Recognizing the Signs of Mental Illness

April 2nd, 2018

DepressionIf you are feeling isolated or insecure because you believe you may be suffering from a mental illness, know that you are not alone. Mental illness is defined, broadly, as a disease that causes mild to severe disturbances in thought and/or behavior, resulting in an inability to cope with life’s ordinary demands and routines. The National Alliance on Mental Illness (NAMI) estimates that in any given year, approximately one in five U.S. adults, or 18.5 percent of the population, experiences mental illness. The number of people who suffer from a mental illness is in part so vast because there are more than 200 classified forms of mental illness, including depression, bipolar disorder, dementia, schizophrenia, and anxiety disorders.

With an understanding that mental illness affects millions of individuals, it should not be a phrase whispered guiltily, or held inside. Instead, all Americans should be aware of the signs and symptoms of mental illness so that they can proactively help themselves, or a loved one, obtain support and help for these treatable conditions. What follows is a list of general signs and symptoms that may indicate that you or a loved one have a mental illness. While its own set of specific symptoms accompanies each diagnosis, what follows are general signs that often indicate the presence of an underlying condition. If reading this list reinforces your belief that your feelings may be caused by a mental health disorder, speak with a mental health expert and ask for help.
