- BACKGROUND: Previous studies that have assessed whether the presence of depressive symptoms predisposes to stroke in the general elderly population have been contradictory. Moreover, they did not distinguish between men and women and did not perform psychiatric workups in those with depressive symptoms. This study examines the association between depressive symptoms, depressive disorder and the risk of stroke in the general population. METHODS: This prospective population based cohort study included 4424 participants from the third Rotterdam Study Survey (1997-1999) who, at that time, were > or =61 years of age and free from stroke. Depressive symptoms were assessed using the Centre for Epidemiological Studies Depression Scale (CESD) and considered present if the CESD score was > or =16. Participants with depressive symptoms had a diagnostic interview for depressive disorder. Follow-up was complete until 1 January 2005. Data were analysed using Cox proportional hazards models with adjustment for relevant confounders. RESULTS: Men with depressive symptoms (n = 73) were at increased risk of stroke (adjusted hazard ratio (HR) 2.17; 95% CI 1.11 to 4.23) and ischaemic stroke (adjusted HR 3.21; 95% CI 1.62 to 6.38). These associations were at least partly attributable to men who reported depressive symptoms but who did not fulfil Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV diagnostic criteria for depressive disorder (n = 32): they had a very high risk of stroke (adjusted HR 2.70; 95% CI 1.15 to 6.33) and ischaemic stroke (adjusted HR 4.01; 95% CI 1.68 to 9.57). In women there was no association between presence of depressive symptoms and risk of stroke. CONCLUSIONS: Presence of depressive symptoms is a strong risk factor for stroke in men but not in women.

- BACKGROUND: Low levels of cerebrospinal fluid (CSF) beta-amyloid 1-42 (Abeta42) and high total tau (T-tau) are diagnostic for manifest Alzheimer's disease. It is not known, however, whether these biomarkers may be risk indicators for cognitive decline in otherwise healthy older people. METHODS: The longitudinal relationship between CSF markers, Abeta42 and T-tau, measured in 1992, and change in Mini-Mental State Examination (deltaMMSE) score between 1992 and 2002 were investigated in 55 women (aged 70-84 years, mean (SD) MMSE score = 28.3 (1.5)), who were participants in the Prospective Population Study of Women in Gothenburg, Sweden. These women did not have dementia when they experienced lumbar puncture in 1992-3. RESULTS: Over the 8-year follow-up period, deltaMMSE (range = +3 to -21 points) was correlated with Abeta42 (Spearman's r = 0.40, p = 0.002), such that lower levels of Abeta42 were related to greater decline. This was also observed after excluding 4 women who developed dementia between 1992 and 2002 (Spearman's r = 0.34, p = 0.019). A multivariate logistic regression model predicting a decline of > or = 5 points on the MMSE (observed in six women), or a risk of developing dementia over the 8-year follow-up period (observed in four women), including age, education, Abeta42 and T-tau as covariates, showed that Abeta42 was the sole predictor of significant cognitive decline or dementia (OR per 100 pg/ml Abeta42 = 2.24, 95% CI 1.19 to 4.22, p = 0.013). CONCLUSIONS: Low levels of CSF Abeta42 may predict cognitive decline among older women without dementia.

- AIM: To evaluate the results of ventral intermediate (Vim) thalamic deep brain stimulation (DBS) in patients with tremor predominant Parkinson's disease (PD) at 6 years post surgery.METHODS: This was a prolonged follow-up study of 38 patients from eight centres who participated in a multicentre study, the 1 year results of which have been published previously. Total scores as well as scores for individual items of the motor part and the disability part of the Unified Parkinson's Disease Rating Scale were used for evaluation.RESULTS: Tremor was still effectively controlled by DBS and appendicular rigidity and akinesia remained stable compared with baseline. Axial scores (speech, gait and postural instability), however, worsened, and in parallel the initial improvement in activities of daily living scores at the 1 year follow-up had disappeared at 6 years, despite sustained improvement of tremor. Remarkably, neither daily doses of dopaminergic medication nor fluctuations and dyskinesias had changed at 6 years compared with baseline in this particular patient group.CONCLUSION: This study confirms that patients with tremor dominant PD who do not present with fluctuations and dyskinesias may have a relatively benign progression of the disease. Vim DBS, although having no effect on akinesia and rigidity, is a relatively lenient surgical procedure and may still have a place for long term symptomatic control of PD tremor in selected patients.

- OBJECTIVES: The aim of this study was to prospectively study perioperative variables associated with revision after shunt surgery for adult hydrocephalus. METHODS: Two protocols were designed to prospectively study perioperative risk factors during shunt insertion. Over 10 years (1995-2004), 450 adult (age >16 years) patients with first time shunt implantations were studied. Patients who had been treated with endoscopic third ventriculostomy were excluded from the study. All shunts were designated as meeting one of two end points: (1) shunt failure requiring revision within 6 months or (2) no shunt failure within 6 months. Shunt revision within 6 months postoperatively was considered to be related to the shunting procedure. RESULTS: 85 shunt revisions were performed within 6 months after insertion. During the study period the revision rate declined from 21.1% to 9.1%. Revision rates were the same for ventriculoperitoneal (n = 411) and ventriculoatrial (n = 39) shunts. The predictive values of variables related to the patient, operating room, surgical technique and shunt system were analysed to determine shunt outcome. CONCLUSIONS: Right frontal placement of the ventricular catheter was associated with the lowest rate of revisions. Adjustable valves were associated with a lower risk for shunt revision. Shunt revision rates did not differ between ventriculoperitoneal and ventriculoatrial shunts.

