Hello,
As his age is 80 and
dementia it is but obvious to a conclusion I feel that the venous return is reduced and due to which he has swelling of the lower
limbs. The first thing to do is, when he is lying in bed keep the legs over the pillow. Next use the
diuretic prescribed by the physician.
If possible then get the urine and blood routine get tested to check if any infection is bothering. Coming to the part of
scrotum getting swollen it needs an examination. It may happen if there is any
urinary retention or infection. A physical examination will be of benefit.
As he is 80, he needs a passive
physical therapy and later on actions to improve the overall physical activity levels by which he can get active.
There was a recent research article in 2019, which states that exercise helps reduce dementia and also improve the overall abilities to conduct the ADL.
I will recommend getting the scrotum physically examined by the physician, next blood and urine test, next diuretic and stockings. and most important need is of physical therapy.
In my 12 years of experience, I have noticed that even at the age of 90+ most patients are benefitted with physical therapy and improved their ADL (activities of daily living).
Hope I have answered your query. Let me know if I can assist you further.
