Ginkgo biloba induced mood dysregulation: a case report
Abstract
Background: Impairment of cognitive function as well as negative symptom is the major factor causing the decline of a patient's functioning in chronic stages of schizophrenia. However, until now, there were no definite treatment options that could effectively reduce the impairment.
Case presentation: We report a case of mood dysregulation associated with use of Ginkgo biloba in a patient with schizophrenia. After Ginkgo biloba was given, the patient experienced cluster symptoms of mood dysregulation including irritability, difficulty in controlling anger, agitation and restlessness. We estimated the possibility as "probable" according to Naranjo scale considering circumstantial evidence.
Conclusions: This case suggests that Ginkgo biloba may have caused mood dysregulation in this patient. Although it is generally accepted as safe, more attention should be given to the adverse effect when treating with Ginkgo biloba.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
