Limited data exists regarding the disease course of Huntington's Disease (HD) in children and young adults. Here, we evaluate the trajectory of various cognitive skill development as a function of cytosine‐adenine‐guanine (CAG) repeat length in children and adolescents that carry the mutation that causes HD. We discovered that the development of verbal skills seems to plateau earlier as CAG repeat length increases. These findings increase our understanding of the relationship between neurodegeneration and neurodevelopment and may have far‐reaching implications for future gene‐therapy treatment strategies.
