You might want to ask his doctor if Bill’s anger has to do with waking up or bedtime and see if he has any suggestions.
I found this interesting article about Dementia and something we may not know about if our loved ones haven’t been tested:
What's LATE?

In LATE, a protein called TDP-43 (which stands for transactive response DNA binding protein of 43 kDa) accumulates in brain cells. Once it accumulates, it injures and ultimately destroys the cells.

LATE generally damages many of the same areas affected by Alzheimer's disease. These regions include:

the amygdala, involved in emotional regulation
the hippocampus, involved in learning and memory
the temporal lobe, involved in words and their meanings
portions of the frontal lobes, involved with keeping information in mind and manipulating it.
What are the symptoms of LATE?

Because LATE affects many of the same brain regions as Alzheimer's disease, it often presents with similar symptoms, including

memory loss (impairment in episodic memory)
trouble finding and understanding words (impairment in semantic memory)
trouble keeping information in mind (impairment in working memory).

How common is LATE?

By itself, LATE is estimated to cause about 15 percent to 20 percent of all dementias. Many people with dementia also have LATE pathology in addition to one or more other pathologies in their brain. For example, an individual may have the plaques and tangles of Alzheimer's pathology, plus LATE pathology, plus ministrokes (vascular pathology). It turns out that about 40 percent of people with dementia have at least some LATE pathology in their brain. All of this means that LATE is, indeed, very common.

How is LATE diagnosed, and why haven't you heard of it before?

LATE can only be diagnosed with certainty at autopsy. However, we can get a hint that LATE might be present when an older individual shows the memory loss and word-finding problems common in Alzheimer's disease, but special tests used to confirm the diagnosis of Alzheimer's come up negative.

The reason that you—and most clinicians—haven't heard about LATE before is that we didn't realize just how common it is. It was only when we began obtaining results of special tests to diagnose Alzheimer's disease in living individuals (such as with a lumbar puncture or amyloid PET scan) that we began seeing the prevalence of LATE.

Can LATE be treated?

Because LATE was (and still is) often confused with Alzheimer's disease, it is almost certain that when the main drugs that are FDA-approved to treat Alzheimer's disease were evaluated, individuals with LATE were included in those studies. This means that there is every reason to believe that drugs like donepezil (brand name Aricept), rivastigmine (Exelon), memantine (Namenda), and galantamine will all be effective for individuals with dementia due to LATE.

How can you find out more about LATE?

There has been an explosion of scientific papers about LATE in just the last few years. If you have a science background, you might want to peruse them or watch the wonderful scientific symposium on this disorder held by the National Institute on Aging (NIA). If you don't have a science background, take a look at the NIA or Wikipedia pages on LATE.

I've never heard of LATE - thank you for bringing to my attention.

I am keeping a journal so I can remember things to ask or bring to the doctor's attention.
