At timestamp 54:40, Dr. Shawn Javid tells the story of a patient that was a man from Florida.  He made his career as a writer, but he had to stop due to brain fog.  He had severe brain fog to the degree that his mainstream medical doctor diagnosed him with early onset Alzheimer’s Dementia.  Dr. Shawn Javid found that he had dental cavitations.  Dr. Shawn Javid did dental cavitations surgery on him.  Within 4-5 weeks, the patients brain fog had reduced so much that he started writing again.
