Mental Disorders

A mental disorder or mental illness refers to a psychological pattern, often manifested in behavior, that typically involves distress or impairment and is not considered a normal part of a person's cultural development. Mental disorders are typically characterized by a combination of feelings, behaviors, thoughts, or perceptions, often influenced by specific brain regions or functions within the nervous system, and may occur within a social context.

The recognition and understanding of mental health conditions have evolved over time and across cultures, leading to variations in definition, assessment, and classification. However, standardized guideline criteria are widely utilized. According to the World Health Organization (WHO), a significant proportion of individuals in most countries experience issues at some point in their lives that meet the diagnostic criteria for one or more common types of mental disorder.

The causes of mental disorders are diverse and, in some instances, unclear, with theories drawing from various fields. Mental health services are provided in psychiatric hospitals or community settings, with assessments conducted by psychiatrists, clinical psychologists, and clinical social workers using diverse methods, often relying on observation and inquiry. Clinical treatments are delivered by various mental health professionals.

Psychotherapy and psychiatric medication are primary treatment options, complemented by social interventions, peer support, and self-help. In some cases, involuntary detention or treatment may occur where permitted by law. Stigma and discrimination can exacerbate the suffering and disability associated with mental disorders, leading to social movements aimed at fostering understanding and combating social exclusion. Prevention strategies are increasingly integrated into mental health approaches.

Mental disorders encompass a broad spectrum of conditions, including anxiety disorders (such as panic disorder, obsessive-compulsive disorder, post-traumatic stress disorder, and phobias), bipolar disorder, depression, personality disorders, and psychotic disorders (including schizophrenia).

Multiple factors contribute to mental disorders, including genetic predisposition and family history, life experiences such as stress or past trauma, and biological influences. Traumatic brain injuries or maternal exposure to viruses or toxins during pregnancy may also contribute. Other risk factors include substance abuse and certain medical conditions like cancer.

Many mental disorders can be managed with medications and counseling.
