The social security administration defines disability as any physical or mental problem that prevents you from working; the condition must be expected to last at least a year, or result in death. Unlike some programs, social security does not pay for partial or short-term disability. It is intended to provide income for you and your family when you are unable to do any type of work for which your are suited. If you've worked under social security in the past, and are now disabled, you or your dependents may be eligible for social security disability benefits. If so, you will receive checks each month. Benefits will continue for as long as you are disabled, and cannot resume work. A person can receive social security disability at any age. If you are getting disability benefits at age 65, they become retirement benefits, but the amount stays the same.
