Simple blood Calcium levels can indicate Parathyroid problems. When the Parathyroid is whacked, Calcium can rapidly deposit in the brain. Try this scenario: A mycoplasma infection compromises the Thyroid and Parathyroid. Calcium is laid down in the brain to sooth the irritation. As has been seen in Australia, "Alzheimer's" responds to Antibiotic use, cleaning up the Thyroid/Parathryoid function, and reversing Calcium deposition in the brain.
