Exposure to a toxin, Beta-N-methylamino-L-alanine (BMAA), from algae may be linked to dementia. This finding could offer fresh clues for the possible causes of the condition and potential future treatments. Research suggests that provision of L-serine in the diet might reduce the build-up of harmful proteins in the brain and reduce dementia / neurodegenerative risks.
