What do delerium tremens do to your brain?

DTs. Depends on the severity as it can cause mild damage to death. If you have had this disorder then you should be under careful observation and medical care. Develop a healthy life style and do not drink any amount of alcohol.
Fries it kinda. By the time people have been drinking long and hard enough to get dts, they have already done significant brain damage, losing literally hundreds of billions of brain cells. Dt;s doesnt improve things, and it has a significant mortality as well. Seizures do even more damage, and many people with dts get them right after one or more seizures. If this is you, please get help. Aa, alanon, your doctor.
