Pediatric HIV Linked to Reduced Auditory Cortex Activation Despite Normal Hearing

While combination antiretroviral therapy has significantly improved survival rates for children with perinatally acquired HIV, neurodevelopmental delays and neuroimaging abnormalities remain prevalent in this population [1]. Chronic HIV infection in the central nervous system can lead to persistent neuronal dysregulation (a disruption of normal nerve cell signaling and function) and compromised neurocognition despite pharmacological management [2]. Clinicians frequently observe deficits in attention, executive function, and memory, yet the underlying neural mechanisms driving these specific sensory and cognitive vulnerabilities are not fully understood [1]. Establishing objective biomarkers (measurable biological indicators of a disease state) through neuroimaging is essential for identifying children at risk for long-term academic and social difficulties [2]. A recent study now provides a detailed analysis of how the central auditory system processes sound in these patients, offering a potential explanation for hearing-related challenges that occur in the absence of overt peripheral hearing loss.
