hi there and welcome to the forum. you are certainly not crazy and from your description the doc knows it.
in case you are not already aware of this - OCD FYI:
Nutritional therapies for mental disorders
"Notably, essential vitamins, minerals, and omega-3 fatty acids are often deficient in the general population in America and other developed countries; and are exceptionally deficient in patients suffering from mental disorders. Studies have shown that daily supplements of vital nutrients often effectively reduce patients' symptoms. Supplements that contain amino acids also reduce symptoms, because they are converted to neurotransmitters that alleviate depression and other mental disorders".
the rest of the article is not as good, eg their 'Summary of proposed causes and treatments for common mental health disorders' (table 1) is only so-so and regarding OCD, it's actually pretty stupid.
so, from another source, a bit more info:
Vitamin B12 and folic acid serum levels in obsessive compulsive disorder
"Six patients (20%) of the OCD group had abnormal low levels of vitamin B12
. This prevalence was significantly higher than that of the control groups. No clinical neurological or haematological abnormalities accompanied the reduced vitamin B12 levels."
i had to look at how they arrived at the 20% figure. turns out their cutoff for low vs 'normal' was 200 pg/ml
the mean result for all 30 OCD patients was 328. the standard deviation was 162 so their range was 166-490. 6 patients had levels lower than 200, and 24 had levels higher than 200. 6 is 20% of 30 so that's how they arrived at that number.
i thought using 200 was a bit fishy, since i know that the cutoff for deficiency in SI units, is 180 pmol/L. (which only uses haematological criteria and does not involve cognitive deficits).
i couldn't remember the units conversion so i looked it up sort of expecting perhaps the pmol number would be a little higher than 200, or at worst it could take it down to 180.
units conversion factor: 0.738
200 pg/ml * 0738 = 147.6 pmol/L.
unbelievable. there is literature out there suggesting that 500 pmol/L should be the cutoff to prevent cognitive deficits
resulting from sub-optimal b12 status. so by that standard, with a range of 166-490 for all OCD patients in the study, 100% had low b12
. not 20% as stated.
i wonder what the heck assays they were using in order to conclude:
"No clinical neurological or haematological abnormalities accompanied the reduced vitamin B12 levels"
all this is by way of saying, your vitamin b12 and folic acid may be low. vitamin b12 deficiency is a major differential diagnosis for ms
i was diagnosed at 35. i definitely had a documented background of b12 deficiency which went under the radar as the neuros were diagnosing me.
i had weakness of the hands and numbness of the feet prior to my first outright 'ms' attack. in early days it was reversible if i would take b12 supplements. as the years wore on with me largely ignoring things, i did enough damage that i can't reverse it 100% any more.
sorry i don't usually unload to that degree on a newbie, and if you were already aware of the b12 link, my bad - maybe it will help a future reader
