Core Tip
Core Tip: Mills’ syndrome is an extremely rare degenerative motor neuron disorder, whose nosological status is currently uncertain. We report 3 cases with similar features as those described in Mills’ original paper. All patients had initial symptoms in one lower extremity that spread up to the homolateral upper limb, followed by the contralateral lower limb, and finally the contralateral upper limb. It is necessary to clarify the clinical features to receive more attention from clinicians.
