What is mental illness?
Mental illness is a medical condition that is diagnosable and treatable.
Mental illness affects a person’s behavior, emotions or thinking, and is considered serious when it interferes with their ability to function day to day. People with serious mental illness may have difficulty interacting with others, holding a job or coping with adversity or change. In the most severe cases, hospitalization may be necessary.
There are more than 200 classified forms of mental illness that range from mild to severe.
Some of the most common serious mental illnesses are:
Feelings of sadness and/or a loss of interest in activities that were once enjoyed
- Bipolar disorder
Also known as manic-depressive illness, a brain disorder that leads to shifts in mood and activity level, from periods of elation to periods of hopelessness
A severe disorder that can lead to a break with reality, and may include hallucinations and delusions
- Anxiety disorder
Chronic anxiety that interferes with daily life
What causes mental illness?
Mental health disorders are a result of social, biological and/or genetic factors.
Chemical imbalances in the brain
Everything that happens in our body starts in the brain, which processes information as we experience it. Through chemicals called neurotransmitters, the brain tells the body how to respond. For example, if you see a baseball heading your way, you reach up to catch it, or duck to avoid it.
Research indicates that malfunctioning neurotransmitters cause the brain to have problems processing information, which leads to abnormal behavior and thinking associated with mental illness.
Frightening, shocking and hurtful experiences such as emotional or physical abuse, violence, rape, natural disaster or witnessing a death can cause severe psychological trauma that triggers mental illness.
Instead, experts believe some people have a genetic tendency toward certain disorders that may or may not develop depending on other contributing factors.
