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…
The study uses brain imaging and cortisol to understand risk and protective factors for mental health among adolescents on social media. We are currently recruiting adolescents ages 14-17 who struggle with mental health. To participate in our study, we would ask your child to: 1. Complete a mental health interview (over Zoom), 2. Complete a Magnetic…
We are studying the natural course of autoimmune hemolytic anemia (AIHA). If you are an adult between 18 and 120 years old, receive care at Columbia University Irving Medical Center-New York Presbyterian Hospital, are willing to provide a blood sample every 6 months for research, and have one of the following diagnoses: AIHA,…
This research study aims to obtain a greater understanding of the causes of cognitive decline in Alzheimer's disease. We are currently enrolling male and female participants (ages 55 years and older) with Alzheimer's disease, mild cognitive impairment, or healthy controls. Enrolled participants with undergo a small blood draw…
The purpose of this study is to identify genetic causes of lung diseases and to develop a research repository so that we can better understand, prevent and treat these conditions. You should consider joining this study if you have been diagnosed with a lung disease that has a genetic cause or if other family members have been diagnosed with a similar lung…
The purpose of this study is to identify genetic causes of lung diseases and to develop a research repository so that we can better understand, prevent and treat these conditions. You have been asked to join this study as a healthy control. Even though you do not have lung disease, your sample is valuable to us. For example, you may be related to someone…
This research is being done to determine how variations in genes may explain the different risk to develop scleroderma (or CREST) seen in African American patients compared to other populations. People who are African American with scleroderma (or CREST) may join. This research involves a blood draw and physical exams.
MS Genetics aims to better understand the genetic component of demyelinating diseases by doing genetic testing on blood samples of participants. This study involves a one-time blood draw and completion of questionnaires spread out over a couple of years in hopes to better understand the genes…
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…
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 nationwide study.…
Lymphangioleiomyomatosis (LAM) is a rare lung disease primarily affecting young women. Currently, LAM is often diagnosed in patients with radiology imaging (CTs) and/or lung biopsies; however, these methods can be imprecise, invasive, and/or can carry significant risks. The current study aims to devise a less invasive tool for diagnosis of this rare…
We will enroll children with severe early onset obesity (BMI greater than 99th percentile) diagnosed prior to 6 years of age or other endocrine disorders. We will ask questions about their health, eating behavior and perform a brief physical examination. We will collect saliva or blood to perform…
Genes and Environment in MS (GEMS) is a longitudinal cohort study investigating how genetics and environment can lead to the onset of Multiple Sclerosis. We are recruiting first-degree relatives (siblings, parents, and children) of people who have been diagnosed with MS. This study involves the collection of magnetic resonance imaging (MRI) of the brain,…
We are looking for participants for a study on the role of immune response in Parkinsons disease (PD) and Alzheimer's disease (AD). We are inviting people WITH PD, WITH AD, WITH amnestic Mild Cognitive Impairment or WITHOUT PD or AD to come and participate. We will be doing several questionnaires, a motor exam, and a short cognitive assessment, in addition…

The purpose of this study is to determine how inflammation is related to changes in the brain that occur during the progression of Alzheimer's disease. If you are eligible for this study, we will ask you to complete 3-4 study visits over the course of about 5 months. Participation includes memory testing, a blood draw, MRI,…
Growth hormone and insulin-like growth-factor 1 (IGF-1) are two hormones that are very important to human growth and metabolism. In disorders of GH and IGF-1 excess and deficiency, significant growth and metabolic abnormalities can develop. This study investigates the effects of GH on the appetite-stimulating hormone AgRP (…
This study aims to find genes that cause Alzheimer's Disease in African Americans and Hispanics/Latinos. Participants are eligible if African American or Hispanic/Latino and 60 years of age or older. Study participation would entail completing a memory assessment, having their blood drawn, and a brief physical exam with a…
The Snapshot study aims to understand brain and spinal cord aging in healthy individuals and individuals with multiple sclerosis (MS). We aim to identify new tools that will help us to achieve successful brain aging in the general population and in people with an underlying autoimmune disease. A critical aspect of this study is that we are looking for…
