From my experience, I know that I know that psoriasis and psoriatic arthritis with its cousins fibromyalgia and hashimotos is that my thought processes have fundamentally changed. Psoriasis, PSA, ans hashimotos all have brain fog as a side effect. One of my worst symptoms is my loss of memory and my inability to multi-task like I’ve done my whole life.

Do other people experience severe brain deficits?

I have been told by a neuropshycologist that the inflammation of PsA occurs throughout your entire body, affecting your organs and brain as well. It can affect memory, mood, cognitive functioning etc. Another reason to get PsA inflammation controlled.
