Hello and thanks for your query. I understand that you are very distressed by your mother s deteriorating health condition. People with Lewy Body Dementia often have psychotic symptoms like hallucinations and delusions. Your mother s paranoid beliefs that other people are trying to steal form her are delusions. Her symptom of seeing other people who are not there are hallucinations. Unfortunately, people with Lewy Body Dementia deteriorate with time and their memory, intellectual capability and functioning keep worsening. Soon they may become totally dependent for even day to day activities. So, you need to plan how you are going to take care of her. Unfortunately, this illness is not curable and progressive deterioration is inevitable. So, you have to take care of her yourself or have a carer to take care of her. Since you say that she is already putting herself at risk by wandeting away, continouos care and monitoring is essential. Regards, Dr. Jonas Sundarakumar Consultant Psychiatrist
