Abstract: An Artificial intelligence-based method for diagnosing Alzheimer's Disease or determining susceptibility to Alzheimer's Disease includes a step of obtaining a blood sample from a target subject (e.g., a human). The degree of methylation in one or a plurality of Alzheimer indicators genes is identified for leukocytes in the blood sample. Each Alzheimer indicator gene is identified as being an indicator of the presence of or risk of developing Alzheimer's Disease. Characteristically, the at least one or the plurality of Alzheimer indicators genes have been identified by a machine learning technique or by logistic regression. Finally, the target subject is identified as being at risk for Alzheimer's Disease if the amount of methylation of one or more Alzheimer indicators genes differs from the amount of methylation established in control subjects (for the same genes) not having Alzheimer's Disease by a predetermined amount.

Abstract: Provided are a method of diagnosing Alzheimer's disease using a giant magnetoresistance sensor and a magnetic bead-polyprotein complex for diagnosing Alzheimer's disease. The method of diagnosing Alzheimer's disease using the giant magnetoresistance sensor may be applied to diagnose Alzheimer's disease more easily and simply using the giant magnetoresistance sensor than using conventional fluorescent materials or genetic analyses, and the magnetic bead-polyprotein complex may be mass-produced as a diagnostic biosensor for Alzheimer's disease, and thus to be useful to monitor and treat Alzheimer's disease.

Abstract: The invention provides a method of diagnosing Alzheimer's Disease in a subject, by determining the level of at least one miRNA in a sample derived from the subject, wherein a change in the level of the at least one miRNA relative to a suitable control is indicative of Alzheimer's Disease in the subject. Methods for monitoring the course of Alzheimer's Disease, methods of treating a subject having Alzheimer's Disease, and kits for diagnosing Alzheimer's Disease are also provided.
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. Another method utilizes the differential effects of .beta.-amyloid protein on levels of the protein kinase C isoenzymes PKC.alpha. and PKC.gamma. in Alzheimer's and normal cells. Yet another method detects Eu-TTA fluorescence differences between Alzheimer's and normal cells treated with an activator of a receptor-mediated metabolic pathway. In addition a diagnostic index for improved assessment between Alzheimer's and non Alzheimer's cells is provided.
