Hello,
As your father has a past medical history of
high blood pressure and was under medication these symptoms are expected for kidneys to malfunction.
Also, there might be lacunar infarct leading to such blood vessel issue. with the blood-thinning medication, he should be fine having control of the blood pressure.
Lasix is given usually to control the high blood pressure and it works well. but if kidneys are damaged then other measures are taken like reducing the water intake.
Coming to the difficulty in reading it happens at a certain age due to neural tissue degenerative changes. having a
neurologist opinion should provide good outcome score.
At 78 we can expect unexpected changes too. I will advise to visit a neurologist and start doing regular exercise in low intensity.
Recent researches have reported that doing 20-30 minutes of low-intensity exercises have helped reduce the blood pressure throughout the day.
Also taking a power Nap will help reduce further the BP for up to 5 mmHg.
Monitor the medications, do regular exercise, monitor the water intake and
diet plan.
Hope I have answered your query. Let me know if I can assist you further.
Take care
