Alcoholism, or Alcohol Use Disorder (AUD), is characterized by physical, emotional, and behavioral symptoms. Individuals may develop increased tolerance, requiring more alcohol to achieve the same effects, and experience withdrawal symptoms like tremors and nausea when they stop drinking. Drinking patterns often become excessive, leading to relationship and work problems. Cognitive impairments such as memory lapses and poor judgment are common, along with physical health issues like liver damage and sleep disturbances. Diagnosing AUD involves a thorough evaluation of symptoms and history by a mental health professional using tools like the DSM-5 criteria. Assessment tools such as the Michigan Alcoholism Screening Test (MAST) help quantify severity. A physical examination may rule out other health issues, while laboratory tests assess alcohol's impact on health. Accurate diagnosis is crucial for effective treatment, which may include therapy and medication. Individuals may face financial and social consequences due to their drinking habits. As AUD progresses, intense cravings can lead to relapse and worsening symptoms.
