Ah, I see the merry-go-round of "no, some other specialist needs to see you first" is alive and well.

Is there any compelling evidence that psychiatric conditions causing "brain fog" actually represent a distinct underlying pathology from TBI or post-viral fatigue, or is it just assumed that they must be different because they're given different labels and handled by different medical specialties?

There's plenty of evidence the virus itself structurally impacts the brain in terms of sensory perception. Jumping to the conclusion that it is merely PTSD seems unwarranted.

Agreed, anecdotally, I have facial neuralgia (V5 nerve) following my moderate covid case. Confirmed by a Neurologist and MRI as post viral damage! Still have the pain 5 months on.

The article doesn’t state it as merely PTSD. To ignore a probable and possible cause of symptoms is unwarranted.
