[Structural alterations in the human brain in chronic alcohol intoxication].
Chronic alcoholism causes significant brain damage, including vascular changes and neurocyte alterations, leading to impaired brain structure and function. These findings aid in the postmortem diagnosis of alcoholism.
Area of Science:
- Neuropathology
- Toxicology
- Forensic Medicine
Context:
- Studied brain samples from 23 male alcoholics and 14 healthy individuals.
- Focused on histological changes and tissue structure in deceased subjects.
Purpose:
- To determine histological changes in the brain due to alcoholism.
- To analyze quantitative relationships between brain tissue structures in alcoholics.
Summary:
- Alcoholics' brains exhibit vascular sclerosis, hyalinosis, and neurocyte damage (dystrophy, atrophy, hypertrophy).
- Observed calcified deposits, cysts, demyelination, and microgliosis, indicating diffuse brain injury.
- Narrowed cerebral capillaries lead to reduced vascular capacity and chronic ischemia.
- Decreased neuron concentration and increased glial component indices were noted.
Impact:
- Findings are crucial for understanding the pathogenesis of alcoholism-related brain damage.
- Contribute to postmortem forensic-medical diagnosis of alcoholism.
