Guided by precise
biomarker tests, therapeutic vaccines targeting the pathology of
neurodegenerative disease could provide solutions to the impending global
crisis in dementia. As Dr Andrea Pfeifer, Co-Founder, Chief Executive Officer
and Director of AC Immune, describes here, current work is both establishing
the targets that those vaccines must address and refining the techniques for
addressing them.
The
prevalence of dementia due to neurodegenerative conditions such as Alzheimer’s
disease (AD) and Parkinson’s disease (PD) is expected to rise as life
expectancy increases across the global population.1 Around 50
million people worldwide are already affected by dementia, a figure that is
expected to nearly triple by 2050.2 Approximately 20 percent of
women and 10 percent of men will develop AD,3 while PD affects
over six million people making it the second most common neurodegenerative condition. Progressive memory loss,
language processing impairment and dementia lead to a loss of independence and
incur high costs in family-based or institutional care.
