Summary
Alcoholism significantly impairs postural balance, even in individuals not actively drinking. This study highlights the lasting effects of alcohol on the nervous system and body control.
Area of Science:
- Neuroscience
- Human Physiology
Background:
- Alcoholism is a chronic condition characterized by intoxication and symptoms like gait instability and dizziness.
- Postural balance is crucial for daily activities and can be affected by various neurological conditions.
Purpose of the Study:
- To investigate the impact of alcoholism on postural balance.
- To differentiate balance deficits in alcoholic individuals compared to a non-alcoholic control group.
Main Methods:
- Prospective study involving 32 alcoholic individuals and 32 non-alcoholic controls.
- Evaluations included otorhinolaryngological assessment, static and dynamic balance tests, cerebellar tests, and vecto-electro-nystagmography (VENG).
- Dynamic posturography was employed to assess postural control.
Main Results:
- VECTO-ELECTRO-NYSTAGMOGRAPHY (VENG) results were largely normal, suggesting intact labyrinth and oculomotor-vestibular pathways.
- Balance disorders in alcoholics likely originate from other central or peripheral nervous system dysfunctions.
- Dynamic posturography revealed significant postural balance alterations in non-drinking alcoholics compared to controls.
Conclusions:
- Alcohol consumption has a detrimental effect on body balance.
- Balance impairments in alcoholism may stem from neurological dysfunctions beyond the vestibular system.

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about the way you...
01:27CNS Depressants: Alcohol and Nicotine
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...
