'Brain training' may lessen cognitive impairments associated with coronary bypass surgery
Date:9/17/2012

hether training aimed at a specific function would lead to benefits for other non-targeted functions. Through regular follow-up over six months, the researchers measured progress in 44 patients over the age of 65 who were chosen based on whether they were in good physical and mental health before the surgery.

The study suggests that the development of cognitive rehabilitation tools would be highly beneficial for patients who undergo coronary bypass surgery as a way to speed up their recovery and improve their quality of life.

Research summary

The day before their surgery, participants took a number of neuropsychological tests to measure their cognitive functions, including verbal fluency, short-term and delayed memory, interference effect, psychomotor speed, sustained and selective attention, ability to multitask, etc. The subjects were then divided into three groups for the study. The control group subjects did not undergo any cognitive training after their operations. The second group received memory training followed by training that aimed to improve attention level. Finally, the third group received attention training followed by memory training. The patients retook the neuropsychological tests 3 to 7 days after their surgeries as well as 1 month later to measure cognitive losses. After the testing, 65% of them showed a cognitive deficit after 1 week, a deficit that was still present for 41% of them after 1 month. Between the 6th and 10th week after the surgery, patients had 4 sessions of cognitive training 2 times per week. The patients then took various cognitive tests again at 3 months and 6 months.
