Question for written answer E-002004-19
to the Commission
Rule 130
Nicola Caputo (S&D)

 Subject:  Herpes simplex as a potential Alzheimer's risk factor
 Answer in writing 

According to a paper published in PLoS Pathogens, laboratory tests have shown that the Herpes simplex (Hsv-1) virus could be a trigger factor for Alzheimer’s disease.

This study is an important addition to the many years of research conducted into the role of microbial agents in the onset of neurodegenerative diseases.

Repeated reactivations of the Hsv-1 virus cause the appearance and accumulation in the brain of typical Alzheimer’s disease neurodegeneration biomarkers such as amyloid beta peptides (the main component of senile plaques), the Tau Hyperphosphorylation protein (which forms neurofibrillary tangles) and neuro-inflammations.

Can the Commission state, within the limits of its competences:
1. What research findings it has on this matter;
2. Whether it will act on research into new treatment and/or preventive strategies designed to limit viral reactivations and the spread of this virus to the brain?
