This is a three-year study to determine if estrogens can prevent memory loss and Alzheimer's disease in women with a family history of Alzheimer's disease.
This is a randomized placebo controlled, double blind study. Patients who meet eligibility criteria and decide to participate in the study will be randomly assigned to receive either drug treatment or a placebo. Neither the patients nor the participating investigators will know who is receiving the drugs and who is receiving the placebo. Participation involves 15 outpatient clinic visits over a 68 week period. Patients take study medication at varying doses (the maximum dose is 20 mg daily), along with calcium and vitamin supplements.
Agitation affects 70 to 90 percent of patients with AD. Signs of agitation include verbal and physical aggressiveness, irritability, wandering, and restlessness. These behaviors often make caring for patients at home very difficult. Trazodone and haldol are two of the most commonly prescribed drugs for agitation in AD patients. Behavior management, a non drug approach, has been effective in reducing signs of agitation. Researchers have yet to compare the effectiveness of drug versus non drug therapy to treat agitation in AD patients and determine which is the best treatment. The Alzheimer's Disease Cooperative Study, with funding from the National Institute on Aging, is conducting an agitation treatment program at 21 sites in 16 States. This study will assess which of the above treatments is most effective.
AIT-082 is a novel small molecule that crosses the blood-brain barrier to enhance nerve function by increasing levels of neurotrophic growth factors and encouraging nerve sprouting in the brain. Preclinical studies in animals have shown that AIT-082 improves memory in aged animals and in animals with neurological deficits. This study was a double-blind placebo-controlled safety study that was designed to study whether AIT-082 may delay age-related mental decline. Eight healthy older volunteers at two clinical sites were given single, weekly, rising doses of AIT-082 or placebo for 5 weeks; were tested for side effects and absorption; and underwent a battery of neuropsychological memory tests, including word and number recall tests.
The purpose of this study is to conduct human laboratory studies of possible cocaine interactions with various potential treatment medications.
The purpose of this study is to evaluate the effects of pergolide on cocaine taking and on the physiological and subjective effects of cocaine, including cocaine craving in non-opiate dependent cocaine users.
The purpose of this study is to compare the clinical efficacy of maintenance on low and high doses of buprenorphine with methadone for cocaine abusing opiate addicts.
