Research Lab Results for dementia
Alzheimer's Disease Research CenterLab WebsitePrincipal Investigator:
Marilyn Albert, Ph.D.
The goal of the Johns Hopkins Alzheimer's Disease Research Center (ADRC) is to accelerate the d...iscovery of new treatments that are directed at the basic mechanisms of disease, and to hasten the time when effective treatments for AD and related disorders become a reality. We have a strong commitment to basic research regarding the underlying mechanisms of Alzheimer's Disease and related disorders, and how this may translate into effective treatment. We perform clinical research seeking to identify medications to delay or treat the symptoms of dementia. We also provided many educational programs for family members and professionals. view moreResearch Areas: dementia, Alzheimer's disease
Healthy Brain ProgramLab WebsitePrincipal Investigator:
Leah Rubin, Ph.D., M.A., M.P.H.
Psychiatry and Behavioral Sciences
The Brain Health Program is a multidisciplinary team of faculty from the departments of neurolo...gy, psychiatry, epidemiology, and radiology lead by Leah Rubin and Jennifer Coughlin. In the hope of revealing new directions for therapies, the group studies molecular biomarkers identified from tissue and brain imaging that are associated with memory problems related to HIV infection, aging, dementia, mental illness and traumatic brain injury. The team seeks to advance policies and practices to optimize brain health in vulnerable populations while destigmatizing these brain disorders.Research Areas: HIV infection, mental illness, aging, traumatic brain injury, dementia
Current and future projects include research on: the roles of the stress response, glucocorticoids, and inflammation in conditions that affect memory and the related factors that make people protected or or vulnerable to memory decline; new mobile apps that use iPads to improve our detection of memory deficits; clinical trials looking at short-term effects of low dose hydrocortisone and randomized to 28 days of treatment; imaging brain injury and repair in NFL players to guide players and the game; and the role of inflammation in memory deterioration in healthy aging, patients with HIV, and other neurodegenerative conditions. view more
JHU NIMH Research CenterLab WebsitePrincipal Investigator:
Justin McArthur, M.B.B.S., M.P.H.
The Johns Hopkins NIMH Center is comprised of an interdisciplinary research team who has pooled... their talents to study the nature of HIV-associated neurocognitive disorders (HAND). Their aim is to translate discoveries of the pathophysiological mechanisms into novel therapeutics for HAND.Our objectives are to integrate aspects of ongoing research in HAND and SIV encephalitis; to develop high-throughput and screening assays for identifying novel therapeutic compounds; to use proteomics and lipidomics approaches to indentifying surrogate markers of disease activity; to disseminate information and education about HAND through existing and new educational systems, including the JHU AIDS Education Training Center and the JHU Center for Global Clinical Education and to facilitate the entry of new investigators into neuro-AIDS research, and to catalyze new areas of research, particularly where relevant for drug discovery or the development of validated surrogate markers. view moreResearch Areas: neuropathy, HAND, AIDS dementia complex, myopathy, myelopathy, HIV-associated neurocognitive disorders
Sevil Yasar LabPrincipal Investigator:
Sevil Yasar, M.D., Ph.D.
Research areas in the Sevil Yasar Lab include dementia, cognitive decline, hydrocephalus and ph...armacoepidemiology. Recently, we studied the ability of fatty acid amide hydrolase (FAAH) inhibitors to block the rewarding effects of nicotine in squirrel monkeys. view moreResearch Areas: cognition, epidemiology, pharmacoepidemiology, dementia, gerontology, hydrocephalus
The Sun LaboratoryLab WebsitePrincipal Investigator:
Shuying Sun, Ph.D.
The nervous system has extremely complex RNA processing regulation. Dysfunction of RNA metaboli...sm has emerged to play crucial roles in multiple neurological diseases. Mutations and pathologies of several RNA-binding proteins are found to be associated with neurodegeneration in both amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). An alternative RNA-mediated toxicity arises from microsatellite repeat instability in the human genome. The expanded repeat-containing RNAs could potentially induce neuron toxicity by disrupting protein and RNA homeostasis through various mechanisms.Research Areas: ALS, neurodegeneration, RNA
The Sun Lab is interested in deciphering the RNA processing pathways altered by the ALS-causative mutants to uncover the mechanisms of toxicity and molecular basis of cell type-selective vulnerability. Another major focus of the group is to identify small molecule and genetic inhibitors of neuron toxic factors using various high-throughput screening platforms. Finally, we are also highly interested in developing novel CRISPR technique-based therapeutic strategies. We seek to translate the mechanistic findings at molecular level to therapeutic target development to advance treatment options against neurodegenerative diseases. view more
