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...
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-...
Thanks for the email. Numbness only in the thigh can be from multiple causes but usually is related to some irritation of nerves from the lumbar spine area. There is a condition call meralgia paresthetica in which the lateral femoral cutaneous nerve (sensory nerve that has already left the spine) gets irritated as it crosses the inguinal ligament. This usual...
Sorry to hear about your problem: Cavernous malformations are groups of abnormal, tiny blood vessels and larger, stretched-out, thin-walled blood vessels filled with blood. 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, spina...
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 thin...
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...
Thanks for the email Herb. New onset of "headache" in someone who is 57 always raises some concern. It is possible that it is nothing serious and it does not sound like the symptoms have progresed which is good. The suggestion of trigenimal neuralgia has been raised. The trigeminal or 5th cranial nerve has 3 division. Patients can have pain related ...
Thanks for your email and sorry to hear about your problem. I think your doctor did the correct thing initially sending you to the the ED given your story. I'm glad the US was negative. Most of the time the US looks at the venous system and not the arterial system. Arterial clots are very rare and mostly related to trauma or some type of clotting disorder. If...
Thanks for the email and sorry to hear about your daughter and her problem. Make sure that the MRI also includes the thoracic spine since that seems to be the area of skin change. The history would be concerning for a lesion affecting the thoracic cord. Lesions in the cord often cause transverese myelitis or inflammation of the cord. Cord lesions often cause ...
Thanks for the question. I'm afraid you did not give me too detailed a history to go on. I think the simple answer is you have to follow up on the last MRI you had especially since you are using a wheelchair at home. If you do have MS there are several drugs on the market currently that can help slow the progression of the disease. It is not usual to have swe...
