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.
