brain scans 1A recently published case study showed that neurological symptoms can occur in Hashimoto’s patients. SPECT brain scan imaging showed reduced brain activity (hypoperfusion) both in patches and throughout the entire brain. The brain scan images completely changed after subjects were given corticosteroids to suppress the autoimmunity, showing improvements in many areas. However, patchy areas of impairment persisted despite autoimmune suppression.
brain scans 1This study illustrated two key concepts. First, Hashimoto’s impairs brain function and dampening autoimmunity can improve function. Second, areas of continued brain degeneration persist despite treatment that dampens autoimmunity.

I cannot stress enough how important it is to improve your brain health when you have Hashimoto’s. This is exactly why I wrote Why Isn’t My Brain Working?—it is so critical for my Hashimoto’s readers. In in my practice I have found the most important second step Hashimoto’s patients must take after reducing their autoimmune expression is to optimize their brain function.

    No it’s just a risk to be aware of, another reason to manage the autoimmunity and not just treat solely with hormones.

    this is very interesting. I wonder if Hashimotos can effect the brain so much as to cause seizures?

      I have been asking this very question because this happened to me. When I was diagnosed with Hashimotos and put on meds within two weeks I started having seizures. Not to mention, every time my meds have been changed I have another seizure!

    Optimize our brain function. Kindly elaborate further? thanks

    I have Hashimoto’s and a recent ultrasound showed that my thyroid is now GONE! I tested for Gluten intolerance and Blood-Brain Barrier issues (through Cyrex Labs), and although I don’t have any Gluten issues, I do have increased Blood-Brain Barrier antibodies, which makes me wonder what kind of toxins are passing the BB-Barrier and potentially damaging my brain?
