Could spike protein be the hidden culprit behind brain fog, cognitive decline, and even Alzheimer's disease? Dr. Mobeen Syed (also called Dr. Mobeen or DrBeen) joins me to discuss the concerning persistence of the spike protein in the body and its potential to accelerate the progression of neurodegenerative conditions.

In this thought-provoking conversation, you'll learn about the latest studies revealing the impact of the spike protein on brain health and Alzheimer's disease. Dr. Mobeen discusses how it lingers in the body long after infection or vaccination, potentially causing long-term damage. We’ll explore the mechanisms by which the spike protein enters the brain, disrupts the blood-brain barrier, and leads to inflammation and cognitive decline.

If you’re concerned about Alzheimer's or want to understand how to protect your brain, don't miss this episode. Get informed, and join us in the fight against cognitive decline.

“Controlling inflammation does not fix the problem, but it fixes or reduces the damage done because of the problem.”
