A New Model for
Comprehensive Sleep Care
In Budapest today, sleep medicine remains fragmented. Patients undergo diagnostic testing in one location, then must independently seek neurologists, pulmonologist, ENT specialists, dentists, cardiologists, psychologists, or other professionals—often without coordination, continuity, or a unified treatment strategy.
As a result, patients may not always have access to the most current,
evidence-based approaches to care.
The Sleep Institute has been precisely created to change all these.
The Sleep Institute-Istenhegyi: Global Expertise, Local Care
The Multidisciplinary Board:
A Unified Clinical Front at The Sleep Institute
A diagnosis is not the end of the journey—it is the beginning of a coordinated care plan.
Our medical specialists do not work in silos. Our internal structure at Istenhegyi allows for a "Sleep Board" review, where your case is discussed by a Neurologist, a Pulmonologist, an ENT Surgeon, and a Clinical Psychologist.
This ensures if your sleep apnea has a neurological component, or your insomnia is linked to a respiratory issue, both are treated simultaneously under one roof.
A Center of Excellence:
The Sleep Institute-Istenhegyi
While our science is international, our care is patient-centered. Located in the heart of Budapest's 12th district, our facility at Istenhegyi Klinika combines:
circle Serene Comfort: Private, sound-insulated diagnostic suites designed to mimic a high-end home environment to help you relax, creating the optimal environment for a restful night.
circle Medical Synergy: Immediate access to Istenhegyi's internal network of medical disciplines, such as cardiology, ENT surgery, and neurology, to ensure comprehensive care.
circle Advanced Diagnostics: The latest in high-density polysomnography and actigraphy technology - featuring cutting-edge, medical-grade monitoring systems that capture highly precise sleep data seamlessly and comfortably throughout the night.
The Madrid-Budapest Connection
Madrid - Instituto del Sueňo
Budapest - The Sleep Institute-Istenhegyi
Our Budapest flagship is a direct extension of the Sleep Research Institute (IIS) in Madrid.
Under the medical direction of Dr. García-Borreguero—a global authority in Restless Legs Syndrome (RLS) and circadian disorders—our protocols are built on decades of clinical trials and international leadership.
We bring a new level of neurological depth to Budapest that goes beyond simple sleep apnea testing.
A Message from the Medical Director:
Dr. Diego García-Borreguero
"Our mission at The Sleep Institute is to bridge the gap between cutting-edge research and daily clinical practice.
At our Istenhegyi location, we don’t just treat sleep apnea or insomnia; we look at the complex neurological and physiological architecture of your rest.
Every diagnosis made in Budapest follows the same rigorous multidisciplinary standards we have pioneered in Madrid and beyond."

The Patient Journey: Your Path to Restorative Sleep
Step 1: The Initial Expert Consultation
Your journey begins with an in-depth clinical evaluation by our sleep specialists. We look beyond basic fatigue to map your circadian rhythm, medical history, and neurological profile.
circle Pre-Screening: Digital sleep diaries and validated questionnaires to be completed before your visit.
circle Consultation: A 45-to-60-minute comprehensive clinical assessment at our Istenhegyi Klinika.
circle The Goal: Identifying whether your symptoms are respiratory, neurological, or behavioral
Step 2: Advanced Diagnostics (The Sleep Lab Experience)
If a sleep study is required, you will spend a night in our state-of-the-art laboratory at Istenhegyi Klinika.
circle Boutique Environment: Premium soundproofed suites with ensuite facilities ensuring natural sleep.
circle Gold-Standard Monitoring: High-density Polysomnography (PSG) tracking brain waves, oxygen levels, muscle activity and heart rate.
circle Professional Supervision: Overnight real-time tracking by technicians from a discrete central station.
Step 3: Integrated Results & Multidisciplinary Review
Within days of your study, your sleep data is analyzed using protocols established by world-renowned expert Dr. Diego García-Borreguero.
circle The Board Review: Complex cases are cross-examined by a multidisciplinary team of Neurologists, ENT surgeons, and Pulmonologists.
circle Comprehensive Report: A detailed breakdown mapping your exact sleep architecture rather than a simple pass-or-fail metric.
