Dear Dr. Roach: In a recent column, you wrote that migraine of any kind starting in a person’s 60s is uncommon. I am a 66-year-old man in relatively good health. I have controlled blood pressure and cholesterol. In the past six months I have started following a “plant-centric” diet and my blood pressure and cholesterol are well within guidelines. My heart rate is in the 43-47 beats per minute range and I have lost more than 29 pounds since October 2019. I weigh 217 and am six feet, three inches tall.
I recently went for my annual vision check at my eye doctor and told him about seeing a shimmery, jagged, half-moon blur in my vision, mostly on in my left eye, but present in both eyes occasionally.
He did a thorough retina exam and found no abnormality. He speculated that I was experiencing a migraine. I asked why there
