Clinical Trial Summary

This pilot study proposes to examine the effect of Rozerem on sleep/wake patterns among individuals with Traumatic Brain Injury (TBI) experiencing sleep disturbance, using both objective and subjective measures. It will also show that improvement in sleep/wake patterns resulting from Rozerem will impact daytime functioning using objective and subjective measures.

Description:

Although research has begun to examine sleep quality within the traumatic brain injury (TBI) population, most of the studies found in the research literature utilize subjective, self-report measures that can be problematic in terms of response accuracy when used with populations that have known cognitive deficits (Baños, LaGory, Sawrie, Faught, Knowlton, Prasad, Kuzniecky and Martin, 2004). Because TBI often results in a diminished capacity for self-reflective awareness, obtaining reliable sleep-related information is difficult to do through surveys alone (Fleming, Strong, Ashton, 1996; Vanderploeg, Belanger, Duchnick, and Curtiss, 2007).

A number of studies have attempted to objectify the measurement of sleep quality in TBI rehabilitation by having nursing staff keep an overnight log to document whether the patient was asleep or awake at hourly intervals (Burke, Shah, Schneider, Ahangar, & Al Aladai, 2004; Worthington & Melia, 2006). Because this results in only one single observation point per hour, it misses the nuances of the sleep/wake cycle obtained through more continuous measurement throughout the night and is still somewhat subjective and dependent on the observer's judgment.

Polysomnography, the electrophysiological measurement of sleep, is widely used in the clinical setting to diagnose sleep disorders. Using this more objective measure, Masel and colleagues (2001) found a high prevalence of posttraumatic hypersomnia, sleep apnea-hypopnea syndrome and periodic limb movement disorder that was not identified through self-report measures (Masel, Scheibel, Kimbark, & Kuna, 2001). This illustrates the limitations of self-report questionnaires and highlights the need for more objective measures. However, the high cost and inconvenience of polysomnography, requiring multiple electrodes attached to the face, head, and other parts of the body, make it less practical for research studies.

These limitations of subjective self-report measures and the cost and inconvenience of polysomnography suggest the need for alternative methods of measurement. With the use of an actigraph, a small, highly sensitive, accelerometer (motion detector) worn on the wrist over a period of days, a number of sleep-related variables can be derived through the analysis of motion and rest patterns using a computer algorithm (Coffield & Tryon, 2004). Variables such as sleep latency, total time asleep, and number of nocturnal awakenings derived through actigraphy are comparable to those obtained via polysomnography, and recent research studies demonstrate the validity of actigraph-based sleep/wake estimates among individuals with acquired brain injury (Muller, Czymmek, Thone-Otto, & Von Cramon, 2006; Tweedy & Trost, 2005; Schuiling, Rinkel, Walchenbach, & de Weerd, 2005). Thus, actigraphy represents a means of measurement that will enable the collection of objective data in the comfort of the sleeper's usual environment in a manner that is less invasive and more cost-effective than polysomnography, and more reliable than self-report measures alone.

The most widely researched treatments for sleep disturbance are problematic for individuals with TBI due to their effects on cognition and risk for dependence. With a high prevalence of sleep/wake disorders found among individuals with TBI, Rozerem is a promising treatment option to improve sleep quality that is less likely to exacerbate cognitive sequelae of TBI and less likely to result in dependence.
