Purpose of Seeing a Neurologist after Stroke

Can any of you please explain the benefits of seeing a Neurologist after you've had an ischemic stroke? What can he do that my Primary Care Physician hasn't already done -- now that it's 4 months post-stroke?
I'm 82, have type 2 diabetes, currently in Physical and Occupational Therapy twice a week, and on blood thinner, blood pressure and cholesterol meds, plus Gabapentin for nerve pain in my hand at night. All new meds since stroke. Have first appointment this month, and don't know what to expect...
Thanks for sharing your experience, or whatever you know!
