The objective of the current study was to determine the efficacy of amantadine in improving cognitive and behavioural performance in a traumatic brain injury (TBI) rehabilitation sample. The design was a prospective, randomized, double-blind, placebo-controlled, crossover design. Subjects were 10 adult traumatic brain injury patients in an acute brain injury rehabilitation unit. Subjects received a 2-week trail of amantadine or placebo, followed by a 2-week washout, then a 2-week trail of the alternative (placebo or amantadine). Neuropsychological outcome measures included orientation, attention, executive function, memory, orientation, behaviour, and a composite variable. Results of repeated measures ANOVA and regression analysis of slope/change showed a main effect of time, but no significant difference for amantadine versus placebo. In conclusion, although patients generally improved, this initial exploratory study found no differences in rate of cognitive improvement between subjects given amantadine versus those given placebo. However, the small sample size, heterogeneous population, acute time course, and large number of dependent variables limit power and generalizability. Implications are discussed for further research to better answer questions regarding efficacy of amantadine post-TBI.
SAH patients receiving inpatient rehabilitation make functional gains, although the rate of gain is less than for TBI or stroke. These SAH patients represent a subgroup with more severe SAH at onset than the total population of SAH survivors. The presence of hydrocephalus negatively impacts on outcome. Further detailed study of functional and neuropsychological outcome in SAH survivors is needed.
Objective: To determine the functional outcome following acute rehabilitation of patients with severe and very severe stroke using the Functional Independence Measure (FIM). Background: Most patients with severe and very severe stroke are reported in the literature to have a poor functional outcome. However, there are few studies that specifically address severity and their conclusions are confounding. Methods: We retrospectively reviewed charts of 41 consecutive patients with the primary diagnosis of ischemic or hemorrhagic stroke admitted to an inpatient rehabilitation unit with a admission FIM score of <60. Outcome measures included discharge residence, length of stay, and FIM score. Results: Over 63 percent (26 patients) were discharged to home. Discharge mean FIM scores (61.24) were significantly improved over the admission mean FIM (34.12) for self-care, mobility, communication, and social cognition. The FIM Efficiency score was 0.356/day (mean[FIMdis-FIMadm]/mean LOS) as compared with previous reports of FIM Efficiency of 0.97/day for all stroke. Conclusion: Patients with severe stroke can experience improvement during inpatient rehabilitation and be discharged to a home setting, although the rate of improvement is less than that of more moderate stroke.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
