     hard.]
     1. (Med.) Induration; hardening; especially, that form of

     Cerebro-spinal sclerosis (Med.), an affection in which
        patches of hardening, produced by increase of the
        neuroglia and atrophy of the true nerve tissue, are found
        scattered throughout the brain and spinal cord. It is
        associated with complete or partial paralysis, a peculiar
        jerking tremor of the muscles, headache, and vertigo, and
        is usually fatal. Formerly referred to as multiple
        sclerosis, disseminated sclerosis, or insular
        sclerosis, but now usually called only multiple
        sclerosis, or MS.
        [1913 Webster +PJC]
