What can alcohol abuse do to the brain? Alcohol is an irritant to all body tissue, from where it comes in to where it goes out. Alcohol does kill brain cells. Some of those cells can be regenerated over time.
Despite alcohol causing brain damage, it does not kill our brain cells. It does however damage the ends of neurons called dendrites, making it hard for neurons to relay messages to one another.
Brain Fact: Moderate alcohol use doesn't kill brain cells, and while rampant alcohol use can damage the brain, it's not due to cell death. Does alcohol kill brain cells? You've probably heard this myth, but it's not really true. Moderate alcohol intake doesn't kill brain cells, or even damage them.
If a person regularly drinks too much alcohol it can be toxic to their nerve cells. Over time, drinking too much alcohol can cause brain cells to die and a person's brain tissue to shrink. This means there are fewer cells to carry the messages that the brain needs to do different tasks.
Specifically, alcohol disrupts neural stem cell growth and division. Alcohol causes cells to progress more slowly through the cell cycle. The cycle consists of 4 major stages, during which cells grow and produce new proteins (G1), synthesize DNA (S), produce new organelles (G2) and divide by mitosis (M).
Alcohol is an irritant to all body tissue, from where it comes in to where it goes out. Alcohol does kill brain cells. Some of those cells can be regenerated over time. In the meantime, the existing nerve cells branch out to compensate for the lost functions.
Over time, excessive alcohol use can lead to the development of chronic diseases and other serious problems including: High blood pressure, heart disease, stroke, liver disease, and digestive problems.
Drinking higher levels of alcohol and binge drinking are both linked to a lower IQ, research finds. People with higher IQs tend to avoid binge drinking. The conclusions come from a study of 49,321 Swedish men conscripted for military service between 1969 and 1971.
Physical damage to the brain and the spinal cord can also kill or disable neurons. Damage to the brain caused by shaking or hitting the head, or because of a stroke, can kill neurons immediately or slowly, starving them of the oxygen and nutrients they need to survive.
For men, binge drinking is 5 or more drinks consumed on one occasion. Underage drinking: Any alcohol use by those under age 21. Heavy drinking: For women, heavy drinking is 8 drinks or more per week. For men, heavy drinking is 15 drinks or more per week.
Once an alcoholic has stopped drinking, these cells return to their normal volume, showing that some alcohol-related brain damage is reversible. "We found evidence for a rather rapid recovery of the brain from alcohol induced volume loss within the initial 14 days of abstinence," said Ende.
Overall, when consumed regularly in high quantities, alcohol ages the body faster than natural processes allow.
Science has since discovered that neurons can actually regenerate using a really unique method if an area of the brain gets damaged – we call this method neurogenesis. What happens is the brain uses a secret supply of neural stem cells and transforms them into new neurons without using mitosis.
Alcohol Misuse and Its Lasting Effects
Over time, excessive drinking can lead to mental health problems, such as depression and anxiety. Alcohol abuse can increase your risk for some cancers as well as severe, and potentially permanent, brain damage.
Alcohol primarily disrupts the ability to form new long–term memories; it causes less disruption of recall of previously established long–term memories or of the ability to keep new information active in short–term memory for a few seconds or more.
It has long been known that excessive alcohol consumption has a negative impact on vitamin D status. Chronic alcoholism results in disturbed vitamin D metabolism and chronic alcoholics usually have low levels of serum 25-hydroxyvitamin D [25(OH)D] [1,2].
And one of the most exciting and important recent discoveries is that brain cells DO regenerate throughout your entire life. We now know that neurogenesis — the formation of new brain cells — is not only possible, it happens every day. This is not simply a fascinating piece of information, it's news you can use.
Engaging both your body and mind allows you to keep producing new brain cells throughout your life. You can increase neurogenesis through individual lifestyle choices like exercising, eating certain foods, and more. Neuroscientists believed intermittent fasting could be beneficial in enhancing human brain health.
Heavy alcohol consumption has been associated with brain atrophy, neuronal loss, and poorer white matter fiber integrity. However, there is conflicting evidence on whether light-to-moderate alcohol consumption shows similar negative associations with brain structure.
People with high IQs drink more alcohol, although they are unlikely to be heavy drinkers, research finds. In other words, they drink more, on average, but spread it out, and are unlikely to be alcoholics. The results fit with the fact that highly intelligent people are also more likely to use drugs.
Generally, people drink to either increase positive emotions or decrease negative ones. This results in all drinking motives falling into one of four categories: enhancement (because it's exciting), coping (to forget about my worries), social (to celebrate), and conformity (to fit in).
Red wine is widely recognized as one of the healthiest alcoholic drinks out there. Poon notes that it's "relatively low in calories and also offers some health benefits."9 She adds that red wine is rich in antioxidants such as resveratrol and proanthocyanidins and can promote cardiovascular health.
If you stop drinking completely, one of the first things you notice should be improved energy levels, better sleep and finding it easier to wake up in the morning. Regular drinking can affect the quality of your sleep making you feel tired and sluggish during the day.
