There is one clinical trial.
Nighttime agitation in persons with Alzheimer's disease causes patient suffering, distresses caregivers, and often results in prescriptions for harmful antipsychotics. Effective treatments are lacking because of limited knowledge of the etiology of nighttime agitation. The investigators propose a clinical trial to better elucidate whether a sleep disorder, restless legs syndrome, may be a mechanism for nighttime agitation, and if treatment with gabapentin enacarbil (Horizant®) reduces nighttime agitation, improves sleep, reduces restless legs syndrome behaviors, and reduces antipsychotic medications.
Description: The CMAI, modified for direct nighttime observation, will be used to collect objective data on nighttime agitation. Research Assistants (RAs) continuously observe the persons with dementia and record agitation behaviors every 5 minutes. The measure requires that the RAs first note whether the participant is behaviorally awake or asleep. Sleep is defined as a quiet state with eyes closed. Nighttime agitation behaviors are scored during wake. The RA will directly observe the participant when he, or she, is out of bed and record the observations using the CMAI. After the participant has gone to bed, the RA will observe him, or her, via a video camera placed in the bedroom and a small handheld monitor located in a hallway or room adjacent to the bedroom. The monitor will be shielded from view of non-research personnel when on, and turned off between 5-minute observations. The RAs will endeavor to be as sensitive as possible to the privacy of participants.
Measure: Nighttime Agitation - Cohen Mansfield Agitation Inventory (CMAI) - Direct Observation Time: Change from baseline at 2 and 8 weeksDescription: The same primary caregivers, if possible, on the evening and night shifts will each complete the CMAI Caregiver Version at baseline and 8 weeks.
Measure: Nighttime Agitation - Cohen Mansfield Agitation Inventory (CMAI) - Caregiver Version. Time: Change from baseline at 2 and 8 weeksDescription: The mADCS-CGIC measures clinically meaningful change in the patient's condition relative to baseline on a 7-point Likert scale (markedly worse to markedly improved). The scale was modified to assess items specific to agitation, producing global ratings of change in agitation. This scale will be completed by the study Advanced Practice Nurse (APN) based on physical examination and interviews with nursing home caregivers and persons with dementia (if able).
Measure: Nighttime Agitation - Modified Alzheimer's Disease Cooperative Study-Clinical Global Impression of Change (mADCS-CGIC). Time: Change from baseline at 2 and 8 weeksDescription: The RA will continuously observe the participant in the evening and night and note every 5 minutes whether the participant is behaviorally awake or asleep. The sleep disturbance outcome will be collected at baseline and 8 weeks. Sleep and wake will be defined as percent of observations asleep or awake on Night 1, 5 pm-10 pm; and Night 2,10 pm-7am. The investigators have chosen to observe on 2 nights at different times to capture any night-to-night and time of night variability in sleep.
Measure: Sleep Disturbance - Direct Observation Time: Change from baseline at 2 and 8 weeksDescription: The BIT-RL consists of two parts: 1) Behavioral Indicators - direct observations for RLS behaviors, such as kicking or rubbing legs (8 items), and 2) Clinical Indicators - medical history or family informant interview (3 items), interviews with caregivers (2 items), and an interview with the resident with dementia (1 item). The research assistants (RAs) will continuously observe each participant for RLS behaviors for 20 minutes on one evening, between 6 pm and the usual bedtime. The study APN will assess for the Restless Legs Syndrome Clinical Indicators by reviewing the medical records, and interviewing family members, evening and night shift nurses, and participants. One item, leg discomfort (yes or no) requires an answer from the participant with dementia. The APN will assess for discomfort in legs in the evening during the interval when the evening nurses report that the participant with dementia is most restless.
Measure: Sleep Disturbance - Behavioral Indicators Test - Restless Legs (BIT-RL) Time: Change from baseline at 2 and 8 weeksDescription: The micro-mini actigraph is wristwatch-sized accelerometer worn on the wrist. In the investigators' previous studies with over 400 nursing home residents with dementia the investigators have "locked" the actigraph on the participant's wrist with a plastic tie that is comfortable to wear, yet difficult to remove. The actigraph is waterproof and can be left on during showers. Nighttime total sleep time is the main actigraphy sleep outcome. The investigators also will measure other sleep disturbance variables, including nighttime wake after sleep onset, sleep efficiency, sleep latency, and awakenings with the actigraph. Daytime will be defined as 7 am-7 pm, and nighttime will be defined as 7 pm- 7 am. Because the investigators have found that sleep varies in persons with dementia and multiple nights are often needed to obtain a more reliable measure, the investigators will measure sleep for 7 days and nights at baseline and 7 days and nights at 8 weeks.
Measure: Sleep Disturbance - Micro-Mini Motionlogger® Actigraph Time: Change from baseline at 2 and 8 weeksDescription: This is a single question measure: "How do you judge the risk that Mr. or Mrs. X will fall within 6 months - high or low?" asked at baseline, week 2, and week 8 of a nurse or aide with personal knowledge of the resident. If possible, the same nurse, aide, or caregiver will complete the GLORF each week.
Measure: Fall Risk and Cognition - Global Rating of Fall Risk (GLORF) Time: Change from baseline at 2 and 8 weeksDescription: The MMSE (range 0-30) is a 30-item cognitive screen measuring orientation, registration, short-term memory, attention/concentration, language and constructional capacity. The MMSE is a widely used screening test of cognition and takes about 10 minutes to administer to the person with dementia.
Measure: Mini-Mental State Examination (MMSE) Time: Change from baseline at 2 and 8 weeksDescription: The Physical Mobility Scale (PMS) is an 8-item performance-based scale routinely used to assess mobility of elderly persons living in long-term care facilities.

An HTML report was created for each of the unique drugs, MeSH, and HPO terms associated with COVID-19 clinical trials. Each report contains a list of either the drug, the MeSH terms, or the HPO terms. All of the terms in a category are displayed on the left-hand side of the report to enable easy navigation, and the reports contain a list of correlated drugs, MeSH, and HPO terms. Further, all reports contain the details of the clinical trials in which the term is referenced. Every clinical trial report shows the mapped HPO and MeSH terms, which are also hyperlinked. Related HPO terms, with their associated genes, protein mutations, and SNPs are also referenced in the report.
