Accumulating research documents typical rates in the range of 85% of mild traumatic brain injury (MTBI) showing prompt, complete resolution with 15% suffering from persistent neurobehavioral impairments. Studies of neurobehavioral symptoms of MTBI have not separated these two populations, resulting in either inconclusive or contradictory conclusions(More)

Recent research supports the need for consideration of neuropsychological base rate phenomena in personal injury claimants. This response describes the utility of a preinjury versus postinjury procedure for alleviating possible false positive errors in postinjury behavioral symptoms, while concurrently minimizing likelihood of false negative errors.
The recent report on neuropsychological testing of the Therapeutics and Technology Assessment Subcommittee of the American Academy of Neurology (AAN) has implications for neuropsychologists as well as neurologists. The subcommittee's report omits mention of standardized neuropsychological test batteries used by a majority of practicing neuropsychologists,(More)
A prospective study of pseudoseizures using prolonged video-electroencephalographic (EEG) recording was carried out in 60 patients. Of 33 patients with episodes of uncertain mechanism, a diagnosis based on recorded episodes was made in 18 (55%). Twelve (36%) had pseudoseizures; 6 (18%) had epileptic seizures. Ten additional patients had epileptiform EEGs(More)
This paper reports the results of a survey of current members of the American Psychological Association's Division of Clinical Neuropsychology and the National Academy of Neuropsychologists on issues regarding practice. Data were compared between groups and to the findings of two 1980 surveys. Specifically, respondents were asked to include their employment(More)
