BDNF and schizophrenia: Increasing research indicates that abnormalities in dopamine and glutaminergic neurotransmission contribute to the development of mental illnesses, while key factors such as brain‐derived neurotrophic factor (BDNF) and NRG1 are implicated in the pathogenesis of cognitive disorders in schizophrenia.[6, 9, 10, 11] However, the precise molecular mechanisms of these factors are yet to be elucidated.
