"Recently, an increased interest has been shown in the potential associations between neurodegenerative diseases and rosacea. For example, a nationwide cohort study from Denmark explored the relationship between rosacea and neurodegenerative diseases such as Parkinson’s disease. MMPs are believed to be associated with the neurodegenerative diseases and an increased expression of MMP-1 and MMP-9 has also been observed in rosacea. In addition, another Danish study found that rosacea was significantly associated with dementia, especially Alzheimer disease. AMPs, MMP, and inflammatory cascades, which have a shared impact on both rosacea and Alzheimer disease, are considered to be involved in the underlying mechanism. Together, these findings suggest that a pathogenic link might therefore exist between rosacea and neurodegenerative diseases."
