SREAT or Hashimoto’s Encephalopathy?
The terms Steroid Responsive Encephalopathy Asssociated with Thyroiditis (SREAT) and Hashimoto’s Encephalopathy (HE) refer to the same condition. There is no difference between the two. Additional terms are used by some researchers, including Encephalopathy Associated with Autoimmune Thyroid Disease (EAATD), and Non-vasculitic Autoimmune Inflammatory Meningoencephalitis (NAIM). All of these terms refer to the same syndrome.
The scientific community has not yet reached a consensus on which term is best. Criticisms of the term “Hashimoto’s Encephalopathy” point to the fact that HE is not caused by Hashimoto’s Thyroiditis, but is instead merely a co-existing condition. Critics of the term “Steroid Responsive Encephalopathy Associated with Thyroiditis” point out that this name suggests that steroid-responsiveness is a defining characteristic, yet some HE/SREAT patients – albeit a minority – do *not* respond to steroids.
Until the scientific community reaches a consensus, we must accept that all of these terms are “valid” names for what we, at this site, generally refer to as Hashimoto’s Encephalopathy.
