My mother is 87 years old and has recently been exhibiting signs of memory loss, specifically of basic daily tasks, such as using the oven or the stove, and frequently visited areas seem unfamiliar to her. She has been given a low dose of donezipan. Yesterday she was off balance and fell. Although she experienced some dizziness before this medication, I was wondering if she may not be tolerating it well. She also has hypertension for which she takes Lisinopril 1x day, Vit D and B12. We are awaiting a full memory study in October, but in the meantime I am concerned about this medication. Your thoughts???
