Evidence-based cognitive rehabilitation after acquired brain injury: A systematic review of content of treatment

Evidence-based cognitive rehabilitation after acquired brain injury: A systematic review of content of treatment

"......We reviewed all randomised trials on cognitive rehabilitation in order to determine the effective elements in terms of patients' and treatment characteristics, treatment goals and outcome. .....Most studies had been conducted on language (n = 25), visuospatial functioning (n = 24), and memory (n = 14). Stroke patients were the commonest subjects (57%; overall mean age = 52.2, SD = 15.0 years). ..... With 95 RCTs there is a large body of evidence to support the efficacy of cognitive rehabilitation, and the current study can serve as a database for clinicians and researchers. But most studies have given little information about the actual content of the treatment which makes it difficult to use the studies when making treatment decisions in daily clinical practice. We suggest developing an international checklist to make standardised description of non-pharmacological complex interventions possible...."

If you found yourself feeling a little woozy while watching 3-D films like "Avatar" or "Tron," you won't be surprised to hear this. More than half the people who put on the special glasses and caught a showing of a 3-D flick reported the movie made them feel sick to some degree, a new study suggests.
Roughly 55 percent of viewers had at least one physical complaint after the experience, according to research recently published in the journal PLoS ONE...."
