M1 infarcts
(8)
A
- hemiparesis of the lower half of the contralateral face
- hemiparesis of contralateral upper AND lower extremities
- sensory loss from contralateral face, arm, and (some) leg
- ataxia of contralateral extremities (some leg)
- speech impairments like global aphasia if on LEFT side
