values were low and the misclassification rate high.

In this double-blind, randomized study the efficacy of the ergoloid compounds, co-dergocrine mesylate and nicergoline, in the rehabilitation of patients with ischaemic stroke was investigated. A group of 30 patients was treated daily with 60 mg nicergoline, orally, and a second group of 27 patients was given 1.8-6 mg co-dergocrine mesylate, orally or intramuscularly, daily (depending on the time since the initial ischaemic insult) for 6 months. Outcome measures included: motoricity index (limb function); Sandoz Clinical Assessment Geriatric (SCAG) scale; psychometric tests to assess functions such as attention, psychomotor performance, perception and sensory and short-term memory; conventional and computerized electroencephalography; and P300 and reaction time measures. The results showed improvements in some aspects such as limb function (P < 0.05), SCAG score (P < 0.01) and some electrophysiological parameters (P < 0.01) after treatment with both drugs. Though statistically significant most of the changes were not large. The efficacy of both drugs was qualitatively similar. The quantitative difference in some aspects in favour of nicergoline could be attributed to differences in the mechanisms of action of the two drugs, although it is also possible that the difference may reflect the dosages used. Nootropic drugs may induce a condition that facilitates the effects of cognitive training.

A cross-sectional designed study was done at Siriraj Hospital from 1990 to 1994 to determine the prevalence of dementia in Thai stroke survivors. Two hundred and twelve Thai stroke (both hemorrhage and infarction) survivors (132 males and 80 females) were enrolled in this study. The mean age of the study group was 62.78 (S.D. 11.12) years with the mean duration of stroke suffering of 2.09 (S.D. 2.74) years. All patients were screened for depression by using Thai Geriatric Depression Scale and patients with Alzheimer disease were excluded from the study. The Thai Mental State Examination (TMSE) is a standard test used in this study to identify stroke patients with dementia. Seventy stroke patients (33.02 per cent) scored below 23 points (cut-off point for dementia) and considered as dementia. Forty patients (18.88 per cent) scored below 20 points and were considered as having severe dementia, 30 patients (14.15 per cent) scored between 20-22 points (classified as mild to moderate dementia). Fifty-eight patients (27.36 per cent) were in the borderline group as they had TMSE scores between 23-25 points. Eighty four patients (39.62 per cent) of stroke survivors were determined as nondemented as their TMSE scores were over 25 points. The items of cognitive function tests in TMSE which were severely impaired in demented group were recall and calculation whereas registration and attention were relatively unaffected. Orientation and language were moderately impaired in the demented group.(ABSTRACT TRUNCATED AT 250 WORDS)

Although numerous studies have examined the prevalence of depression after stroke and its relationship to functional outcome, minimal research attention has been focused on depression in the acute inpatient rehabilitation setting. Fifty-one consecutive admissions to a geriatric rehabilitation unit were screened for depression using the Geriatric Depression Scale at both admission and discharge. Depressed v nondepressed patients were compared on the following variables: age, length of stay (days), admission Functional Independence Measure (FIM) score, discharge FIM score, change in FIM score, Mini-Mental State Exam score, and discharge to nursing home v home. Depression was prevalent in 29.4% at admission. Depression at admission was not associated with any significant differences in the above variables, but patients classified as depressed at discharge had lower FIM scores at both admission and discharge. Clinical implications and recommendations for future research are discussed.

We performed a prospective observational study using a stroke register, case-note review and survey of carers with 6 months of follow-up in two adjacent health districts in East London. District 1 was a teaching district and had no special stroke service; District 2 had a comprehensive stroke service comprising stroke unit, review of all stroke admissions and community follow-up. Three hundred and sixty-one consecutive patients with stroke admitted to hospital and 103 carers were surveyed at 6 months from admission using the Royal College of Physicians (London) Stroke Audit standards. We also assessed mortality, disability, perceived health, mood, and satisfaction with services 6 months after stroke, carer mood, perceived health and satisfaction with services. The standard of care was below that set by the Royal College of Physicians of London in both districts and there were no significant differences between the districts in age-standardized mortality at 1 and 6 months, Barthel score, extended ADL score, Geriatric Depression score, Nottingham Health Profile score and patient satisfaction with services at 6 months. Carer outcomes did not differ between districts. Service costs, particularly costs of rehabilitation services, were much lower in District 2. A comprehensive district stroke service was not associated with major differences in patient outcomes or standards of care. This may have been because the non-random nature of the comparison meant that the patients differed in other ways than in the nature of treatment. Caution is needed when using these techniques in making purchasing decisions.

A comparative community-based study of quality of life (QOL) in the elderly was carried out between two Japanese rural towns, Kahoku and Yaku.QOL, which included the subjective sense of health, appetite, sleep at night, mood, memory, family relationships, friendship, economic condition, life satisfaction and happiness was assessed using a visual analogue scale (VAS) as well a Geriatric depression Scale (GDS), a variety of neurobehavioral function tests, and a questionnaire about activity of daily living (ADL). Subjects were all the eligible elderly aged over 75 years in both communities. Inter-rater reproducibility in VSA was more reliable than that in GDS. Life satisfaction and a subjective sense of happiness highly correlated with mood, family relationships, friendship and economic condition. GDS and VAS significantly correlated with family relationships, active participation in a group and economic condition, however, they did not correlated with age. The subjective sense of happiness correlated with ADL and steadiness of walk as assessed by neurobehavioral function tests. Living style correlated with VAS in the male elderly, but not female. Each score in VAS for family relationships, friendship, economic condition, life satisfaction and subjective sense of happiness was significantly higher in the elderly in Yaku than in Kohoku. The diseases which elderly people wanted to avoid were dimentia cancer, stroke, and cardiovascular disease in that order. In conclusion, QOL in the elderly population was influenced by disease, neurobehavioral functions, especially walking function, gender difference, lifestyle as well as cultural environment.

