title: [Psychosis Associated With Fahr's Syndrome: A Case Report].
abstract: BACKGROUND
  Fahr syndrome (SF) is a rare neurological disorder, characterized by abnormal deposition of calcium in brain areas that control movement.
  
  
  OBJECTIVE
  The case is presented of a 41-year-old female with a convulsive syndrome, psychotic disorder, neurocognitive disorde,r and intellectual disability associated with bilateral brain calcifications and altered calcium/phosphorus metabolism in the context of hypoparathyroidism.
  
  
  METHODS
  Case report.
  
  
  RESULTS
  The calcifications found in the patient could be the cause of psychotic symptoms and cognitive impairment. Diagnostic imaging, laboratory tests, psychiatric and neuropsychological assessments are presented. The clinical presentation of this case is compared with similar ones reported in the literature. Therapeutic approaches and clinical outcomes are described.
  
  
  CONCLUSIONS
  Fahr's syndrome should be suspected in patients with neuropsychiatric disorders and seizures. Neuroimaging studies, and the determining of phosphorus and calcium metabolism and parathyroid hormone levels are important in this type of patient.
