Claim 8:
9. The method according to claim 8, wherein the method further comprises determining a synaptic entropy network indication parameter by recording a number of brain glucose metabolism images to form a three-dimensional representation of the brain and, for each image, calculating a partial synaptic entropy indicator as, H

where i and j represent a location of each pixel of the image, m is a number of rows, n is a number of columns, and b is a base of logarithm,
where a synaptic entropy indicator is calculated as

HT=ΣHS 

where the synaptic entropy network indication parameter is calculated by at least relating said synaptic entropy indicator to a corresponding normalized synaptic entropy indicator, where the normalized synaptic entropy indicator is calculated as an average synaptic entropy network indication parameter for at least 30 healthy subjects.
