About
The purpose of the research is to see how simvastatin affects a substance in the body called beta-amyloid. Beta-amyloid is found in the brain and in the liquid around the brain and spinal cord. High amounts of beta-amyloid may be associated with a greater risk of getting Alzheimer's disease. This study will see if simvastatin can lower the amount of beta-amyloid in the spinal fluid. This study will also see if simvastatin affects memory and thinking, blood flow in the brain, and blood vessel function. The investigators hope that future studies show whether simvastatin might prevent memory loss and decrease the chance of developing Alzheimer's disease.
Full description
Studies show that some medicines that lower cholesterol may reduce the risk of developing Alzheimer's disease, but this has not yet been proven in humans. We are looking for individuals to participate in this study to see if a cholesterol-lowering medication, called simvastatin affects blood flow to the brain, blood vessel function and a substance in the spinal fluid related to the changes in Alzheimer's disease.
The SHARP study included 88 adults ages 40-72 with parental history of documented Alzheimer's disease. The study had 9 visits over the course of 18 months. Participants had fasting blood tests collected, completed a medical history questionnaire and medication side effect review, underwent lumbar puncture procedure, completed memory testing, and had ultrasound and MRI procedures. Participants were randomly assigned to receive either simvastatin or a placebo each night for 18 months.
