“Previous research has shown that epilepsy can affect bone health in some groups. Some anti-epileptic medicines can affect bone metabolism. This is a process that gradually replaces old bone tissue with new tissue – important in healing fractures, for instance. The medicines can prevent the body doing this as effectively as it should.”
“the article was published in The Journal of Paediatric Neurosciences. In it, authors state: “Low-dose vitamin D supplementation… is now recommended for healthy children and it is biologically feasible that children with epilepsy may be at higher risk of clinically significant deficiency. It is important that neurologists ensure that low-dose vitamin D supplementation should be prescribed… in children with epilepsy.”
A personal story in my book lends credence to this.
