Abstract:
Objective To explore the effect of computer-aided cognitive training on cognitive function and auditory event-related potential P300 in patients with vascular cognitive impairment no dementia (VCIND).Methods Sixty VCIND patients were randomly divided into two groups namely a training group and a control group,each of 30.Both groups were given routine drug treatment and the traditional rehabilitation training.At the same time,the training group was additionally given 40min computer-aided cognitive training once a day,six times a week,lasing 4 weeks.Before and after four weeks of treatment,the cognitive function,the ability of daily life (ADL) and P300 of the two groups were assessed using mini-mental state examination(MMSE),the Montreal cognitive assessment (MoCA),Barthel Index (BI) and Motor evoked potential instrument respectively.Results Before treatment,no significant difference was found in the average MoCA,MMSE and BI scores of the two groups.After treatment,improvement was observed in the total MoCA scores (22.40 ± 4.38),as well as the average score,of visual space and executive function (3.27 ± 0.58),attention (4.30 ± 1.60),language (2.67 ± 0.48),delayed memory (3.67±0.80),MMSE (22.03 ±3.55) and BI (82.17±11.28) in the training group compared with the control group.Before treatment,there was no significant difference in the P300 latency and amplitude between the two groups.After treatment,however,the P300 latency of the training group decreased to(352.1 ± 30.68) ms,significently lower than the control group [(356.45 ± 40.30) ms] and that before treatment.Meanwhile,the amplitude rose to(8.65 ± 1.18)μV,significantly higher than the control group [(8.65 ± 1.18) μV] and that before treatment.Conclusion Computer-aided cognitive training can effectively improve the cognitive function of patients with VCIND and promote their ADL.
