1. Mental health statistics: prevalence and treatment MORE
A mental illness is a condition that impacts a person's thinking, feeling or mood and may affect his or her ability to relate to others and function on a daily basis.
Approximately 1 in 25 adults in the U.S., or 10 million, experiences a serious mental illness (e.g. schizophrenia, bipolar disorders, post-traumatic disorders) in a given year that substantially interferes with or limits one or more major life activities.
Only 41% of adults in the U.S. with a mental health condition received mental health services in 2014. Among adults with a serious mental illness, 63% received mental health services in 2014.
