- <i>Background:</i> Lowering of blood pressure (BP) in the acute phase of stroke is reported both to worsen and to improve the outcome. To investigate whether heterogeneity exists between stroke subtypes in the response to BP lowering, we analysed data from the Intravenous Nimodipine West European Stroke Trial (INWEST). <i>Methods:</i> INWEST enrolled acute ischaemic stroke patients within 24 h (n = 295) to the following groups: placebo (n = 100), 1 mg/h nimodipine (n = 101) or 2 mg/h nimodipine (n = 94). Patients were retrospectively classified as total anterior circulation infarct (TACI) (i.e. hemiparesis + hemianopia + dysphasia) and non-TACI (exclusion of any one of these). Main outcome measures were neurological (Orgogozo) and functional (Barthel) scores at day 21. <i>Results:</i> 106 patients were labelled as TACI and 62 as non-TACI. No significant difference in BP was observed between the TACI and non-TACI subtypes at baseline, nor did the subtypes differ in BP course within the treatment groups. A higher proportion of non-TACI patients received postrandomisation antihypertensive agents in addition to the study drug compared with TACI patients (55% non-TACI vs. 26% TACI, p < 0.005). For TACI patients, there was no outcome difference between the placebo- and nimodipine-treated groups. For non-TACI patients, placebo had a significantly better neurological (p = 0.004) and functional (p = 0.04) outcome than the high-dose nimodipine group. In multivariate analysis for TACI patients, BP reduction and nimodipine treatment had no relation with outcome. Baseline stroke severity (p < 0.005) was the only significant predictor of the outcome at day 21. For non-TACI patients, diastolic BP (DBP) reduction (p = 0.03) and nimodipine treatment (p = 0.001) were related to neurological deterioration and nimodipine treatment (p = 0.01) to functional deterioration. Systolic BP reduction was associated with neurological (p < 0.005) and functional improvement (p = 0.01). Baseline stroke severity (p < 0.005) was related to both neurological and functional outcome. <i>Conclusion:</i> BP lowering and nimodipine treatment had no significant effect on outcome for TACI patients. For non-TACI patients, DBP lowering worsened the neurological outcome and high-dose nimodipine worsened both the neurological and functional outcome.

- <i>Background/Aim:</i> The cause of elevated blood pressure (BP) in acute stroke is unknown. Stress is often suggested as a main contributing factor. We aimed to investigate the relationship between BP and stress in patients with acute stroke. <i>Methods:</i> 58 patients with clinical symptoms of stroke were recruited prospectively after exclusion of haemorrhage by CT scan within 14 h and 15 min (mean) after symptom onset (range 2 h and 45 min–23 h and 40 min). The mean age of the patients was 66 years (range 39–86 years), and the mean National Institute of Health Stroke Scale score was 7 (range 1–26). BP and pulse rate were recorded by non-invasive automatic monitoring hourly for 24 h. Stress was evaluated by testing the level of salivary cortisol. Four samples of saliva were obtained at inclusion, on the evening of the inclusion day (20.00–22.00 h), on the morning of the next day (7.00–9.00 h) and on the afternoon of the inclusion day/next day (15.00–17.00 h) within 24 h after inclusion in the study. Logarithmic transformation was done for cortisol levels. <i>Results:</i> The 24-hour mean cortisol level (geometric mean 13.6 nmol/l) was related to 24-hour mean systolic BP [SBP; r = 0.36, p = 0.01, multivariate p = 0.02], mean night-time (22.00–6.00 h) SBP (r = 0.43, p = 0.001, multivariate p < 0.005) and mean night-time diastolic BP (r = 0.31, p = 0.02, multivariate p = 0.02). Cortisol levels at inclusion (r = 0.31, p = 0.02, multivariate p = 0.05 for 24-hour SBP) and in the evening were also statistically significantly related to the above BP variables. The morning cortisol (r = 0.28, p = 0.04, multivariate p = 0.04) was related to night-time SBP. <i>Conclusions:</i> Salivary cortisol was positively correlated with 24-hour SBP and night-time BP, suggesting that stress is a contributing factor for high BP in acute stroke.

- BACKGROUND AND PURPOSE: Mild strokes can be neglected regarding subtle sequels as fatigue, and cognitive and emotional changes. We have addressed this topic by exploring late consequences of an initially mild stroke (Barthel score >or=50). Accordingly, we assayed impairment, disability and handicap data 1 year after the first-ever stroke in persons <75 years, focusing on symptoms as fatigue, concentration difficulties, memory disturbances, emotional lability, stress resistance, anxiety and uneasiness, symptoms comprised in the astheno-emotional disorder (AED), and its relation to life satisfaction. RESULTS: The mean value of the Barthel Index was 99.5 (SD 0.5) and 25% scored 0-1 on the Oxford Handicap Scale. AED was diagnosed in 71% of the patients, and fatigue was experienced by 72%. AED correlated significantly with life satisfaction, handicap and depression. Life satisfaction was significantly below that of norm values according to satisfaction with life as a whole, sex life and ability to manage selfcare. CONCLUSIONS: Our findings emphasize that 'hidden dysfunctions' not so easily discovered within the hospital context are common consequences of mild stroke. The concept of mild stroke as principally founded in motor function or ability in P-ADL therefore seems to be insufficient with respect to the patient long-term perspective.

