title: Research of Sleep Disorders in Patients with Acute Cerebral Infarction.
abstract: BACKGROUND
  The purpose of this study is to investigate the incidence of sleep disorders (SD), characteristic of cerebral infarction patients with different parts affected.
  
  
  METHODS
  The research selected 101 patients with a first occurrence of acute cerebral infarction as the experimental group, and 86 patients without cerebral infarction as controls. Polysomnography, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, and US National Stroke Scale were assessed.
  
  
  RESULTS
  Compared with control group, the incidence of SD was higher in experimental group (P < .05), and the incidence of SD in women was more frequent in experimental group (P < .05). There was no significant difference in the types of SD patients with acute cerebral infarction. In addition, the sleep quality of cerebral infarction patients with different parts affected was different: the sleep quality of left hemisphere infarction patients was poor compared with the right one, and the sleep quality of anterior circulation patients was poor compared with posterior circulation patients. Patients with thalamus infarction had a longer sleep time and a shorter sleep latency and stage 2 of non-rapid eye movement sleep compared with non-thalamus infarction group.
  
  
  CONCLUSIONS
  The prevalence of SD was relatively high in acute cerebral infarction patients, and the detailed classification of acute cerebral infarction may provide a more effective therapeutic method and therefore relieve patients' pain and supply a better quality of sleep.
