Hashimoto's Encephalopathy/SREAT & Seronegative Autoimmune Encephalitis Alliance
Providing patient support to, public awareness of, and medical research for Hashimoto's Encephalopathy (HE)/SREAT and Seronegative Autoimmune Encephalitis (SAE).
HESA is a 501 3(c) not for profit organization for
Autoimmune Encephalitis, specifically Hashimoto's Encephalopathy/SREAT (HE/SREAT) and
Seronegative Autoimmune Encephalitis (SAE).
Seronegative means there is no known antibody identified as the cause of Autoimmune Encephalitis.
The Hashimoto’s Encephalopathy/SREAT & Seronegative Autoimmune Encephalitis Alliance was formed in 2012 by two HE patients.
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”),
and Seronegative Autoimmune Encephalitis ("SAE") with the public and medical professionals.
We share information relevant to HE/SREAT and SAE as well as updates on HESA's activities and our publications.
In the 10 years HESA has been in existence, we have published two books, hosted symposiums, held many webinars and supported so many.
One thing we haven't done is fundraising. But now is the time! We want to begin funding our long term goals of research, more education and even more support.