The aim was to determine the handicap experienced by subjects one year after a stroke, and assess the acceptability, validity, and reliability of a new handicap measurement scale. A cross sectional survey of 141 survivors of a cohort of consecutive hospital admissions with acute stroke was undertaken. The London handicap scale (a new health outcome measurement scale), Barthel index, Nottingham extended activities of daily living scale, Nottingham health profile, Geriatric depression score, and a global life satisfaction scale were used. 94 subjects (67%) responded to a single mailing; 89 (95%) responses were usable. Mean handicap was 0.40 (range 0.06-1.0, SD 0.20) on a scale of 0 (maximum handicap) to 1 (no handicap). All handicap dimensions showed a wide range of problems, with physical independence and occupation particularly affected. Correlations between handicap score and other outcome measures were all in the expected direction and of about the strength expected (0.36 < r < 0.69). The reliability coefficient was 0.91, limits of agreement +/- 0.19. The measurements demonstrated substantial handicap one year after a stroke, reflecting considerable unmet rehabilitation needs. The scale proved acceptable to subjects, and the results were consistent with good validity.

The 26-kDa protein encoded by the bcl-2 gene is a regulator of cell survival and blocks cell death induced by numerous stimuli. Amyloid beta protein (ABP) and glutamate are believed to play important roles in the neuronal cell death that occurs in Alzheimer's disease and stroke, respectively. Glutamate induces apoptosis in some neuronal cell systems, but it remains controversial whether ABP-mediated cell death occurs through apoptosis or necrosis. To further explore the pathways for cell death that are activated by these neurotoxins, we examined the effects of elevated levels of the p26-Bcl-2 protein on the susceptibility of neuronal cell lines to killing by glutamate and ABP. Gene transfer methods were used to elevate p26-Bcl-2 protein levels in the rat nerve lines PC-12 and B50 and the human neuroblastoma IMR-5. Bcl-2 protected all 3 cell lines from glutamate induced cell death but had no effect on killing mediated by ABP.

Novalvular (nonrheumatic) atrial fibrillation (NVAF) is the most common cardiac condition associated with presumed embolic stroke, accounting for approximately half of the cardiogenic embolic infarctions. Of autopsied stroke patients in the Tokyo Metropolitan Geriatric Hospital, cerebral infarction was found in 75%, intracranial hemorrhage in 19%, and coexisting cerebral hemorrhage and cerebral infarction in 6%. Twenty-eight percent of the cerebral infarctions were embolic infarctions of cardiac origin, 56% of which were caused by NVAF. The incidence of cardiogenic brain embolism ranged from 6 to 23% of the ischemic strokes, and NVAF is the most frequent substrate for brain embolism. Atrial fibrillation increases in its incidence with increasing age. Chronic AF was observed in 10%, and paroxysmal AF in 7% of the autopsied elderly patients. Most of them were nonrheumatic AF. Twenty-two percent of the AF patients had large cerebral infarction, and 15% had medium-sized cortical infarction at the autopsy. NVAF is a very important cause of fatal massive cerebral infarction in the elderly. Of 56 patients with fatal massive cerebral infarction who died within 2 weeks after the strokes, 25 (45%) had embolic stroke associated with NVAF. Anticoagulant therapy prevents recurrent cerebral embolism of cardiac origin. The proper time to initiate anticoagulant therapy following cardiac brain embolism is controversial. Immediate initiation of anticoagulant therapy can reduce the early recurrence, but can result in secondary brain hemorrhage or hemorrhatic transformation. Patients with NVAF may have a lower risk of recurrence during the first 2 to 4 weeks following the initial embolic stroke compared with other cardioembolic sources. Cerebral embolism with NVAF can recur during a long period.(ABSTRACT TRUNCATED AT 250 WORDS)

A cross-sectional design study was done at Siriraj Hospital from 1990 to 1994 to determine the prevalence of dementia in Thai patients with Parkinson's disease. There were 81 males and 51 females with a male to female sex ratio of 1.59:1. One hundred and thirty two patients with Parkinson's disease were enrolled in this study. The mean duration of illness was 3.5 (S.D. 3.53) years. All patients were screened for depression by using the Thai Geriatric Depression Scale and patients with Alzheimer's disease or stroke were excluded from the study. The Thai Mental State Examination (TMSE) is a standard test used in this study to identify dementia in Thai patients with Parkinson's disease. Thirty four patients (25.76 per cent) scored TMSE below 23 points (cut-off point for dementia) and were considered as having dementia. Twenty four patients (18.18 per cent) scored below 20 points and were considered as having severe dementia, 12 patients (9.09 per cent) scored between 20-22 points (classified as mild to moderate dementia). Thirty seven patients (28.03 per cent) were in the borderline group as they had TMSE scores between 23-25 points. Fifty nine patients (44.70 per cent) were determined as nondemented as their TMSE scores were over 25 points. The items of cognitive function tests in TMSE which were severely impaired in the demented group were recall, attention and calculation whereas registration was relatively unaffected. Orientation and language were moderately impaired in the demented group. Dementia in Thai patients with Parkinson's disease is a significant problem for long term care of patients because of its high prevalence (one-fourth of all patients) and nearly one-fifth had severe dementia. Prompt recognition and proper management of dementia are required for family members and medical personnel to handle patients with Parkinson's disease.
