Steven A Castellon

Steven A Castellon is a Clinical Associate Professor in the Department of Psychiatry and Biobehavioral Sciences at the University of California, Los Angeles (UCLA) School of Medicine. His research focuses on neuropsychological aspects of chronic medical conditions, particularly examining cognitive functioning in individuals with HIV/AIDS, breast cancer survivors experiencing cognitive changes, and patients with hepatitis C.

His primary research interests include neuropsychological assessment, medication adherence in chronic illness, cognitive rehabilitation, neurocognitive effects of medical treatments, and the relationship between mental health and cognitive functioning in medical populations. Dr. Castellon has conducted extensive research on HIV-associated neurocognitive disorders, breast cancer-related cognitive impairment (often referred to as "chemobrain"), and the cognitive effects of hepatitis C infection and treatment.

Analysis of his publication record shows a consistent focus on the intersection of medical conditions and cognitive functioning, with particular emphasis on how cognitive impairment affects treatment adherence and quality of life. His work spans multiple methodologies including longitudinal studies, clinical trials, and neuroimaging approaches. The majority of his publications examine how medical conditions and their treatments impact specific cognitive domains such as memory, attention, and executive functioning.

Dr. Castellon has collaborated extensively with researchers at UCLA and other institutions, particularly working with Patricia Ganz, April Thames, Mark Ettenhofer, Andrew Levine, and Daniel Silverman. His work has been published in high-impact journals across multiple disciplines including neurology, oncology, psychiatry, and clinical psychology.

In his clinical work, Dr. Castellon appears to focus on the neuropsychological aspects of medical conditions, particularly addressing cognitive complaints in patients undergoing medical treatments. His research has contributed significantly to understanding the cognitive effects of cancer treatments, HIV infection, and hepatitis C, and how these cognitive changes impact patients' daily functioning and treatment adherence.
