Types of Mental Health Conditions

Understanding Mental Health Conditions

Mental health conditions are health conditions involving changes in emotion, thinking, or behaviour (or a combination of these). They are associated with distress and problems functioning in social, work, or family activities. They are common — around 1 in 5 adults in the United States experience a mental health condition in any given year.

Mental health conditions are medical conditions, not character flaws or signs of weakness. Most are treatable, and people can and do recover, manage symptoms, and live fulfilling lives.

Common Mental Health Conditions

Anxiety Disorders

Anxiety disorders are the most common mental health conditions. They include:

• Generalised Anxiety Disorder (GAD) — excessive worry about many things, difficulty controlling the worry, physical symptoms such as tension, fatigue, and sleep problems
• Panic Disorder — recurrent panic attacks (intense surges of fear with physical symptoms) and persistent worry about future attacks
• Social Anxiety Disorder — intense fear of social situations and being judged by others
• Specific Phobias — intense, irrational fear of specific objects or situations
• Agoraphobia — fear of situations where escape might be difficult
• Separation Anxiety Disorder — fear of separation from attachment figures (common in children, also occurs in adults)

Mood Disorders

• Major Depressive Disorder (Depression) — persistent low mood, loss of interest, fatigue, and related symptoms lasting two or more weeks and significantly affecting daily functioning
• Persistent Depressive Disorder (Dysthymia) — a chronic, lower-level form of depression lasting at least 2 years
• Bipolar Disorder — cycling between episodes of depression and mania or hypomania
• Seasonal Affective Disorder (SAD) — depression that follows a seasonal pattern, typically worse in autumn and winter
• Premenstrual Dysphoric Disorder (PMDD) — severe mood symptoms in the week before menstruation

Trauma- and Stressor-Related Disorders

• Post-Traumatic Stress Disorder (PTSD) — re-experiencing, avoidance, negative thoughts and mood, and hyperarousal following a traumatic event
• Acute Stress Disorder — similar to PTSD but occurring in the days immediately after trauma; may resolve or develop into PTSD
• Adjustment Disorder — emotional or behavioural symptoms in response to a stressor, more severe than expected

Obsessive-Compulsive and Related Disorders

• Obsessive-Compulsive Disorder (OCD) — recurrent obsessions and compulsions
• Body Dysmorphic Disorder (BDD) — preoccupation with a perceived flaw in appearance
• Hoarding Disorder — persistent difficulty discarding possessions
• Trichotillomania — recurrent hair-pulling

Psychotic Disorders

• Schizophrenia — a serious condition involving disturbances in thinking, perception, emotions, and behaviour; symptoms include hallucinations (hearing or seeing things that are not there), delusions (fixed false beliefs), and disorganised thinking
• Schizoaffective Disorder — features of both schizophrenia and a mood disorder
• Brief Psychotic Disorder — sudden, short-term onset of psychotic symptoms

Eating Disorders

• Anorexia Nervosa — restriction of food intake, intense fear of weight gain, distorted body image
• Bulimia Nervosa — binge eating followed by compensatory behaviours
• Binge Eating Disorder — recurrent binge eating without compensatory behaviours
• Avoidant/Restrictive Food Intake Disorder (ARFID) — restriction based on sensory sensitivity or fear, not body image

Neurodevelopmental Disorders

• Attention-Deficit/Hyperactivity Disorder (ADHD) — persistent inattention, hyperactivity, and/or impulsivity that interferes with functioning; present from childhood though often diagnosed in adulthood
• Autism Spectrum Disorder (ASD) — differences in social communication, restricted interests, and sensory sensitivities; highly variable presentation

Personality Disorders

Personality disorders involve enduring patterns of inner experience and behaviour that deviate significantly from cultural expectations and cause distress or impairment. They include:

• Borderline Personality Disorder (BPD) — instability in relationships, self-image, and emotions; impulsivity; fear of abandonment; sometimes self-harm
• Narcissistic Personality Disorder — grandiosity, lack of empathy, need for admiration
• Antisocial Personality Disorder — disregard for others' rights, deception, impulsivity
• Avoidant Personality Disorder — extreme sensitivity to criticism, feelings of inadequacy, social inhibition

Substance Use Disorders

Other Conditions

• Dissociative Disorders — disruptions in consciousness, memory, identity, or perception
• Somatic Symptom and Related Disorders — physical symptoms that cause significant distress and are not fully explained by a medical condition
• Sleep-Wake Disorders — including insomnia disorder, sleep apnoea, and narcolepsy
• Disruptive Mood Dysregulation Disorder (DMDD) — severe recurrent temper outbursts in children

Getting Diagnosed

Many people live with a mental health condition for years before receiving a diagnosis. If you are concerned about your mental health, speaking to your doctor is the first step. A thorough assessment may include:

• Medical history and physical examination (to rule out physical causes)
• Psychological evaluation
• Questionnaires or screening tools
• Sometimes referral to a psychiatrist or specialist

A diagnosis does not define you — it is a tool that helps access the right support.

Treatment Works

The vast majority of mental health conditions are treatable. Common treatment approaches include:

• Talking therapies (CBT, DBT, psychodynamic therapy, EMDR)
• Medication (antidepressants, mood stabilisers, antipsychotics, anxiolytics)
• Self-management and lifestyle (exercise, sleep, social connection)
• Peer support and community
• Complementary approaches (mindfulness, yoga, creative therapies)

Treatment is often most effective when several approaches are combined. See our articles on talking therapies and finding help.
