Outcome Measures

Primary Outcomes (1)

  • Change in Sleep Quality

    Sleep quality will be assessed objectively through EEG measures (changes from baseline in length of non-REM sleep, length of REM sleep, and length of N3 sleep--all assessed in minutes) and subjectively, utilizing a post sleep questionnaire to assess the difference in quantity of sleep (minutes) from baseline. Sleep quality is directly related to these measures of sleep quantity.

    Approximately 8 hours

Secondary Outcomes (1)

  • Performance on a Psychomotor Vigilance Test (PVT) After Waking up From Sleep

    Approximately 30 minutes after waking up

Study Arms (2)

Healthy Control Subjects: Zolpidem, Then Dexmedetomidine

EXPERIMENTAL

This arm will enroll healthy control subjects, who will receive a regular nights sleep followed by a night of Zolpidem induced-sleep and then a night of Dexmedetomidine induced-sleep.

Drug: DexmedetomidineDrug: Zolpidem

Healthy Control Subjects: Dexmedetomidine, Then Zolpidem

EXPERIMENTAL

This arm will enroll healthy control subjects, who will receive a regular nights sleep followed by a night of Dexmedetomidine induced-sleep and then a night of Zolpidem induced-sleep.

Drug: DexmedetomidineDrug: Zolpidem

Interventions

A dose of dexmedetomidine will be administered at 1mcg/kg over 10 minutes. Subjects will never receive active drugs (Zolpidem or dexmedetomidine concurrently).

Also known as: Precedex
Healthy Control Subjects: Dexmedetomidine, Then ZolpidemHealthy Control Subjects: Zolpidem, Then Dexmedetomidine

12.5 mg of oral Ambien CR. Subjects will never receive active drugs (Zolpidem/Ambien or dexmedetomidine concurrently).

Eligibility Criteria

Age18 Years - 35 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • Subjects will be deemed "Insomniacs" if they suffer from any of the following:
  • Subject will be required to meet the criteria for insomnia, set by the International Classification of Sleep Disorders, which requires that a patient have difficulty initiating or maintaining sleep that is not accounted for by another sleep disorder, neurologic or psychiatric disorder or substance or medication.
  • Subject will be required to not be on any current pharmacological sleep disorder treatment.
  • Between the ages of 18 and 35 years.
  • Not taking any prescription medications that alter sleep, cognitive functions, or both.

You may not qualify if:

  • Abnormal sleep habits:
  • sleeping less than 5 hours each night;
  • going to sleep before 9:00 PM or after 2:00 AM on a regular basis; or
  • Waking up before 5:00 AM or after 10:00 AM on a regular basis. This will be objectively assessed by wrist actigraphy measured for a 1-week duration prior to the first study night.
  • A sleep latency greater than 60 minutes, greater than 3 awakenings per night. This will also be objectively assessed by wrist actigraphy.
  • A score greater than or equal to 10 on the Epworth Sleepiness Scale.
  • Takes medication that alters sleep, cognitive function, or both.
  • Has a history of a known neurological or psychiatric problem.
  • Younger than 18 or older than 35 years of age.
  • Known or suspected sleep disorder(s).

Limitations and Caveats

Insomniac patients were not conducted as originally proposed due to difficult enrollment. The Motor Sequence Task was not performed as originally proposed, so it has been removed as a secondary outcome measure.
