Study Notes
Actions/Effects of Alcohol
- Inhibits impulsivity and judgment, leading to impaired decision-making
- Disrupts communication between brain cells, causing impaired coordination and balance
- Enhances the effects of GABA (inhibitory neurotransmitter), leading to relaxation and sedation
Symptoms of Alcohol Consumption
- Slurred speech and impaired motor skills ( Blood Alcohol Content (BAC) > 0.08%)
- Drowsiness, confusion, and decreased response to stimuli (BAC > 0.15%)
- Loss of consciousness and suppressed breathing (BAC > 0.30%)
Effects of Alcohol on the Nervous System
- Depresses the central nervous system, slowing down neural activity
- Impairs cognitive function, memory, and learning
- Interferes with the brain's reward system, leading to addiction
Cardiovascular Effects of Alcohol
- Low to moderate consumption (1-2 drinks/day) reduces cardiovascular disease risk
- High consumption (>3 drinks/day) increases blood pressure, heart rate, and cardiovascular disease risk
- Binge drinking increases risk of cardiac arrhythmias and sudden death
Chronic Effects of Alcohol
- Liver damage and cirrhosis due to chronic heavy drinking
- Increased risk of certain cancers, such as liver, breast, and colon cancer
- Nutritional deficiencies, particularly thiamine deficiency (Wernicke-Korsakoff syndrome)

Description
This quiz covers the pharmacology of alcohol, focusing on its mechanism of action. It explores how alcohol acts as a CNS depressant and the acute effects it causes by enhancing the effect of GABA and inhibiting glutamate action on NMDA receptors.
