Some tiny ocean algae make a poison that tricks your brain cells into over-firing, which can scramble your memory and even cause seizures or death.
Evidence Quality Assessment
Claim Status

Study Design Support
Design cannot support claim
Appropriate Language Strength
association

Assessment Explanation
The review reports mechanisms and outcomes from prior studies but does not provide new experimental evidence; causal language is inappropriate for a narrative review.
More Accurate Statement
“Domoic acid produced by Pseudo-nitzschia diatoms is associated with amnesic shellfish poisoning in humans, characterized by glutamate receptor overstimulation leading to excitotoxic neuronal damage, memory loss, and seizures, based on clinical and experimental evidence from prior studies.”
Gold Standard Evidence Needed
According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Microalgae toxins in food products and impact on human health: a review
This study says that tiny ocean algae can make poisons that get into shellfish and make people very sick — even causing memory loss and seizures — which matches what the claim says about domoic acid.
