Filter by:The purpose of this study is to examine the effects of (a) quetiapine XR and (b) mirtazapine on sleep when given as an antidepressant (monotherapy). We hypothesize that (a) quetiapine XR has an immediate and lasting positive effect on sleep in depressed patients which does not differ from the impact of mirtazapine on sleep in this group of patients; (b) in the context of a secondary objective, we expect an antidepressant effect of quetiapine XR which is equivalent to that of mirtazapine.
This study will examine whether various drugs affecting sleep cycles can improve different kinds of memory.
Available data suggest that obtaining adequate sleep is associated with a better ability of the body to use carbohydrates as a source of energy and a lower risk of developing diabetes. The sleeping pill, Eszopiclone (Lunesta), has been approved by the Food and Drug Administration for the treatment of people who complain of trouble falling or staying asleep. This study will examine the hypothesis that the use of Eszopiclone (Lunesta) to improve the sleep of people with insomnia may also improve the use of sugar in their body.
The use of energy from food changes when people sleep. However, it is still not known if differences in the amount of nighttime sleep have an effect on the amount of energy that people who have a relative with type 2 diabetes (parent, sibling, or grandparent) use to perform their daily activities. This study is being done to test the hypothesis that the daily use of energy in people who have a history of type 2 diabetes in their family will be different after they have slept short hours for 16 days in comparison to when they have slept longer hours for 16 days.
Currently, it is not known if the amount of nighttime sleep has any effect on the overall physical fitness, and on how much energy do people who have a relative with type 2 diabetes (parent, sibling, or grandparent) use to perform activities of daily living. This study will test the hypothesis that individual differences in nighttime sleep duration are related to differences in the amount of energy used to perform activities of daily living and the overall level of physical fitness of the individual.
The use of sugar and starch-like foods for energy (carbohydrate metabolism) changes when people sleep. However, it is still not known if differences in the amount of nighttime sleep have an effect on the carbohydrate metabolism of people who have a relative with type 2 diabetes (parent, sibling, or grandparent). This study is being done to test the hypothesis that the carbohydrate metabolism of people who have a history of type 2 diabetes in their family will be different after they have slept short hours for 10 days in comparison to when they have slept longer hours for 10 days.
The use of sugar and starch-like foods for energy (carbohydrate metabolism) changes when people sleep. However, it is still not known if differences in the amount of nighttime sleep have an effect on the carbohydrate metabolism of people who have a relative with type 2 diabetes (parent, sibling, or grandparent). This study is being done to test the hypothesis that individual differences in habitual sleep duration may be related to differences in the carbohydrate metabolism of people who have a history of type 2 diabetes in their family.
The hypothesis is that pseudoephedrine, a sympathomimetic amine commonly used as a decongestant, will decrease nasal congestion leading to increased patency of the nose and a decrease in nighttime sleep fragmentation in individuals with year round perennial allergic rhinitis (PAR). This decrease in sleep fragmentation will reduce daytime somnolence and fatigue.
The hypotheses of this study are: In the older population with knee OA, - When acupoints are chosen for both sleep and pain, there are additive effects on sleep improvement and pain relief (i.e. no interaction). - Main effects of acupuncture on sleep improvement and pain relief are anticipated when acupoints are separately targeted for sleep and for pain, respectively.
The purpose of our study is to survey the quality of sleep and sleep disordered breathing in a HIV infected inner city ambulatory African-American Population aged 50 years and older. Hypothesis: African-American HIV infected individuals aged 50 years and older have a high prevalence of sleep disorders and lower quality of sleep.
