[Morphology of the brain and heart in alcoholic psychoses]
Insights
Chronic alcoholism causes brain and heart damage, leading to a harmful cycle of worsening neurological and cardiac conditions. This study highlights the interconnectedness of these alcohol-induced pathologies.
Area of Science:
- Neurology
- Cardiology
- Pathology
Context:
- Focuses on the effects of chronic alcoholism on the brain and heart.
- Examines patients diagnosed with alcoholic delirium, Wernicke's encephalopathy, and acute alcoholic intoxication.
- Investigates morphological alterations in brain and heart tissues.
Purpose:
- To investigate the morphological changes in the brain and heart associated with chronic alcoholism.
- To define the observed disorders as an exacerbation of chronic alcoholic encephalopathy and cardiomyodystrophy.
- To elucidate the pathological mechanism involving a vicious circle of cardiac and cerebral dysfunction.
Summary:
- Studied 40 patients with chronic alcoholism, observing compromised vascular permeability, neuronal and cardiomyocyte damage, microgliocyte proliferation, and cardiosclerosis.
- Identified these changes as an exacerbation of alcoholic encephalopathy and cardiomyodystrophy.
- Proposed that alcoholic heart damage disrupts cerebral hemodynamics, causing hypoxia and impaired central cardiac regulation, perpetuating brain damage.
Impact:
- Highlights the detrimental impact of chronic alcoholism on both neurological and cardiovascular systems.
- Suggests a cyclical pathological process where heart damage exacerbates brain dysfunction and vice versa.
- Provides insights into the pathophysiology of severe alcohol-related organ damage.
Abstract:
The authors studied the brain and heart of 40 patients (30 males and 10 females) who were hospitalized with the clinical diagnosis of alcoholic delirium, Gaye-Wernike's encephalopathy, and acute alcoholic intoxication due to chronic alcoholism. The morphological alterations in the brain and heart were as follows: compromised vascular permeability, dystrophic changes in the neurons and cardiomyocytes, proliferative reaction of microgliocytes and the development of small cardiosclerosis. Such disorders can be defined as an exacerbation of chronic alcoholic encephalopathy and cardiomyodystrophy. Alcoholic damage to the heart seems to be one of the additional factors that disrupt cerebral hemodynamics which results in hypoxia of the cerebral tissue and is accompanied by impairment of the central regulation of cardiac activity and progression of cerebral changes, i. e. the pathological process develops according to the vicious circle principle.
