Does the smell sign be the onset of dementia?

DEMENTA is a devastating diagnosis, not only for the affected person, but also for loved ones. Research continues to look for early markers of dementia in an attempt to stop it. According to a study published last year, a smelly sign is “significantly” associated with the development of dementia – do you recognize it?

Dementia describes a group of symptoms associated with the progressive decline of the brain. There is currently no cure for this condition, but research is actively investigating early markers of brain decline. The aim is to identify the mechanisms that give rise to dementia in the hope of finding ways to counteract it.

Olfactory dysfunction has been previously associated with the transition from normal cognition to dementia in people without type 2 diabetes.
