摘要： Methods are provided that detect cognitive impairment including mild cognitive impairment and Alzheimer disease by using a protein or its partial peptide that differs in presence or absence. Novel biomarkers are also provided for cognitive impairment and non-psychiatric disease, as well as methods for detecting cognitive impairment using such biomarkers. Specifically, a biomarker for diagnosis is provided that comprises a protein fragment or peptide of not less than 5 amino acid residues arising from at least one protein or peptide selected from the group of proteins consisting of an amino acid sequence expressed by SEQ ID NO: 1, 3, 6, 8, 10, 13, 15, 18, or 20 and selected from the group of partial peptide in these proteins consisting of an amino acid sequence expressed by SEQ ID NO: 2, 4, 5, 7, 9, 11, 12, 14, 16, 17, 19, or 21.

摘要： The present invention aims to provide methods to detect cognitive impairment including mild cognitive impairment and Alzheimer disease by using a protein or its partial peptide that differs in presence or absence, or in quantity between non-cognitive impairment and patients with cognitive impairment and further aims to present biomarkers comprising said protein and said partial peptide to be used to detect cognitive impairment including Alzheimer disease or mild cognitive impairment. Specifically, a biomarker for diagnosis of psychiatry disease or cognitive impairment comprising protein fragment or peptide of not less than 5 amino acid residues arising from at least one protein or peptide selected from the group of proteins consisting of amino acid sequence expressed by SEQ ID NOS: 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, and 25 and selected from the group of partial peptide in these proteins consisting of amino acid sequence expressed by SEQ ID NOS: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, and 27. And further aims to provide diagnostic method using these biomarker.

摘要： This invention provides a method for detecting cognitive disfunction diseases including mild cognitive impairment and Alzheimer's disease using a protein and a peptide of the protein different in the presence level in subjects having a normal cognitive function and patients suffering from cognitive disfunction diseases and a biomarker for detecting cognitive disfunction diseases including mild cognitive impairment and Alzheimer's disease containing the protein and the peptide. This invention is a biomarker for diagnosing cognitive disfunction diseases containing a prothrombin precursor protein of SEQ ID NO: 1 or a peptide THRB containing the amino acid sequence represented by SEQ ID NO: 2 which is a peptide of the protein, a diagnosis method for cognitive disfunction diseases using the biomarker, an antigen peptide represented by SEQ ID NO: 3 for creating a THRB peptide specific antibody to be used in the diagnosis method, and a cognitive disfunction disease diagnosis kit containing the THRB peptide specific antibody.
