Neuro Psych Assessments can vary widely in cost and time. Some NPA's are only a hour or two. Others are 8 to 16 hours over a few days. A minimal NPA will cost about $800 or more. They can cost $4000 or more. The reports are usually completed over the next month. A very abbreviated NPA may have results sooner.

You insurance company will likely baulk at approving such expensive testing. They will likely want a more definitive reason for the referral. Your doctor should be able to perform an MMSE (Mini Mental Status Exam) in her office to get a basic understanding of your functions.

Interesting use of buspar. I have never heard of buspar or other anti-anxiety drugs being used to relieve anxiety caused by sound triggers. For most of us, reducing the sound exposure is the solution.

Regarding your struggles to focus, what have you tried to help with focus ? have you tried reducing background sounds ? Have you tried using headphones to watch TV or computer videos ? I doubt an NPA will be effective at identifying your focus issues. I've had 3 NPA's and discussed focus issues with the psychologist. Most are clueless about PCS caused focus issues. One even commented negatively in his report about my complaints trying to focus because of visual and auditory distractions. He made it sound like it was all made up or 'in my head.'

Your insurance company may be willing to pay for an MMSE. Neuros, psychologists and others can do them. You might benefit from inquiring about doctors who have expertise with PCS and MMSE testing.
