Insomnia Combination Treatment: New AASM Guidelines

In this episode of Talking Sleep, host Dr. Seema Khosla welcomes Dr. Daniel Buysse and Dr. Todd Arnedt, both members of the AASM clinical practice guideline committee, to discuss the newly released guidelines on combination treatment for chronic insomnia disorder in adults.

Unlike previous guidelines, this new guidance specifically addresses what happens in real-world clinical practice: patients often request both cognitive behavioral therapy for insomnia (CBT-I) and pharmacotherapy, or arrive seeking medications while clinicians advocate for behavioral interventions. The guidelines provide evidence-based recommendations for navigating these combination treatment scenarios, incorporating patient preferences in ways previous guidelines did not.

The conversation explores the guideline development process, including how committee members were selected and how diverse professional backgrounds enriched the discussion. Dr. Buysse and Dr. Arnedt explain why patient preference wasn't adequately reflected in original practice guidelines and how this updated version addresses that gap.

The first recommendation receives detailed examination: In adults with chronic insomnia, the AASM suggests combination treatment with CBT-I plus medication over medication alone (conditional recommendation, low certainty of evidence). The experts clarify which medications were examined, including whether dual orexin receptor antagonists (DORAs) were included, and explain why evidence certainty is low despite numerous studies. Pharmaceutical sponsorship creates methodological differences—PSG outcomes, fixed time in bed requirements—that complicate interpretation. The high placebo response in insomnia trials adds another layer of complexity.

Critical implementation questions arise: What does "combination therapy" actually mean? Should both treatments start simultaneously, or should one precede the other? Can patients start medications while awaiting CBT-I appointments given typical access delays?

The second recommendation appears paradoxical: The AASM suggests against combination treatment over CBT-I alone, yet recommends combination over medication alone. Dr. Buysse and Dr. Arnedt explain this nuanced position—CBT-I alone remains superior, but for patients who prioritize rapid total sleep time improvement over daytime symptom reduction, combination therapy may be reasonable.

The conversation addresses whether treatment order matters and whether clinical (not just insurance-driven) logic suggests a medication hierarchy—zolpidem before eszopiclone, the role of trazodone, when to consider ramelteon. A crucial question emerges: What about patients who refuse or cannot access CBT-I? How do these guidelines apply when the preferred behavioral treatment is unavailable or unwanted?

Throughout, the experts emphasize that guidelines inform but don't dictate clinical decisions. Patient preferences, values, and individual circumstances must shape treatment plans. The guidelines provide evidence-based frameworks while acknowledging the complexity of real-world insomnia management.

Whether you're treating chronic insomnia, navigating patient requests for medications, addressing CBT-I access barriers, or seeking evidence-based approaches to combination therapy, this episode provides essential guidance.

OSA and Parkinson’s Risk: Can CPAP Change Outcomes?

In this episode of Talking Sleep, host Dr. Seema Khosla welcomes Dr. Lee Neilson, Assistant Professor of Neurology at the University of Iowa and staff neurologist at the Iowa City VA specializing in movement disorders, to discuss his groundbreaking research examining whether obstructive sleep apnea represents a modifiable risk factor for Parkinson's disease.

Dr. Neilson's ambitious study analyzed records from 13 million patients within the VA system to investigate whether OSA is associated with higher risk of neurodegenerative disorders and whether treating sleep apnea might help delay the onset of dementia. The conversation traces the research design from initial hypothesis through methodology, explaining how he narrowed this massive dataset and defined both OSA diagnosis and Parkinson's disease progression.

Critical methodological details emerge: How was OSA diagnosed—through sleep testing, and using 4% or 3% hypopnea criteria? How did the study differentiate between mild and severe sleep apnea? How was Parkinson's disease identified—through clinical notes, medication records, or longitudinal follow-up? Dr. Neilson clarifies whether the analysis included only PD or extended to other neurodegenerative disorders like Alzheimer's disease.

The core findings receive extensive examination: Did CPAP therapy have a modifying effect on PD risk? After adjusting for confounding factors including BMI, diabetes, depression, and hypersomnia, which variables mattered most? What was the number needed to treat to prevent one case of Parkinson's disease? Could hypoxic burden be examined as a potential mechanism?

Intriguing tangential discussions explore whether idiopathic RBD can be distinguished from trauma-related RBD and whether these represent separate pathological processes. The conversation takes an unexpected turn into the neuroprotective effects of smoking in Parkinson's disease, with Dr. Neilson explaining proposed mechanisms and drawing parallels to ischemic preconditioning that might occur with OSA.

The episode addresses severity gradients—did OSA severity correlate with PD risk? It also tackles a fundamental question: Does treating sleep apnea delay dementia onset or actually prevent it? Dr. Neilson discusses whether non-PAP therapies were examined and addresses a critical ethical concern in sleep apnea research: Is it irresponsible to withhold treatment from symptomatic patients, and did this study focus on non-sleepy individuals or include all OSA patients regardless of symptoms?

This research has profound implications for how sleep medicine practitioners frame the importance of OSA treatment with patients and families. Beyond addressing immediate symptoms like sleepiness, treating sleep apnea may reduce long-term neurodegenerative risk—a compelling motivation for adherence that extends beyond quality of life to disease prevention.

