winic1,

You problem sounds like it is likely manifesting as cerebral ischemia. This lack of good blood flow can cause many symptoms similar to PCS. Many with PCS have inflammation in the upper cervical vertebra than can occlude the vertebral arteries. This blocked or reduced blood flow would cause the same symptoms regardless of where the blockage or restriction is.

The word finding problems you are having will likely continue until you can increase the blood flow. Have you been examined by a vascular specialist?

I am concerned that your reduced blood flow will cumulatively slowly damage your brain. Speech rehab will likely be unsuccessful until the blood flow is corrected.

I hope you can find a doctor who will aggressively work to return your blood flow to your brain. Besides the word finding problems, I would suspect you also have nightmares or other stressful dreams. The many symptoms of poor cerebral blood flow can be very frustrating and elusive.

btw, I have believed I have had a cerebral basilar ischemia since 2001. I have been hard pressed to find a doctor who will look into this possibility. I get inflammation in the upper left area of the neck near the left occipital condyle. When this happens, that side of my head tingles and I will have stressful dreams and even central sleep apnea.

My best to you.