Step 4: Tailored Treatment & Long-Term Follow-up
A diagnosis is only the beginning. We create a personalized "Sleep Roadmap" matching your specific clinical profile.
circle Precision Titration: Dedicated CPAP "adaptation night" ensuring perfect mask fit and pressure settings.
circle CBT-I Programs: Evidenced-based cognitive behaviour therapy sessions tailored for chronic insomnia.
circle Specialized RLS Management: Advanced restless legs treatment utilizing the latest pharmacological and neuromodulation research from our Madrid center.
circle Ongoing Continuity Care: Scheduled 3, 6, and 12-month reviews tracking long-term treatment efficacy.
Patient Success Story - "Clinical Case Studies"
Case Study 1: The "Augmented" RLS Patient
Your journey begins with an in-depth clinical evaluation by our sleep specialists. We look beyond basic fatigue to map your circadian rhythm, medical history, and neurological profile.
The Patient: 55-year-old male, suffering from RLS for 10 years. Medication was no longer working (Augmentation).
The Intervention: 2 weeks targeted neuromodulation paired with Dr. García- Borreguero's iron-metabolism protocol.
The Result: 70% reduction in symptoms with “zero” medication increases. Patient reported the first "quiet legs" night in three years.
Case Study 2: The Treatment-Resistant Insomniac
Your journey begins with an in-depth clinical evaluation by our sleep specialists. We look beyond basic fatigue to map your circadian rhythm, medical history, and neurological profile.
The Patient: 42-year-old executive, dependent on sedatives but still experiencing highly fragmented sleep.
The Intervention: Multidisciplinary approach-6 sessions of Neuromodulation to “quiet” the hyperaroused cortex, paired with on-site CBT-I.
The Result: Patient successfully tapered off sedatives and restored a natural sleep onset under 20 minutes.

The Future of Sleep Medicine:
Non-Invasive, Drug-Free, Targeted Neural Care
Introducing Innovative Therapies: Magnetic Neuromodulation
At The Sleep Institute-Istenhegyi, we are proud to introduce Magnetic Neuromodulation (specifically rTMS and related protocols), a cutting-edge therapy brought directly to our facility through our clinical partnership with the Sleep Research Institute in Madrid.
This advanced technology allows us to safely target the neurological mechanism underlying sleep disruptions without the systemic side effects of traditional sedative medications.
How It Works: Precision for the Sleeping Brain
Magnetic Neuromodulation uses brief, focused magnetic pulses to gently modulate specific neural circuits involved in the sleep-wake cycle.
circle Targeted Action: Unlike oral medication, which affects the entire body, neuromodulation targets the specific area of the brain responsible for sleep regulation (the "internal clock") or the sensory-motor cortex.
circle Non-Invasive Comfort: There is no anesthesia, no surgery, and no downtime. Patients remain fully awake and relaxed during the 20 to 30-minute sessions.
circle Harnessing Neuroplasticity: By delivering repetitive pulses, the therapy aims to "retrain" the brain to return to its natural, healthy sleep architecture over a series of sessions.
Who Is It For?
Drawing from global clinical insights and the pioneering work on neural stimulation by Dr. Diego García-Borreguero, we offer this advanced modality for patients who have not found relief through standard therapies:
circle Refractory Restless Legs Syndrome (RLS): For patients whose symptoms have "augmented" or failed to respond to traditional dopaminergic medications.
circle Chronic Treatment-Resistant Insomnia: An alternative option for individuals who wish to break the cycle of dependency on sleep medications and restore natural sleep onset.
circle Circadian Rhythm Disorders: Helping the brain’s "Master Clock" reset itself for shift workers or those living with delayed sleep phase syndrome.
circle Comorbid Sleep & Mood Disorders: Highly effective for addressing cases where chronic sleep disruption is deeply intertwined with anxiety or depression.
