Agitated behavior is frequently associated with traumatic closed head injury. Proactive behavioral intervention is often not successful, and psychopharmacologic agents may result in increasing the targeted behavior through sedation. We describe a 32-year-old woman who developed severe agitation after frontal lobe closed head injury. After failing(More)
Activators of G-protein Signaling (AGS) are a family of accessory proteins that were discovered as modulators of heterotrimeric G-protein subunits. The primary aim of the present study was to localize Group I and II AGS proteins and determine the renal expression profile using immunohistochemistry and quantitative RT-PCR, respectively, during normal and(More)
A reality orientation group for brain injured patients was developed to improve attention deficits, confusion and anterograde amnesia during post-traumatic amnesia (PTA). Seven behavioral objectives are used to define adequate orientation, attention, immediate retention, episodic recall and use of memory aids. Daily performance in each of these areas is(More)
Alteration in central nervous system function is a well-known sequela of liver failure, but has been thought to be transient after transplantation surgery. We present two cases of cerebral pontine myelinosis complicating liver transplantation. Both of these cases presented with specific post-surgical cognitive deficits assessed by neuropsychological(More)
The relationship between impairment, measured by the Halstead-Reitan Neuropsychological Test Battery (HRNTB), and disability, measured by the Functional Independence Measure (FIM), was investigated in 164 subjects completing acute, inpatient rehabilitation following traumatic brain injury. Exploratory factor analysis of the FIM supported a two-factor model(More)
Experimental tests showed that poststrike elevation in tongue-flicking rate (PETF) and strike-induced chemosensory searching (SICS) in the gila monster last longer than reported for any other lizard. Based on analysis of numbers of tongue-flicks emitted in 5-min intervals, significant PETF was detected in all intervals up to and including minutes 41-45.(More)
