Eligibility
You can get Attendance Allowance if you’ve reached State Pension age and the following apply:
you have a physical disability (including sensory disability, for example blindness), a mental disability (including learning difficulties), or both
your disability is severe enough for you to need help caring for yourself or someone to supervise you, for your own or someone else’s safety
you have needed that help for at least 6 months
There are different eligibility rules if you’re nearing the end of life (for example, due to a life-limiting illness). You might be able to get Attendance Allowance more quickly and at a higher rate.

Assuming you are a UK resident, you will definitely qualify.
