桥脑中央型髓鞘融解症(Central Pontine myeIinolysis简称CPM)于1959年由Adams等首先报导,其主要临床表现为迅速的发生下肢轻瘫或四肢瘫,伴有明显的假性球麻痹症状,如构音障碍、吞咽困难,不少患者伴有严重的水电解质紊乱以及低血压.脑干听觉诱发反应(Brain stem audifory-evoked responses)有助于本病的诊断. Central Pontine myelinysis (CPM) was first reported by Adams et al in 1959. Its main clinical manifestations were rapid paraplegia or quadriplegia accompanied by obvious symptoms of pseudobulbar palsy, such as Dysarthria, dysphagia, and many patients with severe water and electrolyte disturbances and hypotension. Brain stem auditory evoked responses (Brainstem auditory evoked responses) contribute to the diagnosis of the disease.
