Sensory and Motor Deficit Cases Flashcards
Likely to be corticospinal and corticobulbar tract fibers below cortex and above medulla on the contralateral side
Unilateral face, arm, and leg weakness or paralysis with no associated sensory deficits
Likely to be entire primary motor cortex, including face, arm, and leg representations of the precentral gyrus, or corticospinal and corticobulbar tract fibers above the medulla on the contralateral side
Unilateral face, arm, and leg weakness or paralysis with associated somatosensory, oculomotor, visual, or higher cortical deficits
Likely to be arm and leg area of the motor cortex
Likely to be corticospinal tract from the lower medulla to the C5 level
- Motor cortex or medulla: contralateral side
- Below pyramidal decussation: ipsilateral
- Cortical lesions sparing the face usually affect proximal more than distal muscles
- Anterior cerebral or middle cerebral watershed infarct, lateral trauma, MS
Unilateral arm and leg weakness or paralysis
Likely to be arm area of the primary motor cortex, on the contralateral: small cortical branch of the MCA
Likely to be peripheral nerves supplying the arm, ipsilateral: compression injury or diabetic neuropathy
Unilateral arm weakness or paralysis (brachial monoparesis)
Likely to be leg area of the primary cortex (contralateral)
Likely to be lateral corticospinal tract below T1 (ipsilateral)
Likely to be Peripheral nerves supplying the leg (ipsilateral)
Unilateral leg weakness or paralysis
Likely to be facial nerve (CN VII)
Unilateral facial weakness or paralysis: Bell’s palsy
Likely to be genu of internal capsule or face area of primary motor cortex
