Sleep Disorder Tests: Diagnosing Insomnia, Hypersomnia & More

Understanding Insomnia and Hypersomnia

Insomnia and hypersomnia are two opposite but equally disruptive sleep disorders. While insomnia means struggling to fall or stay asleep, hypersomnia involves excessive sleepiness during the day despite long hours of rest.

Recognising these symptoms early can help you seek the right support and understand what your body truly needs.

Understanding Different Types of Sleep Disorders

Insomnia and hypersomnia are two of the most recognised types of sleep disorders. While one involves difficulty falling or staying asleep, the other is marked by excessive sleepiness. Understanding the difference between sleep disorders like these sets the foundation for accurate diagnosis and treatment.

The Importance Of Accurate Diagnosis

Sleep disorders can occur as a standalone condition or as a result of other conditions or even coexist with other conditions like depression, anxiety, etc.

For this reason, it is important to get an accurate diagnosis of the condition. Accurate diagnosis also helps healthcare professionals to customize treatment plans based on individual needs.

Common Types Of Sleep Disorders

As mentioned earlier, there are different types of sleep disorders with their own set of symptoms and characteristics. Some types of sleep disorders are rare while some are more common than others.

So, let’s discuss in brief some of the common types of sleep disorders.

Chronic Insomnia

It is the most common type of sleep disorder, and some estimates suggest nearly every 1 in 3 adults suffer from insomnia. It is a type of condition that makes it difficult for you to fall asleep or stay asleep and consequently, you often feel tired, irritated, and have difficulty concentrating.

The condition can also increase the risk of developing serious health conditions like cardiovascular disease or impaired immune systems.

Obstructive Sleep Apnea

Sleep apnea is a condition that causes difficulty in breathing while you sleep. The lack of oxygen makes you wake up in between your sleep and interrupting your sleep cycle.

When you sleep, the muscles in your throat relax, which can narrow or block your airway and disrupt your breathing. This disruption in breathing is a major sign of sleep apnea.

Restless Legs Syndrome

Restless Leg Syndrome or RLS, is a condition that causes an extreme urge in one to move their legs. This condition especially happens during the evening when one is resting.

The exact cause of this sensation is not known; however, it forces you to move your legs to get relief from the sensation. This sensation can be tingling, burning, or itching which can greatly disturb your sleep.

Narcolepsy

Narcolepsy is a condition that affects your ability to sleep or wake. In our normal sleep cycle, we pass through different stages of sleep which finally culminate in rapid eye movement (REM).

However, people with this condition may directly enter the REM stage causing them to fall asleep suddenly and it is characterized by uncontrollable daytime sleepiness.

Blood Tests For Insomnia: What You Need To Know

Blood tests are quite safe and non-invasive ways your healthcare provider can check and get a variety of information about your health. The method can help in revealing iron levels, thyroid functions, hormone levels, mental health conditions, etc.

It can also help doctors to identify if other conditions are contributing to insomnia and based on the results, doctors prepare a customized treatment plan.

When Are Blood Tests Necessary?

You have probably visited many doctors and it is also possible that they may have recommended you a blood test. But why do doctors recommend blood tests and why it is necessary? Let’s understand.

A Blood test is one of the common ways for doctors to examine proteins, cells, chemicals, etc. in your blood and it can also help them diagnose certain conditions and diseases.

What Can Blood Tests Reveal About Your Sleep?

As mentioned in the above section, a blood test is a very effective way to reveal what exactly is going on in your body. It should not come as a surprise knowing that blood tests can also indicate your sleep quality.

Blood tests can reveal hormonal imbalances (like cortisol and melatonin), inflammation markers, and blood sugar levels, all of which can impact sleep quality.

7 Diagnostic Tests For Sleep Disorders

Now let’s talk about the other main topic of our discussion which is diagnostic tests for sleep disorders. Many tests can diagnose sleep problems, but here are some of the most common tests used for sleep disorders.

Polysomnography (Sleep Study)

Polysomnography, also known as a sleep study, is a diagnosis method that records the oxygen level in your blood, the brain waves, your heart rate, and your breathing while you sleep.

It is usually done at night in sleep labs where doctors record your vitals which also include muscle activity and eye movement.

