Before I started treatment I had all of these symptoms especially the last one and I could not figure out for the life of me why. Then I found out dimensia is caused by untreated hypothyroidism. I still have all symptoms except for the last one now, but I don't throw things. I blow up on the littlest things and because I've already dug a hole for myself and am completely angry at myself and the world, am persistent on making everything worse and am completely out of control. Afraid to bring this up to my doctor. Afraid he'll just think I'm a nut who reads into things too much…..

People who have dementia often experience:

Confusion and memory loss.
Inability to complete everyday tasks.
Loss of self-control leading to unexpected behavior, such as throwing things, yelling at other people, or being suspicious of others.
Impaired judgment and reduced ability to make decisions and learn new things.
An eventual loss of control over physical functions, such as urination.

Sure, I'd say its possible, though dementia is a much broader scale disorder than hypothyroidism. maybe the better question would be is it possible to have hypothyroidism caused from untreated dementia. Dementia, being in a similar category as Alzheimer's, may result in the loss of affection for loved ones and even some romantic feelings. being also that hypothyroidism's beginning stages include a loss of seratonin and hormones, you'd be safe to assume that one disorder could lead to the other.
