HESA is a 501 3(c) not for profit organization for an autoimmune brain disease
called Hashimoto's Encephalopathy (HE). 
HE is a sero negative form of autoimmune encephalitis (AE).
Sero negative means there is no known antibody to cause it.

We provide support for patients/caregivers diagnosed with HE, Sero Negative AE and those searching
for a diagnosis on our support groups.
We provide the latest available information, research and resources on Hashimoto's encephalopathy
and other types of autoimmune encephalitis.
We raise awareness by participating in educational medical symposiums, 
donating money towards research and writing books.
Here you will find many resources to help live with HE and Sero Negative autoimmune brain disease .
