1.
How would you characterize this patient’s language
dysfunction? Damage to what area of the brain typically gives
rise to this type of language dysfunction? Indicate the side
of the brain involved.
Nonfluent
aphasia
– Broca’s aphasia.
Posterior
aspect of the left inferior frontal gyrus (areas 44, 45)
2. Considering all of the patient’s signs and
symptoms, indicate the area of the brain involved by the pathologic
process in this case. What specific structures are involved
by the pathologic process?
Posterior
aspect of the
left inferior frontal gyrus (Broca’s area. Areas 44, 45). Adjacent
inferior parts of the premotor area (area 6) and precentral gyrus (primary
motor cortex [PMA], area 4).
3. In general, what type of pathologic process is involved in
this case?
Vascular.
Occlusion of a cortical branch of the left MCA vs a cardiogenic embolus
to
a distal cortical branch of the left MCA in the posterior frontal
region due to atrial
fibrillation.
4. What diagnostic procedure(s) would you undertake at this
point?
