Diagnostic method for Alzheimer's disease
First Claim
1. A method for assaying a sample of viable cells from a patient for the presence of Alzheimer'"'"'s disease, said method comprising the steps of:
- i) assaying said sample with a bombesin Alzheimer'"'"'s disease diagnostic test, wherein a score of 0 indicates the absence of Alzheimer'"'"'s disease and a score of −
0.5 or −
1.0 indicates the presence of Alzheimer'"'"'s disease;
ii) assaying said sample with a bombesin Alzheimer'"'"'s disease diagnostic test, wherein a score of 0 indicates the absence of Alzheimer'"'"'s disease and a score of −
0.5 or −
1.0 indicates the presence of Alzheimer'"'"'s disease; and
iii) adding the scores obtained from said bradykinin and a bombesin Alzheimer'"'"'s disease diagnostic tests, wherein a negative value indicates the presence of Alzheimer'"'"'s disease and a positive value indicates the absence of Alzheimer'"'"'s disease.

Abstract
The present invention provides methods for the diagnosis of Alzheimer'"'"'s disease using human cells. Specifically, one method detects differences between potassium channels in cells from Alzheimer'"'"'s patient and normal donors, and differences in intracellular calcium concentrations between Alzheimer'"'"'s and normal cells in response to chemicals known to increase intracellular calcium levels. Other methods detect differences between the memory associated GTP binding Cp20 protein levels between Alzheimer'"'"'s and normal cells. In addition a diagnostic index for improved assessment between Alzheimer'"'"'s and non Alzheimer'"'"'s cells is provided.
