Mental Health and Substance Use Disorders are Interwoven
Every year, about 42.5 million American adults (or 18.2 percent of the total adult population in the United States) suffers from some mental illness, enduring conditions such as depression, bipolar disorder or schizophrenia, statistics reveal.
The data, compiled by the Substance Abuse and Mental Health Services Administration (SAMHSA), also indicate that approximately 9.3 million adults, or about 4 percent of those Americans ages 18 and up, experience “serious mental illness” – that is, their condition impedes day-to-day activities, such as going to work.
This data does not diverge greatly from the last SAMHSA report, released in 2012, which found that 45.9 million American adults, 20 percent of this demographic, experienced mental illness at least once annually. (Though there is a 1.8 percent difference, the statistics do have margins of error, and methods of compiling them are often revised, so this dip does not necessarily mean there has been a long-term decline in mental illness.)
Perhaps more importantly, only 62.9 percent of adults nationwide with serious mental illness received mental health treatment in the year they reported this illness.
