My husband with Alzheimer's disease came back from 3 days psychiatric unit last year and had to continuously take resperidone. I noticed the side effects, such as declining the abilities of writing, reading and speaking, along with muscle stiffness and weakness. It took me to convince his medical team to stop the medicine. My husband is no longer able to read, write and speak well as he used to be. Recently, I have noticed he becomes very difficult to speak, like aphasia, when his left eye shows in red. His speech improves a little, and then same thing has happen. He has high blood pressure, high cholesterol with diabetes, and occasionally shows low kidney function. Recently, his blood pressure sometimes becomes very low. I wondered if he has mini-stroke. let me know.
