  1. Things to check on neurologic exam
    • Mental Status
    • Cranial Nerves
    • Motor
    • Sensory
    • Cerebellar
    • Reflexes
    • Gait

    MR MC GCS
  2. 3 things to check on mental status
    • Level of Consciousness (LoC)
    • Speech (dysarthria) and language
    • Memory
  3. When testing sensory Always test from
    Area of poor sensation to a region of normal or more normal sensation
  4. Romberg, DSS test
    Sensory
  5. UMN vs. LMN:
    Weakness
    Spasticity
    Hyperreflexia
    Clonus
    Spasms (most often flexor)
    UMN
  6. UMN vs. LMN: 
    Weakness
    Flaccidity
    Hyporeflexia
    Fasiculations
    Atrophy
    LMN

    *Note UMN initially produces flaccid weakness
  7. Hemiparesis:  Lesion location
    • Cortex, subcortex or brainstem
    • Lesion is opposite weak side
  8. Follows hemiparesis
    Facial weakness

    (If above pons, expect sparing of upper face and weakness on same side as body weakness)
  9. Lesion localization:  Loss of vibration proprioception
    Posterior column (spinal cord)
  10. Lesion localization:  Loss of pain/temp
    Contralateral ALS
  11. Lesion localization:  Loss of sensation on side opposite weakness
    Brainstem
  12. Lesion localization:  Loss of all sensory modalities on one side
    Thalamus
  13. Lesion localization:  Weakness/sensory loss on same side
    Cerebrum
  14. Lesion localization:  all modalities affected in dermatome
    Peripheral nerve
  15. Lesion localization:  Distal symm sensory loss
    Polyneuropathy
  16. Cerebellar lesions result in
    Ipsilateral ataxia (they cross 2x)
  17. Waddling gait is result of
    Severe proximal muscle weakness
  18. Lesion localization:  Spastic/scissor gate
    Corticospinal tract lesions
  19. Lesion localization:  Magnetic gait/apractic gait
    Frontal lobes
  20. Cortical vs. Subcortical:  Aphasia, apraxia, agnosia
    Cortical
  21. C vs. S:  Equal involvement of face/arm/leg; sensory abnormalities; visual field cuts
    Subcortical
  22. Homonymous defect can only be
    brain lesion
