Which symptom is commonly associated with Huntington's disease in children?

In children with Huntington's disease, gait impairment is a notable symptom due to the progressive neurological decline that the condition entails. Huntington's disease is primarily characterized by chorea, which refers to involuntary, irregular movements. As the disease progresses, this can significantly affect motor control, leading to difficulties in coordination and balance. Consequently, children may exhibit a waddling gait or have trouble walking, resulting in pronounced gait impairment.

While the other symptoms like epileptic seizures, autistic behaviors, and vision loss may occur in other conditions affecting the nervous system or in broader developmental disorders, they are not typically associated directly with Huntington's disease in the pediatric population. The hallmark features of Huntington's—movement disorders, cognitive decline, and mood alterations—are more directly represented by the presence of gait impairment as children manifest the motor symptoms of this degenerative disease.