- The white matter is an important locus for tissue damage in vascular cognitive impairment and white matter lesions often dominate over gray matter changes. The spectrum of ischemic white matter lesions histopathologically represents focal and diffuse lesions, the most common form being the combination of both, in varying proportions. In the combined pathology, the diffuse lesion represents a gradient zone of damage towards surrounding normal tissue and may hold over 200 times the volume of an identified focal lesion, the lacunar infarct. Pathogenetically, the focal lesion results from the acute reaction to regional ischemia, while the diffuse white matter lesion represents the adjustment to altered perfusional and physiological conditions within the tissue.

- <i>Background:</i> Many studies have reported lower mortality in married people. The relation between marital status and incidence of haemorrhagic and ischaemic stroke is unclear. It is largely unknown whether the risk of stroke is increased the first years after divorce or death of spouse. <i>Methods:</i> Incidence of first-ever stroke (n = 6,184) was followed over 10 years in a cohort consisting of all 40- to 89-year-old inhabitants (n = 118,134) in the city of Malmö, Sweden. Marital dissolution (i.e. divorce or death of spouse) prior to the date of stroke was compared in a nested case-control design (3,134 initially married stroke cases, 9,402 initially married controls). <i>Results:</i> As compared to the married groups, the incidence of stroke was increased in divorced men and women (RR = 1.23, CI: 1.10–1.39 and RR = 1.26, CI: 1.12–1.41, respectively) and widowed men and women (RR = 1.13, CI: 0.99–1.28 and RR = 1.13, CI: 1.02–1.24, respectively) after adjustments for age, country of birth and socioeconomic indicators. The risk of stroke was not increased in never married men. Marital dissolution was followed by increased risk of stroke, which was significant for men (adjusted odds ratio: 1.23, CI: 1.03–1.5) and borderline significant for women below 65 years of age (odds ratio: 1.45, CI: 0.99–2.14). <i>Conclusion:</i> The incidence of stroke is increased in divorced and widowed individuals. Never married men do not have an increased incidence. The risk of stroke is elevated during the first years after divorce or death of spouse.

- In this study, 339 patients (154 men, 185 women) with a median age of 74 years (range 23-97) admitted to the Stroke Unit, Department of Neurology in 1986, have been followed up for 14 years. The diagnoses were intra-cerebral hemorrhage (ICH, 30, 8.8%), cardioembolic cerebral infarction (CE, 71, 20.9%), lacunar infarction (LI, 47, 13.9%) and atherosclerotic cerebral infarction (ACI, 191, 56.3%). The cumulative probabilities of recurrent stroke rates at 1-, 5- and 10-year follow-ups were 13.5% (95% confidence interval, CI, 9.6-17.4), 38.7% (95% CI 32.6-44.8) and 53.9% (95% CI 46.7-61.1). According to Cox proportional hazard regression analysis, age, severity of stroke, previous stroke and systolic blood pressure are each of importance in predicting recurrent stroke. During the observation period, 290 patients (85.5%) died. The mortality rate of 24.5% during the first year was 4.5 times higher compared to the normal population of the same age and gender. Patients with LI had lower mortality rates compared to ICH by the log rank test (p =0.0275), to CE (p =0.000) and to ACI (p =0.049). Thirty-nine percent of all vascular deaths after the first year were caused by recurrent strokes. Fatal index/recurrent stroke occurred statistically more frequently in the CE group versus the non-CE one (p =0.005). Cox proportional hazard regression analysis indicated that age, severity of stroke, previous stroke, heart failure and fasting blood glucose exceeding 6 mmol/l or history of diabetes were each predictors of mortality. In conclusion, this study has shown the worse outcomes for all subtypes of stroke compared to the normal population and also clearly pointed out independent predictors of recurrent stroke or death at the time of diagnosis.

- Rating scales play an important role in the evaluation of computed tomography (CT) or magnetic resonance-detected white matter lesions (WML). Unfortunately, this type of visual semiquantitative assessment is not yet an optimal tool because commonly agreed concepts regarding its use are lacking. To generate a discussion platform for further improvement of CT and MRI rating, we will provide some basic definitions, summarize the advantages and disadvantages of scoring schemes and review current efforts towards the improvement of this tool. Future research will have to concentrate on deepening our understanding of the histopathologic substrates of WML and on strategies to document their progression.

- A new sample of 116 stroke patients was collected in order to validate a logistic regression model, predicting the chances of severely affected stroke patients being discharged home to independent living. The model was found to be accurate in the new sample, especially for those patients who had a high estimated probability of being discharged home. When the dividing line for the predicted probability for discharge home was set at a value of >/=0.5, the positive and negative predictive values were 74 and 73%, respectively. Further modelling resulted in a new extended model including the variables postural stability on admission, cohabiting, age and perceptual impairment on admission that formed the basis for an index predicting discharge home. This index was then validated in the sample of 93 patients that the first developed model was derived from and showed positive and negative predictive values of 85 and 77%, respectively
