Summary
This study measured cerebral white matter water content in alcoholics and controls. Results confirm increased water content in alcoholics, refuting hydration changes as the cause of brain shrinkage.
Area of Science:
- Neuroscience
- Biochemistry
Background:
- Alcoholism is associated with brain shrinkage.
- The cause of this shrinkage, specifically the role of hydration, remains debated.
Purpose of the Study:
- To investigate the water content of cerebral white matter in individuals with alcoholism.
- To determine if hydration status changes contribute to alcohol-related brain shrinkage.
Main Methods:
- Quantitative measurement of water content in cerebral white matter.
- Comparison between a group of 24 individuals with alcoholism and 26 control subjects.
Main Results:
- A statistically significant increase in cerebral white matter water content was observed in the alcoholic group compared to controls.
- Findings align with previous in vivo Magnetic Resonance Imaging (MRI) and necropsy studies.
Conclusions:
- The observed increase in brain water content in alcoholics is confirmed.
- This finding refutes the hypothesis that altered hydration states are the primary cause of reversible brain shrinkage in alcoholism.
