<human>: My husband has been actively completely out of character over the past week and has been paranoid, anxious and delusional. It was so sudden that I asked for health checks including a brain scan which was refused. I cannot leave him alone and now I m waiting for a psychiatric referral. Now for the fourth time in two days he has complained of a burnt toast smell. I ve just searched this and it suggests a brain injury. Is this true?
<bot>: There are few things which I may clarify:Delusional disorders are those in which person has delusions pertaining to only one life sphere. Rest of the behavior is normal. Delusion as a symptom can occur in many disorders like schizophrenia, depression, bipolar disorder and some others. But each of these disorders are accompanied by some other features. Burnt toast smell can be a feature of some central nervous system pathology, so can be the delusion. So I would advise you to go for a brain scan (MRI). Treatment will depend on the MRI findings.
