  • Hachinski Ischemia Scale less than 5
  • Mini-Mental State Examination score of 0 to 26
  • Actigraph evidence of a mean time immobile of less than 7 hours per night based on at least 7 nights of complete actigraph data collected over a single week
  • Four-week history of sleep disorder behaviors, occurring at least once weekly, as reported by the caregiver using the Neuropsychiatric Inventory (NPI) Nighttime Behavior scale
  • Sleep disturbance observed was not present before the diagnosis of AD
  • Other co-morbidities, especially delirium, depression, chronic pain and medication use may be present, but do not cooperate in the primary symptoms
  • Computed tomography or magnetic resonance imaging since the onset of memory problems showing no more than 1 lacunar infract in a nonstrategic area and no clinical events suggestive of stroke or other intracranial disease or normal
  • Stable medications for 4 weeks prior to the screening visit
  • Having a mobile upper extremity to which to attach an actigraph
  • Residing with a responsible spouse, family member, or professional caregiver who is present during the night and would agree to assume the role of the principle caregiver for the 3-week protocol
  • Ability to ingest oral medication and participate in all scheduled evaluations

You may not qualify if:

  • Sleep disturbance associated with an acute illness, delirium or psychiatric disease
  • Clinically significant movement disorder, such as akinesia, that would affect actigraphic differentiation of sleep and wakefulness
  • Severe agitation
  • Unstable medical condition
  • Discontinuation of psychotropic or sleep medication within 2 weeks of the screening visit
  • Patient unwilling to maintain caffeine abstinence after 2:00pm for the duration of the protocol
