louann,

Here is another link for you to check out.

Was your son argumentative before his injury? Sometimes, a behavior that pre-existed a brain injury becomes magnified by the injury.

The Dept of Mental Health may have some ideas. It sounds like he needs a lock-down mental health facility. At his and your age, he should not be your burden except you being a visitor and maybe legal guardian. By mental health standards, he is gravely disabled and unable to provide for his won care. That justifies a mental health commitment.

Here is another link for Adult Protective Services. It may be more appropriate than Dept of Mental Health

I know how hard it is to consider having him committed to an institution but you are too old to carry this burden. It will wear down on your health and then he will have nobody. If he can be placed in a care facility, at least you can have an influence on his care and visit him. I have watched my mother and my mother-in-law care for husbands with damaged minds (dementia). It is an exhausting job. It can take a decade or more off your life expectancy.

Has anybody started a Social Security Disability Income application for him? He would likely qualify for expedited approval. There are attorneys who specialize in getting SSDI applications approved. They are in the yellow pages under Attorneys/Social Security or Disability.

My best to you.
