20yrs ago, an adult my friend knows had a life changing injury and suffered a head injury. She has no living relatives and my friend have helped her since. Strangely, she is apparently unknown to social services, despite not being able to manage medical/dental appointments, can't manage her finances, can't book appointments etc. She can shop and cook very basic things, or microwave meals and had somehow managed all these years- but with my friends support.
I've suggested contacting social services, to at least get her on their books and see what could be provided. I assume they could review whether she is on the correct benefits, provide support for cleaning, shopping, appointments etc. What other support might be available for someone with a functioning age of maybe a very early teen?
