It is often more difficult for disability applicants to get Social Security disability benefits for medical "syndromes" for a variety of reasons. Many of these syndromes are often based on the disability applicant's subjective reports of pain and other symptoms and, as a result, applicants have historically had a hard time convincing Social Security that their impairments are real and disabling. In addition, Social Security does not have official listings for most syndromes (with the exception of non-Mosiac Down syndrome), so in most cases there's no way to automatically qualify for disability benefits by meeting a fixed set of criteria.
The following articles explain what Social Security will be looking for when evaluating an applicant's disability claim based on that medical condition.
