An Older Adult Woman Who Stops Using Complementary Alternative Medicine

An older adult woman who stops using complementary alternative medicine (CAM) becomes disoriented and is given a diagnosis of dementia. The family is upset with the family physician and the CAM practitioner for not diagnosing the condition earlier. Which CAM may have interfered with early detection of the dementia?

A) Large doses of calcium caused cerebral plaques to form, thereby disguising atrophy of the brain.
B) Excess doses of folic acid masked a vitamin B₁₂ deficiency that led to dementia.
C) Hypnotherapy focused on current pleasant thoughts, eliminating clues to the past.
D) The electrical current from magnetic fields interfered with normal brain waves, resulting in confusion and inability to concentrate.
