Researchers have found that increasing dopamine production in mice with Alzheimer’s disease improves their memory, a process they’re hopeful can be replicated in humans, though more testing for a better human alternative must be done.A research team from Japan’s RIKEN Center for Brain Science tested the new treatment method, boosting the production of dopamine in the brains of mice with Alzheimer’s in the hopes of increasing levels of an enzyme called neprilysin.
The scientists were able to continuously activate the neurons in the mice’s brains that produce dopamine, and after eight weeks the mice had significantly fewer plaques in their brains, according to a new study published Tuesday in Science Signaling.
The medication was given for three months and led to an increase in neprilysin and a subsequent decrease in beta-amyloid, and the mice that were given this treatment performed better on memory tests than the placebo group that wasn’t treated with the drug.
