The invention provides an application of a ratio of neutrophil to lymphocyte in preparation or screening of a cognitive disorder risk diagnostic reagent. It is found that in APOE epsilon 4 allele carriers, increase of the NLR level is related to the high onset risk of cognitive impairment of the APOE epsilon 4 allele carriers, meanwhile, obesity further increases the dementia occurrence risk of high-inflammation people, and new evidence is possibly provided for synergistically promoting dementia occurrence through metabolic disorders and peripheral inflammation. In non-APOE epsilon 4 allele carriers, the high NLR level does not increase the cognitive impairment occurrence risk of old people, and it can be seen that the influence of inflammation on cognition may be an important factor for impairment of the cognitive function of the APOE epsilon 4 allele carriers. Based on an ADNI database, it is proved through longitudinal research that peripheral inflammation plays an important role in gradual decline of the cognitive function of an APOE epsilon 4 gene carrier, the high NLR level is related to fast cognitive decline, and deposition of Alzheimer's disease neuropathology markers is promoted faster. On the other hand, the AD core pathological marker plays an important role in regulating the NLR level and cognition.

The present invention relates to the field of treat age-related cognitive declines. In this study, the inventors report that GPR158, which localizes at the PC, is required for OCN- dependent autophagy induction in hippocampal neurons. Consistently, the mobilization of key autophagy players by OCN in hippocampal neurons requires core PC-proteins. In aged hippocampi, neuronal PC present an abnormal morphology, correlated with a reduction of the major core ciliary proteins levels. Conversely, restoration of their levels in aged hippocampi is sufficient to improve autophagy and cognitive deficits. Lastly, they show that core PC-proteins are required to integrate the rejuvenating effects of OCN in the hippocampus, thereby ameliorating age-related cognitive deficits. Altogether, these findings demonstrate a new paradigm for the neuron / systemic milieu communication and significantly advance our understanding of the regulatory mechanism mediating the rejuvenating effects of the pro-youth blood factor, OCN, in hippocampal neurons. This study also provides the foundation for novel therapeutic strategies to treat age-related cognitive decline, as well as neurological deficits in ciliopathies. Thus, the present invention relates to an activator of the primary cilia (PC) for use in the restoration and / or improvement of cognitive functions in a subject in need thereof.
