My mom is 89 diagnosed with minor normal dementia then developed a blot clot...given xarelto....couple months later is now hallucinating. No other med changes for may years. Does take small amounts of Ativan for myoclonic tremors but has for 5 years with no issues. Takes Toprol, Lipitor, midodrine and a few others, but again has had all for many years without issues. Your thought please on the xarelto causing the hallucinations. They seemed to start overnight almost.
Xeralto don't cause hallucinations. Dementia in this case needs to be typified.  In view of age and hallucinations and myoclonic jerks, I would lie to rule out Dementia with Levi body (DLB)consult a neurologist and get him examined.u can start tab rivastigmine for forgetfulness.
