Feasibility of Improving Glycemia With Heat Therapy to Prevent AD

Enrolling By InvitationNA

Sponsor: University of Kansas Medical Center

Conditions: Healthy Aging, Alzheimer Disease, Metabolic Disease

Interventions: Water Immersion Heat Therapy

Countries: United States

The investigators will determine if heat therapy can improve blood (Aim 1) and brain (Aim 2) glucose metabolism in cognitively healthy older adults (65+) who are at risk for AD. The investigators will also examine the degree to which changes in blood and brain glucose metabolism track together and explore several additional potential mechanisms that are critical to understanding the brain benefits of heat therapy (Aim 3). These aims will provide a comprehensive understanding of the impact of heat therapy on whole body metabolic function and brain health.

* Myocardial infarction or symptoms of coronary artery disease in the last 2 years.
* History of or current diagnosis of disorders with the potential to impair cognition (i.e. AD, Parkinson's disease, stroke (defined as clinical episode w/ neuroimaging evidence in appropriate area to explain symptoms)).
* Insulin-dependent (Type 1) Diabetes Mellitus.
* Clinically significant chronic disease such as cancer, HIV, or acquired immunodeficiency syndrome.
* Clinically significant depressive symptoms that may impair cognition, use of psychoactive and investigational medications, and significant visual or auditory impairment.
* Orthopedic complications that would preclude individuals from safely entering a hot tub.
