• Disorders of thinking and memory: Alcohol can damage areas of the brain that are responsible for memory (such as hippocampus), leading to short-term memory loss (power outages) or difficulty in long-term thinking if you consume it excessively over time.
• Contraction of brain tissue: Prolonged alcohol consumption can lead to brain atrophy (shrinkage of brain tissue), which can affect the areas responsible for movement, balance, memory and learning.
• Neurotoxicity: Chronic alcohol consumption has neurotoxic effectswhich can lead to damage and even death of nerve cells in the brain, contributing to decreased thinking ability and health conditions that involve progressive damage to these cells.
• Alcohol withdrawal: When you stop drinking alcohol, your nervous system, which has adapted to the presence of alcohol, can become hyperactive, challenging withdrawal symptoms such as anxiety, tremors, seizures and hallucinations.
