Hello docs. i was wondering can thyroid cause hallucinations?

Yes: It is known that changes in thyroid hormone levels could lead to manic or psychotic states that would promote the development of hallucinations and hallucinatory experiences related to a deterioration in thought processes, mood and potentially the onset of delirium. Be sure to get checked out and stay safe!

Thyroid: Toxic thyroid can occasionally do so. Talk to your doc.
