A related discussion,
traumatic brain injury was started.
mlyn,
there is a hormone deficiency that can result from a traumatic head injury. Its called growth hormone deficiency. The somatrophs in the pituitary gland are extremely sensitive to damage and it is common to get this kind of problem with a head injury.
i know many patients being treated for this that have had head injuries.
this is a treatable disease.
symptoms include lack of concentration, brain fog, fatigue, and depression (and more).
i urge you to do some research on this so that you can see if he has this.
The neuro MD suggested thyriod tests and tests for B12 and peripheral neuropathies.
in addition-- a IGF-1 test should be done to see if he has low GH.
With growth hormone deficiency, the peripheral neuropathy can be related as well as the b12 deficiency. a thyriod problem could also tell you that the problem is in the pituitary gland-- where GHD stems from.
to start you off researching this subject go to:
hgfound.org
magicfoundation.org
growthhormonedeficiency.org
at the hgfound.org website there is an adult internet support group you can join and there are members that have had head injuries and are being treated for this deficiency.
good luck
There is a difference in B12 effects for some people. The form of B12 that is directly utilized by the body is methylcobalamin. The form normally given is cyanocobalamin. Some people can't convert enough to methyl and the symtoms such as your husband has MAY be the result. Its an easy thing to test for. Buy a small bottle of sublingual methylcobalmin at a healthfood store, about $8.00. Try it. If that is part of the problem there will be a noticable change within 15 minutes to 48 hours. It made a HUGE difference for me. I'm out from under a lifelong shadow. I knew in 15 minutes that my life was changed by that sublingual tablet.
As you are aware it is not uncommon for individuals who have had severe head trauma to have cognitive difficulties. However, if there has been a recent change, then I agree it should be evaluated. The treatable forms of dementia should be excluded by checking thyroid function, vitamin B12, and a test for syphylis (RPR). I think formal neruopsychological testing would be appropriate to define the areas which he is having difficulties in. Also, if brain imaging has not been performed, it should be considered.
The tingling in his toes and fingers could be related to a peripheral neuropathy, which is a dying back of the nerves. A EMG test may be useful to clarify this possibility. Common causes for peripheral neuropathy include: diabetes, thyroid disease, or B12 deficiency.
I hope these explanations help you. Good Luck
