Rosey cheeks a dementia risk

A new study concludes that rosy cheeks may not be the sign of hearty good health we thought it was - in fact, it may be an indicator of increased dementia risk in later life.

dollsheadThe findings, published in the Annals of Neurology, a journal of the American Neurological Association and Child Neurology Society, demonstrated a link between sufferers of the common chronic inflammatory skin disorder particularly with an increased risk of Alzheimer’s disease.

Rosacea is charaterised by elevated expression of certain proteins that are involved in various neurodegenerative disorders.

Individuals presenting with rosacea among the Danish population were tracked between 1997 and 2012. A total of 99,040 individuals developed some form of dementia in that time, representing an increased risk of about 7 per cent, after adjustments for confounding factors.
