So let's talk about the "it's nobody's business" nonsense.
Please take a few minutes to read this latest report from Biden's doctor:
Generally speaking, medical information, including mental health, is private information. There are laws to protect your medical privacy. However, as the report above illustrates, the rules are quite different with public figures, and especially the President of the United States.
If you take the time to read that report, you'll learn that Biden had a skin lesion removed from his chest that was basal cell carcinoma. You'll learn that he has obstructive sleep apnea and now requires a CPAP machine while sleeping. You'll learn that he had a dental urgency and root canal last June. You'll learn that he has non-valvular atrial fibrillation that is stable. You'll learn that Biden takes Eliquis for standard anticoagulation. You'll learn that he has hyperlipidemia, which he takes Crestor for, which is stable. You will learn his total cholesterol level. You will learn that he has gastroesophageal reflux, for which he takes Pepcid and Nexium. You'll learn that he has seasonal allergies for which he takes Dymista and Allegra. You'll learn that after an X-ray they determined that Biden's stiff gait is a result of degenerative osteoarthritic changes of his spine. You'll learn that he has no cerebellar or other central neurological disorder. You'll learn that he has excellent fine motor dexterity. You'll learn that there was finding of peripheral neuropathy in both of his feet. You'll learn that he undergoes regular physical therapy and what that entails. You'll learn that Biden is not diabetic. You'll learn that his thyroid is functioning normally. You'll learn that he had an ey exam. You'll learn that he went to the dentist and had to have a root canal. You'll learn that he's been happily married for 46 years and does not use tobacco or alcohol and that he works out five days per week. You'll learn that he's 72 inches tall, weighs 178 LB and has a BMI of 24.1. You'll learn that his blood pressure was 132/78, his pulse was 64, his respiratory rate was 14, his body temperature was 98.6 and his blood oxygen level was 98%. You'll learn that his CMP, Urinalysis CBC, vitamin D level, homocysteine level, folate, creatine kinase and magnesium levels were all normal.
ALL of that information is private, protected health information. Yet it's been made public.
Conspicuously absent from that 6-page report is ANY mention of cognitive abilities. It's remarkable for me to think that someone would try to contend that we can know EVERYTHING about Biden, right down to his vital signs, but somehow his cognitive abilities are private and none of our business.
