Hi makingtheconnection and welcome to NeuroTalk

I honestly dont know the answers to your questions but I did want to welcome you

Hopefully someone with more knowledge in this area will be able to give you some helpful info

Sometimes there are simple answers to complex symptoms, like nutritional deficiencies that are depriving the brain and nervous systom of essential elements that they need to function correctly.
Even parasitic or chemical toxins have been known to cause a sudden change in mental capabilities etc
Also, if you are on any medications, there may be a med that you are having an adverse reaction to........my son had medication induced psychosis once and so I know that this can occur

Have you been to see a physician?
That would be the first step in finding solutions.

In the meantime, there will always be someone here to offer you support and understanding. I know it must be very scary for you to be experiencing what you are
we care
