Background and Purpose We sought to determine whether lactate N -acetyl signals measured by proton magnetic resonance spectroscopy (MRS) in the first days after stroke correlate with clinical measures of disability functional outcome. Methods One-dimensional spectroscopic imaging was performed on 32 patients using a 2.1-T magnet. The Toronto Stroke Scale score at time MRS study Barthel Index hospital discharge were determined from patient records. Lesion volume estimated tracing algorithm...

Circumscribed focal atrophy with frontal lobe dementia and progressive aphasia, as described originally by Arnold Pick, has been recognized recently being much more common than previously believed. Although Pick disease became linked argyrophilic inclusions (Pick bodies) swollen neurons cells), the majority of atrophies have findings that are a variation classic histologic features. We discuss Pick's background circumstances led to his major contributions study behavioral neurology. also...

Stroke is a major medical problem and one of the leading causes mortality disability all over in Europe. However, there are significant East–West differences stroke care as well morbidity rates. Central Eastern European countries that formerly had centralized socialist health systems have serious similar problems organizing 20 years after political transition. In Europe, more frequent, rate higher, victims younger than Western High-risk patients live worse environmental conditions,...

BACKGROUND: The aim of this study was to assess the effect anticoagulation treatment on platelet aggregation.METHODS: group consisted 24 patients long-term warfarin therapy without any antiaggregation therapy.Platelet aggregation measured using VerifyNow with arachidonic acid (AA) as an inducer in 23 and light transmission aggregometry (LTA) 19 four different agonists.All had their international normalized ratio (INR) checked regularly.RESULTS: mean INR value 2.07 (SD 0.6).The average by...

Abstract Histological observations, published in 1907-12 by A. Alzheimer and more thoroughly O. Fischer, became source of the assumption that brain amyloid neurofibrillary tangles are causing a specific disease leading to dementia. At time, when research over last 30 years has found large variety processes impair performance aging construct Alzheimer´s (AD) is losing its meaning. The communication among neuroscientists will therefore benefit from shedding dichotomy "healthy "versus" AD"and...

Our understanding of the mental deterioration associated with old-age have undergone a number changes over past two centuries and spurred major scientific debates. In 19th century, this disorder was still considered to be an inevitable feature aging. The dawn 20th century offered histological explanation for presenile dementia, Alois Alzheimer credited as discoverer new disease that bears his name. During last quarter twentieth findings were massively applied also late-onset thus virtually...

The clinical aspects and histopathology of dementia are best understood when based on knowledge the historical milestones associated with its development. We studied archive materials visited some psychiatric asylums that were active in Prague during 19th century. <i>Results:</i> gradual recognition histological correlates territory actual Czech Republic from 1830s described, together links to Austrian, German, other foreign psychiatry neurology.

Abstract A group of 20 persons with cerebral infarctions who had been treated vinpocetine was compared a similar patients other vasoregulative drugs. Two computed tomography (CT) examinations were evaluated for each patient. The initial scan done during the first ten days, and second between 20th 50th day after stroke. Three parameters studied: extension lesion, intensity hypodensity, presence postcontrast enhancement. In criteria, vinpocetine‐treated exhibited better results, whereas third...
