The focus is always on translating basic scientific insights into new diagnostic tools and disease-modifying therapies that offer hope to patients and their families.
Neurodevelopmental and Psychiatric Disorders: Shaping Minds from Early Life
The brain’s development from conception through adolescence is a remarkably complex and vulnerable process, and disruptions can lead to a spectrum of neurodevelopmental and psychiatric disorders. Emory’s neuroscience labs are dedicated to understanding the origins and mechanisms of conditions such as autism spectrum disorder (ASD), schizophrenia, depression, anxiety disorders, and addiction.
Research in this area often begins with early life experiences and genetic predispositions. Scientists investigate how genetic mutations, environmental factors, and gene-environment interactions shape neural circuit formation and function. Using advanced imaging techniques, they map the structural and functional connectivity of the developing brain, identifying subtle differences that may predispose individuals to certain conditions.
For ASD, labs explore the intricate social and communication deficits, investigating synaptic dysfunction and neuronal network imbalances. They are identifying potential biomarkers for early diagnosis and developing targeted interventions, including behavioral therapies and pharmacological agents, to improve outcomes. In the context of schizophrenia and depression, researchers are unraveling the complex interplay of neurotransmitter systems, inflammation, and stress responses, seeking to identify novel drug targets and personalized treatment strategies. The addiction research program, a vital component, delves into the neural circuits underlying craving, relapse, and compulsive drug-seeking behaviors, aiming to develop more effective prevention and treatment modalities for substance use disorders.
Stroke, Epilepsy, and Neurological Injury: Restoring Function and Preventing Damage
Acute neurological events like stroke, epilepsy, and traumatic brain injury (TBI) can have devastating and lasting consequences. Emory’s neuroscience labs are committed to understanding the mechanisms of neuronal damage and developing strategies for neuroprotection, repair, and rehabilitation.
Stroke research focuses on both acute interventions to minimize damage during the immediate aftermath of an ischemic event and long-term strategies to promote neuroplasticity and recovery. Scientists investigate novel reperfusion strategies, neuroprotective compounds, and methods to enhance brain repair processes. This includes exploring the potential of stem cell therapies and innovative rehabilitation techniques to restore motor and cognitive function.
In epilepsy, researchers are working to identify the aberrant neural circuits that give rise to seizures.
