    • Temporary 
    • AOS, aphasia, cognitive problems (UUMN less functional importance)
  3. UUMN is typically caused by a small lesion sometimes not evidenced on imaging especially early on. May be only evidence of neurologic disease. What is the predominant cause?
    • CVA
    • small portion: traumatic, neurosurgical resections, tumor
  4. UUMN often occurs w/ aphasia or AOS when lesion is in ___ cerebral hemisphere. Common causes include occlusions where? (3) Can occur w/ cognitive deficits when in ___ hemisphere

  6. UUMN is primarily a disorder of ____. Impaired speech production related to (3). Severity ranges from mild to moderate.
    • Articulation
    • weakness, reduced ROM, decreased fine motor control of lips and tongue
  7. Phonation and UUMN dysarthria?
    Prosody and respiration?
    • mild to moderate harsh vocal quality 
    • hypernasality; UUMN lesion alone should result in only mild hyper nasality
