There is a good chance my father’s “balance and speech” issue was from an overprescribed amount of Galantamine by an incompetent Primary Care Doctor and a Vitamin B and folate deficiency per his history of low platelet count.

Per FDA Guidelines the max daily should not go over 24 mg especially for the elderly.
