In psychology, a disorder is a condition that affects a person’s thinking, feeling, or behavior such that someone’s daily life is significantly disturbed or affected by distress. Disorders aren’t passing struggles or everyday challenges; they are persistent patterns and often hinder someone’s ability to function in work, school or relationships.
Mental disorders can be very extensive, such as anxiety disorders, mood disorders such as depression, or even more complex disorders such as schizophrenia. They are typically diagnosed according to recognized criteria, such as those described in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5-TR). While the causes of disorders can vary, they are often a combination of biological, genetic, and environmental factors. Diagnosis and treatment of disorders are important for guiding interventions that will promote well-being and quality of life.