- Objective: To assess overall resource consumption, work capacity and quality of life of patients with multiple sclerosis in nine European countries. Methods: Information on resource consumption related to multiple sclerosis, informal care by relatives, productivity losses and overall quality of life (utility) was collected with a standardised pre-tested questionnaire from 13186 patients enrolled in national multiple sclerosis societies or followed up in neurology clinics. Information on disease included disease duration, self-assessed disease severity and relapses. Mean annual costs per patient (Euro, 2005) were estimated from the societal perspective. Results: The mean age ranged from 45.1 to 53.4 years, and all levels of disease severity were represented. Between 16% and 29% of patients reported experiencing a relapse in the 3 months preceding data collection. The proportion of patients in early retirement because of multiple sclerosis ranged from 33% to 45%. The use of direct medical resources (eg, hospitalisation, consultations and drugs) varied considerably across countries, whereas the use of non-medical resources (eg, walking sticks, wheel chairs, modifications to house and car) and services (eg, home care and transportation) was comparable. Informal care use was highly correlated with disease severity, but was further influenced by healthcare systems and family structure. All types of costs increased with worsening disease. The total mean annual costs per patient (adjusted for gross domestic product purchasing power) were estimated at Euro 18000 for mild disease (Expanded Disability Status Scale (EDSS) < 4.0), Euro 36500 for moderate disease (EDSS 4.0-6.5) and Euro 62000 for severe disease (EDSS > 7.0). Utility was similar across countries at around 0.70 for a patient with an EDSS of 2.0 and around 0.45 for a patient with an EDSS of 6.5. Intangible costs were estimated at around Euro 13000 per patient.

- OBJECTIVE: To compare long term (10 years) seizure outcome, psychosocial outcome and use of antiepileptic drugs (AED) with the 2 year follow-up in adults after resective epilepsy surgery. METHODS: All adults (n = 70) who underwent resective epilepsy surgery from 1987 to 1995 in the Goteborg Epilepsy Surgery Series were included. Fifty-four had undergone temporal lobe resections and 16 extratemporal resections (12 frontal). A cross-sectional follow-up in the form of a semistructured interview was performed in late 2003. RESULTS: Mean follow-up was 12.4 years (range 8.6-16.2). Of the 70 patients (51% males), five (7%) were dead (three as a result of non-epilepsy related causes). Of the 65 patients interviewed, 38 (58%) were seizure-free at the long term follow-up: 65% of the patients with temporal lobe resections and 36% of the patients with extratemporal resections. Of the 35 patients who were seizure-free at the 2 year follow-up, 3 (9%) had seizures at the long term follow-up. Of the 30 patients who had seizures at the 2 year follow-up, 6 (20%) were seizure-free at the long term follow-up. Of all 65 patients, 45 (69%) had the same seizure status as the 2 year follow-up. Sixteen (25%) had an improved seizure status and 4 (6%) had a worsened status. Of the seizure-free patients, 11 (29%) had ceased taking AED, 28 (74%) were working and 25 (66%) had a driving license. CONCLUSIONS: Adult patients who are seizure-free 2 years after resective epilepsy surgery are most likely to still be seizure-free 10 years later. Most are working and have obtained a driving license.

- OBJECTIVES: In cerebral small vessel disease, white-matter hyperintensities (WMH) and lacunes are both related to cognition. Still, their respective contribution in older people remains unclear. The purpose of this study is to assess the topographic distribution of lacunes and determine whether it has an impact on cognitive functions in a sample of non-disabled patients with age-related white-matter changes. METHODS: Data were drawn from the baseline evaluation of the LADIS (Leucoaraioisis and Disability study) cohort of non-disabled subjects beyond 65 years of age. The neuropsychological evaluation was based on the Mini Mental Status Examination (MMSE), a modified Alzheimer Diseases Assessment Scale for global cognitive functions, and compound Z scores for memory, executive functions, speed and motor control. WMH were rated according to the Fazekas scale; the number of lacunes was assessed in the following areas: lobar white matter, putamen/pallidum, thalamus, caudate nucleus, internal/external capsule, infratentorial areas. An analysis of covariance was performed after adjustment for possible confounders. RESULTS: Among 633 subjects, 47% had at least one lacune (31% at least one within basal ganglia). The presence of lacunes in the thalamus was associated with lower scores of MMSE (beta = -0.61; p = 0.043), and worse compound scores for speed and motor control (beta = -0.25; p = 0.006), executive functions (beta = -0.19; p = 0.022) independently of the cognitive impact of WMH. There was also a significant negative association between the presence of lacunes in putamen/pallidum and the memory compound Z score (beta = -0.13; p = 0.038). By contrast, no significant negative association was found between cognitive parameters and the presence of lacunes in internal capsule, lobar white matter and caudate nucleus. CONCLUSION: In non-disabled elderly subjects with leucoaraisosis, the location of lacunes within subcortical grey matter is a determinant of cognitive impairment, independently of the extent of WMH.
