Determinations with respect to disability

§ 502. Determinations with respect to disability (a) For the purposes of this chapter, a person shall be considered to be permanently and totally disabled if he is suffering from— (1) any disability which is sufficient to render it impossible for the average person to follow a substantially gainful occupation, but only if it is reasonably certain that such disability will continue throughout the life of the disabled person; or (2) any disease or disorder determined by the Administrator to be of such a nature or extent as to justify a determination that persons suffering therefrom are permanently and totally disabled. (b) For the purposes of this chapter, a person shall be considered to be in need of a regular aid and attendance if he is helpless or blind, or so nearly helpless or blind as to need or require the regular aid and attendance of another person.