Whether you're counseling patients about the importance of OSA treatment, interested in the sleep-neurodegeneration connection, or seeking evidence-based approaches to discussing long-term benefits of therapy, this episode provides essential insights.

Community PAP Therapy: Engineering Better Sleep Apnea Care

In this episode of Talking Sleep, host Dr. Seema Khosla welcomes David Messerschmitt, a retired computer and signal processing engineer, and Stuart Crisp, a retired process control engineer and educator, to discuss patient-facing open-source PAP platforms and how informed users leverage detailed data to optimize their sleep apnea treatment.

This episode represents a departure from the typical clinical expert format. After eight seasons focusing on sleep medicine professionals, these engineer-patients reached out to share how platforms like Sleep HQ and OSCAR have transformed their understanding and management of sleep-disordered breathing. Both are power users who have helped thousands of fellow patients navigate complex PAP data, representing a patient empowerment movement that many clinicians may not fully appreciate.

David and Stuart explain what Sleep HQ and OSCAR are, how these platforms differ from standard clinical downloads, and what data visualization capabilities they offer. The platforms integrate multiple data streams—high-resolution flow rate data from PAP device SD cards, pulse oximetry from wearable rings, and sleep architecture from devices like Apple Watch—creating a comprehensive picture that goes far beyond what's typically reviewed in clinic appointments.

The conversation explores sophisticated analysis techniques these informed patients employ: identifying upper airway resistance syndrome through inspiratory flow limitation and heart rate spikes, distinguishing sleep onset versus wake onset events, detecting REM-related apneas, and recognizing positional apnea patterns. Stuart and David discuss "Somnopose," chin tuck events, and what they call "high-level waveform forensics"—detailed signal analysis that reveals subtle breathing pattern abnormalities.

A crucial discussion addresses whether these patient communities represent antagonism toward the medical establishment or an unmet need that sleep medicine should embrace. The guests emphasize their desire for collaboration, not confrontation, and offer insights into how clinicians can better partner with informed, data-driven patients who arrive with detailed self-analysis.

Whether you're encountering patients who bring detailed PAP data to appointments, curious about what these platforms reveal that standard reports don't, or seeking to better collaborate with informed patient communities, this episode provides essential perspectives from the patient side of sleep medicine.

Join us for this unique conversation that bridges the gap between clinical expertise and patient empowerment in sleep apnea management.

Comparing Hypoglossal Nerve Stimulators for OSA

In this episode of Talking Sleep, host Dr. Seema Khosla welcomes Dr. David Kent, Associate Professor and Director of Sleep Surgery in the Department of Otolaryngology-Head and Neck Surgery at Vanderbilt University Medical Center, to discuss the evolving landscape of hypoglossal nerve stimulation for obstructive sleep apnea treatment.

With the recent FDA clearance of a new hypoglossal nerve stimulator, patients now have three device options available or coming soon. Dr. Kent, whose research explores upper airway neurophysiology and novel OSA treatments, helps clinicians understand the fundamental differences between these devices and how to select the most appropriate option for individual patients. He discloses his past consulting relationship with Inspire and current consulting role with Nyxoah to provide transparent context for the discussion.

The conversation begins with the foundational premise of hypoglossal nerve stimulation and why it effectively treats obstructive sleep apnea. Dr. Kent traces Inspire's evolution since its 2013 FDA approval, explaining the current implantation process and how the technology has advanced over the past decade.

A significant focus is placed on Genio, with Dr. Kent explaining how its design resembles a cochlear implant—breaking down this comparison for pulmonologists and other non-surgical specialists. Critical distinctions emerge: Genio uses bilateral stimulation versus Inspire's unilateral approach, lacks a respiratory sensor, and employs an external rechargeable battery. Dr. Kent clarifies the practical implications of these differences, including how pulse delivery is timed without respiratory synchronization, what external battery charging means for daily use, smartphone Bluetooth connectivity, and MRI compatibility considerations.

The episode tackles important clinical questions: Is bilateral hypoglossal nerve stimulation superior to unilateral stimulation? Does complete concentric collapse (CCC) matter as a contraindication, and if conflicting data exists about CCC exclusion criteria, how should this inform patient selection? Is drug-induced sleep endoscopy (DISE) necessary for all candidates? Dr. Kent discusses how the STAR trial differed from the DREAM trial and how pandemic timing affected patient outcomes and data interpretation.

Looking toward the future, Dr. Kent provides insights into Aura6000, expected to be available in 2027, and discusses his research on ansa cervicalis stimulation as a potential complementary approach, acknowledging that hypoglossal nerve stimulation alone may not be the complete solution for all patients.

A particularly valuable discussion addresses setting realistic patient expectations. Dr. Kent shares his experience with patients who arrive with preconceived notions about Inspire based on marketing or word-of-mouth, requiring significant time to align expectations with reality. He walks through his clinical conversations comparing Inspire versus Genio, helping clinicians develop frameworks for these nuanced discussions.

Whether you're counseling patients about device-based OSA treatment options, trying to distinguish between available technologies, or preparing for the expanding landscape of hypoglossal nerve stimulation, this episode provides essential comparative insights.
