Wilsons disease
My five-year-old has been tested for Wilsons disease. He has tremors in his hands and is very clumsy. He gets irritable and agitated, and every five weeks, he has a few days of vomiting. I've been searching the Internet for answers but lots of symptoms seem to describe my sons condition.
It is a rare, but important inherited disease, in which the content of copper in the body is increased, with excess copper being deposited in, and possibly causing damage, to several organs. The liver is the first place where the excess copper accumulates and is often the first organ to show abnormal features. Any excess copper from the full liver will then appear in other organs.
I can reassure you and say that the prognosis for Wilsons disease is excellent provided that treatment is started early. Essentially your sons symptoms could indicate Wilsons disease if there are certain changes in his blood levels. These include: low serum caeruloplasmin (the special enzyme which uses copper), low serum copper, increased urinary copper, or elevated copper in the liver.
Your little one is just five years old, the encouraging thing is that if Wilsons disease is eventually diagnosed, treatment will certainly be early, and therefore much more effective.
