Prior to C/L low dose 25/100 (from 1 to 2 a day, then to 3 a day then back to 2 and now 1 daily) "only" symptoms were gait and balance instability, bent posture, very slight unnoticeable tremor in one hand, fatigue and anxiety. Since starting this C/L ..it's not the extended release...my husband has begun experiencing increased anxiety and memory issues. Had one hallucination on the dose of 3 so neuro brought down to 2. Husband skipped 3 doses in a row and when realized he resumed the usual 2 a day regime immediately (without working back up to it, starting with 1. ) He had extreme confusion and a jump in blood pressure. Neuro said to bring down to one a day for 5 days and then to stop it for two weeks to see if confusion ends. Fearing to stop it altogether, because it has helped his initial issues we brought it down to the one and monitored closely. He was much, much better. So we did not stop it altogether. He has been on the one C/L now for 18 days. Yesterday I was speaking to him, albeit from another room and he did not answer so I went closer ( He was in process of working a newspaper puzzle) and repeated myself. After the 3rd time I got his attention and he said he heard me before but it sounded like I was talking to two ladies...we were in the house alone together... he didn't say if he thought I was on the phone in the other room or whatever. Is this a hallucination? Most of what I read in this forum deals with the motor issues. I need some guidance from you because I feel you know best. There is no substitute for experience. I read here about the supplement for treatment and will pursue that avenue soon. It's very confusing. I am hesitant to speak to neuro about it fearing he may poo poo the idea. Husband has lost 25 pounds over past 2 1/2 years and we began seeking help with that one problem. No one has figured it out. Endo bloodwork is coming soon, followed by appt for results. Initial appt was a thorough exam. We can deal with the PD issues, but this memory stuff that was not there prior to starting the C/L is upsetting for both if us. He is aware of the change in himself. Thanks to all of you for any help and you are in my prayers.
