Alcohol acts as a sedative on the Central Nervous System, depressing the nerve cells in the brain, dulling, altering and damaging their ability to respond. Large doses cause sleep, anesthesia, respiratory failure, coma and death.
Long term drinking may result in permanent brain damage, serious mental disorders and addiction to alcohol.
Steady drinking over many years leads to permanent changes in the brain. One of the permanent effects of alcohol on the brain is to reduce the amount of brain tissue and to increase the size of the ventricles instead. Another way in which alcoholic drinks affect the brain is through depriving it of food substances such as vitamins. This is because heavy drinkers often neglect their diet, which can lead to vitamin deficiencies. Thiamine, one of the 'B' vitamins is most commonly missing from the diet and can lead to serious mental disturbance.
