If you age is equivalent to full retirement age, then yes you are too old to receive Social Security Disability Benefits.  You will only be entitled to Social Security Retirement benefits.   Depending on when you became disabled, you might be entitled to some past due benefits but no current.  If at your age (i.e. 62), you are only entitled to partial retirement benefits, then you would be eligible for partial Social Security Disability Benefits until reaching full retirement age.
