As you said she is suffering from a mental disorder of chronic nature (6 Years or more) with initial symptoms of Irrelevant talks (Shouting ), Auditory hallucination
(Hearing voices) and Paranoid ideation (Somebody will crab me). Her condition deteriorated despite psychotropic treatment for last 6 years. Now she is having Poor self care with Resistivity & Emotional blunting.
Well, the case description fits
into the mental illness called schizophrenia
(?). Schizophrenia with prominent negative sign & symptoms is very difficult to manage but once her symptoms comes under control she will remain well adjusted to her social condition for long duration of time, off course with continuing drug therapy.
Available options for her include ....
 Second generation anti-psychotic (like quetiapine
, paliperidone etc) either alone or in combination with other first/ second generation anti-psychotics targeting specifically her negativity & resistivity
 Electro convulsive therapy (ECT)
 Hospitalisation for short duration of time (If needed)
 Behavioural Therapy
Schizophrenia does not have so much gloomier picture as you have develop perception about this illness. As I said, once the symptoms are under control by the use of appropriate psycho-pharmacological intervention, she will remain well for long duration of time. What is needed is a dedicated & comprehensive effort from treating psychiatrist
& care taker.
