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 Children’s National Health System
September 12-14, 2019, Washington, DC.


Senior, mid-level, and young investigators, clinicians and researchers 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. Multi-disciplinary specialists from around the world including adult and pediatric neurology/epilepsy, neurosurgery, psychiatry, neuroradiology, neuropsychology, genetics, endocrinology, epidemiology, cognitive sciences, and pharmacology will attend. Previous International Symposiums were held in Canada (2001), Marseille (2013), and London (2016).

Scholarships for Young Investigators Available


To encourage young investigators to pursue hypothalamic hamartomas as an area of practice and research, a limited number of scholarships are available to defray registration, travel, and hotel costs. Investigators are eligible if they are actively enrolled in a doctoral program, residence or accredited program of postgraduate education in neurosciences/epilepsy or are new faculty (at or below the rank of Assistant Professor). Priority will be given to women, racial/ethnic minorities, and persons with disabilities. To be considered, submit the information below in a single email to ilenepennmiller@gmail.com. Please write “HH Symposium Scholarship” in the subject line. The deadline is June 30, 2019. Awards will be confirmed by July 15, 2019.
