Covid 19 Isolation Increased Anxiety And Depression In People With Alzheimer Risk
Researchers conducted a retrospective, observational study analyzing whether COVID-19 confinement between May 8 and August 31, 2020 in Spain accelerated AD progression in 921 adults by increasing symptoms of anxiety and depression. These adults were cognitively unimpaired prior to confinement; however, a smaller subset of 254 adults exhibited pre-pandemic AD-related biomarkers. Average length of time between pre-confinement and assessment of confinement totaled 2.4 years. Pre-pandemic biomarkers included: Amyloid-beta positivity of >12 on the centiloid (CL) scale based on positron emission tomography (PET) or magnetic resonance imaging (MRI) scans MRI-based AD signature related to cortical thickness, especially in the medial temporal lobes which are vulnerable to AD Levels of known neuroinflammatory markers, especially interleukin-6 (IL-6), glial fibrillary acidic protein (GFAP), and triggering receptor expressed on myeloid cells 2 (sTREM2)...
