Medical Specialty: Sleep Medicine

Sleep medicine is a medical specialty or subspecialty devoted to the diagnosis and therapy of sleep disturbances and disorders. From the middle of the 20th century, research has provided increasing knowledge and answered many questions about sleep-wake functioning.

Sleep Medicine
CPAP Titration Study
The patient was monitored for EEG, EOG, jaw and leg EMG, thoracoabdominal impedance, oral/nasal thermistors, EKG, and oximetry.
Normal awake and drowsy (stage I sleep) EEG for patient's age.
Electroencephalogram - 1
Electroencephalogram (EEG). Photic stimulation reveals no important changes. Essentially normal.
Electroencephalogram - 2
Electroencephalogram (EEG). This is an 18-channel recording obtained using the standard scalp and referential electrodes observing the 10/20 international system.
Electroencephalogram - 3
Abnormal electroencephalogram revealing generalized poorly organized slowing, with more prominent slowing noted at the right compared to the left hemisphere head regions and rare sharp wave activity noted bilaterally, somewhat more prevalent on the right.
Electroencephalogram - 4
A 21-channel digital electroencephalogram was performed on a patient in the awake state.
Electroencephalographic findings and interpretation
Obesity Hypoventilation Syndrome
Obesity hypoventilation syndrome. A 61-year-old woman with a history of polyarteritis nodosa, mononeuritis multiplex involving the lower extremities, and severe sleep apnea returns in followup following an overnight sleep study.
Overnight Polysomnogram
The patient underwent an overnight polysomnogram.
The patient was monitored for EEG, EOG, jaw and leg EMG, thoracoabdominal impedance, oral/nasal thermistors, EKG, and oximetry. The test was performed due to suspicion of sleep apnea and poor sleep quality with frequent awakenings.
Pulmonary Consultation - 1
Obstructive sleep apnea syndrome. Loud snoring. Schedule an overnight sleep study.
Sleep Apnea
Followup of moderate-to-severe sleep apnea. The patient returns today to review his response to CPAP. Recommended a fiberoptic ENT exam to exclude adenoidal tissue that may be contributing to obstruction.
Sleep Difficulties
Electroencephalogram, electromyogram of the chin and lower extremities, electrooculogram, electrocardiogram, air flow from the nose and mouth, respiratory effort at the chest and abdomen, and finger oximetry.
Sleep Study Followup
Followup after a full-night sleep study performed to evaluate her for daytime fatigue and insomnia. This patient presents with history of sleep disruption and daytime sleepiness with fatigue. Her symptoms are multifactorial.
Sleep Study Interpretation
Sleep study - patient with symptoms of obstructive sleep apnea with snoring.
Chronic snoring in children
Video EEG
This is a 43-year-old female with a history of events concerning for seizures. Video EEG monitoring is performed to capture events and/or identify etiology.
Video EEG - 1
The patient has a history of epilepsy and has also had non-epileptic events in the past. Video EEG monitoring is performed to assess whether it is epileptic seizures or non-epileptic events.
Video EEG - 2
EEG during wakefulness, drowsiness, and sleep with synchronous video monitoring demonstrated no evidence of focal or epileptogenic activity.
Video EEG - 3
EEG during wakefulness and light sleep is abnormal with independent, positive sharp wave activity seen in both frontotemporal head regions, more predominant in the right frontotemporal region.
