The present disclosure is based on the identification of biomarkers of combined genetic variants and imaging measurements, in predicting faster decline in cognitive measures and brain glucose metabolism in populations with Alzheimer's disease or those susceptible to developing Alzheimer's disease. The present disclosure provides a method of treating a patient with Alzheimer's disease (AD) or a subject susceptible to developing AD, comprising: (a) assaying a sample obtained from an early-stage AD patient or a subject susceptible to developing AD for the presence of a brain-derived neurotrophic factor (BDNF) gene mutation and / or a protein tyrosine phosphatase receptor-type, Z polypeptide 1 (Ptprz1) gene mutation; (b) determining whether the patient or subject is positive for brain amyloid-beta (Aβ), wherein the presence of brain Aβ in combination with the BDNF gene and / or Ptprz1 gene mutation correlates with a prediction of rapid cognitive decline; and (c) treating the patient or subject with early and aggressive therapy appropriate to treat AD with rapid cognitive decline.

The present invention relates to a method for predicting neurodegenerative decline and / or its severity for a patient, especially of cognitive impairment (CI). Strokes and Parkinson's disease are frequently associated with occurrence of long-term cognitive impairment or dementia with still incompletely resolved mechanisms. The discovery of diagnostic and predictive biomarkers thus remains a major challenge. The method of the invention uses radiomics corresponding to texture features extracted from a plurality of previously-acquired medical brain images and correlated with previously-acquired clinical and / or biological data. A classifier is trained beforehand for learning these radiomics, and then operated on radiomics computed from at least one brain image of a patient to generate a score representative of its risks of neurodegenerative decline. By applying this method on a cohort of 160 MCI and non-MCI patients, the inventors show that MCI patients could be early predicted with a mean accuracy of 88%. In the same way, the method was able to discriminate very early stages of cognitive decline in a Parkinson's disease population of 100 patients.

The present invention pertains to novel therapeutic ways for treating cognitive disorders associated with olfactory dysfunction. By using a mouse model of Down syndrome (DS—Ts65Dn mice), the present inventors have demonstrated that GnRH insufficiency is involved in the age-dependent acquisition of cognitive decline in DS and that pulsatile GnRH treatment allows reversing olfactory- and cognitive-associated impairments in DS. The present inventors have further demonstrated that GnRH insufficiency is involved in the pathological pathways of cognitive disorders in which the cognitive decline is associated with olfactory dysfunction, and, accordingly, that pulsatile GnRH administration can be used for the treatment of cognitive disorders associated with olfactory dysfunction. Accordingly, the present invention pertains to the use of GnRH for the treatment of cognitive disorders, said GnRH being administered by pulsatile administration. The present invention further pertains to a miR-200 and / or a miR-155, which are known to be involved in GnRH-secretion regulation, for use in the treatment of cognitive disorders.
