[Indicators of cognitive impairment of varying severity in the acute period of ischemic stroke].

Objective: To assess phenotype and identify biomarkers of cognitive impairment (CI) of varying severity in patients in the acute period of ischemic stroke (IS) based on the analysis of clinical and paraclinical indicators.

Material And Methods: Two hundred and forty patients with diagnosed IS and presence of CI were examined. Depending on the scores on the Montreal Cognitive Assessment Scale, patients were divided into two groups: group 1 (=182) with mild CI, group 2 (=58) with dementia.

[Neuropathy in n-hexane poisoning].

N-Hexane is a solvent widely used in manufacturing as a cleaner, degreaser and component of rubber cement. Chronic exposure to -hexane either through contact with unprotected skin or inhalation can lead to the development of clinical symptoms and electrophysiological changes similar to those of inflammatory demyelinating polyneuropathy which requires careful differential diagnosis. This article presents three cases of severe predominantly motor polyneuropathy with demyelinating features in 15- and 16-year-old adolescents.
