title: [Brachial diplegia as a variant of amyotrophic lateral sclerosis (Vulpian-Bernhart syndrome): the first case reported in Mexico and a review of the literature].
abstract: BACKGROUND
  Brachial diplegia refers to an atypical clinical variant of amyotrophic lateral sclerosis (ALS), which is defined as a lower motor neuron disease in the upper limbs, with no significant functional complications in other regions.
  
  
  METHODS
  A 65-year-old female who presented a clinical picture of brachial diplegia that slowly progressed over a period of 72 months. Neurophysiology studies revealed a chronic denervation process. Throughout a follow-up lasting one year the clinical course remained stable.
  
  
  CONCLUSIONS
  Brachial diplegia in females is a rare form of presentation of ALS and they probably have a higher survival rate than males.
