Psychological disorders, also referred to as mental disorders or mental illnesses, are conditions that disrupt an individual's thoughts, emotions, behaviors, and overall mental well-being. These disorders can vary widely in terms of symptoms, severity, and duration. They encompass a broad spectrum of conditions, including mood disorders like depression and bipolar disorder, anxiety disorders such as generalized anxiety disorder and obsessive-compulsive disorder, psychotic disorders like schizophrenia, and trauma-related disorders like post-traumatic stress disorder (PTSD). Additionally, there are eating disorders, personality disorders, and substance use disorders, among others.

Psychological disorders can result from a combination of genetic, biological, environmental, and psychological factors. They often lead to significant distress, impaired functioning, and reduced quality of life for affected individuals. Proper diagnosis and treatment are crucial, and therapeutic approaches may include psychotherapy, medication, lifestyle changes, and support from mental health professionals. Timely intervention and understanding of these disorders are essential for individuals to lead fulfilling lives and manage their mental health effectively.
