Showing the significance of the MOCA variable in the multiple regression analysis after substituting the MOCA score with single domains, sub-domains and composite domains to illustrate the components that have been most influential. In the majority of cases the number of groups that have been used in the analysis is less than the maximum possible number to avoid groups with very small or zero numbers. For example the visualspatial/executive domain can be scored from 0 to 5 making 6 possible groups, however only 2 subjects scored 2 or less. They were grouped together with a score of 3 or less and the following 3 groups were used in the analysis, 3 or less, 4 or 5. Nearly all of our volunteers scored full marks for orientation, this domain could not therefore be grouped for analysis.

Domain	Number of Groups	Left Supine P value	Right Supine P value
Visuospatial/Executive	3	0.213	0.230
Naming	2	0.927	0.386
Language	3	0.013	0.409
Attention	3	0.874	0.606
Abstraction	2	0.053	0.573
Delayed recall	4	0.013	0.085
Orientation	NA	NA	NA
Composite Executive	3	0.006	0.319
Number of F Words	Continuous variable	0.007	0.816
