Ssi ( not SS)

From the Social Security Administration website: Definition of Disability For all individuals applying for disability benefits under title II, and for adults applying under title XVI, the definition of disability is the same. The law defines disability as the inability to engage in any substantial gainful activity (SGA) by reason of any medically determinable physical or mental impairment(s) which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months. Unless your diagnosis is one that appears on the Compassionate Allowance List the evidence in your case must meet the definition of disability described above.  Another approach to the definition is if your condition prevents you from working 8 hours per day, 5 days per week on a regular and consistent basis, you can be found to be disabled. The individual facts and limitations are different in every case.  Consulting a professional in your area is always a good idea.
