Oh hon, how awful! It's not really your Granddad's fault- his conditions and meds have changed him. I'm afraid that this is one of those situations where things are not going to get better for a long time. I expect that a "not guilty by reason of mental defect" plea will be filed. Hopefully, he will be placed in a secure facility where he can be cared for. It is no longer safe for him to be with family.

The hugest tragedy in this thing is that all of his conditions often respond to cannabis! (The bipolar reaction can be unpredictable- it helps some, makes some worse.) Cannabis prevents amyloid plaques, one of the physical signs of Alzheimer's. It also calms agitation. (click the medical studies link in my sig. Alzheimer's is one of the first topics).

Cannabis MUST be legalized for medical use- tragedies like this don't need to happen! I'm just saying that, if the studies are right, if granddad had used cannabis, he would have had fewer amyloid plaques in his brain, would have been less agitated, would have had fewer Parkinson's symptoms and, perhaps, would have had fewer bipolar problems. (My Mom was bipolar and I have a mild form of it. Cannabis "evens me out". )

Hang in there, hon. And I wish the best possible outcome for you and your family. - Granny:hippy:
