Mental Health Conditions

A mental illness is a condition that affects a person's thinking, feeling or mood. Such conditions may affect someone's ability to relate to others and function each day. Each person will have different experiences, even people with the same diagnosis.
Recovery, including meaningful roles in social life, school and work, is possible, especially when you start treatment early and play a strong role in your own recovery process.
A mental health condition isn’t the result of one event. Research suggests multiple overlapping causes. Genetics, environment and lifestyle influence whether someone develops a mental health condition. A stressful job or home life makes some people more susceptible, as do traumatic life events like being the victim of a crime. Biochemical processes and circuits and basic brain structure may play a role, too.

ADHD

Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children. ADHD also affects many adults. Symptoms of ADHD include inattention (not being able to keep focus), hyperactivity (excess movement that is not fitting to the setting) and impulsivity (hasty acts that occur in the moment without thought).

An estimated 8.8% of children aged 4-17 have ADHD. While ADHD is usually diagnosed in childhood, it does not only affect children. An estimated 4.4% of adults aged 18-44 have ADHD. It can also affect adults. It is more common among boys than girls.

Anxiety disorders

Experiencing occasional anxiety is a normal part of life. However, people with anxiety disorders frequently have intense, excessive and persistent worry and fear about everyday situations. Often, anxiety disorders involve repeated episodes of sudden feelings of intense anxiety and fear or terror that reach a peak within minutes (panic attacks).
These feelings of anxiety and panic interfere with daily activities, are difficult to control, are out of proportion to the actual danger and can last a long time. You may avoid places or situations to prevent these feelings. Symptoms may start during childhood or the teen years and continue into adulthood.

Examples of anxiety disorders include generalized anxiety disorder, social anxiety disorder (social phobia), specific phobias and separation anxiety disorder. You can have more than one anxiety disorder. Sometimes anxiety results from a medical condition that needs treatment.

Anxiety disorders are the most common mental health concern in the United States. Over 40 million adults in the U.S. (19.1%) have an anxiety disorder. Meanwhile, approximately 7% of children aged 3-17 experience issues with anxiety each year. Most people develop symptoms before age 21. Whatever form of anxiety you have, treatment can help.

Autism

Autism spectrum disorder (ASD) is a developmental condition that affects a person’s ability to socialize and communicate with others. People with ASD can also present with restricted and/or repetitive patterns of behavior, interests or activities. The term “spectrum” refers to the degree in which the symptoms, behaviors and severity vary within and between individuals. Some people are mildly impaired by their symptoms, while others are severely disabled.

Based on Centers for Disease Control and Prevention (CDC) suveillance, an average of 1 in every 59 8-year-old children in the U.S. have ASD. Boys are four times more likely than girls to develop symptoms of ASD. Children across demographic and socioeconomic groups experience ASD. Awareness and improved screening methods have contributed to the increase in diagnoses in recent years.

Bipolar Disorder

Bipolar disorder is a mental illness that causes dramatic shifts in a person’s mood, energy and ability to think clearly. People with bipolar experience high and low moods—known as mania and depression—which differ from the typical ups-and-downs most people experience.

The average age-of-onset is about 25, but it can occur in the teens, or more uncommonly, in childhood. The condition affects men and women equally, with about 2.8% of U.S. adults experiencing bipolar disorder each year. Approximately 83% of cases of bipolar disorder are classified as "severe".

If left untreated, bipolar disorder usually worsens. However, with a good treatment plan including psychotherapy, medications, a healthy lifestyle, a regular schedule and early identification of symptoms, many people live well with the condition.

Borderline Personality Disorder

Borderline Personality Disorder (BPD) is a condition characterized by difficulties regulating emotion. This means that people who experience BPD feel emotions intensely and for extended periods of time, and it is harder for them to return to a stable baseline after an emotionally triggering event.

This difficulty can lead to impulsivity, poor self-image, stormy relationships and intense emotional responses to stressors. Struggling with self-regulation can also result in dangerous behaviors such as self-harm (e.g. cutting).

It’s estimated that 1.4% of the adult U.S. population experiences BPD. Nearly 75% of people diagnosed with BPD are women. Recent research suggests that men may be equally affected by BPD, but are commonly misdiagnosed with PTSD or depression.

Depression

Depressive disorder, frequently referred to simply as depression, is more than just feeling sad or going through a rough patch. It’s a serious mental health condition that requires understanding and medical care. Left untreated, depression can be devastating for those who have it and their families. Fortunately, with early detection, diagnosis and a treatment plan consisting of medication, psychotherapy and healthy lifestyle choices, many people can and do get better.

Some will only experience one depressive episode in a lifetime, but for most, depressive disorder recurs. Without treatment, episodes may last a few months to several years.

