One thought on “What biological factors increase the risk of addiction?

  1. Arti says:

    Scientists estimate that genes, including the effects environmental factors have on a fewone’s gene expression, called epigenetics, account for between 40 and 60 percent of a fewone’s risk of addiction. Drug use and mental illness often co-exist. But with continued use, a fewone’s ability to exert self-control can become seriously impaired; this impairment in self-control is the hallmark of addiction. 27¬†Also, teens and people with mental disorders are at greater risk of drug use and addiction than others. Biological factors that can affect a fewone’s risk of addiction include their genes, stage of development, and even gender or ethnicity. In a few cases, mental disorders which include anxiety, depression, or schizophrenia may come before addiction; in other cases, drug use may trigger or worsen those mental health conditions, particularly in people with specific vulnerabilities. Brain imaging studies of people with addiction show physical changes in areas of the brain that are critical to judgment, decision-making, learning and memory, and behavior control. 12 These changes help explain the compulsive nature of addiction. The initial decision to take drugs is typically voluntary.
