"Sylvie" is a high-powered lawyer, originally from West Africa, living in the northwest of England. She came to see me in her early 50s, very distressed that she was losing focus, starting to forget words and occasionally struggling with spelling (she was not dyslexic).
These symptoms were not constant, but they occurred often enough to worry her. The cleverer people are, the sooner they notice the subtle signs of their own cognitive decline. A CT scan gave her a diagnosis of early Alzheimer's disease.
As always, I began by wondering about causes. The first cause we found was a simple but devastatingly common (and easily preventable/treatable) one: vitamin D deficiency. When I say deficiency, I mean, in her case, almost a total lack of this important nutrient.
