[Senses and dementia : sensory loss and dementia risk].

In the course of several neurodegenerative conditions, the presence of a sensory alteration, even before the appearance of cognitive disorders or complaints concerning autonomy, can potentially lead to earlier diagnosis and more efficient management of these complex patients. The mechanisms underlying the association between sensory impairment and the risk of progression to dementia are increasingly better understood and should ultimately improve the accuracy of the diagnosis process for the most common neurodegenerative conditions, but also participate in the differential diagnosis between these conditions. Finally, early management of these sensory impairments offers a relatively easy way to modify patient's progression by delaying the onset of several symptoms during the progression towards a dementia syndrome.

Dengue and chikungunya: future threats for Northern Europe?

Arthropod-borne viral diseases are likely to be affected by the consequences of climate change with an increase in their distribution and intensity. Among these infectious diseases, chikungunya and dengue viruses are two (re)emergent arboviruses transmitted by species mosquitoes and which have recently demonstrated their capacity for rapid expansion. They most often cause mild diseases, but they can both be associated with complications and severe forms.
