Hello thanks for asking from HCM for your health related queries I can understand your concern. She is 60 and is hallucinations and hearing voices. She is also having symptoms like suspiciousness that someone is conspiring against her. Such time of symptoms are not usually seen at her age and need proper consultation and evaluation. You should get her serum electrolytes checked to find out any electrolyte abnormalities to rule out any organic cause. She also should checked for any organic brain abnormality with proper MRI scan of brain. This would rule out any evidence of ischaemic damage to brain. If both conditions are ruled out then most likely the cause of her symptoms is some psychotic episode. If she has history of any recent fever, or trauma or seizures then consult a physician for proper evaluation. In such symptoms medicines like anti-psychotics can help in improvement of symptoms. Medicines like Olanzapine, Quetiapine etc can help to improve her symptoms. Discuss a psychiatrist for detailed evaluation. Thanks, Hope this helps you. Take care
