Why is alcohol considered a downer?
Alcohol is often described as a “downer” because it slows down signals sent between neurons. Additionally, certain automatic brain processes controlled by the cerebellum and cerebral cortex are impaired or slowed (i.e. breathing, balance, processing new information). It also slows GABA neurotransmitters, resulting in slurred speech, lethargic movements, and reduced reaction time. Conversely, alcohol causes the rapid release of glutamate neurotransmitters (responsible for dopamine regulation in the reward center of the brain). This creates the “warm, fuzzy” feelings many associate with drinking.

How Alcohol Causes Brain Damage
Types of Alcohol-Related Brain Damage
- The popular drinking term “wet brain” actually refers to a condition within the alcohol-related brain damage family known as Wernicke-Korsakoff Syndrome (WKS). The disease consists of two separate-but-linked forms of dementia. Those with an alcohol use disorder (AUD) are commonly malnourished due to a poor diet. Often, this leads to a thiamine (or vitamin B1) deficiency becau…
Alcohol-Related Brain Damage Diagnosis
- Generally, an individual will develop alcohol-related brain damage after 10 to 20 years of heavy drinking (though some have developed brain damage in less time). Women may develop alcohol-related brain damage in a shorter time span due to body size. People between the ages of 45 and 60 are the most commonly diagnosed group because it takes time for symptoms to appear. Oft…
Treatment For Alcohol-Related Brain Damage
- Depending on the severity of brain damage, patients may receive either preventative, restorative, or end-of-life supportive medical care. There are no cures for alcohol-related brain damage. For those with WKS, thiamine and vitamin supplements can improve brain function. Early diagnosis of alcohol-related dementia, hepatic encephalopathy, and FAS c...
Mechanism
Clinical significance
- As described in an article from the National Institute on Alcohol Abuse and Alcoholism, this thiamine deficiency can result in brain injury that includes a combination of Wernickes encephalopathy and Korsakoffs psychosis. This debilitating and potentially deadly neurological condition causes nerve paralysis and mental confusion, as well as an inability to coordinate mus…
Mechanism of action
- Stimulants like cocaine and methamphetamine have direct action on dopamine and its receptors in the brain, reducing the uptake of the neurotransmitter, which is the source of the extreme euphoria these drugs can cause. However, another result of this action is that, over time, the dopamine receptor cells in the brain can be damaged or even die off, as described in a study fro…
Prognosis
- Because this is the result of actual cell death, the lack of ability to feel pleasure can last long after use of the drug is stopped. The follow-up result then can be deep depression, including suicidal thoughts and self-destructive actions. However, with treatment and continued abstinence from the substance, dopamine receptors and capabilities can repair and return to some function. Add…
Cause
- While the causes of this condition are not fully understood, there are multiple hypotheses about it, including one that optic nerve damage results in inflammation or that an enzyme that supports visual perception is disrupted. Whatever the case, this condition can persist many years after hallucinogen use is stopped. Hypoxia is often an acute condition brought on by opioid overdose…
Treatment
- Depending on the type of damage, it may be possible to reverse the damage caused by drug or alcohol abuse. By reintroducing missing nutrients or promoting reestablishment of chemical pathways in the brain, early-stage damage can be reversed or at least somewhat repaired. However, in cases of extensive cell death or damage, reversal may not be possi...
