Which condition is characterized by difficulties controlling movement due to muscle issues?

Cerebral palsy is characterized by difficulties controlling movement, primarily due to issues affecting muscle tone and coordination that originate from abnormal brain development or injury to the developing brain. Individuals with cerebral palsy may experience stiffness or weakness in their muscles, which can lead to challenges in achieving and maintaining balance, posture, and overall movement.

Unlike the other conditions listed, which may involve cognitive or developmental challenges, cerebral palsy specifically relates to motor function. Intellectual disability pertains to cognitive limitations, epilepsy involves recurrent seizures due to abnormal brain activity, and Down syndrome is a genetic condition primarily affecting physical characteristics and cognitive development but not directly related to muscle control in the same manner as cerebral palsy. Thus, the unique connection of cerebral palsy to muscle control problems makes it the correct answer.
