Hi ToeJoe
Although I'm unable to help your friend out personally by assisting with care I also have a friend with Parkinson's and thought I would do some searching for you to see what resources might be in your state - Ohio. Unfortunately I don't think I can provide direct links as I think they're likely to get edited out but if you search these particular topics you might get some leads. I understand the need that the support be FREE - I'm not sure if they are but maybe by asking they could direct you to other places they know about. Also if they don't already belong to a local Parkinson's Support Group joining one may be a good source of information. Good luck

I came across this which has some info which may be useful:
Sourced from Parkinson's News: Volume 34 Issue 11 November 2014
National Parkinson's Foundation: www.parkinson.org/caregivers.
In addition to the resources through NPF, our Ohio chapter offers support groups specifically for the caregiver. They are part of the support group listing beginning on page 6 of this newsletter. In addition to contacting our office (614.890.1901), the NPF provides a Helpline staffed by specialists with social work and nursing backgrounds Monday – Friday, 9:00
a.m. – 5:00 p.m. in both English and Spanish by calling 1-800-4PD-INFO (1.800.473.4636) or emailing questions to helpline@parkinson.org.
In support of providing care for the caregiver, our Chapter has some limited funds still available through the Family Caregiver Relief Fund, [/B]a program made possible through a grant received from NPF as a result of the money raised through Moving Day®. Please contact me for additional information by calling the office (614.890.1901) or email to ddavis@centralohioparkinson.org

Others:
Disability Rights Ohio: (disabilityrightsohio.org) this provides information on right of access to respite care. There are four highlighted links on their home page - I haven't read all of them but the 4th one links to "healthguide.org" which if you read down far enough has info on entitlements and how respite care can be funded.
