Hi Sandra,

Agitation/aggression is one of the most common disturbances in patients with Dementia. I hope these articles could help you:

Hello,

this resource summarises the literature on BPSD including prevalence which seems to depend on the population being studied (in community, residential care etc)

Looking at this from a slightly different angle and to break down your question among dementia subtypes, there is another recent  study published in JAMA which showed a much lower incidence of criminal behavior in AD diagnosed patients as compared to Fronto-temporal diagnosed Dementia patients:

JAMA Neurol. Published online January 05, 2015. doi:10.1001/jamaneurol.2014.3781

Article Criminal Behavior in Frontotemporal Dementia and Alzheimer Disease

Wow! Thank you all, Daniela, Joanne, and Kevin for your incredible responses and links to resources! It is greatly appreciated and I will check each and every one out!  Happy Easter!
