Effects of Brain Training Games on Cognitive Function and Quality of Life in MCI

Montreal Cognitive Assessment Scale

Brief cognitive function assessment is done using MoCA Questionnaire which consist of 12 items, that is to say visuospatial, executive functioning, short-term memory, attention or concentration, working memory, language, and lastly orientation. The total score of this Questionnaire is 30. As per grading system, the score of 26 to 30 represent normal cognition, score of 18 to 25 denotes mild cognitive impairment and score of 10-17 signifies moderate cognitive impairment. Lastly, score of less than 10 embodies severe cognitive impairment. The inter-rater reliability or ICC value is 0.96 (95% CI: 0.91-0.98). Cronbach's alpha is 0.79 and AUC of 0.89 (95% CI: 0.83-0.95).

Time frame: 6 weeks

Trail Making Test A and B

Trail making test is a brief paper and pencil test used to screen for any cognitive impairment with the test scored by how long does it takes for a person to complete it. In part A of the test, the patient draw lines to join numbered circles from 1-to 25, connecting them in ascending order. The average score for completing this test is 29 seconds, whereas the rule of thumb suggests a typical score of 90 seconds. A score of greater than 78 seconds indicates deficiency. In part B of the test, the patient connect the circles alternating between numbers from 1 to 13 and letters from A to L. The average score is 75 seconds, with score of greater than 273 seconds representing deficiency. The rule of thumb for this test is a typical score of 3 minutes. The retest reliability for part A is between 0.76 and 0.89 and for part B it lies between 0.86 and 0.94. The Cronbach's alpha for this neuropsychological test is 0.90.
