Design outcomes

Primary

MeasureTime frame
1. The standardized score of composite memory

Secondary

MeasureTime frame
1. The standardized scores of each cognitive domain {neurocognition index (NCI), verbal memory, visual memory, psychomotor speed, reaction time, complex attention, cognitive flexibility, processing speed, executive function, social acuity, reasoning, working memory, sustained attention, simple attention and motor speed} 2. Flow mediated dilation (FMD), maximum expansion width of the blood vessel*, and the resting vessel diameter 3. Vascular age, deviation value of vascular aging, waveform index, and low frequency / high frequency ratio 4. An original questionnaire (1."Are you told that you say the same thing repeatedly by people around you?", 2."Do you often forget where you put your things such as your wallet and keys and have to look for them?", 3."Do you sometimes find it difficult to say the words that you were going to say?", 4."Do you feel decline in attention and/or concentration?", 5."Do you sometimes find it difficult to show interest in new things due to lack of motivation?", 6."Do you sometimes forget other things to do while you are doing one thing?", 7. "Can you recall recent news or events and tell it somebody", 8."Do you sometimes lose the plot of a story during a conversation?", 9."Do you feel that you become more angry and/or suspicious easily?", 10."Do you feel that you make more mistakes in daily life such as cooking, cleaning up, calculating, or driving?", 11."Do you feel that you take more time to remember new things / you cannot remember new things / you forget it immediately?", and 12."Do you often feel that you cannot recall people's names?" *Maximum expansion width of the blood vessel = the maximum dilated vessel diameter - the resting vessel diameter
