Major Depression and Substance Abuse
Major depression and substance abuse often coexist. Many people who suffer from depression turn to drugs or alcohol in an effort to self-medicate. Substance abuse can also directly effect parts of the brain that are responsible for mood. Studies show that over thirty percent of people who suffer from depression have also suffered from some type of substance abuse.
- Alcohol reduces serotonin and norepinephrine levels in the brain, which can lead to or worsen depression.
- Some drugs can activate a gene that is linked to depression.
- Substance abuse increases the risk of suicide.
