Hi @HavanaS,
So sorry to hear this, this must be an awful time for you and your mum. I can see that you’ve already commented on similar thread (Delirium after admission to hospital) where other people have shared a similar issue. I’d definitely raise your concerns with your mum’s specialist because as you’ve suspected, it may be linked to her medication.
Of course, you can always give our helpline a call and speak to our advisers who have a lot of knowledge and experience on hallucinations and delusions so do give us a call on 0808 800 0303. Lastly we have a lot of useful information on our website on hallucinations and delusions which you can find here - Hallucinations and delusions - as a symptom | Parkinson's UK.
I hope you find this information useful.
Best wishes,
Reah
