How Alcohol Disrupts the Brain: A Complex Balance of Stimulation and Suppression
Alcohol consumption affects brain function by simultaneously slowing key processes and triggering euphoric neurotransmitter releases.
- Alcohol reaches the brain within six minutes of consumption, impacting both cognitive and physical functions.
- It slows cellular communication and energy production, impairing reaction times, vision, and situational awareness.
- Excessive drinking can lead to memory blackouts, or 'filmrisse,' where short-term memories fail to transfer into long-term storage.
- Alcohol’s dual effects—dampening most brain activity while stimulating some regions—create a state of imbalance likened to pressing the gas and brake pedals simultaneously.
- Hangovers result from factors like dehydration, disrupted sleep, and toxic byproducts of alcohol metabolism, including acetaldehyde and methanol derivatives.
