Thank you for posting your query.
I agree with you that coughing up blood is not linked to Parkinson's disease (PD).
I also agree that PD is an untreatable disease, without any cure. However, death is uncommon if patients are looked after well.
Coughing up blood is either due to chest/lung infection
or cancer. A chest X ray
and CT scan
of the chest would be useful. Please also get him checked up by a Chest physician.
I hope it helps.
Please get back if you require any additional information.
