The invention relates to a method for detecting progressive, chronic dementia diseases or a predisposition to such diseases or method for the prognosis of such diseases. For this purpose, the concentration of particular peptides in body fluids or other samples from the patient is measured in a method which can be carried out in a laboratory. The invention further relates to peptides which have been found for determining the presence and/or the grade of the progressive, chronic dementia disease. The invention additionally relates to detection reagents such as antibodies and nucleic acids and the like for detecting said peptides or the corresponding nucleic acids. The invention further relates to pharmaceutical products which comprise the peptides according to the present invention, antibodies directed to said peptides, nucleic acids corresponding to said peptides, peptide antagonists, or peptide agonists for the therapy, diagnosis, prognosis or prophylaxis of neurological diseases, in particular of Alzheimer's disease. The invention further relates to methods for stratifying patients or participants in clinical studies.

L'invention concerne un procédé permettant de dépister des maladies démentielles chroniques progressives ou une prédisposition à de telles maladies, ou un procédé de pronostic de ces maladies. A cette fin, la concentration de peptides particulaires dans des fluides organiques ou d'autres échantillons prélevés chez le patient est mesurée par un procédé pouvant être réalisé en laboratoire. L'invention concerne en outre des peptides permettant de déterminer la présence et/ou le niveau de la maladie démentielle chronique progressive. Elle concerne également des réactifs de dépistage tels que des anticorps et des acides nucléiques et analogues permettant de dépister lesdits peptides ou les acides nucléiques correspondants. Elle concerne par ailleurs des produits pharmaceutiques qui comprennent lesdits peptides, des anticorps dirigés vers ces peptides, des acides nucléiques correspondant à ces peptides, des antagonistes ou des agonistes peptidiques destinés à la thérapie, au diagnostic, au pronostic ou à la prophylaxie de maladies neurologiques, en particulier la maladie d'Alzheimer. L'invention concerne enfin des procédés de classification des patients ou des participants dans des études cliniques.
