It is a myth that drinking kills brain cells. Instead, alcohol damages the brain in other ways, for instance, by damaging the ends of neurons. This can make it difficult for those neurons to send important nerve signals. Alcohol may also damage the brain by increasing the risk of strokes, head injuries, and accidents.
Does alcohol affect the neurons?
Alcohol acts as a general depressant of the central nervous system. It “depresses” or inhibits the function of neurons by reducing their ability to transmit or “fire” electrical impulses.
Does drinking alcohol actually kill brain cells?

What does ethanol do to neurons?
At the cellular level, ethanol induces activation of inflammatory and degenerative processes in the brain [88, 89]. Ethanol affects neuronal communication by altering the synthesis, release, and signaling of neurotransmitters , including glutamate, dopamine, and GABA [88, 90, 91].
What does alcohol do to nerves?
Excessive drinking over a prolonged period of time can cause serious problems with cognition and memory. Alcohol interacts with the brain receptors, interfering with the communication between nerve cells, and suppressing excitatory nerve pathway activity.
Does alcohol make you permanently dumber?

What kills your brain cells the most?
Concussions, contusions, and even head banging can lead to the loss of large quantities of neurons. Amphetamine abuse, antipsychotics, benzodiazepine abuse, cigarettes and tobacco products, cocaine, ecstasy, inhalants, and methamphetamines can all negatively impact the brain and cause the death of its cells.
How do you know if you have brain damage from alcohol?
