EHDN 2022 | Symptoms of juvenile onset Huntington’s disease

Huntington’s disease (HD) is often wrongly considered as a disease that exclusively affects adults. In rare cases, HD onset can occur in children and young people aged under 20, known as juvenile onset HD (JHD). Presenting symptoms of JHD differ significantly from those classically seen in adult-onset disease. For example, neurodevelopmental delays or behavioral challenges are often seen early on and can lead to misdiagnosis. Ferdinando Squitieri, MD, PhD, IRCCS Casa Sollievo della Sofferenza, San Giovanni Rotondo, Italy, shares an overview of the signs and symptoms that can indicate the presence of JHD. JHD is underrecognized and its variable manifestations and dissimilarities from adult disease mean neurologists and even families carrying the HD gene can sometimes fail to recognize it. This interview took place during the European Huntington’s Disease Network 2022 Plenary Meeting.
