[Clinical-neuropsychological study of patients with hematomas, cavernomas and arteriovenous malformations of the brain stem].
A clinical-neuropsychological study of 25 patients with hematomas, cavernomas and arteriovenous malformations of different brain stem regions has been performed. Patients with hydrocephalic-hypertensive and dislocation syndromes as well as a history of neurological diseases were excluded from the study. All patients had hemorrhages in different brain stem regions, most of which had occurred several weeks ago. Hematomas were located in different regions of the pons (14 patients) and midbrain (7 patients) and spread to both regions in 4 patients. All patients underwent MRI study of the brain and complex neuropsychological investigation using the A.R. Luria's method. Neuropsychological symptoms before the surgery were found in 20 patients. Cognitive disturbances similar by the lesion of frontal lobes, in particular the promoter zone, that manifested themselves in disturbances of dynamic praxis, writing, verbal memory, were observed most often. Cognitive disturbances similar by the lesion of occipital hemisphere regions, i.e. disturbances of visual gnosis and spatial defects, were found less often. The most severe symptoms were observed in the lesion of the midbrain and upper regions of the pons.
