The head of the Alzheimer's Society of Ontario reveals that facilities need to be able to manage patients with dementia, especially after the incidence of death of an Ottawa man in October, when a fellow nursing home resident was charged for his murder.

The incidents of such extreme violence are uncommon, according to David Harvey, President of the Alzheimer's Society of Ontario. He shared that in a few cases, certain prompts can bring about violent behavior in patients suffering from dementia.

Harvey said, "Resident-to-resident violence is something that staff of those facilities has to cope with and be able to manage, [as] it's the course of the disease for a certain number of people".

An 84-year-old, Peter Lee of Ottawa was charged with second-degree murder for killing an 88 year old Frank Moir, on Wednesday. They were the residents at the Peter D. Clark long-term-care home at Meridian Place in Nepean.

The judge ordered a 30-day assessment to decide if the convict is fit for trial, as he has Alzheimer's he has Alzheimer's, according to what the doctors at Lee's court appearance testified.

According to Ontario Government documents, the number of violent incidents between residents in Ontario had tripled from 2003 to 2006.
