Current understanding of brain plasticity has lead to new approaches in ischemic stroke rehabilitation. Stroke units that combine good medical and nursing care with task-oriented intense training in an environment that provides confidence, stimulation and motivation significantly improve outcome. Repetitive trans-cranial magnetic stimulation (rTMS), and trans-cranial direct current stimulation (tDCS) are applied in rehabilitation of motor function. The long-term effect, optimal way of stimulation and possibly efficacy in cognitive rehabilitation need evaluation. Methods based on multisensory integration of motor, cognitive, and perceptual processes including action observation, mental training, and virtual reality are being tested. Different approaches of intensive aphasia training are described. Recent data on intensive melodic intonation therapy indicate that even patients with very severe non-fluent aphasia can regain speech through homotopic white matter tract plasticity. Music therapy is applied in motor and cognitive rehabilitation. To avoid the confounding effect of spontaneous improvement, most trials are preformed >/=3 months post stroke. Randomized controlled trials starting earlier after strokes are needed. More attention should be given to stroke heterogeneity, cognitive rehabilitation, and social adjustment and to genetic differences, including the role of BDNF polymorphism in brain plasticity.

Acta Neurol Scand: DOI: 10.1111/j.1600-0404.2010.01478.x. © 2011 John Wiley & Sons A/S. Objectives - Many severe strokes are preceded by warning signs such as a transient ischemic attack or stroke with minor deficits. Carotid endarterectomy (CEA) of a symptomatic carotid artery stenosis can prevent future strokes, but should be performed within 2 weeks after the initial symptom to maximize the benefit. The aim of this study was to determine the time delays between symptom and CEA. Methods- We performed a single center observational retrospective study at a tertiary stroke center. A total of 142 carotids in 139 patients with symptomatic stenoses between 2002 and 2006 were included. The main outcome measure was time between qualifying cerebrovascular symptom and CEA. Results - The median time between symptom and CEA was 26 days. The longest delays were between the last diagnostic examination and carotid conference, and between carotid conference and surgery. The median time was shorter for those who received emergency medical care (median 21 days) and for those who were admitted immediately to hospital (median 20 days). Conclusions - The time between symptom and surgery is often longer than desirable. There are several measures to improve the chain of procedures for patients with carotid artery stenosis. These may include omitting the formal carotid conference for uncomplicated cases and minimizing waiting time for surgery.

Acta Neurol Scand: DOI: 10.1111/j.1600-0404.2011.01517.x. © 2011 John Wiley & Sons A/S. Background - Parkinson's disease (PD) is a chronic neurodegenerative disease expected to cause great costs. The aim of this study was to calculate drug and treatment costs in patients with PD in Sweden. Method - All healthcare contacts of patients with PD in Stockholm County, Sweden, were extracted from registers together with information on reimbursements from the authorities to the caregivers. PD-related costs were calculated together with non-PD-related costs. Cost per patient was calculated and extrapolated to the whole Swedish population, taking population demographics into consideration. In addition, nationwide PD drug sales statistics were included. Results - The PD prevalence of Stockholm County was estimated to 196 per 100,000 inhabitants, resulting in an estimated total of about 22,000 patients with PD in Sweden. The cost per patient was estimated to SEK 76,000 of which drug costs accounted for SEK 15,880. The annual direct costs in patients with PD in Sweden were SEK 1.7 billion in 2009. Conclusion - Our study estimates high direct costs in patients with PD in Sweden, SEK 1.7 billion, 52% for inpatient care, 27% for outpatient care and 21% for drugs. With an ageing population and the medical progress, the financial burden on society will most probably increase in the future. This study might initiate and provide information for discussions about future cost allocations and healthcare priorities.

(c) 2009 The Authors Journal compilation (c) 2009 Blackwell Munksgaard.Objectives - To evaluate the association between the hyperdense middle cerebral artery sign (HMCAS) and the functional outcome on one hand, and different predictors such as the National Institutes of Health Stroke Scale (NIHSS), infarct size, ASPECTS Score, intracerebral hemorrhage, and mortality on the other hand. Material and methods - Retrospective analysis of 120 patients with MCA-stroke treated with intravenous thrombolysis. We tested the association between HMCAS and NIHSS, infarct volume, ASPECTS, outcome, level of consciousness, different recorded time intervals, and the day/time of admission. Results - Seventy-four percentage of patients treated with thrombolysis developed cerebral infarction. All patients with HMCAS (n = 39) sustained infarction and only 31% showed favorable outcome compared with 62% and 60%, respectively among patients without HMCAS (P < 0.001 and P = 0.002). There was statistically significant association between functional outcome and HMCAS (P = 0.002), infarct volume, NIHSS, and ASPECTS (P < 0.001). The time to treatment was 12 min shorter in patients who developed infarction (P = 0.037). Independent predictors for outcome were NIHSS and the occurrence of cerebral infarction on computed tomography for the whole study population, and infarct volume for patients who sustained cerebral infarction. Conclusions - Despite optimal workflow, patients with HMCAS showed poor outcome after intravenous thrombolysis. The results emphasize the urgent need for more effective revascularization therapies and neuroprotective treatment in this subgroup of stroke patients.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background/aim - There are several reports that claim anticipation in complex or polygenic diseases such as multiple sclerosis (MS), Crohn disease or schizophrenia. The aim of the present study was to assess age at onset of MS during the last 60 years in the region of Costa de Ponent (Barcelona, Spain) showing how apparent changes in age at onset between generations can be an artefact of analysis based on cohorts that have not been followed enough time. Methods - The study comprised 1100 patients diagnosed of MS. The method used to correct for follow-up time bias involves constructing comparison cohorts that had been observed for the same amount of time. To ensure equal follow-up times, we restricted our analysis to patients whose onset was by 37 years of age (percentile 75) and were at least 37 years old. We analysed differences in age at onset using log-rank test to compare survival curves estimated by Kaplan-Meier method. Results - Age at onset decreases progressively from older to younger generations. However, when adjustment to equal follow-up time was done, anticipation in age at onset was not found. Conclusion - Anticipation of age at onset is undetectable when adjusted for follow-up time.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVE: To test the hypothesis that cerebrospinal fluid (CSF)/ serum albumin ratios are increased in violent offenders. SUBJECTS AND METHODS: In a previous study of violent offenders, we found significantly higher CSF/serum album ratios (as a sign of increased blood-brain barrier permeability) in violent offenders than in healthy controls. For the present replication study, we recruited a new group of 28 violent offenders, aged 45 years or younger, and 20 new control subjects. RESULTS: The albumin ratio was again significantly higher in the offender group (mean 6.2) than in the control group (mean 4.6) (P = 0.012). Substance abuse or current medication did not appear to explain this finding. CONCLUSION: Increased CSF/serum albumin ratios are an unspecific sign of neurological dysfunction in subgroups of violent offenders.

- OBJECTIVE: To study changes in cerebrospinal fluid (CSF) protein markers of blood-CSF barrier integrity and immunological reactions during surgical stress. SUBJECTS AND METHODS: Thirty-five patients without neurological or psychiatric disorders undergoing knee replacements had CSF and serum samples drawn from spinal and arterial catheters before, 3 h after and the morning after surgery. RESULTS: Serum albumin decreased during surgery and CSF albumin decreased during and after surgery, and, as a consequence, the CSF/serum albumin ratio decreased significantly during the study period, especially after the intervention. In contrast, CSF concentrations of beta-2-microglobuline (beta2M) increased significantly during surgery and remained high. The CSF general marker beta-trace protein (betaTP) remained unchanged. CONCLUSIONS: Central nervous system protein reactions to a non-neurological surgical intervention include sharply decreased permeability of albumin into the CSF and signs of intrathecal inflammatory activity.
