Condition: Ear, Nose and Throat / Loss of Smell
Investigator: Jonathan Overdevest, MD, PhD
Status: Currently Recruiting
The Columbia University Department of Otolaryngology is interested in understanding altered flavor perception through the Cognitive Flavor Assessment Protocol (CFAP), a novel multisensory diagnostic and training framework that links smell and taste function to cognitive and emotional health. You can participate in this study if you are an adult between 18…
Condition: Ear, Nose and Throat / Loss of Smell
Investigator: Jonathan Overdevest, MD, PhD
Status: Currently Recruiting
Our research team at Columbia University is trying to understand the impact of COVID-19 on smell and taste (chemosensory) dysfunction among adult patients from the Greater New York City area. Current areas of study include: 1) Investigation of smell and taste recovery patterns among patients with COVID-19; 2) Studies on how recovery of smell and taste after…
Condition: Psychiatric Disorders / ADD/ADHD
Investigator: Jonathan Posner, MD
Status: Closed
Children with Attention-Deficit/Hyperactivity Disorder (ADHD) are typically treated with two types of medications: stimulants and non-stimulants. These medications work in different ways to treat ADHD symptoms, but we do not fully understand the brain mechanisms underlying the medications' effects. This study will use MRI scanning to look at changes in…
Condition: Heart Disease / Carotid Artery Stenosis
Investigator: Anthony Pucillo, MD
Status: Closed
This clinical trial is for patients diagnosed with carotid artery stenosis that are at high risk of a stroke. Carotid artery stenosis develops as a result of plaque buildup in the carotid artery. Over time plaque buildup creates a narrowing of the carotid artery, restricting the flow of blood. Thus, increasing the risk of stroke. In this research study the…
Condition: Psychiatric Disorders / ADD/ADHD
Investigator: Jonathan Posner, MD
Status: Closed
In this study, we are trying to learn more about how stimulant medication produces an improvement in emotional lability (frequent mood changes and excessive emotional reactions) in patients with Attention Deficit Hyperactivity Disorder (ADHD.) Although ADHD is primarily associated with inattention, hyperactivity, and impulsivity, emotional ability plays a…
