Neurologist & Sleep Medicine Specialist — Snorple Scientific Advisor
Assistant Professor, Neurological Sciences • Universidad de Chile, Departamento de Ciencias Neurológicas Oriente • Chile
Dr. Rodrigo Salinas Ugarte is a Chilean neurologist and sleep medicine specialist affiliated with the Departamento de Ciencias Neurológicas Oriente at the Universidad de Chile — one of Latin America's most distinguished academic neuroscience programs. As Assistant Professor in the Department, he combines active clinical work in neurology with a sustained research program that spans sleep disorders, cerebrovascular disease, and the neurological consequences of sleep-disordered breathing. His academic output reflects the depth of that commitment: 62 peer-reviewed publications and 1,782 citations on ResearchGate, a record that places him among the more productive clinical neuroscience researchers in the Southern Cone region.
Sleep medicine occupies a central position in Dr. Salinas Ugarte's clinical and research identity. His neurological training gives him an unusually complete view of why sleep-disordered breathing matters: the brain is not a passive bystander during obstructive events, but an active participant in the pathophysiology. Each episode of partial or complete upper airway obstruction — whether manifesting as primary snoring or diagnosable obstructive sleep apnea — produces measurable neurological consequences: cortical arousal, sympathetic activation, impaired glymphatic clearance, and, over time, structural changes in white matter and vascular territories associated with cerebrovascular risk. Dr. Salinas Ugarte's work in cerebrovascular disease connects directly to this: stroke and transient ischemic attack are meaningfully more common in populations with untreated sleep-disordered breathing, and the causal mechanisms are now well established in the neurological literature.
His perspective on snoring treatment is rooted in this neurological framework. Oral appliance therapy — specifically mandibular advancement devices and tongue stabilizing devices used in combination — represents the first-line conservative intervention for primary snoring and mild-to-moderate OSA that is both evidence-supported and accessible to patients who cannot tolerate or do not require CPAP. Dr. Salinas Ugarte brings the Chilean and broader Latin American clinical context to this conversation: a population in which sleep disorders are significantly underdiagnosed and undertreated, and in which accessible, patient-friendly interventions can meaningfully close that treatment gap.
PROFESSIONAL ENDORSEMENT
"From a neurological standpoint, the consequences of untreated sleep-disordered breathing extend well beyond fatigue. Recurrent nocturnal hypoxemia and cortical arousal impose a measurable burden on cerebrovascular health over time. Conservative oral appliance therapy — particularly combined MAD and TSD approaches that address both mandibular position and tongue displacement — offers an evidence-based, patient-tolerable intervention that can meaningfully reduce this burden. Getting patients into effective treatment early, before structural neurological changes accumulate, is a clinical priority that the neuroscience fully supports."

Addressing the significant underdiagnosis of sleep disorders in Chile and the broader Latin American clinical context.
"In neurology, we are trained to think about what the brain requires to function well and what threatens those requirements. Sleep is not optional for the brain — it is the period during which metabolic waste products are cleared via the glymphatic system, memories are consolidated, and the vasculature recovers from a day of activity. When snoring fragments sleep or produces oxygen desaturation, those processes are disrupted. Over years, the cumulative effect on cerebrovascular health is real and measurable. I approach snoring not as a social inconvenience but as a modifiable neurological risk factor. Combined oral appliance therapy that simultaneously advances the mandible and stabilizes the tongue represents a practical, well-tolerated solution that addresses the anatomical contributors to obstruction. For the majority of patients with primary snoring or mild-to-moderate OSA, it is exactly the kind of accessible, evidence-backed intervention that can make a difference before the condition progresses."
