Advanced Sleep Medicine for Complex Problems

Sleep problems often involve more than a single diagnosis. Breathing, circadian biology, medications, neurologic function, medical illness, behavior, and psychological factors can all influence sleep and daytime function.

Dr. Gharagozlou brings more than 25 years of medical experience to the evaluation of these interactions, with particular expertise in difficult cases, incomplete treatment response, and sleep disorders complicated by other medical or psychosocial conditions.

Scientific & Clinical Foundation

Before specialty training in sleep medicine, Dr. Gharagozlou completed postdoctoral research in neuropharmacology at VA Palo Alto and the Molecular Research Institute under world-renowned mentors like Jelveh Lameh, David Clark, and Stephen Shafer, producing multiple peer-reviewed publications, including NIH-supported research.

He subsequently completed advanced training in sleep disorders at the New Jersey Neuroscience Institute under Dr. Sudhansu Chokroverty and Dr. Arthur Walters, internationally recognized authorities in neurologic sleep medicine and sleep-related movement disorders.

His dual background in Internal Medicine and Sleep Medicine provides a broader clinical perspective when sleep symptoms interact with cardiometabolic disease, medications, neurologic conditions, psychiatric treatment, weight, or other medical problems.

Areas of Expertise

Healthy Sleep Care provides comprehensive sleep evaluation with particular experience in:

• Difficult or unsuccessful PAP therapy

• Obstructive, central, and complex sleep apnea

• Persistent sleepiness despite treated sleep apnea

• Narcolepsy and other hypersomnolence disorders

• Chronic and treatment-resistant insomnia

• Circadian rhythm and shift-work disorders

• Parasomnias and unusual nocturnal behaviors

• Restless legs syndrome and sleep-related movement disorders

• Complex fatigue involving multiple medical or psychosocial factors

• Second opinions when diagnosis or treatment remains uncertain

Connected Sleep Care

Modern sleep medicine extends beyond a single office visit or sleep study.

For appropriate patients, we integrate clinical follow-up with sleep-study findings, PAP device data, symptoms, medications, and longitudinal monitoring. This allows us to identify why treatment is working—or why it is not—and refine management over time.

Measure → Interpret → Treat → Monitor → Refine

Technology provides additional information. Specialist judgment determines what that information means for the individual patient.

Sleep, Circadian Health & Workforce Fatigue

The same sleep and circadian physiology that affects individual patients also influences alertness, performance, safety, and decision-making across organizations.

Healthy Sleep Care provides physician-led expertise for organizations confronting:

• Shift work and overnight operations

• Inadequate sleep opportunity and recovery time

• Fatigue-related performance and safety risk

• Circadian disruption from scheduling

• Executive and international travel demands

• Workforce education in sleep, alertness, and fatigue recognition

Our organizational work focuses on translating sleep and circadian science into practical approaches to scheduling, rest, fatigue-risk awareness, and human performance.
