I read a very similar article not that long ago, and forwarded it to my dad who is a surgeon. He said that tapeworms are very common in developing nations, specially Asia and South America. In "99.9%" of the cases the eggs are digested or the cyst shows up in an organ causing relatively low damage with "easy" extraction possible. Unfortunately, some of those eggs/worms can find their way into the head.
His advice was to cook all meats (be it pork, steak, etc.) well, and to avoid eating raw/uncooked meat. Apparently it reduces the chances of eating a living egg. No more medium-rare burgers for me since then.
