Does anyone know if I would qualify for any additional state benefits being father's full time care giver?

Hi, sorry to hear about your Dad's ALS diagnosis. I helped a friend with this disease and it is a tough one AND expensive!! If Dad is a veteran, he may qualify for veteran's assistance. Use the search button on this site to see if he qualifies.
Otherwise (in my experience) it is all private pay.
If you aren't already hooked into the MDA / ALS associations near you, do so immediately. The MDA Assoc provides transportation to MDA centers for quarterly visits with the doctor. (No charge). The ALS center near me had a 'loaner closet' where patients could borrow equipment that was needed. I watched my friend go through so many assistive devices in a short period of time and that made me understand the benefit of a loaner closet rather quickly.
I assume your Dad has filed for disability income through social security. Finally, some financial help comes in the form of volunteers or financial help for other than caregiving. Consider all of the friends/neighbors/co-workers/members of a church congregations, etc that your family knows. Be ready to give a suggestion (or two) when someone says 'I wish I could help'. You can respond: Actually it would be a huge help if you could come and spend an hour or two with Dad. That would give me time to do --- grocery shopping, a visit to my own doctor/dentist, etc. You might qualify to get some staples/non-perishables from a local food pantry. Then you use the money you saved by not buying those items to get more care for your Dad. If you can attend an ALS support group in your community, others may have some ideas that worked for them. Let us know if any of this helps. And I am sure others might be able to help too.

My dad passed from ALS last year and I was shocked by the amount of services I was able to dig up (but I had to do a lot of digging). It still never felt like enough, but it was a HUGE help.

-If your dad is going to a special clinic there should be a social worker there. Bug him or her to give you a list of everything you can apply for...aide grants, local/county/state/fed assistance, etc. They'll also be able to provide you with phone numbers for the local loan closets that geewhiz suggested. Those are a life saver when it comes to equipment.

-Definitely get in contact with your local ALS chapter asap (again, like geewhiz said) and make use of the forum that cwillie suggested. I learned TONS from that forum and the chapter was a lifesaver more than once. Many of them offer grants to defray costs.

That's the link for AZ's Home & Community based services, which has a link to find a regional office and more importantly, CAREGIVER RESOURCES. Hook up with your local office to see what they can offer you based on your location/income/dad's diagnosis. For example, here in CT we have a Home Care program where based on income you pay a small portion (roughly 10-20%) of the cost of in-home caregivers for up to 30 hours a week.

-If it's not already in place, ask your dad's doctor for Medicaid covered home-care visits. It has to be re certified every 8 weeks but it will cover 1 RN visit, a couple short CNA visits, PT/OT and RT if he needs it. If nothing else it will give you some respite until you can get some other stuff.

I just rejoined this site so I don't know if there's PMing...if there is feel free to message me if you have any other questions, if not go ahead and ask on here. ALS sucks.

Sheep's response triggered another thought. My friend had a slower version of ALS. She lived for 7 years with the disease. In the later years, I did the research for hospice for her. I called EVERY hospice service that covered our area (many in a heavily populated state.) I was surprised that several of the services said they would provide help as soon as there was an ALS diagnosis! Hospice (in my area) typically provides an aide 2 hours a day/5 days a week. When I interviewed the numerous services, I inquired about other services. The one we selected when the time came, also sent a volunteer to help with other duties --- reading books, writing out greeting cards to send to friends, etc. I don't have to tell Aabrams how much of the day is consumed with helping an ALS patient to do EVERYTHING. Hence, every little bit helps

There is a very active ALS forum at www.alsforums.com, I'm not sure if they have addressed your problem but you may find some other helpful advice and supports there.

Yes thank you geewhiz!! One regret I have is that I did not turn to hospice sooner (and I'm surprised that my father's team didn't suggest it sooner as a resource). The group I used, Vitas (they are in AZ, but of course there's tons and tons) provides an aide, a nurse, a social worker and a spiritual counselor. You should be able to use their services on top of state aid, and all hospice services are 100% covered by Medicare. They will cover prescriptions, in home lifts/transportation, hospital bed, hygiene needs, etc. so it's a HUGE help financially but of course also help with the care as well.

Two of the best things I found with hospice (for my dad, and now my grandmother...and of course this may be different depending who you go with if you choose to go this route now or in the future but I can't imagine too much different): 1, when you call them they come almost right away to get stuff set up and while of course you and your dad have to do some work with paperwork and such, it's not a challenge or a burden. 2, they're 24 hours. If something happens in the middle of the night and you need help, you call. Someone will be happy to come and help you. It doesn't even have to be an emergency, sometimes you're just too tired to do something on your own and you need an extra set of hands, or at that moment its just a little too much to handle. They've got your back.
