My Mom is 78 her only two medications are thyroid meds (has been checked recently) and Zegerid for GERD. She was diagnosed with Normal Hydrocephalus and had shunt surgery and is doing extremely well. Recently she had severe vertigo. They did a CT and it was normal. No shunt issues, everything looked great. Since the middle of the summer family has noticed some strange behavior, paranoia and severe anger. She was taken to the family doctor who has placed her on Seroquel. That was this past Wednesday. Mom lives with my Dad who is mobile but has many health issues. Dad nor Mom are talking about any of this. There are 6 children and 3 are out of state. My question is can anyone suggest how to move forward from here? How long does it take for Seroquel to work. She is very very sensitive to medication so they have started her on a low dose of 25mg. We would like to support Mom and Dad but are unaware on how to do that when neither one is discussing this with family. Any thoughts would be helpful.
