Montreal Cognitive Assessment (MoCA) |
MoCA version 8.1 Blind will be used to assess global cognition. The MoCA-BLIND assesses different cognitive domains such as attention and concentration, memory, language, conceptual thinking, calculations, and orientation. It contains the same items as the original MoCA except those requiring visual abilities have been removed as this is administered over the phone. Time to administer the MoCA- BLIND is approximately 5-10 minutes. The total possible score is 22 points; a score of 19 or above is considered normal. |

WMS-R: Wechsler Memory Scale-Logical Memory I & II |
Logical Memory I & II will be used to assess episodic memory. A brief story will be read to the participant who will then asked to retell it immediately (I) and after a 10- min delay filled with other activities (II). The score is the number of the 25 story units recalled immediately (I) and after the delay (II). |

Stroop Neuropsychological Screening Test (Trennerry et al., 1989) |
Stroop Test will be used to assess executive function. In Stroop C, participants are shown a list of colors printed in conflicting color ink and are asked to read words (names of colors). The second part of this task is Stroop CW in which participants are shown a list of colors printed in conflicting color ink and are asked to say the color of the ink the word is printed. The scores are the number of words named correctly in 30 seconds and the number of colors named correctly in 30 seconds subtracting the number of errors. respectively. |

Digit Span Test (Wechsler, 1987) |
Digit Span Forward & Backward will be used to assess working memory. Digit strings of increasing length will be read, and the participant is asked to repeat each string forward (Digit Span Forward) or backward (Digit Span Backward). The score is the number of correctly retrieved strings in each part. |

Word fluency Test (Welsh et al., 1994) |
Word Fluency will be used to assess executive function. The Word Fluency Test asks participants to name as many animals (part 1) or fruits and vegetables (part 2) as possible in 60 seconds. The score is the sum of the number of animals and the number of fruits and vegetables named. |

Digit Ordering Test (Cooper at al., 1991) |
Digit ordering test will be used to assess working memory. For Digit Ordering, digit strings of increasing length will be read and the participant is asked to reorder the digits and say them in ascending order. The score is the number of correctly reordered strings. |

Minutes per day of light and moderate-to-vigorous physical activity via GT3x Actigraph Accelerometer |
Device-assessed physical activity via GT3x Actigraph accelerometers will be used to assess minutes per day spent in light physical activity and moderate-to-vigorous physical activity. |

Godin-Shephard leisure-time physical activity questionnaire (GLTEQ) |
The GLTEQ is a 3-item questionnaire that assesses the number of times in the past week an individual participates in strenuous (eg, jogging), moderate (eg, brisk walking), and mild (eg, easy walking) exercise of more than 15 minutes in duration. Frequencies from the strenuous and moderate items are multiplied by 9 and 5 metabolic equivalents, respectively, and summed to calculate a moderate-to-vigorous activity score in accordance with the GLTEQ scoring protocol. |

MIND diet adherence |
Block 2005 Food Frequency Questionnaire will be used to compute MIND diet scores. Frequency of consumption for food items was assigned a score of 0, 0.5, or 1, where scores ranged from 0 (lowest adherence) to 15 (highest adherence). |
