Care takers for Dementia patients - Mysore

Hi, it's been a few years since my dad has been diagnosed with dementia and the doctors have said it's progressing quite fast. I have been on the lookout for caretakers to help my mom ( I stay in a different country) but it's been really hard to find someone who understands the nature of care dementia people require and to help out with that. Any suggestions would really help me and also any leads on day care centres or rehab centres for dementia people in Mysore would really help me. Trying to do this remote ans any direction would really count as a blessing.
