Journal of Biomedical Engineerthe features of sMRI data，and the kernel support vector machine based data classifica-
tion algorithm was used to classify the extracted sMRI data characteristics，after ten fold cross validation evaluation，the early behavior
of Alzheimer's disease could be accurately experimental results showed that the sensitivity，specificity，accuracy and ar-
ea under the curve of the four indicators of this method were the highest，and had a better effect on early behavior recognition of Alzhei-
mer's mathod can not only effectively identify patients and normal people，but also correctly distinguish Alzheimer's dis-
ease and mild cognitive impairment patients，and the recognition effect is significant.
