Hello, I'm a twenty year old girl from East Texas living in D. C. for college. I have a question about possible B12 deficiency neurological symptoms. I've got the last six months or so of my physical state written below, if you would rather not read that and just skip to the question, I don't mind :-) Thanks for any help!
Since November, I haven't been feeling well. My initial symptoms were fatigue, difficulty concentrating, and loss of appetite. I just chalked it up to college life and continued on with myself. My symptoms worsened and increased at the end of January. The above were enhanced and I also began having nausea, some confusion (fuzzy head, some slight short-term memory loss) and weakness. Now all these symptoms were irritating, but not necessarily debilitating. I was still going to class, writing papers, and enjoying myself on Friday nights. Around March things took a definite turn. Everything was much worse, the fatigue and weakness had become absolutely draining and the "fuzziness" in my head had become a thick fog. I started to occasionally experience either disorientation and loss of balance. I still lived my day to day life as usual, but I was becoming worn down.
I went to the local health center on campus (end of March) and was tested for anemia, thyroid levels and some other things. Everything came back fine, except I had a slightly elevated White Blood Cell count. The doctor said she wanted to test again a week later and see if the level went down. I scheduled the appointment for the next Monday. That week my disorientation/ loss of balance increased dramatically and on Friday (the Friday before my appointment) night, I began experiencing full body tremors. The ER doctor said it was likely anxiety. He said that they would stop, gave me Lorazepam, and sent me home. The tremor's persisted until Saturday night (nearly 24 hours after they started) and calmed down into gentle jerks in my legs. As the tremors calmed, I began to get a very bad headache, starting from neck and creeping to my forehead. The mental fog had increased to the point where I did not even feel like I was there, similar to a constant out-of-body experience. That Monday the doctor referred me to a neurologist and I was able to get in that afternoon at a local clinic. The neurologist ordered blood work, and EEG, and an MRI. I had the blood work done that day, and scheduled the other two tests for that week.
Two weeks have passed and I have received the results. My EEG and MRI are fine and the blood work largely came back normal. The only cause for concern is my B12 level. The range on the paper is 200-1100. My score is 287. On the paper is a note stating that though the range is 200-1100, 5-10% of people with scores in the range of 200-400 experience neuropsychiatric and hematological symptoms due to occult B12 deficiency. I've researched the deficiency and the symptoms listed match mine to a T.
I am curious if a person can have neurological symptoms due to B12 deficiency without actual damage appearing on an EEG or MRI.
