Abstract:
The article presents modern approaches to the early diagnosis of AD. The aim of the study was to compare clinical and laboratory
data in the early diagnosis of AD. Laboratory tests were carried out using the enzyme immunoassay determination of the level of
DHEA-S before and after the oxidation of the catalyst with Fe2+. When studying the DHEA level in blood serum before and after oxidation
with a catalyst, the level of DHEA was insignificant or absent in patients with AD, while the level of DHEA in patients without AD
increased sharply. The new diagnostic method proposed by us showed a differential diagnosis of AD.
