About HESA

The Hashimoto’s Encephalopathy SREAT Alliance is a 501(c)(3) nonprofit organization formed in 2012. It is HESA’s mission to collect, archive, and share information regarding Hashimoto’s encephalopathy (“HE”), also known as steroid responsive encephalopathy associated with thyroiditis (“SREAT”) or simply autoimmune encephalopathy (“AE”) with the public and medical professionals.

“The Hashimoto’s Encephalopathy SREAT Alliance is a 501(c)(3) nonprofit organization formed in 2012.”

Other names used to describe  HE/SREAT are nonvasculitic autoimmune meningoencephalitis (“NAIM”), and encephalopathy associated with autoimmune thyroid disease
(“EAATD”).  HESA takes no position on the most appropriate name for the disease, however on this website the abbreviation “HE” is generally used as
a shorthand way to refer to the condition.

The purposes of HESA are exclusively charitable, educational, and scientific. Our primary focus is to educate the public and physicians concerning Hashimoto’s encephalopathy and associated diseases and disorders. We aim to educate the public concerning the need for increased funding for the detection, treatment, and ultimate cure of Hashimoto’s encephalopathy and associated diseases and disorders. We hope to one day assist in finding a cure of Hashimoto’s encephalopathy.

We foster, promote, support, develop, encourage, solicit, maintain, receive and accept funds, and raise funds for and on behalf of such purposes. We fully appreciate your tax-deductible donations which enable us to continue to educate and raise crucial awareness of this poorly understood condition.

All the volunteers at HESA thank you for your continued support of our efforts and our work in educating the public about this condition.
