Which effects can COVID-19 have on the brain? 
aka: Wearing masks and taking the vaccine are worth it if it means that you rule out the bare possibility of having any of this (or giving it to others)

TL;DR: the virus can directly invade the brain via different pathways or indirectly influence it by inflammation or affecting blood coagulation leading to blood clots that can damage the brain. 2/11
First hints that COVID could possibly affect the brain 3/11
First hints that COVID could possibly affect the brain 4/11
Cytokine storm can lead to blood brain barrier breakdown and tissue damage 5/11
COVID can affect blood coagulation possibly leading to strokes/brain hemorrhage 6/11
The virus could possibly enter the brain via e.g. olfactory bulb, broken blood brain barrier, and vagus nerve 7/11
The virus could possibly lead to neuronal death and neurodegenerative-like effects in different brain areas (e.g. involved in learning and memory or the control of breathing) 8/11
BUT most of the cognitive problems associated with COVID might be die to the inflammation and blood clots and not direct viral tissue damage. The described complications could also be observed in other infectious and inflammatory diseases before. 9/11
Additionally to the virus having effects on the body and brain, the invasiveness of ICU treatment and being exposed to long sickness can have a strong impact on mood and behavior and can possibly lead to e.g. brain fog and neuropsychiatric manifesta tions such as PTSD. 10/11
Instagram saw it first so it was prepared for Instagram, but this slide also has the references 11/11