Multiple Sleep Latency Test (MSLT)

MSLT is a method that helps doctors check excessive daytime sleeping and it is usually done after a sleep study. This test allows you multiple chances to take a nap throughout the day, generally consisting of 4-5 sessions of naps every two hours.

In this test, you are provided with a comfortable environment to fall asleep and once the lights are off the monitor will start measuring how much time it takes you to fall asleep.

Maintenance Of Wakefulness Test (MWT)

It is another diagnostic tool to measure daytime sleeping. It also measures how alert one is and one's ability to stay awake.

This tool not only measures daytime sleep duration but also assesses alertness and wakefulness. And like MSLT, in this test too, you are provided with multiple chances to sleep, with a two-hour gap.

Actigraphy

It is a non-invasive form of diagnosis where you need to wear a device that looks like a modern-day smartwatch, though the purpose here is much more different than the smartwatch.

The device monitors your movement throughout the day and night, tracking sleep data like sleep onset (falling asleep), wake episodes, sleep latency (time to fall asleep), and total wake time.

Home Sleep Apnea Testing (HSAT)

A home sleep apnea test (HSAT) is a convenient screening tool used primarily for obstructive sleep apnea.

It monitors breathing patterns, oxygen levels, snoring, heart rate, and body position during sleep. While not a proper diagnosis, HSAT can be a great tool in identifying potential sleep apnea.

Epworth Sleepiness Scale (ESS)

Epworth Sleepiness Scale is not a diagnosis, but a short self-assessment questionnaire used to assess your daytime sleepiness. In ESS, you go through a set of questions like how often you fall asleep while watching TV or being a passenger in a car.

Each question is rated on a scale of 0-3, the higher the scores, the greater the propensity to fall asleep during daytime.

Overnight Oximetry

It is one of the simplest diagnoses, in fact, it can also be performed at home. The test is used to monitor your heart rate and blood oxygen levels while you are sleeping.

It is often used as the first test for sleep disorders and doctors use it to understand your breathing pattern and to check if there is any dip in your oxygen level.

What to Expect During An Insomnia Test?

The insomnia diagnosis process typically involves several steps. First, your doctor will discuss your sleep patterns, including duration, quality, and any relevant lifestyle factors.

They may then recommend keeping a sleep diary for a week or two to track your sleep and wake times, along with nighttime awakenings. A physical exam may follow.

Finally, depending on the initial findings, additional tests like blood tests or a sleep study might be recommended.

Preparing For Your Sleep Disorder Test

Preparing for a sleep study depends on your doctor's advice and the type of test.

However, some general tips apply such as stick to your sleep schedule, avoid caffeine and alcohol for at least two days beforehand, skip naps on the test day, and eat a light, healthy dinner. During the test time, you will be taken to the sleep lab where the technician will attach the sensors to different parts of your body and measurements will be monitored by doctors and technicians from the other room.

How Doctors Diagnose Sleep Disorders

Diagnosing sleep disorders like insomnia and hypersomnia begins with a clinical evaluation. Doctors assess your sleep history, lifestyle, and medical background using tools like sleep diaries, questionnaires, and physical exams.

Understanding how to diagnose sleep disorders early can lead to better outcomes, helping to uncover patterns or conditions affecting your sleep quality.

What is an Insomnia Test?

There’s no single “insomnia test”. Doctors use multiple tools, including sleep diaries, symptom checklists, and questionnaires, all to track patterns over time.

This assessment, often referred to as an “insomnia test,” helps identify underlying issues like stress or circadian rhythm disruptions and guides treatment tailored to your sleep difficulties.

How is Hypersomnia Diagnosis Made?

Diagnosing hypersomnia involves careful evaluation through sleep history, physical exams, and tests like polysomnography or the Multiple Sleep Latency Test (MSLT).

This helps rule out conditions such as sleep apnoea or narcolepsy. Using the term “hypersomnia diagnosis” is key when describing this structured, evidence-based approach.

What is a Sleep Study Test (Polysomnography)?

A sleep study test, or polysomnography (PSG), monitors your brain and body during sleep. It records brain waves (EEG), eye movements (EOG), muscle activity (EMG), and breathing.

