Mental illness worldwide continues to be a problem, and it’s getting worse. Chemical imbalances characterize several types of mental illnesses; however, some affect people physically and emotionally. They can also co-occur with substance abuse and severely disrupt someone’s life. Learn about the five most common types of mental illness, with some co-occurring with each other or other mental illnesses.

 

Depression

Depression continues to be the most common mental disorder with an overwhelming bias towards women. According to The World Health Organization (WHO), it impacts an estimated 260 million people worldwide and one of the leading causes of disability. The symptoms of depression vary in levels of severity, such as a loss of interest and pleasure, feelings of guilt or low self-worth, reduced concentration, tiredness, disturbed sleep or appetite, and sadness. Depending on the severity and type of depression, it can be debilitating to some people.

Also, cognitive-behavioral therapy is an effective form of treatment for moderate to severe depression. However, medication should not be used for children as the first line of treatment. In it’s most severe form, it can lead to suicide. Also, substance use and abuse can make depression worse since alcohol is a natural depressant.

 

Bipolar Disorder

Approximately 45 million people globally have bipolar disorder, which usually consists of both manic and depressive episodes. Normal moods separate these. When in the manic phase, the person can feel unstoppable and invincible. The symptoms can include over-activity, inflated self-esteem, rapid speech, and need for less sleep. Note that people who do not experience depressive episodes can still be classified as having bipolar.

Schizophrenia and Other Psychoses

A severe mental disorder, schizophrenia affects 20 million people worldwide. This psychosis, among others, is characterized by alterations in thinking, perception, emotions, language, and sense of self and behavior. Some of these psychotic experiences include hallucinations (hearing, seeing, feeling things that aren’t there) and delusions (fixed false beliefs or suspicions when there is no evidence for them but are firmly held). The disorder can make it challenging for people to work or study normally. Because of the stigma and discrimination attached to schizophrenia, access to health and social services are reduced.

Development Disorders

They usually present in early childhood but tend to continue into adulthood, which causes delays in central nervous system maturation. There’s usually not periods of remission or relapse, but a steady course.
