SpringerLinkNeed for awareness and surveillance of long-term post-COVID neurodegenerative disorders. A position paper from the neuroCOVID‐19 task force of the European Academy of Neurology - Journal of NeurologyBackground Neuropathological and clinical studies suggest that infection with SARS-CoV-2 may increase the long-term risk of neurodegeneration. Methods We provide a narrative overview of pathological and clinical observations justifying the implementation of a surveillance program to monitor changes in the incidence of neurodegenerative disorders in the years after COVID-19. Results Autopsy studies revealed diverse changes in the brain, including loss of vascular integrity, microthromboses, gliosis, demyelination, and neuronal- and glial injury and cell death, in both unvaccinated and vaccinated individuals irrespective of the severity of COVID-19. Recent data suggest that microglia play an important role in sustained COVID-19-related inflammation, which contributes to the etiology initiating a neurodegenerative cascade, to the worsening of pre-existing neurodegenerative disease or to the acceleration of neurodegenerative processes. Histopathological data have been supported by neuroimaging, and epidemiological studies also suggested a higher risk for neurodegenerative diseases after COVID-19. Conclusions Due to the high prevalence of COVID-19 during the pandemic, healthcare systems should be aware of, and be prepared for a potential increase in the incidence of neurodegenerative diseases in the upcoming years. Strategies may include follow-up of well-described cohorts, analyses of outcomes in COVID-19-registries, nationwide surveillance programs using record-linkage of ICD-10 diagnoses, and comparing the incidence of neurodegenerative disorders in the post-pandemic periods to values of the pre-pandemic years. Awareness and active surveillance are particularly needed, because diverse clinical manifestations due to earlier SARS-CoV-2 infections may no longer be quoted as post-COVID-19 symptoms, and hence, increasing incidence of neurodegenerative pathologies at the community level may remain unnoticed.

Long #COVID Is Associated with Severe Cognitive Limitations Among U.S. Adults

"Overall, 15.1% had #longCOVID. A higher percentage of adults with long COVID (13.1% vs 4.1%) reported severe cognitive limitations compared to no COVID (p < 0.001)”

medRxiv · Long-COVID Postural Tachycardia Syndrome: A deep phenotyping studyBackground: Postural tachycardia syndrome (POTS) has emerged as one of the most common autonomic complications of Long-COVID (LC). However, disease mechanisms remain incompletely understood. Objectives: To evaluate the frequency and severity of autonomic dysfunction in a subset of carefully phenotyped, previously healthy patients with LC-POTS using a detailed protocol of autonomic, cerebrovascular, respiratory, blood, and tissue analyses. Methods: Participants in this study completed a battery of autonomic function tests, including measures of sudomotor, cardiovagal, and sympathetic adrenergic function, and head-up tilt (HUT) with transcranial Doppler measures of cerebral blood flow velocity (CBFv), end-tidal CO2 (ETCO2), cerebral and skeletal muscle near-infrared spectroscopy (NIRS) and plasma catecholamines. Skin biopsy was performed at proximal and distal sites and analyzed for intraepidermal nerve fiber density (IENFD) and phosphorylated α-synuclein (P-Syn). Results were compared to healthy controls (HC) ≥ 3 months post-COVID infection with no lasting sequelae. Results: LC-POTS participants (n=24) exhibited a greater increase in heart rate on HUT (31.1±20.3, p=0.01), and 38% exhibited elevated upright norepinephrine levels consistent with a hyperadrenergic response. CBFv did not significantly differ between LC-POTS and HC (n=10). EtCO2 and NIRS were also similar between groups. Twenty-two percent of LC-POTS and 38% of HC had decreased IENFD on skin biopsy, while 8.7% LC-POTS had dermal P-Syn aggregation on skin biopsy, compared to none of HC. Conclusions: LC-POTS was associated with widespread autonomic dysfunction, including orthostatic tachycardia, sympathetic adrenergic hyperactivity, small fiber neuropathy, and dermal P-Syn deposition. Our findings support the concept of multiple pathophysiological mechanisms in most patients with POTS triggered by SARS-CoV-2. ### Competing Interest Statement Dr. Larsen, Jannika Machnik, Jordan Seliger, and Ruba Shaik have nothing to disclose.
