Márta Novák, MD, PhD
    Associate Professor

The group focuses its research on the following areas: 1) Epidemiology of sleep disorders both in the general population and in patients with different chronic medical conditions; 2) Psycho-social and medical consequences of sleep disorders; 3) The role of restorative sleep in memory consolidation and daytime neurocognitive functioning.

We have determined the prevalence and correlates of specific sleep disorders in patients with chronic kidney disease. We have demonstrated increased cardiovascular morbidity and increased health care resource utilization by individuals with sleep problems. We have also reported the association of specific outcome measures (health related quality of life and mortality) both in cross-sectional datasets and in prospective cohort studies.

We utilize data from epidemiologic surveys, and also use standard questionnaires and standard polysomnography. We employ psychological testing and complex analysis of extended EEG recordings.

Currently we study the association of obstructive sleep apnoe (OSA) with measures of cardiovascular morbidity in patients with high cardiovascular risk. We also analyze the association of OSA with new onset cardiovascular morbidity and mortality. We also analyze the association of sleep problems with chronic inflammation to reveal potential factors in the pathomechanism of those disorders.

Finally, we currently investigate complex interrelationship between objectively measured sleep parameters, phasic and tonic sleep EEG activity, levels of subjective (Epworth Sleepiness Scale) and objective (Multiple sleep latency test) sleepiness and neurocognitive impairments.

Dr. Novák is an internationally recognized somnologist, psychiatrist. She has published 40 papers, 17 book chapters and edited the most comprehensive handbook on sleep medicine in Hungary. She has active collaborations both in Europe and in North America. Her cumulative impact factor is 59.42, with 63 independent citations.
