In the first decade of life speech difficulties, rigidity, and dystonia are common clinical motor symptoms, whereas onset in the second decade motor symptoms may sometimes resemble adult-onset Huntington's disease (AOHD). Cognitive decline is mostly detected by declining school performances. Behavioral symptoms in general do not differ from AOHD but may be confused with autism spectrum disorder or attention deficit hyperactivity disorder and lead to misdiagnosis and/or diagnostic delay. JHD specific features are epilepsy, ataxia, spasticity, pain, itching, and possibly liver steatosis. Disease progression of JHD is faster compared to AOHD and the disease duration is shorter, particularly in case of higher CAG repeat lengths. The diagnosis is based on clinical judgement in combination with a positive family history and/or DNA analysis after careful consideration. Repeat length in JHD is usually > 55 and caused by anticipation, usually via paternal transmission. There are no pharmacological and multidisciplinary guidelines for JHD treatment. Future perspectives for earlier diagnosis are better diagnostic markers such as qualitative MRI and neurofilament light in serum. date: 2024-04-26 date_type: published publisher: IOS Press official_url: http://dx.doi.org/10.3233/jhd-231523 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 2271552 doi: 10.3233/JHD-231523 medium: Print-Electronic pii: JHD231523 lyricists_name: Byrne, Lauren Mary lyricists_id: LMBYR59 actors_name: Flynn, Bernadette actors_id: BFFLY94 actors_role: owner full_text_status: public publication: Journal of Huntington's Disease event_location: Netherlands issn: 1879-6397 citation: Oosterloo, Mayke; Touze, Alexiane; Byrne, Lauren M; Achenbach, Jannis; Aksoy, Hande; Coleman, Annabelle; Lammert, Dawn; ...
