10 Most Common Mental Illnesses Broken Down

By Spicevicious

 

Mental Illness Affects Us All

 

Mental illness affects–even wrecks–the lives of millions of individuals and their families every year regardless of age, cultural background, and socioeconomic status.  Here’s a quick breakdown of what the experts have to say:

 

• The Substance Abuse and Mental Health Administration (SAMHSA) says one in five adults in the United States suffered from a mental illness in 2018. That’s 65,861,320 people.
• The Journal of the American Medical Association (JAMA) tells us one in six children between the ages of 6-17 struggle with a mental illness every year.  We’re talking about 12,366,666 children in the United States.

 

Mental illness doesn’t just take an emotional toll on people who live with these disorders.  People who struggle with a mental illness are more likely than people who don’t live with mental illnesses to:

 

• develop a chronic disease at some point in their lives
• go to prison or jail
• be homeless
• commit suicide (SIDE NOTE: suicide is the second leading cause of death for individuals between the ages of 10 and 34)

 

But mental illness doesn’t only affect people living with the disorder.  Almost 8.4 million family members provide care to a mentally ill loved one.  This takes about 32 hours every week, which is about as much time as a full time job.

 

So What Do We Do About It?

 

The best place to start is by learning about mental illness—what it is, what it isn’t, how to treat it, and how to support those affected by it.  This post breaks down the 10 most common mental illnesses as reported by NIMH and the National Center for Biotechnology Information (NCBI).
