Possible link between harmful algal blooms and β-N-methylamino-L-alanine (BMAA) neurotoxin

Algal blooms are on the rise worldwide, but no one has yet conducted comprehensive research to prove that they are a global phenomenon. β-N-methylamino-L-alanine (BMAA) is a neurotoxin with neurodegenerative effects, and recent studies suggest that it may play a role in the development of Alzheimer's disease and amyotrophic lateral sclerosis/Parkinson's disease (ALS/PDC). In 2003 it was described that cyanobacteria in water can also produce BMAA.
