Guest Post: Does Traumatic Brain Injury Increase The Risk Of Substance Abuse By Matt Gonzales

It is well established that substance abuse could lead to traumatic brain injuries. According to a study published in the Journal of Head Trauma Rehabilitation, 60 percent of 211 TBI injuries involved drugs or alcohol.

But can a brain injury lead to substance abuse? According to a report published by the U.S. National Library of Medicine, it is possible.

The study suggests people who experience a TBI have shown a preference for small, immediate rewards over larger, delayed rewards — similar to individuals with a substance use disorder. It suggests TBI may impair their ability to understand the consequences of drug use.

There are more reasons as to why people with brain injuries turn to drugs or alcohol:

  • Depression
  • Isolation
  • Self-medication due to chronic pain

NFL players know what chronic pain feels like. This has led to substance abuse among many players.

In a study published by Drug and Alcohol Dependence 52 percent of 644 retired NFL players admitted to using prescription pain medications during their playing days. Of that group, 71 percent admitted to misusing drugs. Many continued using into retirement.

Another study published by the U.S. National Library of Medicine reported that individuals who sustained a TBI prior to 5 years old or between ages 16 and 25 were at an increased risk for drug or alcohol dependence.

Additional risk factors for substance abuse after TBI:

  • Pre-TBI substance abuse
  • Post-TBI depression
  • Male
  • Young adult
  • Unmarried
  • Lack of health insurance

After a traumatic injury, a person’s brain is more vulnerable to drugs and alcohol. Small amounts of alcohol, for instance, may affect a person’s judgement or their ability to walk. Substance abuse among TBI survivors also increases the chance of sustaining another brain injury.

There are many ways to address a substance abuse problem. One effective route is to seek treatment. If you or someone you know has picked up a drug or alcohol dependence after a brain injury, contact a nearby treatment center.
