My husband recently had his first covid vaccination. Since then there has been marked deterioration in his behaviour with more hallucinations. Prolonged periods of distress and agitation, and confusion. I appreciate that doctors will say this is just a progression of his Alzheimer’s. But I just wondered if anyone else has seen similar reactions. I am really distressed now and exhausted as so difficult to cope with. He has had the condition for 10 years and we have dealt with all the various symptoms but nothing on this scale. Take care all.
