National Alliance of Mental Illness (NAMI)
NAMI, the National Alliance on Mental Illness, is the nation’s largest grassroots mental health organization dedicated to building better lives for the millions of Americans affected by mental illness.
What started as a small group of families gathered around a kitchen table in 1979 has blossomed into the nation's leading voice on mental health. Today, we are an association of hundreds of local affiliates, state organizations and volunteers who work in your community to raise awareness and provide support and education that was not previously available to those in need.
Know The Warning Signs
Trying to tell the difference between what expected behaviors are and what might be the signs of a mental illness isn't always easy. There's no easy test that can let someone know if there is mental illness or if actions and thoughts might be typical behaviors of a person or the result of a physical illness.
Mental Health Conditions
A mental health condition isn’t the result of one event. Research suggests multiple, linking causes. Genetics, environment and lifestyle influence whether someone develops a mental health condition. A stressful job or home life makes some people more susceptible, as do traumatic life events like being the victim of a crime. Biochemical processes and circuits and basic brain structure may play a role, too.
