How to handle Senior citizen anxiety and paranoia? Looking for guidance... Thank you.

How old is the person in your care? Is the anxiety recent (last few months) or was this person always a nervous, distrusting person?

Have you scheduled/encouraged this person to be examined by a doctor and requested a full blood panel and urinalysis as part of the examination?

Has anyone besides you noticed changes in the person’s demeanor/attitude/emotional reactions?

Has the person for whom you care experienced or initiated a change in personal routine/daily habits/personal care?

Too little information. Can you share more about your mother's condition?
