On the other hand, dementia is a condition of declining mental abilities, especially memory. Dementia can occur at any age but …
Integrating Metabolism, Connectivity, and Mesoscale Imaging at Ultra-high Field to Decipher Mechanisms of Resilience and Neurodegeneration in Neurological Diseases and Healthy Aging
The MESO7 study is a prospective observational research project designed to investigate the mechanisms of resilience and neurodegeneration in neurological diseases and healthy aging. It leverages advanced multiparametric brain and spinal cord imaging at high (3T) and ultra-high magnetic fields (7T) to assess structural, functional, metabolic, and mesoscale changes in …

Prospective observational registry for an adolescent cohort with AD under the care of a dermatology provider. Approximately 1500 subjects and 75 clinical sites in North America and select European countries will be recruited to participate with no defined upper limit for either target.
Creating a Global Research Database That Connects Genetic Information and Long-term Health Data to Improve Personalized Treatment for People With Serious Mental Illness
This observational study aims to provide new insights into the nature and classification of severe mental illness and dementias that in time should help improve diagnostic practise, and enable the development of new and improved treatments. The investigators will achieve aims by gathering information and biological samples from over 50,000 …
An Observational Retrospective Cohort Study Being Conducted in Women With Atopic Dermatitis (AD)
The objective of this study is to describe and compare the incidence of adverse pregnancy outcomes (spontaneous abortion/miscarriage, stillbirth) and prevalence of infant outcomes (major congenital malformations [MCMs], small for gestational age [SGA]) in women with AD who are treated with dupilumab during pregnancy relative to women with AD who …
Retinal Imaging in Neurodegenerative Disease
This study aims to develop and evaluate biomarkers using non-invasive optical coherence tomography (OCT) and OCT angiography (OCTA) as well as ultra-widefield (UWF) fundus photography to assess the structure and function of the retinal and choroidal microvasculature and structure in persons with mild cognitive impairment (MCI) and Alzheimer's Disease (AD), …
