title: Comparison of symptoms of delirium across various motoric subtypes.
abstract: OBJECTIVE
  The aim of this study was to determine the correlation between delirium motor subtypes and other symptoms of delirium.
  
  
  METHODS
  Three hundred and twenty-one (n = 321) consecutive patients referred to consultation-liaison psychiatry services were evaluated on Delirium Rating scale-Revised-98 version and amended Delirium Motor Symptom Scale.
  
  
  RESULTS
  Half of the patients had hyperactive subtype (n = 161; 50.15%) delirium. One-quarter of the study sample met the criteria for mixed subtype (n = 79; 24.61%), about one-fifth of the study sample met the criteria for hypoactive delirium subtype (n = 64; 19.93%), and only very few patients (n = 17; 5.29%) did not meet the required criteria for any of these three subtypes and were categorized as 'no subtype'. When the hyperactive and hypoactive subtypes were compared, significant differences were seen in the prevalence of perceptual disturbances, delusions, lability of affect, thought process abnormality, motor agitation and motor retardation. All the symptoms were more common in the hyperactive subtype except for thought process abnormality and motor retardation. Compared to hyperactive subtype, the mixed subtype had significantly higher prevalence of thought process abnormality and motor retardation. Significant differences emerged with regard to perceptual disturbances, delusions, lability of affect and motor agitation when comparing the patients with mixed subtype with those with hypoactive subtype. All these symptoms were found to be more common in the mixed subtype. No significant differences emerged for the cognitive symptoms as assessed on Delirium Rating scale-Revised-98 across the different motoric subtypes.
  
  
  CONCLUSIONS
  Different motoric subtypes of delirium differ on non-cognitive symptoms.
