<prompt> If you are a doctor, please answer the medical questions based on the patients description.My mother is 85 years old. She is been using Concor Cor 2.5 mg for the last five years. Recently she is been very forgetful , well something runs in her family around that age. Recently she is suffering some sort of waves of hallucinations . The hallucination periods seem to start or and intensify after taking Concor. I ve been watching her for a while to reach such assumption . She does not suffer from anything else but her heart problem. She also uses Lasix . Lasix 40 mg not a daily dose nor a whole dosage, something to be decided by her care giver.I m VERY concerned about the confusion hallucinations waves she is suffering. Please advice. Thanks  <response>: Hi there! Looking at the patient profile, what you have give, I can strongly think the possibility of Dementia, which presents like this.i dont see a strong connection with Bisoprolol i.e. Concord 2.5 MG.I would suggest you to get her evaluated by a psychiatristneurologist, for Dementia and behavioral disturbances associated with it, medicines can definitely benefit her and can slow down the process of same.
