Hello! Welcome and thank you for asking on HCM! I understand your concern and would explain that high blood pressure in her situation should be treated like in other patients. You should know that high blood pressure is not typical of Parkinson s disease (it usually causes hypotension or orthostatic hypotension). I would like to know what is her actual antihypertensive therapy. I would recommend consulting with her attending physician for a careful physical examination, a resting ECG, chest X ray study and some blood lab tests (complete blood count, PCR, sedimentation rate, thyroid hormone levels, kidney and liver function tests, blood electrolytes, etc.) to exclude other secondary causes of high blood pressure. You should discuss with her doctor on the possibility of adding other antihypertensive drugs to her actual therapy or increase the doses of the drugs she is taking. I also recommend some lifestyle modifications like diet modifications (avoiding caffeine intake and salt intake) and perform regularly physical activity (walking, etc.). Hope to have been helpful! Greetings! Dr. Iliri
