Seeing animals and people in yard, hearing them at night, no signs of dementia. Reason?
Patient: My Mother, age 79, has started seeing animals and people in her yard.  The animals she describes as strange looking and the people are wearing brightly colored clothing.  That escalated to her hearing them at night on the roof and now she thinks they are trying to look in her windows.  She has seen a neurologist and had a chemical analysis of her blood run, an MRI of her brain, a chest xray, a CAT scan and now we are wondering where else to turn.  She has no signs of dementia like forgetting people or what she last ate etc.  What can this be? Doctor: Hello,What she is experiencing could be Visual hallucinations and Auditory hallucinations. A patient experiencing hallucinations start hearing voices or seeing things / visions which are not there.Hallucinations may occur in neurological illness as well as psychiatric illness like psychosis and respond well to antipsychotic medicine like Olanzapine, Aripiprazole, Quetiapine etc. In my view, she should be seen by a psychiatrist also to rule out any psychiatric illness.Kind regardsVikas
