[Extrapyramidal disorders in chronic cerebral vascular insufficiency (clinico-morphologic study)]

Area of Science:

• Neurology
• Vascular Medicine
• Clinical Research

Context:

• Chronic cerebral circulation insufficiency is often caused by hypertensive disease or atherosclerosis.
• Extrapyramidal disorders can manifest in patients with these conditions.
• Understanding the vascular origins of these disorders is crucial for diagnosis and treatment.

Purpose:

• To classify and describe extrapyramidal disorders of vascular genesis in patients with chronic cerebral circulation insufficiency.
• To investigate the relationship between specific vascular lesions and the development of distinct neurological syndromes.
• To correlate the occurrence of these syndromes with the underlying cause (hypertension or atherosclerosis) and its severity.

Summary:

• Six distinct extrapyramidal syndromes were identified in 190 patients with chronic cerebral circulation insufficiency: extrapyramidal-pyramidal, extrapyramidal-pseudobulbar, extrapyramidal-cerebellar, extrapyramidal-thalamic, extrapyramidal-spinal, and arteriosclerotic muscular rigidity.
• These syndromes can arise from lesions in the striate arteries, stenosing atherosclerosis of carotid arteries, or involvement of the vertebrobasilar system vessels.
• The specific syndrome observed depends on the location and extent of vascular damage and the characteristics of the primary disease.

Impact:

• Provides a classification of vascular-related extrapyramidal disorders.
• Highlights the diverse vascular origins of these neurological deficits.
• Aids in understanding the complex interplay between cerebrovascular disease and movement disorders.
