What can be done if anything?

My Aunty is 68 years old and has schizophrenia. She lives alone and her condition is gradually deteriorating. She has her meds in a Webster pack but rarely takes them. She has many other health problems and is incapable managing them, let alone perform tasks such as cooking, cleaning or basic hygiene, maintain personal safety.

A few years ago she was admitted to hospital and the staff discussed having her placed in an age care home. Understandably she did not want to go and luckily during the same admission underwent successful ECT enabling her to be discharged home.

I feel like her condition has once again deteriorated to a point that she is unable to care for herself. My mother who is her main support is unable to do anymore for her than she currently does.

What should she do now?

My mother feels she needs to go to age care but can that happen if my Aunty refuses?
