I am 70 years old and my wife has dementia. She has recently become more and more aggressive, both verbally and physically. Are there any emergency responses available other than the police ? She has never really hurt me physically but I fear it will happen soon. The physical side manifests itself mainly by her throwing things around the flat and also at me. Background info is that her first small signs began about 4 years ago and she was diagnosed about 4 weeks ago. Neither of us have any family or friends available to help.
