The brain naturally produces steroids, which are used in normal brain functions and regulation. Anabolic steroids, however, are manufactured chemicals that are taken orally or through an injection. This type of steroid resembles testosterone and increases a person's muscle size; anabolic steroids are also the type of steroid that causes side effects in the brain. Some of the side effects, especially those caused by abnormal hormone levels, are irreversible, according to the National Institute on Drug Abuse (NIDA).
Emotional Changes
When a person uses anabolic steroids, the chemicals interfere in the normal function of the limbic system, which is located in the temporal lobe in the brain. Part of the limbic system is the amygdala, which is involved in emotional behavior. NIDA notes that synthetic steroids cause aggressive behavior, which is colloquially referred to as "roid rage." The Connecticut Clearinghouse adds that anabolic steroid users are prone to mood swings, violent behavior and psychotic symptoms, which include hallucinations and delusions.
Impaired Thinking
The hippocampus, which is responsible for converting short-term memories into long-term memories, is also part of the limbic system and is affected by anabolic steroid use. People who use steroids experience problems with learning and memory. Users also have impaired judgment.
Hypothalamus Interference
Another area of the brain affected by anabolic steroid use is the hypothalamus, which is another part of the limbic system. The hypothalamus is the "regulator" in the brain, and maintains normal function in the brain. One side effect of steroid use is disrupted hormone levels. NIDA states that men who use steroids have abnormal testosterone production, which results in smaller testes and hair loss; female users experience no period, scalp hair loss, deeper voice, and increased body and facial hair. The hair and voice changes are irreversible.
