I thought you might be interested in a study I found some time ago where they actually were able to quantify the reduction effects of mild hypothyroidism on cerebral blood flow. they also found that correction of the hypo condition did not immediately return the CBF to normal. As I remember it, the time required varied among patients but there was a lag for most. This correlates with what we have noticed many times about there being a lag between getting blood levels of thyroid hormone optimized and the time at which symptom relief occurs.
foreverlostmom: Understand that I am not minimizing any effect of being hypo. I don't know if it is relevant for you or not, but you reminded me of the time when I took a really good class in rapid reading. It was not one of those that claimed to be able to get you up to some unbelievable level. If you are interested, I know that similar approaches are available for a small fee on the internet. I learned that one of the biggest problems was that the brain is capable of doing so much more than asked to do that your attention wanders all over and you don't really absorb what you read. I always thought I was pretty good at reading, but in 8 weeks (8 classes), plus some homework, I went from about 120 words per minute with 40 % comprehension up to almost 1000 wpm at 85 comprehension, and it wasn't that difficult. Imagine what that could do for your studying.
I've had this issue of not rememembering as well, I graduated with my BS May 2009. i found that making power point slides and studying them just before an exam helped tremendously...even getting the highest mark on a Final in one class...BTW...I'm 45 yrs old.
I don't know but I am sure having a hard time in my classes my brain just doesn't remember what I read.
Is the same true for Hyper?
Neurologically, hypothyroidism is very tough to manage. The symptoms can range from "brain fog" ( term used often for symptom) - to Bi Polar disorders to complete retardatiopn - sometimes permanently if not regulated correctly.
The mental clinical labels are common with people suffering hypothyroidism and many can also be labeled ADD or ADHD and given those medications - mistakenly when a hormone adjustment should be done.
