The Social Security Administration will aggressively fight your case if you are under 50 years old. The Social Security Administration’s own rules support their tougher stance against claimants less than 50 years old. This is legal age discrimination built into the rules and regulations used by the Social Security Administration. This creates problems for those under 50 years old that really need disability because of a severe impairment. It is fair to say there is an automatic suspicion by the Social Security Administration for anyone under 50 years of age applying for disability. This is because, normally, our limitations increase as we age. The Social Security Administration will assume you can adjust to some form of regular work if you are less than 50 years old. If you fall within this age category, you will need substantial evidence to prove your case. However, it can be done with the right medical evidence. You will need a functional capacity report signed by a medical doctor or psychologist, supported by medical notes and medical tests.
