definition of mental illness

Mental illness refers to health conditions that affect a person’s thoughts, feelings, emotions, or behaviors, leading to difficulties in daily life. These conditions are health issues of the brain, similar to how physical illnesses affect body organs. Mental illnesses are common, and they can result from a combination of genetic, biological, environmental, and psychological factors. They are treatable through therapy, medication, or support, and seeking help can lead to better well-being and improved functioning. Recognizing mental illness as a health condition helps reduce stigma and encourages those affected to get appropriate care.
