Why Should You Abstain from Drinking Alcohol After a TBI?

Alcohol abuse brings down the brain’s recovery speed. Thus, abstaining from drinking is a much-needed reprieve that a TBI patient can give to his brain, giving it a chance to heal and fix the damage.

TBI patients are in danger of developing epileptic seizures. Drinking can trigger such seizures, risking the survivors another brain injury. A TBI incident can also elevate the chances of suffering from another brain trauma. Alcohol, which takes a severe toll on balance and coordination, can make such probabilities come true.

Drinking exacerbates cognitive problems like lack of versatility in thinking and poor memory, which are both caused by TBI. Such cognitive impairments brought about by alcohol can last for days to several weeks post-consumption. Staying away from that peg of drink can keep your cognition razor sharp.

Depression is something that TBI survivors experience within a year of the accident.
