My husband is 73 years old and has been taking Sertraline HCL 25mg since 8/28/18. He has Parkinson's Disease, neurocognitive disorder and experiences frequent dizziness. In the past month, he has a hard time keeping awake during the day, but is up and down all night long, saying he feels anxious and crowded. He also has experienced more frequent and more serious dizziness. Since Sertraline is his most recent new med, I am wondering if that could be the cause of the recent problems and behavior.
