[A new case of chronic progressive bulbo-pontine paralysis and deafness].

The author reports a new case of chronic progressive bulbo-pontine paralysis with deafness. This case differed from other cases previously published on the basis of the later age of onset of labio-glosso-laryn-geal paralysis, by the absence of any vestibular changes despite bilateral involvement of the acoustic centres and above all by the normality of deep tendon reflexes. The author feels that chronic progressive vulvo-pontine paralysis with deafness is a specific individual condition, worthy of consideration as an autonomic clinical entity.
