We are conducting a research study on how psoriasis might be caused or worsened by high levels of the blood sugar-lowering hormone insulin. We are seeking people with plaque psoriasis, ages 18-65, who are overweight or obese with a body mass index of 25-35. Participants will have blood drawn and small skin biopsies taken from psoriasis plaques and nearby…
Early Age-Related Hearing Loss Investigation (EARHLI) is a study to obtain information on how a hearing aid-based intervention can prevent cognitive decline in those at risk for Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD). Age-related hearing loss (ARHL) is the third most common chronic condition in older adults. The…
We are recruiting individuals and/or families with members under the age of 65 who have dementia or are experiencing memory problems. Our initial screening can be completed in person or over the phone. The evaluation will take about 1 to 1.5 hours per person and includes a: 1. Blood sample (5 tablespoons) or saliva (1 teaspoon) collection: These blood…
For over 30 years, The Columbia University Alzheimer's Disease Research Center (ADRC) has worked with thousands of participants who have helped provide important insights into how the brain ages and why Alzheimer's disease may develop. We are actively recruiting adults 65 years of age and older who share our commitment to be part of this…
The purpose of this study is to examine the causes and pathology of alopecia areata and other hair and skin disorders. Skin biopsies and blood and/or clinical information collected in the study will be used for research aiming at developing new options for the treatment of alopecia areata and other skin and hair disorders.
Genetic studies help us to understand why some people develop certain diseases while others don't and also provide important clues about how best to treat the disease.
A significant focus of healthcare research is aimed at biomarker discoveries in brain and heart diseases in particular, and their impact on the human body in general. MRI is a key component in these healthcare services. It provides a non-invasive and non-ionizing approach to diagnose pathologies along with significant internal and external contrast…
This study is of a drug called CT1812, that is being evaluated as a possible treatment for Dementia with Lewy Bodies. In this study, which is carried out at multiple sites in the country, participants receive either CT1812 at one of two doses or placebo. The duration of the study is up to about 35 weeks. Participants receive blood tests, cerebrospinal fluid…
This is a research study for persons with memory problems that examines the utility of performing positron emission tomography (PET) scans for the brain amyloid protein found in Alzheimer's disease.
Columbia Medical Center is recruiting for a study to test whether the drug oxytocin can improve symptoms of emotion and behavior (e.g. apathy) in people with frontotemporal dementia. The study will last for up to 24 weeks (6 months). This is a crossover study, which means that each participant will receive both oxytocin and placebo (medically inactive…
Glaucoma is a given name of a group of diseases that affect the retinal ganglion cells in the eye and the optic nerve. Glaucoma cause degeneration of the retinal ganglion cells in the retina and their projections (axons) that form the optic nerve. Retinal ganglion cells and their axons transmit all of our vision information from the eye to the brain through…
This study is for patients with Glaucoma. The purpose of this study is to investigate the safety and effectiveness of a study drug called Bimatoprost Sustained Release (SR) compared to treatment with eye drug Timolol. The Bimatoprost SR is an implant that is very small, is biodegradable (dissolves naturally in the body), and contains the bimatoprost drug.
Glaucoma is the leading cause of irreversible blindness worldwide. The most important test to detect progression is visual field testing. However, this test is very subjective, often unreliable, and variable. One of the main causes of unreliable tests is the lack of attentiveness or concentration during the test. Previous studies have shown that listening…
This is a 22-week treatment, multicenter, double-blind, placebo-controlled, parallel group, Phase 2 study to evaluate the efficacy, safety, and tolerability of the study drug E2027, in participants with Dementia with Lewy Bodies (DLB) Lewy Body Dementia - LBD. The main purpose of this research study is to find if a new drug called E2027 works in people who…
