Abi-Dargham research utilizes molecular imaging techniques (SPECT and PET) to study the pathophysiology of schizophrenia, schizophrenia related spectrum disorders and addiction. Her work has resulted in seminal publications describing the complex alterations of dopamine transmission in schizophrenia and their relationship to clinical symptoms, cognition and response to treatment, as well as their interrelatedness to glutamate dysfunction in schizophrenia. These studies showed increased striatal dopamine release in schizophrenia, which has become one of the most established findings of schizophrenia research, and cortical deficit. Her work with cortical D1 receptors has provided added rationale for developing and testing D1 agonists in schizophrenia. Another direction for work in her imaging group is dual diagnosis patients with comorbid schizophrenia and cannabis abuse. She and her team found that most drug addictions blunt dopamine release during the chronic phase of drug dependence, which results in poor outcomes. In a popular interview, she explained, "The bottom line is that long-term, heavy cannabis use may impair the dopaminergic system, which could have a variety of negative effects on learning and behavior." She has recently focused on understanding the disconnection between striatal and extrastriatal dopamine in schizophrenia and how this contributes to altered perceptual inference, as a key model for hallucinations and psychosis. Ultimately this work is relevant to developing biomarkers and more focused treatment interventions for these disorders.
