Welcome @johns92118, Sorry to hear you are dealing with multiple conditions due to agent orange exposure. I'm also a Vietnam veteran but fortunately had no exposure. There may possibly be a connection or link but the one I've seen listed by the VA is birth defects for women Vietnam veterans (Hydrocephalus due to aqueductal stenosis) - Vietnam Veterans: Is Your Medical Condition on the Agent Orange Presumptive List?: https://vaclaimsinsider.com/agent-orange-presumptive-list/.

I did find another reference but it's also related to birth defects:
"In Vietnam, the Vietnamese Red Cross also associates the following with exposure to dioxin: liver cancer; lipid metabolism disorder; reproductive abnormalities and congenital deformities such as cleft lip, cleft palate, club foot, hydrocephalus, neural tube defects, fused digits, muscle malformations and paralysis; and some developmental disabilities."

I'm not sure if you have already seen this but it might provide some answers for you.
--- Agent Orange exposure and VA disability compensation: https://www.va.gov/disability/eligibility/hazardous-materials-exposure/agent-orange/.

Have you talked with or contacted the Veteran's Administration?

I’m dealing with high blood pressure, hydrocephalus, stokes, diabetes, and the onset of Parkinson’s disease in both my father and my uncle. Both were exposed to large amounts of agent orange, one being a paratrooper that jumped right into that fog.

For this, one has to operated for a Shunt. Is there any other method to deal with HS? Any incidents or experience? Pls share any pointers. BR
