Glioma in Insula Region of Brain
Feb 11, 2008 07:03AM in the Neurology Expert Forum
Thanks for the email Melodie and I'm sorry to hear about your husband. I assume they know the grade of the tumor based on a biopsy that has already been done? Grade 3 gliomas usually show enhancement on an MRI and grade 2 gliomas do not but it is the tissue which gives the correct answer. If the biopsy shows areas that are grade 3 then we call it a grade 3 tu...
ms vs alzheimer's
Nov 07, 2007 03:17PM in the Neurology Expert Forum
Thanks for the question and sorry to hear about your daughter and mother. It has long been thought that the two disorders are unrelated with MS affecting those generally less than 40 and AD affecting older patients. Below I have cut and pasted an interesting article about the two that shows a gene that may now link them: Alzheimer's and multiple sclerosis-...

This usual...

Viewed under a microscope, cavernous malformations appear to be composed of fairly large blood-filled "caverns." These blood vessel malformations may occur in the brain, spinal cord, co...
arm tremors

Thanks for the email. I have to tell you that I am trying to picture your problem and I am having trouble understanding what is going on from the description you give. Do you only have problems while "constricting" your arm? Essential tremor is tremor that is initiated by movement and goes away with rest. About 50% of ET cases are hereditary. I think that if ...
small fiber neuropathy
Sep 19, 2007 01:05PM in the Neurology Expert Forum
Thanks for the email. Most patients with small fiber neuropathies are diagnosed without a known cause and are called idiopathic. Common known causes include diabetes. If one does not know the underlying cause of the neuropathy then it will be very difficult to determine the relationship of the tremor. Most neuropathies are symmetric and usually affect the fee...
