Hi there and thanks so much for your question! I would recommend you to post in the Neurology Forum as well.
I will give you my own opinion and several sources of reference in case you want to explore more about this fascinating topic.
A study conducted at Albert Einstein College of Medicine, Bronx, New York, and published in the November 2004 issue of "The Journal of Neuroscience" concluded that calcium EDTA is a potentially effective rescuer for stroke-induced brain ischemia, the restriction of the blood supply in some parts of the brain resulting in brain tissue damage and dysfunction. In this study, the researchers demonstrated the ability of calcium EDTA to preserve the integrity of the function of the brain mitochondria, the producer of energy within the brain cells. But further clinical trials are necessary.
Calcium deposits on the brain or cranium calcification are not uncommon at all. They are caused when calcium in the bloodstream is not absorbed by the body and is deposited on the brain. There can be many different causes of calcium deposits on the brain. However, they usually go unnoticed and cause no serious problems

However calcium in the brain can pose larger benefits In this regard studies are suggesting that "Scientists link increase of calcium influx in brain neurons to long-term memory" http://www.news-medical.net/news/20110415/Scientists-link-increase-of-calcium-influx-in-brain-neurons-to-long-term-memory.aspx
So how does exercise affect our levels of calcium? There is strong research showing that calcium needs to be transported by blood into the brain and what a better way of doing it through exercise.

Exercise stimulates calcium metabolic hormone and increases blood calcium levels, thereby increasing DA synthesis in the brain. Subsequently, increased DA levels regulate various brain functions. Therefore, exercise-induced stimulation of calcium-dependent DA synthesis might be a mechanism by which exercise modifies brain function.

So in my opinion you need to engage into regular physical activity exercises that will involve blood transportation meaning that if you train several muscle groups at once you heart will transport more blood that training a single muscle group. My program is based on those movements since I believe there are more efficient and better for a greater brain muscle function.
