I work as a publicist, and recently, a female psychologist client I work with became forgetful about recent work we did. When I tried to get paid for the media placement she became hostile, combative and said she never gave quotes for that story. I tried to get it resolved but then I began to think she is suffering from dementia or Alzheimer's. She is 74 years old, and I am alarmed and do not know if I should contact her son because I am concerned about her mental state and her welfare. Am I wrong to do nothing?
