Polysomnography in Centro de Neurología Avanzada (CNA)
About the clinic
Polysomnography at Centro de Neurología Avanzada (CNA) in Seville, Spain, is a detailed overnight sleep study used to identify neurological and respiratory sleep disorders. The clinic is a major reference center in Andalusia, performing over 350 videopolysomnographic studies every year. This diagnostic tracks brain activity, oxygen levels, and body movements in a controlled hospital environment to provide a complete picture of sleep health.
Study details and equipment
The examination takes place in a dedicated Sleep Unit equipped with three specialized monitoring beds. Patients stay overnight while a multidisciplinary team of neurologists, neurophysiologists, and neuropsychologists monitors their data. The study typically lasts between 6 and 8 hours. During this time, the equipment records several physical variables simultaneously.
- Brain electrical activity. Uses electroencephalography (EEG) to track sleep stages.
- Eye movements. Recorded via electrooculogram to identify REM sleep.
- Respiratory tracking. Measures oronasal airflow and oxygen saturation levels.
- Physical movements. Monitors thoracic and abdominal effort along with body position.
- Video recording. Synchronized video helps identify physical behaviors or seizures during sleep.
Diagnostic capabilities
The CNA Sleep Unit performs these tests at the Hospital Viamed Santa Ángela de la Cruz. The study helps specialists diagnose a wide range of conditions, including obstructive sleep apnea, narcolepsy, and restless legs syndrome. It is also used to differentiate between nightmares, parasomnias, and nocturnal epilepsy. While the study requires physical attendance at the clinic, patients may use video consultations to discuss their symptoms or review the final results with a doctor.
Centro de Neurología Avanzada holds Top Doctors recognition for private healthcare in Spain and operates across Seville, Huelva, Cádiz, Málaga, and Madrid. Patients interested in an overnight sleep study in Seville can request a consultation through Bookimed to arrange their diagnostic visit.

Centro de Neurología Avanzada (CNA): more details about the clinic
Centro de Neurología Avanzada (CNA) is a private neurology center in Sevilla, Spain. The clinic operates across multiple sites and provides multidisciplinary care for adults and children. Its medical team includes 20 doctors who specialize in neurology, neurosurgery, and psychiatry. The Sevilla facility has nine consultation rooms and four waiting areas.
Key Statistics and Recognitions
The clinic treats roughly 35,000 patients every year. Within the dedicated Sleep Unit, specialists perform over 350 videopolysomnographic studies annually. CNA holds Top Doctors recognition for its high standard of private healthcare in Spain.
Several physicians have earned individual professional awards:
- Dr. Hernando Pérez Díaz ranks among the 50 best doctors in Spain.
- Dra. Iratxe Maestro received research awards from the Sociedad Andaluza de Epilepsia.
- Dr. Pablo Clavel is recognized by Forbes as one of Spain's top 100 physicians.
CNA hosts epilepsy specialist rotations from Central America. The medical team also presents research at major events like the International Congress of Parkinson's Disease.
Neurological Care and Epilepsy Treatment
The clinic manages complex neurological conditions through specialized diagnostic and treatment pathways. The Epilepsy Unit uses prolonged video-EEG monitoring – up to 15 days – to identify seizure origins. This unit reports high surgical success rates:
- Over 85% of patients with lesion-based epilepsy become seizure-free.
- 84% of patients with mesial temporal sclerosis remain seizure-free after surgery.
- 79% of temporal lobe epilepsy patients achieve total seizure control.
For neurodegenerative diseases, CNA offers an integrated cognitive decline assessment pathway. The team uses blood biomarkers and PET amyloid imaging to diagnose early-stage Alzheimer's disease. Selected patients may receive advanced anti-amyloid therapies like Donanemab or Lecanemab.
Advanced Neurosurgery and Spine Care
The neurosurgery department focuses on vascular pathologies and tumor removal. Surgeons perform wide craniotomies to treat giant meningiomas measuring up to 8 cm. They use intraoperative neurophysiological mapping to protect brain function during these procedures.
The Spine Unit specializes in minimally invasive techniques for degenerative disc lesions. Dr. Pablo Clavel leads the Artificial Disc Replacement (ADR) program with 25 years of experience. The clinic has performed over 2,500 spine operations. More than 90% of patients report pain reduction.
Psychiatry and Pediatric Services
The Psychiatry department treats adult conditions including depression, anxiety, and personality disorders. Specialists use transcranial magnetic stimulation to treat medication-resistant depression. This non-invasive method uses magnetic pulses delivered through a coil on the head to adjust neural circuits.
Pediatric care comes from the Neurodevelopment and Learning Disorders Unit. The team includes neuropediatricians, psychologists, and speech therapists who treat emotional and behavioral disorders. This unit integrates family and school settings into each child's treatment plan.
Diagnostic Technologies
CNA provides a full range of neurological testing tools. Specialists use high-resolution Doppler sonography to assess vascular risks in stroke patients. The facility also offers electromyography (EMG) and visual evoked potentials to test nerve and brain function.
The Sleep Unit features specialized equipment for sleep disorder check-ups. Spine surgeons use microsurgical vision systems and radioscopic guidance for precise implant placement. For complex epilepsy cases, the clinic uses Sentiva devices for vagus nerve stimulation.
International Patient Services
International patients can access videoconsultations to review medical results and plan treatment. These online sessions allow initial assessments without travel. Physical attendance is only needed for imaging or instrumental studies. CNA partners with Hospital Universitario San Rafael for specialized care needs.
