Researchers have discovered that treatment with vitamin C can
dissolve the toxic protein aggregates that build up in the brain in
Alzheimer’s disease.
The brains of people with Alzheimer’s disease contain lumps of
so-called amyloid plaques which consist of misfolded protein aggregates.
They cause nerve cell death in the brain and the first nerves to be
attacked are the ones in the brain’s memory centre.
“When we treated brain tissue from mice suffering from Alzheimer’s
disease with vitamin C, we could see that the toxic protein aggregates
were dissolved. Our results show a previously unknown model for how
vitamin C affects the amyloid plaques”, says study author Katrin Mani.
“Another interesting finding is that the useful vitamin C does not
need to come from fresh fruit. In our experiments, we show that the
vitamin C can also be absorbed in larger quantities in the form of
dehydroascorbic acid from juice that has been kept overnight in a
refrigerator, for example”.
There is at present no treatment that cures Alzheimer’s disease, but
the research is aimed at treatments and methods to delay and alleviate
the progression of the disease by addressing the symptoms.
That antioxidants such as vitamin C have a protective effect against a
number of diseases, from the common cold to heart attacks and dementia,
has long been a current focus of research.
“The notion that vitamin C can have a positive effect on Alzheimer’s
disease is controversial, but our results open up new opportunities for
research into Alzheimer’s and the possibilities offered by vitamin C”,
says Katrin Mani.
