Learn the Facts
One of the best ways you can help someone with mental illness is by understanding what it is — and what it isn't. After all, myths about mental illnesses contribute to stigma, which in turn prevents those who are living with one from seeking help.The fact is, a mental illness is a disorder of the brain — your body's most important organ — and 1 in 6 adults lives with a brain-related illness including depression, bipolar disorder, PTSD and schizophrenia.
Like most diseases of the body, mental illness has many causes — from genetics to other biological, environmental and social/cultural factors. And just as with most diseases, mental illnesses are no one's fault. The unusual behaviors associated with some illnesses are symptoms of the disease — not the cause.
But most importantly, mental illnesses are treatable through medication and psychosocial therapies — allowing those who live with them the opportunity to lead full and productive lives.
