Atrophy of the cerebellum

Atrophy of the cerebellum is observed in a number of cases after suffering meningitis, as a result of atherosclerosis, almost all pathological processes developing within the posterior cranial fossa and demarcates its space (extra - and intracerebral tumors, cysts). Secondary cross-atrophy cerebellar hemisphere observed in the defeat of the opposite hemispheres with hemiplegia in cases where the disease has developed in utero or at an early age. The clinical picture hemiplegia dims cerebellar symptoms. Chronic degeneration cerebellar systems, when there are no meningeal-vascular changes are manifested in the form of various forms of the disease, among which we should dwell on Olivo-Ponto-cerebellar atrophy (atrophia olivo-ponto-cerebellaris).
Postmortem this form is characterized by simultaneous rebirth lower olive, nuclei bridge, cerebellar cortex and the death of relevant conductive systems. The etiology of the disease is not clear. The clinical picture at the forefront are the progressive disorders of the statics and walking, infringement of coordination of movements of legs, disertacija disorders, eye, a swallowing disorder, in some cases, incontinence, mental disorders and signs of akinetic-rigid syndromic. The disease often begins at the age of 45-55 years old and slow progress for 6-10 years; patients usually die from accidental infectious diseases on the background of severe brain damage.
