Corticospinal tract involvement in the motor dysfunction of adult-onset type 1 myotonic dystrophy

Takeaway

  • Reduction of gray matter volume in the sensorimotor cortex likely affects motor performance in people with myotonic dystrophy type 1 (DM1).

Why this matters

  • The involvement of the corticospinal tract (CST) may play a key role in clinical myotonia.
