Sleep disorders

Sleep disorders: overview

Sleep disorders are a group of conditions that affect the ability to sleep well and feel rested. These disorders can range from difficulty falling or staying asleep to excessive daytime sleepiness, and can have significant impacts on quality of life, physical and mental health, and daily functioning. The National Institutes of Health (NIH) estimates that up to 70 million Americans have a sleep disorder, with millions more undiagnosed and untreated.

Types of Sleep Disorders

# Insomnia: Insomnia is a common sleep disorder that involves difficulty falling or staying asleep, and waking up feeling unrefreshed. Chronic insomnia (lasting at least three nights a week for a month or longer) can lead to feelings of anxiety and depression, as well as physical symptoms like fatigue, headaches, and muscle aches.

# Sleep apnea: Sleep apnea is a serious sleep disorder characterized by repeated pauses in breathing during sleep, which can last from a few seconds to a minute or more. These pauses can occur hundreds of times a night and lead to fragmented, non-restorative sleep, and excessive daytime sleepiness. Sleep apnea is often associated with obesity, high blood pressure, and other medical conditions.

# Narcolepsy: Narcolepsy is a neurological sleep disorder characterized by excessive daytime sleepiness and sudden, irresistible episodes of sleep, known as “sleep attacks.” People with narcolepsy may also experience vivid dream-like hallucinations before falling asleep or upon waking, and sleep paralysis, where they are unable to move or speak when falling asleep or waking up.

# Restless leg syndrome (RLS): RLS is a sleep disorder characterized by uncomfortable sensations in the legs, such as tingling, crawling, or aching, which are relieved by movement. These sensations usually occur in the evening or at night and can make it difficult to fall asleep or stay asleep.

# Sleepwalking: Sleepwalking, also known as somnambulism, is a sleep disorder characterized by walking, talking, or performing other activities while asleep. Sleepwalking usually occurs during the deep stages of sleep, and the person is not fully aware of their actions.

Why this matters for local patients

• Sleep symptoms such as snoring, witnessed pauses in breathing, daytime sleepiness, fatigue, insomnia and restless sleep can affect work, driving, mood, metabolism and long-term health.
• Many patients in NYC, New Jersey, Connecticut and Philadelphia prefer convenient evaluation, home sleep study options and fast follow-up rather than waiting months for care.
• W8MD combines sleep medicine with obesity medicine, helping patients address both breathing during sleep and weight-related metabolic risk.
