New study finds brain training effective across traumatic brain injuries
Researchers from the New York University have published a study of patients with Traumatic Brain Deficits Injuries showing that in patients with mild, mild, or severe TBI with persistent cognitive problems, years after their wounds, neuroplastic computerised brain training may improve objective and subjective cognitivity measures significantly. In the brain fitness software BrainHQ from Posit Science, the researchers applied the cognitive training tasks.
In its Neurorehabilitation newspaper storey, the researchers estimate that some 5.3 million Americans today have a chronic handicap following a traumatic brain injury (TBI). Cognitive deficits are a symptom of TBIs and are likely to limit job alternatives and the capacity to function on a daily basis. The most prevalent cognitive deficiencies are processing, care and work memory speed.
The 48-person research consisted of 27 severe TBI patients, 15 intermediate TBI patients and 5 mild TBI patients. They suffered symptoms which lingered on average for more than eight years post brain injury. There were 52% male, 69% white and 44 year olds on average. They were randomised into a control and operating group that was required to conduct computerised auditory exercises for a total of 40 hours in a period of 13 weeks.
In the standard, objective measurements of verbal attention and working memory and the speed of processing have been significantly improved by the scientists. In addition, brain education participants demonstrated gains in their own cognitive capability in daily tasks, in standard subjective measurements.
"This study represents a major step forward, as it reveals benefits in both objective and self-reporting metrics," stated Posit Science CEO Dr Henry Mahncke. "So the researchers not only noticed considerable cognitive performance increases – but also that the student participants themselves saw these gains noticeably and significantly. In this way this sort of training with proper clinical guidelines will undoubtedly be mounted."
Dr. Mahncke was the lead author of last month's Brain 4 year 83-pers. Studie published in Brain journal, which showed statistically and clinically substantial improvement in total cognition compared to a video game control group, among mild patients in five military and veteran medical centre. This was the first randomised, controlled experiment on a multi-site to demonstrate a scalable procedure to address cognitive impairment caused by mild TBI, based on what four previous studies had learned.
