A common skin condition, Rosacea, could be linked to an increased risk of developing dementia and Alzheimer's diseases, according to a new study led by researchers at the University of Copenhagen.

Rosacea is a skin condition affecting millions of people worldwide. The American Academy of Dermatologists defines it as a common skin disease beginning with frequent facial redness that usually begins on the nose and cheeks, but can eventually spread to the forehead and chin, writes Nature World News. An estimated 16 million Americans are affected by the skin condition, according National Rosacea Society.

A team of researchers, led by Dr. Alexander Egeberg from the University of Copenhagen, analyzed information from 5,591,718 individuals, including 82,439 patients with rosacea. The researchers found that 99,040 individuals eventually developed some form of dementia, and a further 29,193 were diagnosed with Alzheimer's disease. The risk was higher among older patients.

According to the study, patients with rosacea have elevated levels of proteins including matrix metalloproteinases (MMPs) and antimicrobial peptides (AMPs) that are also present in neurodegenerative disorders including dementia and Alzheimer's disease, writes Wandtv.

After adjusting for hazard ratios, researchers calculated that patients with rosacea had a 7 percent higher risk of developing dementia and a staggering 25 percent higher chance of being diagnosed with Alzheimer's disease compared to members of the study population that were not diagnosed with rosacea.

"While it is too early to suggest possible treatment options based on these findings, it will be interesting to see if treatment of rosacea may impact the dementia risk and vice versa," Dr. Egeberg told Medscape.com.

The authors of study cautioned that a rosacea diagnosis did not necessarily mean that sufferers would also develop a neurological disorder such as Alzheimer's or dementia.

There is no cure for the skin condition, as the cause of rosacea is yet to be established.

The study was published in the journal Annals of Neurology.
