Blood-based Biomarkers for Diagnosis of Alzheimer's
Alzheimer's disease (AD) may currently be diagnosed using molecular biomarkers in cerebrospinal fluid (CSF) and/or positron emission tomography (PET). These diagnostic procedures are highly accurate, but the high cost and low availability hamper their feasibility. Recently, ultrasensitive blood tests predicting Alzheimer pathologies in the brain have been developed. These tests …
Study to Evaluate the Effect of HT-4253 for the Prevention of Alzheimer's Disease in APOE4 Carriers
Primary Objectives: To demonstrate that HT-4253 improves the amyloid risk profile by transitioning biomarker-positive APOE4 carriers from a positive, high risk APS2 score to a negative, low risk APS2 score. Secondary Objectives: To assess the effects of HT-4253 on tau related blood biomarker progression over the study period. To assess …
Positive Psychology for Early Cognitive Decline: Effects on Cognitive and Brain Function
This randomized study tests whether a new multicomponent Positive Psychology program can improve cognition and wellbeing in older adults at the earliest stages of dementia-related decline. About 128 participants with Subjective Cognitive Decline or Mild Cognitive Impairment will be enrolled. Half will be randomized to the Positive Psychology program and …
Clinical Trial on Agitation in Alzheimer's Dementia
The purpose of this study is to assess the efficacy of the oral medication IGC-AD1, a THC-based (Delta-9-Tetrahydrocannabinol) formulation administered twice a day on Agitation in patients with mild to severe dementia from Alzheimer's.
Chronic Treatment of Alzheimer's Disease by Gamma Light and Sound Therapy
Alzheimer's disease (AD) is characterized by significant memory loss, toxic protein deposits amyloid and tau) in the brain, and changes in the gamma frequency band on EEG. The investigator's lab found that boosting gamma waves in AD mouse models using light and sound stimulation at 40Hz not only reduced amyloid …
Selective PET Imaging of Astrocytes and Microglia in Alzheimer's Disease
Inflammation occurs in many brain diseases including Alzheimer's disease. In Alzheimer's disease, an abnormal protein called amyloid starts accumulating decades before the start of forgetfulness. However, scientists have reported that inflammation but not amyloid is linked to forgetfulness and the topography of brain inflammation and tau buildup are closely correlated …
The Role of the Locus Coeruleus in Age-related Distractibility
A growing body of research has highlighted the importance of frontal regions, at both the functional and structural levels, in age-related declines in attentional and cognitive processing. However, the underlying neurobiological pathophysiological changes in the brain that contribute to these declines are still largely unclear. The objective of this proposal …
MR Evaluation of Cerebrospinal Fluid (CSF) Dynamics
The Researchers are trying to test a MR imaging method for detection of Cerebral Spinal Fluid (CSF) flow in the brain to help diagnosis and better understand diseases that affect brain function.
Sleep Trial to Prevent Alzheimer's Disease
The purpose of this study is to determine if treatment with the sleep aid suvorexant can decrease the rate of amyloid-β (Aβ) accumulation in the brain.
Gamma Light and Sound Stimulation to Prevent Dementia in Cognitively Normal People At Risk for Alzheimer's Disease
Alzheimer's disease (AD) is characterized by significant memory loss, toxic protein deposits (amyloid and tau) in the brain, and changes in the gamma frequency band on EEG. Gamma waves are important for memory, and in patients with AD, there are fewer gamma waves in the brain. The Tsai lab found …
