  • Publication number: 20240329056
    Abstract: A method of assaying for the presence of Alzheimer's disease (AD) in a living human subject using a serum or plasma sample preparation from that human subject is disclosed. In one aspect, the presence of an about 90 kDa filamin A (FLNA) polypeptide fragment in a sample preparation indicates that the sample donor likely had AD. More preferably, a ratio of the amount of that about 90 kDa FLNA polypeptide fragment to the amount of full length (about 280 kDa) FLNA protein in the sample preparation is determined. If that ratio is about 10 to about 2000, the donor likely had AD, whereas if that ratio is about 0.005 to about 5, the donor likely did not have AD. A method for determining the treatment prognosis of a living human subject presumed to have Alzheimer's disease (AD), a system and kit for carrying out the assays are also contemplated.
