My husband is on workman's comp from the Fed Gov't. This means he can't receive help from the VA though he is a Vietnam vet. What to do?

I am in the most rediculous situation I have ever heard of. My husband is on workman's comp from the Fed Gov't. He had a brain injury at 42 related to work.
He now has alz. He is also a Viet Nam vet. The VA offers so much to vets with alz.
But the hitch is , getting his check from the Fed Gov't and getting help from the VA is called double dipping.
Each year we have to fill out a form stating if he got any services from the VA and if he did, the cost of those services will be deducted from his check.
I had a nurse and a social worker tell me we qualify for aid to dependants even with him getting his gov't check. I don't want to lose any of it because we couldn't afford to. I went to a lawyer who told me this was a question for the VA and I needed to get someone there to answer the question for me. I am told the only way to reach the person I need to talk to is to catch him at the VA Hosp because he doesn't answer or take phone calls. Going to our VA Hosp is like going to a zoo. It is nice and care is good but it is just so confusing and I don't want to accept services that I have to have removed from our check. Where do I go from here? If ths confuses you, it confuses me that something would be made so difficult.
