Filter by:The aim of the study is to evaluate the risk of Down syndrome during the first trimester of the pregnancy. The risk assessment is evaluated using early ultrasound and maternal biochemical markers.
This is a study to assess whether memantine is effective and safe in preventing age related cognitive deterioration and dementia in people with Down's syndrome (DS) age 40 and over. The study will last for a year and it will include 180 people with Down's syndrome with and without dementia. Participants will be assessed on memory skills, attention and problem solving abilities. Quality of life and abilities for everyday living skills will also be regularly checked. Primary Aims Clinical: - To determine the clinical efficacy of memantine versus placebo in preventing cognitive decline in people with DS. - To compare the safety and tolerability of memantine versus placebo in people with Down’s syndrome (DS). Biochemical and pathological: - To examine the ability of memantine to alter markers of disease progression in DS patients. Secondary Aims Clinical: - To determine whether memantine has, as compared with placebo, a significant positive impact on: - level of independent functioning as measured by the carer-rated adaptive behavioural scale, (ABS) in adults with DS; - quality of life in adults with DS. Biochemical and pathological: - To investigate putative markers of memantine’s mechanism of action in peripheral samples from living patients with DS.
The goal of this study is to determine the safety and efficacy of the administration of vitamin E, which has been shown to delay the progression of Alzheimer's disease, in slowing the rate of cognitive/functional decline in older persons with Down syndrome.
Too much or too little genetic information (chromosome material) can cause abnormal development of the fetus or death. Each year approximately 2.5 million pregnant women are screened for Down Syndrome using invasive screening methods (amniocentesis or chorionic villus sampling). This 11 center study of 38,000 women will compare the accuracy of the several non-invasive tests in the first and second trimesters of pregnancy versus amniocentesis or diagnosis at birth to diagnose aneuploidy or Down Syndrome.
To create a registry of all Oregon children undergoing surgical repair of congenital heart disease since 1958 in order to determine mortality, morbidity, and disability after surgery and to assess the safety of pregnancy in women with corrected congenital heart disease and the risk of prematurity and occurrence of congenital heart defects in offspring.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells. PURPOSE: Phase III trial to study the effectiveness of combination chemotherapy in treating children who have Down syndrome and myeloproliferative disorder, acute myelogenous leukemia, or myelodysplastic syndrome.
The Cognitive Neuroscience Section of the National Institute of Neurological Disorders and Stroke proposes to continue its cross-sectional and longitudinal studies of cerebral metabolism in frontal lobe dementias and atypical basal ganglia disorders. These studies include repeated assessments of neuropsychological and brain anatomical and metabolic function in subjects with these important and possibly related brain disorders.