More than 17 million U.S. adults—over 7% of the population—had at least one major depressive episode in the past year. People of all ages and all racial, ethnic and socioeconomic backgrounds experience depression, but it does affect some groups more than others.

Dissociative Disorders

Dissociative disorders are characterized by an involuntary escape from reality characterized by a disconnection between thoughts, identity, consciousness and memory. People from all age groups and racial, ethnic and socioeconomic backgrounds can experience a dissociative disorder.

Up to 75% of people experience at least one depersonalization/derealization episode in their lives, with only 2% meeting the full criteria for chronic episodes. Women are more likely than men to be diagnosed with a dissociative disorder.

The symptoms of a dissociative disorder usually first develop as a response to a traumatic event, such as abuse or military combat, to keep those memories under control. Stressful situations can worsen symptoms and cause problems with functioning in everyday activities. However, the symptoms a person experiences will depend on the type of dissociative disorder that a person has.

Treatment for dissociative disorders often involves psychotherapy and medication. Though finding an effective treatment plan can be difficult, many people are able to live healthy and productive lives.

Early Psychosis and Psychosis

Most people think of psychosis as a break with reality. In a way it is. Psychosis is characterized as disruptions to a person’s thoughts and perceptions that make it difficult for them to recognize what is real and what isn’t. These disruptions are often experienced as seeing, hearing and believing things that aren’t real or having strange, persistent thoughts, behaviors and emotions. While everyone’s experience is different, most people say psychosis is frightening and confusing.

Psychosis is a symptom, not an illness, and it is more common than you may think. In the U.S., approximately 100,000 young people experience psychosis each year. As many as 3 in 100 people will have an episode at some point in their lives.

Early or first-episode psychosis (FEP) refers to when a person first shows signs of beginning to lose contact with reality. Acting quickly to connect a person with the right treatment during early psychosis or FEP can be life-changing and radically alter that person’s future.

Eating Disorders

When you become so preoccupied with food and weight issues that you find it harder and harder to focus on other aspects of your life, it may be an early sign of an eating disorder. Without treatment, eating disorders can take over a person’s life and lead to serious, potentially fatal medical complications.

Eating disorders can affect people of any age or gender, but rates are higher among women. Symptoms commonly appear in adolescence and young adulthood.

Obsessive-Compulsive Disorder

Obsessive-compulsive disorder (OCD) is characterized by repetitive, unwanted, intrusive thoughts (obsessions) and irrational, excessive urges to do certain actions (compulsions). Although people with OCD may know that their thoughts and behavior don't make sense, they are often unable to stop them.

Symptoms typically begin during childhood, the teenage years or young adulthood, although males often develop them at a younger age than females. 1.2% of U.S. adults experience OCD each year.

Posttraumatic Stress Disorder

Traumatic events—such as an accident, assault, military combat or natural disaster—can have lasting effects on a person’s mental health. While many people will have short term responses to life-threatening events, some will develop longer term symptoms that can lead to a diagnosis of Posttraumatic Stress Disorder (PTSD). PTSD symptoms often co-exist with other conditions such as substance use disorders, depression and anxiety. A comprehensive medical evaluation resulting in an individualized treatment plan is optimal.

PTSD affects 3.6% of the U.S. adult population—about 9 million individuals. About 37% of those diagnosed with PTSD are classified as having severe symptoms. Women are significantly more likely to experience PTSD than men.

Schizoaffective Disorder

Schizoaffective disorder is a chronic mental health condition characterized primarily by symptoms of schizophrenia, such as hallucinations or delusions, and symptoms of a mood disorder, such as mania and depression.

Many people with schizoaffective disorder are often incorrectly diagnosed at first with bipolar disorder or schizophrenia. Because schizoaffective disorder is less well-studied than the other two conditions, many interventions are borrowed from their treatment approaches.

Schizoaffective is relatively rare, with a lifetime prevalence of only 0.3%. Men and women experience schizoaffective disorder at the same rate, but men often develop the illness at an earlier age. Schizoaffective disorder can be managed effectively with medication and therapy. Co-occurring substance use disorders are a serious risk and require integrated treatment.

Schizophrenia

Schizophrenia is a serious mental illness that interferes with a person’s ability to think clearly, manage emotions, make decisions and relate to others. It is a complex, long-term medical illness. The exact prevalence of schizophrenia is difficult to measure, but estimates range from 0.25% to 0.64% of U.S. adults.

Although schizophrenia can occur at any age, the average age of onset tends to be in the late teens to the early 20s for men, and the late 20s to early 30s for women. It is uncommon for schizophrenia to be diagnosed in a person younger than 12 or older than 40. It is possible to live well with schizophrenia.
