I care for my 86 year old Mum who has vascular dementia. She currently has a toilet obsession and spends a lot of time in the bathroom. She has been having severe panic attacks, complaining of central chest pain and saying she cannot get a full breath. We had previously called an ambulance to be told her heart is ok and it is down to panic. She has started getting worse and not listening when I try and calm her gently and can end up shouting and screaming and pushing me away. She takes medications for anxiety and depression and pregablin has now been prescribed. Has anyone else experienced this and have any tips for dealing with it ? Thank you.
