My Comment: The idea that the brain needs rehabilitation after major surgery is not been adopted. It's routine for patient's to have physical rehabilitation after major surgery. Cognitive & memory training is an area of rapid commercial growth. Whether this will prove to have real value is uncertian. Training led to small improvements in time to respond.
Medsacpe's review of this:
The study showed that 65% of the patients showed a cognitive deficit 1 week after surgery, and 41% still showed a deficit 1 month after surgery. However, those who received cognitive training showed significant improvement in performance compared with the control group.
For example, in an assessment of reaction time at 6 months, the mean time for a dual task in the control group was 2108 milliseconds, compared with 1836 for the attention-memory group and 1706 for the memory-attention group.
Cognitive deficits are frequent after coronary artery bypass graft surgery (CABG) in the elderly population. In fact, memory and attention deficits can persist several months after the surgery. Recent studies with healthy older adults have shown that memory and attention can be improved through cognitive training programs. The present study examined whether memory training (method of loci and story generation) and attentional training (dual-task computerized training) could improve cognitive functions in patients aged 65 years and older who underwent CABG surgery. Participants (n = 51) were assigned to one of three groups: (1) control group (tested at 1, 3 and 6 months after the surgery), (2) attention training followed by memory training, (3) memory training followed by attention training (groups 2 and 3: tested at 1, 2, 3 and 6 months after the surgery). The trainings took place between the 6th and 10th week following the surgery. The three groups were compared before and after each training program using attention and memory tests and neuropsychological tests. The results showed that attention and memory trainings lead to significant improvement in the cognitive domain that was trained. It thus seems that cognitive training can be a promising tool to enhance cognitive functions after a CABG surgery.
