New treatment option for Amnesia
Official title OCT-Angiography and Adaptive Optics in Patients With Memory Impairment
ClinicalTrials.gov ID: NCT04389437
What this study is testing
- What it's testing
- Studies suggest an association between retinal abnormalities and NCD (Neuro Cognitive Disorders) whether they are linked to proven or prodromal Alzheimer's disease (aMCI : amnestic mild cognitive impairment), or to other neurodegenerative diseases such as frontotemporal dementia or Lewy body diseases. These retinal anomalies objectified by OCT-A (Optical coherence tomography angiography) and adaptive optics (AO) appear different depending on the pathologies and could therefore serve as markers in vivo of the pathophysiological processes underlying NCD.
