What are the 3 most common mental illnesses?

The most common are anxiety disorders major depression and bipolar disorder.

Five major mental illnesses — autism, attention deficit-hyperactivity disorder, bipolar disorder, major depressive disorder and schizophrenia — appear to share some common genetic risk factors, according to an examination of genetic data from more than 60,000 people worldwide (The Lancet, online Feb. 28).

Depression. Impacting an estimated 300 million people, depression is the most-common mental disorder and generally affects women more often than men.

Some common ones include: Anxiety disorders, including panic disorder, obsessive-compulsive disorder, and phobias. Depression, bipolar disorder, and other mood disorders. Eating disorders.

Depression is among the most treatable of mental disorders. Between 80% and 90% percent of people with depression eventually respond well to treatment.

Schizophrenia and personality disorders are the most disabling mental health conditions to live with, according to Queensland Brain Institute's Professor John McGrath.

Mental health disorders including depression, schizophrenia, and anorexia show links to biological markers detected in routine blood tests, according to our new study of genetic, biochemical and psychiatric data from almost a million people.

SMI includes major depression, schizophrenia, bipolar disorder, obsessive compulsive disorder (OCD), panic disorder, post traumatic stress (PTSD) and borderline personality disorder (VA).

What is the least common mental disorder?

Factitious disorder tends to affect less than 0.5% of the population. Also known as 'imposter syndrome' or Capgras Delusion. People with this mental health condition believe that someone in their life that plays a significant role what been replaced with an imposter.

Mental disorders are the result of both genetic and environmental factors. There is no single genetic switch that when flipped causes a mental disorder. Consequently, it is difficult for doctors to determine a person's risk of inheriting a mental disorder or passing on the disorder to their children.

The exact causes of schizophrenia are unknown. Research suggests a combination of physical, genetic, psychological and environmental factors can make a person more likely to develop the condition. Some people may be prone to schizophrenia, and a stressful or emotional life event might trigger a psychotic episode.

Technically, according to DSM-5*, a person can receive more than one personality disorder diagnosis. People who are diagnosed with a personality disorder most often qualify for more than one diagnosis. A person with a severe personality disorder might meet the criteria for four, five or even more disorders!

Anxiety disorder is the most treatable of all mental illnesses. Anxiety disorder produces unrealistic fears, excessive worry, flashbacks from past trauma leading to easy startling, changes in sleep patterns, intense tension and ritualistic behavior.

Panic Disorder. Panic disorder is an anxiety disorder and is characterized by unexpected and repeated episodes of intense fear accompanied by physical symptoms that may include chest pain, heart palpitations, shortness of breath, dizziness, or abdominal distress.

What mental illnesses require medication?

antidepressant medications (treat depression and long-term anxiety) antipsychotic medications (for psychotic symptoms like hallucinations and delusions) mood stabilizers (help bipolar disorder, schizoaffective disorder, and severe symptoms of some personality disorders)

Mental illnesses that can be covered by Social Security disability include depression, anxiety and anxiety-related disorders, autism, ADHD, learning disabilities, and intellectual disability.

A medical professional determines a diagnosis by interviewing you about your history of symptoms. Sometimes a doctor will require a couple of medical tests to rule out possible physical ailments, but we cannot evaluate mental health itself through blood tests or other biometric data.

There isn't a single test that can determine if you have a mental illness—or deem you 100% mentally healthy. Instead, a diagnosis of mental illness is made by a medical or mental health professional who has conducted a thorough evaluation.

A PET scan can compare brain activity during periods of depression (left) with normal brain activity (right). An increase of blue and green colors, along with decreased white and yellow areas, shows decreased brain activity due to depression.

According to the World Health Organization, people with severe mental health disorders have a 10–25-year reduction in life expectancy. Schizophrenia mortality rates are between 2 and 2.5 times those in the general population, while individuals with depression have a 1.8 times higher risk of premature mortality.

Do mental health issues get worse with age? Mental illness isn't a natural part of aging. In fact, mental health disorders affect younger adults more often than the elderly, according to the National Institute of Mental Health. However, seniors are less likely to seek help.

Why is mental health important for overall health? Mental and physical health are equally important components of overall health. For example, depression increases the risk for many types of physical health problems, particularly long-lasting conditions like diabetes, heart disease, and stroke.

Living in a stressful environment can make you more likely to develop a mental illness. Things like living in poverty or having an abusive family put a lot of stress on your brain and often trigger mental illness.
