Dave and Tina , our dementia experience

My name is Dave and I am the full time caregiver for my wife Tina who is suffering with Frontal Lobe Dementia. Tina is in her later stage and I have to tend to all her needs. Tina is 57 years old and was diagnosed in 2006. The last year has been very trying for me and her. She is not able to talk , feed her self, bath , dress and is incontient. The last month or so has been difficult she is experiencing hallucinations and it is putting a lot of stress on me.

I am looking for tips and advise on how to dealing with this problem.
