The usefulness of diffusion-weighted/fluid-attenuated inversion recovery imaging in the diagnostics and timing of lacunar and nonlacunar stroke.

Introduction: The DWI/FLAIR mismatch is a potential radiological marker for the timing of stroke onset. The aim of the study was to assess if the DWI/FLAIR mismatch can help to identify patients with both lacunar and nonlacunar acute ischemic stroke within 4.5 h of onset.

MRI brain findings in ephedrone encephalopathy associated with manganese abuse: Single-center perspective.

Background: Manganese (Mn) is a well-known toxic agent causing symptoms of parkinsonism in employees of certain branches of industry. Home production of a psychostimulant ephedrone (methcathinone), involving the use of potassium permanganate, became a new cause of intoxications in Poland.

Case Report: This article presents clinical symptoms, initial brain MRI findings and characteristics of changes observed in follow-up examinations in 4 patients with manganese intoxication associated with intravenous administration of ephedrone.

[Encephalopathy caused by intravenous potassium permanganate used for illegal production of methcathinone (ephedrone) from medicines containing pseudoephedrine].

Encephalopathy caused by manganese compounds used for illicit production of ephedrone (methcathinone) is described. The onset of disease could be observed after some months of regular intravenous use of ephedrone contaminated with manganese. In clinical picture dominate neurological signs and symptoms, mainly extrapyramidal syndromes: parkinsonism, tremor, muscle distonia, pro- and retropulsion.

Training in rapid auditory processing ameliorates auditory comprehension in aphasic patients: a randomized controlled pilot study.

Experimental studies have often reported close associations between rapid auditory processing and language competency. The present study was aimed at improving auditory comprehension in aphasic patients following specific training in the perception of temporal order (TO) of events. We tested 18 aphasic patients showing both comprehension and TO perception deficits.

Correlations between cerebellar and brain volumes, cognitive impairments, ApoE levels, and APOE genotypes in patients with AD and MCI.

Due to the increasing incidence of Alzheimer's disease (AD), many studies have aimed to improve its diagnosis. Particular attention has been focused on measuring volumes of brain structures. Only few studies have investigated whether the cerebellar volume changes with the stage of dementia.
