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.
