Hello all,
I had a pituitary illness before MS.
I am deficient in all pituitary hormones (testosterone, thyroid hormone, growth hormone, cortisone and anti-diuretic hormone).
My MS was long mislabelled a psychiatric problem after to a medically-induced psychosis.
(Many people lose the plot on a high dose of steroids, everyone does if their salt levels and electrolytes are out far enough).
My MS symptoms were only cognitive and some sensory ones.
The book I just read is That Memory Book How to Deal with Distractibility, Forgetfulness and Other Unnerving High Jinks of the Middle-Aged Brain Virago 2008 reprint copyright 2007 Cathryn Jakoson Ramin

The following section suited me to a T and is rather OMS too :
p. 206 scientists speculate brain uses thyroid stimulating hormone in hippocampus to store and encode memory, when there is not enough tsh or body doesn’t metabolise it, cognitive problems begin
thyroid hormones affect the rate of cell growth in the brain, as well as the rate at which synaptic impulses travel
many doctors think there’s no need to fiddle around with tsh levels- lowering the tsh range would increase percentage of population hypothyroidism diagnosis from 5% to 20 %, of no benefit but to Abbott Laboratories the company that manufactures Synthroid.
p. 207 she found a thyroid expert
He and a growing number of thyroid specialists believe that you can’t go by the tests – that the only way to accurately assess a patient is to listen and look
First endocrinologist who had missed it had ignored her own diagnosis
‘She nailed it. Thinning hair, cold hands and feet, low blood pressure, memory and concentration problems, sleep difficulties,’ he said, shaking his head. ‘And then she ignored her own diagnosis, because of the test results.’ That news set me back on my heels. [he] began to examine me in earnest …
p 208 in addition to tsh thyroid stimulating hormone he ordered the trh thyrotropin-releasing hormone
p210-211 ‘You know,’ I said, ‘ a lot of doctors think that treating subclinical thyroid disorders is inappropriate. I’ve also been told that too much thyroid can have a profound effect on bone metabolism – that it can cause osteoporosis.’
‘I’m aware of these things,’ he said gently. ‘I hope that one day, the controversy will be resolved and doctors will actually treat patients, rather than numbers.’ …
For a long time, I was angry at that endocrinologist, for what seemed to me to be blatant disregard of what was written all over the patient who stood before her. If she’d treated me for subclinical hypothyroidism when I was forty-two, there was so much I could have avoided. She was too busy to take the time to look and listen, too anxious to make her way to the patient in the exam room next door. Eventually, I realized that it wasn’t entirely her fault. I’d given up too easily. I hadn’t had enough confidence, or enough research behind me, to tell her I thought she was wrong. There was a lesson for all of us, I thought: Understand that doctors are human. They are not infallible. They are often uninformed or ill-informed. They have agendas. So, do the research. Show up with the documents in hand. Make yourself crystal clear — skip that Doctor is God routine which is ingrained in all of us. And if that doesn’t work, find another doctor.
