The MMSE is very subjective. It also is rarely given as a complete test. The delayed recall is sometimes left out.

The Trail Making Test is also a good indicator. What many evaluators miss is the differential between the time for Test A and Test B. If both are in the normal range, they consider it as a normal result. What they do not do is compare the times of each test. If the subject gets a low time on Test A but a time on Test B that is near the upper limits, it indicates a problem with task shifting.

A properly administered PASAT (Paced Auditory Serial Addition Test) can be reliable. It is rarely administered per the original research.

My best and most accurate evaluation was done by a psychologist whose is not a neuro psychologist. He recognized my problems right away. The NeuroPsychs tried to deny what the scores meant.

A doctor who is both a Psychiatrist and a Neurologist was by far the worst.

Have you tried any cognitive challenges, such as complex math games or word games and worked on them until you hit a mental fatigue?

One of the rarely addressed issues of PCS is fatigue. It can take many repetitions of a task to fatigue the brain. This fatigue will become very evident once it manifests. It will require serious rest to recover.

This fatigue can even show up on the reactions tests where they hit your knee or such with the rubber mallet. It can require 12 to 20 repetitions to trigger the fatigue.

There is also the Babinski Reflex test. I have had a positive Babinski Reflex since high school. It is rare that anybody has a positive Babinski without a serious brain injury.

You also could be suffering from depression. It can make time seem to drag on forever.

Hope you can find some answers to your strange perceptions. They can really mess up your day. I know that my good days can be great. My bad days can drag on like water torture.

My best to you.
