I am disabled by mental illness. Can mental illness serve as the basis for a Social Security Disability claim?

Yes, mental illness is in fact a listing of impairments within the Social Security law. For example, some who suffers from depression, or anxiety, or post-traumatic stress disorder, or schizophrenia, or bipolar syndrome, can qualify for Social Security Disability benefits, under the listings. You should contact a Social Security Disability attorney to determine whether or not you meet those qualifications, and how to go about following through with your case.
