Key result
Patients in a vegetative state had significantly more disrupted circadian rhythms measured by actigraphy compared to those in a minimally conscious state.
Why the study?
Does actigraphy detect differences in circadian rhythm disruption between patients in a vegetative state versus a minimally conscious state?

Actigraphy reveals that circadian rhythms are more disrupted in vegetative state patients compared to minimally conscious state patients, providing a potential tool for prognostication and rehabilitation strategies.
In a study by Cruse et al. published in BMC Medicine, patients with severe brain damage who were in the Vegetative or Minimally Conscious States (VS or MCS, respectively) from traumatic and nontraumatic etiologies had assessments of circadian rhythms using an actigraph, a device worn on a limb to evaluate circadian rhythmicity, in this population. This is a novel approach and is being used as a surrogate for polysomnography and other reference standards. Cruse et al. showed more disruption in circadian rhythms in the VS when compared to the MCS. This suggests that more brain injury occurs in the areas that control circadian rhythmicity in VS than in MCS patients. The study provides opportunities for improved prognostication and rehabilitation strategies in this patient population.

Sen et al. (2013) conducted an editorial in Severe brain damage (Vegetative State or Minimally Conscious State) (n=55). Vegetative State vs. Minimally Conscious State was evaluated on Disruption of circadian rhythms measured by actigraphy. Patients in a vegetative state had significantly more disrupted circadian rhythms measured by actigraphy compared to those in a minimally conscious state.
