A young woman describes having had a benign tumor. Since cancer runs in her family, she had a hysterectomy. As follow-up, her gynecologist treated her with hormonal replacement, until the patient learned that hormonal treatment may cause cancer similar to the cancer her mother experienced. Three months ago, she stopped taking the hormones and afterwards developed clinical depression. She reports depressive and anxiety symptoms, believing those symptoms are related to her sleep difficulty. She has tried over-the-counter sleep medications, but is seeking something stronger.

(National Institute of Neurological Disorders and Stroke) Hypersomnia refers to medical conditions in which you repeatedly feel excessively tired during the day (called excessive daytime sleepiness) or sleep longer than usual at night. It is different from feeling tired due to lack of or interrupted sleep at night. If you have hypersomnia, you might fall asleep repeatedly during the day, often at inappropriate times such as at work or during a meal. These daytime naps usually provide no relief from symptoms.

(MedlinePlus) Insomnia is a common sleep disorder. If you have it, you may have trouble falling asleep, staying asleep, or both. As a result, you may get too little sleep or have poor-quality sleep. You may not feel refreshed when you wake up.

(National Institute of Neurological Disorders and Stroke) Narcolepsy is a chronic neurological disorder that affects the brain's ability to control sleep-wake cycles. People with narcolepsy may feel rested after waking, but then feel very sleepy throughout much of the day. Many individuals with narcolepsy also experience uneven and interrupted sleep that can involve waking up frequently during the night.

(MedlinePlus) Narcolepsy is a nervous system problem that causes extreme sleepiness and attacks of daytime sleep.

(MedlinePlus) Narcolepsy is a chronic sleep disorder that disrupts the normal sleep-wake cycle. Although this condition can appear at any age, it most often begins in adolescence.

(Stanford Medicine) Sleep disorders involving abnormal behaviors during sleep are called parasomnias. These nighttime activities can occur at any age.

(MedlinePlus) Obstructive sleep apnea (OSA) is a problem in which your breathing pauses during sleep. This occurs because of narrowed or blocked airways.

(Johns Hopkins Medicine) Parasomnia disorders involve some type of abnormal behavior during sleep, such as walking or talking. Parasomnias may be categorized as primary parasomnias (disorders of sleep states) or secondary parasomnias (disorders of other organ systems that may manifest during sleep, including seizures, respiratory dyskinesia and gastroesophageal reflux).

(American Academy of Sleep Medicine) There are a variety of sleep disorders. Some are common, like insomnia, while others are rare. About 70 million people experience sleep disorders each year.

(MedlinePlus) Sleep disorders are conditions that disturb your normal sleep patterns. There are more than 80 different sleep disorders.

(National Heart, Lung, and Blood Institute) Circadian rhythm disorders, also known as sleep-wake cycle disorders, are problems that occur when your body’s internal clock, which tells you when it’s time to sleep or wake, is out of sync with your environment.

(American Psychiatric Association) Sleep disorders (or sleep-wake disorders) involve problems with the quality, timing, and amount of sleep, which result in daytime distress and impairment in functioning. Sleep-wake disorders often occur along with medical conditions or other mental health conditions, such as depression, anxiety, or cognitive disorders.
