Who gets mental health disorders?

Having a mental illness is not something to be ashamed of and is common around the world. Nearly 1 in 5 adults in the United States have a mental illness. An estimated 1 in 6 American children aged 6 to 17 have a mental illness.^2,3

What causes mental health conditions?

Mental illness is not the result of a single event. Doctors believe genes, environment, and lifestyle interact with life events to cause a mental health condition to develop. A stressful job may be a contributing factor for some, while trauma might be for others. Not all people who have such events or situations develop mental illness. If you do have a mental health condition, you are not “broken” and have not done anything wrong.^2,3

Common mental health conditions

Depression

Depression may also be called major depressive disorder. Depression is more than feeling “blue” or simply sad. Depression is a serious medical condition that affects how you feel, act, and think. Symptoms vary widely and may include low moods, feelings of worthlessness, and hopelessness in an episode that lasts longer than 2 weeks. Sleep problems are common in those with depression.⁴

Generalized anxiety disorder (GAD) is anxiety or worry about multiple things, most days, for at least 6 months. Fear and anxiety can cause major problems in life, including social situations, school, and work.⁵

Panic disorder

Panic disorder is a type of anxiety disorder in which a person has panic attacks. Panic attacks are brief episodes of intense fear. These may happen right after a certain event or situation makes you feel especially stressed. Sometimes it seems to happen at random.⁵

The physical symptoms of a panic attack can include:⁵

• Pounding heart
• Sweating
• Difficulty breathing

Obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) is a condition in which people perform repetitive behaviors (compulsions). They may also have constant and uncontrollable thoughts or urges (obsessions).⁶

Eating disorders

Schizophrenia spectrum and other psychotic disorders

People with schizophrenia spectrum disorders and other psychotic disorders cannot distinguish between reality and their hallucinations and delusions. Hallucinations are when someone sees, hears, smells, tastes, or feels things that do not exist outside their mind. A delusion happens when a person has an unshakeable belief in something untrue.^8,9

Bipolar disorder

Bipolar disorder (type 1 or 2) involves an extreme fluctuation between moods. These episodes may last at least several days, with the person moving between elevated or depressed moods. The elevated moods are called mania. Mania can make a person very active and cause them to feel elated or “high.” It can also cause someone to become more irritable or engage in risky behaviors.^10,11

Post-traumatic stress disorder

Post-traumatic stress disorder (PTSD) may develop following a shocking, scary, or dangerous event or series of events. PTSD may cause severe impairment, recurrent thoughts of the trauma, flashbacks, nightmares, and difficulty performing daily tasks.¹²

Sleep disorders

Sleep and mental health are closely linked. Problems with the quality and amount of sleep are more likely in people living with mental health disorders. And, sleep disorders like insomnia increase the risk of depression, anxiety, and problems focusing or making decisions.¹³

Substance use disorder

Substance use disorder is dependence or addiction to specific substances, such as alcohol or drugs. It often co-occurs with other mental health conditions. Substance use disorder should be treated at the same time as any other mental health issues.¹⁴

Personality disorders

People with personality disorders have emotions and behaviors that depart from social norms. Their emotions and behaviors tend to be inflexible and unable to respond to life’s demands. These disorders cause issues in relationships and other important areas of life.^15,16

Chronic illness and depression

Rates of depression are much higher in people with chronic illness than in the general population. The reasons for this may include:¹⁷
