Sleep disorders can affect your ability to fall asleep, breathe comfortably at night or stay alert during the day. Recognising a pattern helps you describe the problem, but symptoms alone are not a diagnosis.
Insomnia and sleep apnea
Insomnia involves difficulty sleeping despite having an opportunity to sleep, with effects on daytime functioning. Sleep apnea causes repeated breathing interruptions during sleep. Both may leave you feeling unrefreshed, but their assessment and treatment differ.
Restless legs syndrome
Restless legs syndrome causes an urge to move the legs, often with uncomfortable sensations. Symptoms typically become more noticeable at rest in the evening or night and may ease temporarily with movement. It can make settling to sleep difficult. A clinician can assess possible contributing factors and suitable treatment.
Narcolepsy
Narcolepsy is a neurological condition that can cause excessive daytime sleepiness and sudden sleep episodes. Some people also experience brief muscle weakness triggered by emotions. These symptoms need specialist assessment; ordinary tiredness does not automatically mean narcolepsy.
When should you get help?
- Sleep difficulties repeatedly affect work, mood or concentration.
- You frequently fall asleep unintentionally.
- A partner notices breathing pauses or gasping.
- Leg discomfort regularly interrupts rest.
Bring a symptom timeline and medication list to your appointment. Testing is chosen according to the suspected condition, rather than using the same test for everyone.
Frequently asked question
Can more than one sleep disorder occur together?
Yes. For example, someone can have insomnia symptoms alongside sleep apnea. Your clinician considers the whole pattern before recommending care.
