4th International Symposium on Hypothalamic Hamartomas


The 2019 Symposium aims to identify gaps in understanding and opportunities for future Hypothalamic Hamartoma research studies and collaborations.

Presented by Hope for HH and Childrens National Medical Center
September 12-14, 2019, Washington, DC.


Senior, mid-level and young investigators will gather for a two-day research symposium on hypothalamic hamartomas (HH), a rare disorder associated with refractory epilepsy, epileptic encephalopathy, intellectual disability, behavioral comorbidity, and endocrinological dysfunction. We will analyze HH as well as other disorders/diseases entities that involve hypothalamic dysfunction and other genetic epileptic encephalopathies also with psychiatric co-morbidities to find commonalities and distinctions that may inform investigations to the combined disorders. Current HH treatment and managements will be reviewed. Results of ongoing HH research into animal models, comparative effective treatment pilot, FMRI, genetic, and cannabidiol research will be shared and discussed. Previous International Symposiums were held in Canada (2001), Marseille (2013), and London (2016).
