2. Exposure History Questionnaire:
This questionnaire provides us information so that we may be able to offer a preliminary analysis of the possible brain and nervous system effects of your exposure situation. It is an important part of all of our clinical exams, consulting, and diagnostic procedures, as well as essential for forensic applications. By collating your information into this instrument, we can more readily analyze and prepare opinions regarding your health and the possible causes for health declines.

Obtaining a copy of the Exposure History Questionnaire:
Please complete this questionnaire on your computer using any word processing program, then e-mail the file to us for analysis. It is also possible, but not as preferable, to print out the file, and complete it by typewriter or handwriting. Either way, if you cannot email the file, you can either fax it to (877) 201-3456, or mail it.
For the fee of $400, we will analyze your responses and offer  a 1-2 page preliminary opinion – or a 30-minute telephone consultation. The analysis takes about 2 weeks after payment. For both the telephone consultation and the written opinion, an additional  fee of $100 applies.
