There was recently a patient on rounds with suspected Hashimotos encephalopathy, but the team had questions about diagnostic criteria. I pulled a few articles and wanted to share them:
Hashimoto's Encephalopathy 2008 - nice review article which focuses on diagnosis (and specifically relevant auto-antibodies)
Hashimoto's Encephalopathy: Systematic Review of the Literature and an Additional Case 2011 - case report and systematic review which includes summary of symptoms associated with HE
High prevalence of serum autoantibodies against the amino terminal of alpha-enolase in Hashimoto's encephalopathy 2007 - discusses the use alpha-enolase autoantibodies in diagnosing HE. While there there have not been many studies, they appear to have good sensitivity and specificity.
