Had an appointment with dads's neurologist yesterday.  Such an answer to prayer to get an appointment with a memory care specialist at UT Southwestern Medical Center in Dallas.  Uncle Gary came along to help me out with dad.  Doctor ordered new blood work, and EKG and MRI.  We were able to complete the blood work and EKG yesterday.  No results on the tests yet.  Waiting on radiology to call me back to schedule the MRI.
