I found these articles interesting on two levels: the implications for after-effects of today's COVID-19 infections, and from the historical viewpoint of some of the extreme after-effects of the 'Spanish Flu', like th Sleeping Sickness, and the actual potential source of cases that are currently being post-diagnosed as PTSD.

How coronavirus affects the brain

When it comes to the brain and nerves, the virus appears to have four main sets of effects:

  1. A confused state (known as delirium or encephalopathy), sometimes with psychosis and memory disturbance.
  2. Inflammation of the brain (known as encephalitis). This includes a form showing inflammatory lesions – acute disseminated encephalomyelitis (ADEM) – together with the effects of low oxygen in the brain.
  3. Blood clots, leading to stroke (including in younger patients).
  4. Potential damage to the nerves in the body, causing pain and numbness (for example in the form of post-infectious Guillain-Barre syndrome, in which your body’s immune system attacks your nerves).

Scientists warn of potential wave of COVID-linked brain damage

LONDON (Reuters) - Scientists warned on Wednesday of a potential wave of coronavirus-related brain damage as new evidence suggested COVID-19 can lead to severe neurological complications, including inflammation, psychosis and delirium.
A study by researchers at University College London (UCL)described 43 cases of patients with COVID-19 who suffered either temporary brain dysfunction, strokes, nerve damage or other serious brain effects.
In the UCL study, published in the journal Brain, nine patients who had brain inflammation were diagnosed with a rare condition called acute disseminated encephalomyelitis (ADEM) which is more usually seen in children and can be triggered by viral infections

Remains to be seen’ if coronavirus causes same brain damage as Spanish flu

It is increasingly coming to light that a relatively small group of coronavirus patients endure neurological complications, like strokes or delirium.
