  • Effects of Aging and Aerobic Exercise Training on Brain Glucose Metabolism Rochester, MN

    Aging is associated with a loss of brain function and conditions such as dementia and Alzheimer's disease. It is likely that decreased brain metabolism is contributing to the progression of age related degenerative diseases. Aerobic exercise training can increase brain volumes and is associated with decreased risk for degenerative brain conditions. However, little is know about the changes that occur to brain metabolism with aerobic training and aging.

  • Exercise in Asymptomatic Pre-Alzheimer's Disease Pilot Study Jacksonville, FL

The emotional and financial burden of AD to patients, family members, and society is enormous, and is predicted to grow exponentially as the median population age increases. Current FDA-approved therapies are modestly effective at best. This study will examine a novel therapeutic approach using intranasal insulin (INI) that has shown promise in short-term clinical trials. If successful, information gained from the study has the potential to move INI forward rapidly as a therapy for AD. The study ...

  • Electroconvulsive Therapy in Severe Agitation in Alzheimer's Dementia Rochester, MN

    McLean hospital,  Mayo Clinic,  Emory University, LIJ/Northwell, and Pine Rest Mental Health are conducting a research study using Electroconvulsive therapy (ECT)  to treat agitation in dementia. ECT is a treatment done under general anesthesia, in which brief electric currents are passed through the brain to trigger a brief seizure.

  • The Impact of Cognitive Impairment on Driving Safety. Rochester, MN

    Automobile driving is a crucial aspect of everyday life, but driving safety problems including car crashes or speeding violations are a serious public health problem. Alzheimer’s Disease (AD) affects the ability to safely drive and raises crash risk. Mild cognitive impairment (MCI) raises the risk of dementia, and people with MCI have been shown to have problems with memory, decision making, and the ability to concentrate that could lead to unsafe driving, even before obvious dementia begins. Whether MCI patients who continue to drive are safe drivers or not is unknown.
