About this study
Official title: An Observational Epidemiological Study on Evaluation of Sleep Quality in Patients With Mild to Moderate Alzheimer's Disease in Clinical Practice
The purpose of this study is to evaluate sleep quality in patients with mild to moderate Alzheimer's disease treated with anticholinesterase drugs in clinical practice.
Read the detailed description
This is an epidemiological (the study of health-related states or events in specific populations) study of patients with mild to moderate Alzheimer's who have been treated previously with anticholinesterase drugs (class of drugs that act in the central nervous system) up to a maximum of fifteen days. The data for each patient will be recorded on two occasions; first at a baseline visit and then at a follow-up visit at 3 months. At the baseline visit, after the patient or his/her legal representative has given written informed consent, each participating neurologist will use the study questionnaire to collect patient sociodemographic characteristics (characteristics such as age, years of education, race, sex, religion, birthplace, income, occupation, geographic location, among others), medical history and diagnosis of Alzheimer's disease. The neurologist will also record treatment for Alzheimer's disease and concomitant hypnotic medications (simultaneous use of medications that induce sleep) and evaluate the patient using two scales: the Pittsburgh Sleep Quality Index (PSQI) to record sleep disturbances and the Epworth Sleepiness Scale to determine the level of daytime sleepiness. Alzheimer treatment and concomitant hypnotic medications will be recorded again at the follow-up visit. Patient sleep quality using the PSQI and daytime sleepiness using the Epworth scale will also be evaluated again at this visit.

What is being measured
The primary outcome is the main question the study is designed to answer.
Sleep disturbances measures by Scores on the Pittsburgh Sleep Quality Index (PSQI) Scale
The PSQI consists of 19 self-rated questions which assesses sleep quality and disturbances over 1-month time interval. The 19 questions assess a wide variety of factors relating to sleep quality, including estimates of sleep duration and the frequency and severity of specific sleep-related problems. These 19 items are grouped into seven components scores, each weighted equally on a 0-3 scale. The seven components scores are then summed to yield a global PSQI score, which has a range of 0-21; higher scores indicate worse sleep quality.
Measured: Up to 3 months
Secondary outcomes (1)
The Level of Daytime Sleepiness determined by the Scores on the Epworth Sleepiness Scale
The Epworth Sleepiness Scale measures how likely, from 0 (would never take a nap) to 3 (high change of dozing), the patient is to doze off or fall asleep in common everyday situations. The scores for a total of eight questions are added together to obtain a single number. A number in the 0-9 range is considered to be normal while a number in the 10-24 range indicates that expert medical advice should be sought.
Measured: Up to 3 months

The record says: finished, as of the sponsor's last update on 31 Oct 2012. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Sleep disturbances measures by Scores on the Pittsburgh Sleep Quality Index (PSQI) Scale (time frame: Up to 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Oct 2012.
