Experimental: Huperzine A
Huperzine A will be administered to patients, titrating dose up from 100mcg/day to 600mcg per day over the course of 20 days - and remaining on the dose of 600mcg/day for the remainder of the drug phase (64 days) - for a total of 12 weeks on Huperzine A.
Drug: Huperzine A
Huperzine A will be administered for 12 weeks as outlined in the Arm Description
Placebo Comparator: Placebo
Placebo will be administered to patients at the same frequency/intervals as the experimental arm (Huperzine-A).
Placebo Arm (blinded randomization) for Huperzine A Intervention
- Change in Cognition (learning and memory)from baseline [ Time Frame: Measured for approximately one year ]To determine whether Huperzine A, as compared to placebo, has a differential effect on learning and memory functions after moderate to severe TBI, as measured by the California Verbal Learning Test- II (CVLT-II). This CVLT-II will be measured at baseline, 6 weeks, 12 weeks and at 52 weeks.
- Changes in neurophysiological markers (EEG and TMS)from baseline [ Time Frame: Measured for approximately one year ]To determine whether administration of Huperzine A produces significant differences in neurophysiologic markers (as indexed by EEG event related potentials (P50 and P300) and TMS-indexed cortical excitability (cholinergic activity)) associated with cognition relative to a placebo. This will be measured at baseline, 6 weeks, 12 weeks, 24 weeks and 52 weeks.
- Changes in seizure activity from baseline [ Time Frame: Measured for approximately 12 weeks ]To determine whether Huperzine A reduces the prevalence/frequency of post-traumatic seizures after moderate and severe TBI as compared to placebo at 12 weeks post-enrollment (immediate seizures prevalence). Seizures will be continually monitored through the study.
- Safety of Huperzine-A [ Time Frame: Measured for approximately one year ]To evaluate the safety and tolerability of Huperzine A in this patient population as compared to placebo. Safety and tolerability will be assessed by a comparison of the frequency and intensity of adverse effects, as measured throughout the study participation.
