The increase in the global number of cases of dementia is now being taken very seriously by the World Health Organisation (WHO). They have highlighted the fact that dementia is the third most onerous disease that healthcare systems face, and the fifth most common cause of death in the ageing population worldwide. Alzheimer’s disease constitutes over 50% of dementia cases, amounting to almost 6 million sufferers in Europe alone. A huge part of the WHO’s current campaign is to raise awareness of neurodegenerative diseases as being of important societal health concern. It is critical that more funding is allocated towards improving the treatment of these diseases. Hopefully, our growing understanding of the role that epigenetic modification has in Alzheimer’s disease might offer a way to halt its debilitating consequences.
