Alcohol dependence, also known as alcoholism, is a chronic and often progressive disorder characterized by a strong craving for alcohol, loss of control over drinking, withdrawal symptoms when not drinking, and tolerance to the effects of alcohol. It is considered a type of substance use disorder and can have serious physical, mental, and social consequences. Research in this area focuses on understanding the causes of alcohol dependence, identifying risk factors, and developing effective prevention and treatment strategies. Studies may explore the genetic, environmental, and psychological factors that contribute to the development of alcohol dependence, as well as the impact of alcohol abuse on the brain and body. Treatment options may include therapy, medications, and support groups to help individuals overcome alcohol dependence and lead a healthier and more fulfilling life.
