Proton pump inhibitors (PPIs) are widely used in gastrointestinal disorders and are generally considered safe by clinicians. However, it is unusual side effect of hypomagnesemia is potentially under-recognized. Delirium is usually thought to be a clue of cerebrovascular disease, and the association between delirium and hypomagnesemia is unexpected. We describe a patient used PPI with hypomagnesemia showed normal parathyroid hormone (PTH) despite hypocalcemia and reversible delirium. To enhance clinicians\u2019 vigilance, we performed a literature review on cerebellar syndromes due to hypomagnesemia.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Patient concerns:<\/jats:title>\n            <jats:p>A 74-year-old woman was admitted to our hospital with intermittent nausea, vomiting, hand tremors, and delirium.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Diagnosis:<\/jats:title>\n            <jats:p>Laboratory analysis showed hypokalemia, hypomagnesemia, and normal parathyroid hormone despite hypocalcemia, physical examination showed horizontal nystagmus and the brain MRI was negative.
