Understanding the Different Categories of Mental Health Conditions
Anxiety disorders are the most common type of mental illness, affecting 40 million adults in the United States alone.

Anxiety disorders include generalized anxiety disorder, panic disorder, agoraphobia, social anxiety disorder, specific phobias, and separation anxiety disorder.
Mood disorders are a group of mental health conditions that affect a person’s emotional state, including their moods and feelings. The two main types of mood disorders are depression and bipolar disorder. Depression is a pervasive feeling of sadness, hopelessness, and worthlessness that lasts for at least two weeks. Bipolar disorder involves periods of extreme highs (mania or hypomania) and lows (depression).
Psychotic disorders are severe mental health conditions that cause a person to lose touch with reality. People with psychotic disorders experience hallucinations, delusions, and disordered thinking. The most well-known psychotic disorder is schizophrenia, but other types include schizoaffective disorder, delusional disorder, and brief psychotic disorder.
Eating disorders are mental illnesses that involve abnormal eating habits and patterns. Eating disorders can cause significant physical and emotional harm and are associated with high mortality rates. The three most common types of eating disorders are anorexia nervosa, bulimia nervosa, and binge eating disorder.
Trauma- and Stressor-Related Disorders
Trauma- and stressor-related disorders are mental health conditions that result from exposure to traumatic or stressful events. Examples of trauma- and stressor-related disorders include posttraumatic stress disorder (PTSD), acute stress disorder, and adjustment disorder.
Substance-Related and Addictive Disorders
Substance-related and addictive disorders are mental illnesses that involve the misuse of drugs, alcohol, or other substances. Substance-related and addictive disorders include alcohol use disorder, opioid use disorder, cocaine use disorder, and gambling disorder.
Personality disorders are mental health
conditions that involve deeply ingrained patterns of thinking, feeling, and behaving that are inflexible and maladaptive. People with personality disorders often struggle with interpersonal relationships and have difficulty functioning in society. Some examples of personality disorders include borderline personality disorder, narcissistic personality disorder, and antisocial personality disorder.
Obsessive-Compulsive and Related Disorders
Obsessive-compulsive and related disorders are mental illnesses that involve obsessive thoughts and compulsive behaviors. People with these disorders often feel compelled to engage in repetitive, ritualistic behaviors or thoughts to alleviate anxiety or distress. Examples of obsessive-compulsive and related disorders include obsessive-compulsive disorder (OCD), body dysmorphic disorder, and hoarding disorder.
Neurodevelopmental disorders are mental health conditions that affect brain development and function. These disorders usually manifest early in life and can impact a person’s ability to learn, communicate, and interact with others. Examples of neurodevelopmental disorders include autism spectrum disorder, attention-deficit/hyperactivity disorder (ADHD), and intellectual disability.
Sleep disorders are mental health conditions that involve disturbances in sleep patterns or behaviors. Sleep disorders can impact a person’s physical and mental health, affecting mood, energy, and overall quality of life. Examples of sleep disorders include insomnia, sleep apnea, and narcolepsy.

People with dissociative disorders may experience amnesia, depersonalization, or derealization, which can cause significant distress and impairment. Examples of dissociative disorders include dissociative identity disorder (formerly known as multiple personality disorder), dissociative amnesia, and depersonalization/derealization disorder.
Sexual dysfunctions are mental health conditions that affect a person’s ability to function sexually. These disorders can involve a wide range of issues, including low libido, premature ejaculation, and erectile dysfunction.
