Hello
@Kathleen s and welcome to the Dementia Support Forum. I am sorry to read about your dad, it must be so difficult to try to care for him from a distance.
I think that the first thing that you should do is to arrange a needs assessment for your dad and possibly a carers assessment for yourself by contacting your local adult social services. I have attached a link below as to how you would go about this.
What are care assessments and how can people with dementia and their carers access them? This information is for care and support in England.

It is also a good idea to ensure that the various legal issues are sorted, such as updated wills and Power of Attorney for both finance and health, these need to be done whilst the person has the capacity to understand what they are signing.
Your dad might also be entitled to Attendance Allowance, and again I have attached a link about this.
Attendance Allowance helps pay for your personal care if you've reached State Pension age and are disabled - rates, eligibility, apply, claim form AA1.

I hope that this helps a little, it is always hard to know what to do following a diagnosis of dementia so please keep in contact with us if we can help in any way.
