Drinking large amounts of alcohol for many years will take its toll on many of the body's organs and may cause organ damage. Organs known to be damaged by long-term alcohol misuse include the brain and nervous system, heart, liver and pancreas.

Often, it's packaged as a neat factoid like “Three beers kill 10,000 brain cells.” But is this true? No. But alcohol does damage some of your 86 billion brain cells, or neurons, which send electrical and chemical messages within the brain and between it and other parts of the body.

Alcohol, which is consumed in beverages such as liquor, wine and beer, is a chemical called ethanol. Ethanol may cause headaches by several means. First, it is a direct vasodilator; in some individuals vasodilation may cause a headache.

The main parts of the brain involved in language processes are the Broca's area, located in the left frontal lobe, which is responsible for speech production and articulation, and the Wernicke's area, in the left temporal lobe, associated with language development and comprehension.

Long-term memory loss Alcohol can destroy nerve cells. This affects a person's memory in the short and long term. In addition, people who drink too much alcohol are often deficient in vitamin B-1, or thiamine. This vitamin is vital to providing energy to brain and nerve cells.

Drinking alcohol in excess kills brain cells. Reality: Even in heavy drinkers, alcohol consumption doesn't kill brain cells. It does, however, damage the ends of neurons, called dendrites, which makes it difficult for neurons to relay messages to one another.

Alcohol in Your Body Alcohol reaches your brain in only five minutes, with immediate effects appearing within 10 minutes. After 20 minutes, your liver begins processing the alcohol. On average, the liver can metabolize 1 ounce of alcohol every hour.

The largest part of the brain, the cerebrum has two hemispheres (or halves). The cerebrum controls voluntary movement, speech, intelligence, memory, emotion, and sensory processing.

The damaged areas of the brain include the hippocampus, which is an area of the brain that helps new memories form. Damage to the frontal lobe of the brain eventually causes problems with intelligence, judgment, and behaviour. Damage to the temporal lobe affects memory. And damage to the parietal lobe affects language.

Alcohol is a CNS depressant, so it can act on similar areas of the brain as other depressant substances. Consuming alcohol in moderation can lead to some desired side effects, including relaxation, lowered inhibitions, decreased anxiety, and greater sociability.

Alcohol use at any level, however, is also bad news for the brain. Even moderate users or those who have been drinking in excess for a short period of time can experience mental fog, anxiety, and mood changes.

The short-term effects of alcohol (more specifically ethanol) consumption – due to drinking beer, wine, distilled spirits or other alcoholic beverages – range from a decrease in anxiety and motor skills and euphoria at lower doses to intoxication (drunkenness), stupor, unconsciousness, anterograde amnesia (memory " ...

So, these three parts of the brain- the amygdala, the hippocampus, and the prefrontal cortex- are the most-affected areas of the brain from trauma. They can make a trauma survivor constantly fearful, especially when triggered by events and situations that remind them of their past trauma.
