I wanted to share growing recognition that coronaviruses and other respiratory viruses can invade the Central Nervous System (Desfordes, Coupanec, Dubeau et al, 2020). While we are at an early stage of evolving understanding, the impact of COVID-19 on the brain may take several forms, via direct infection or secondary mechanisms (e.g., autoimmune response). Presence of SARS-CoV-2 RNA in patients' cerebrospinal fluid has been reported, suggestive of direct infection (Hai-Yang Wang et al, 2020).
According to this hypothesis, the route of direct brain infection with SARS-CoV-2 is as follows:
Nasal cavity > olfactory nerve > olfactory bulb > piriform cortex and brainstem (DeSantis, 2020).
Neuriomaging findings have been evident across countries, including France, UK, Turkey, China, Spain, and the United States.
High levels of cognitive and psychosocial impairment in the post-acute recovery stage of COVID-19 patients can be expected. Many will require long-term rehabilitation and innovative approaches. ReNeu Brain Center is here to diagnose and rehabilitate their neurocognitive sequelae.
Everyone can regain, retain, and renew their best life.
