Dolphin Brain Damage Linked to Algal Toxins, Similar to Alzheimer's

Algal Toxins and Dolphin Brains

• 🐬 Dolphins exposed to toxic algae can exhibit unusual and disorientated behavior, with some showing signs of Alzheimer's disease-like symptoms.
• 💡 Research from the University of Miami's Miller School of Medicine revealed striking similarities between the brains of dolphins exposed to algal toxins and those of humans with Alzheimer's.
• 🔬 A study examined 20 bottlenose dolphins from the Indian River Lagoon between 2010 and 2019, finding Alzheimer's disease changes and specific algal toxins in their brains.

Neurodegenerative Similarities

• 🧠 The toxin 24DAB was found in dolphins, leading to a disregulation of their inhibitory synapse, a change also observed in Alzheimer's disease.
• ⚠️ Comparable changes were noted in the dolphins' blood-brain barriers.

Potential Human Impact

• 🩺 A co-author on the paper, Paul Allen Cox, found that exposure to toxic algae, specifically a toxin called BMA, can impact human brains.
• ⚡ This exposure can lead to neurodegenerative-like symptoms in humans, suggesting a broader implication for environmental toxins.