PSG is essential to detect conditions like sleep apnoea, restless legs syndrome, and narcolepsy, helping doctors recommend the right treatment.

Common Types of Sleep Disorder Assessments

Each assessment offers unique insights, understanding their purpose helps guide accurate diagnosis and effective treatment.

• PSG: Full overnight sleep study
• MSLT: Measures daytime sleepiness
• MWT: Assesses ability to stay awake
• Actigraphy: Tracks movement patterns
• HSAT: Home sleep study
• Sleep Diaries & Questionnaires: Capture everyday sleep behaviours and symptoms for accurate analysis

When to Consult a Sleep Specialist

If poor sleep disrupts your daily life or causes extreme fatigue, it may be time to see a sleep specialist.

They can offer advanced tests and personalised treatment plans. Sleep clinics play a vital role in diagnosing conditions like insomnia and hypersomnia, don’t hesitate to reach out for help.

After The Diagnosis: Next Steps

After the diagnosis has been completed, depending on whether it was done in a lab or at home, the information and data will be reviewed by the doctor, and this may take some time to convert into results.

Treatment Options Based On Test Results

A follow-up appointment will be scheduled by your doctor and during this appointment, based on the results and findings, the doctor will recommend or prescribe certain treatment options.

Lifestyle Changes And Management Strategies

Our lifestyles often lead to certain health conditions, including sleep disorders. Thus, it is likely that the doctor may recommend you adopt certain healthy lifestyles, such as a balanced diet, regular exercise, good sleep hygiene, and stress management techniques like yoga, mindful meditations, etc.

Exploring Insomnia Treatment Approaches

Managing insomnia often starts with identifying triggers and adjusting routines. Treatments include Cognitive Behavioural Therapy for Insomnia (CBT-I), sleep hygiene improvements, short-term medication, and structured lifestyle changes that support long-term sleep regulation.

Cognitive Behavioural Therapy (CBT-I)

CBT-I is a structured, evidence-based therapy that helps people change negative thought patterns and behaviours around sleep. It’s often the first-line treatment for chronic insomnia and focuses on building healthier associations with sleep.

Lifestyle & Sleep Hygiene Changes

Small, consistent lifestyle changes can significantly improve sleep quality. Some of the positive changes include: -

• Stick to a fixed sleep schedule
• Reduce exposure to screens and blue light before bed
• Maintain a quiet, cool, and dark sleep environment
• Develop a relaxing bedtime routine

Treatment Options for Hypersomnia

Treating hypersomnia usually begins with a detailed sleep assessment, often involving a sleep study to rule out narcolepsy or other conditions. Treatment options include:

• Medication, prescribed with caution
• Structuring daily routines to regulate energy levels
• Addressing underlying health or mental health conditions
• Following good sleep hygiene practices

Key Differences: A Sleep Disorder Comparison

Insomnia and hypersomnia differ in cause, symptoms, and daytime impact. Insomnia is linked to insufficient or disrupted sleep, while hypersomnia involves sleeping too much and still feeling unrefreshed. Understanding this sleep disorder comparison is key to early recognition and treatment.

Diagnosis: How Are These Disorders Identified?

Diagnosis for both insomnia and hypersomnia begins with a clinical evaluation and may include tools like sleep diaries and polysomnography (overnight sleep study). For hypersomnia, assessing excessive daytime sleepiness is critical to differentiate it from other sleep issues.

Impact on Daily Life & Mental Health

Sleep disorders like insomnia and hypersomnia affect more than just rest; they interfere with how the brain and body function throughout the day. Poor sleep disrupts mood regulation, lowers cognitive performance, and drains overall energy levels. Over time, this can contribute to serious mental health issues such as anxiety and depression. Whether it’s struggling with focus or battling daytime fatigue, the ripple effects of disordered sleep often go unnoticed until they become chronic.

Improving Sleep Quality: General Tips

Improving sleep doesn’t always require medication; often, it starts with small behavioural changes. Focus on building a calming bedtime routine, maintaining a consistent sleep schedule, and optimising your sleep environment for comfort and quiet.



Good sleep hygiene also includes avoiding screens before bed, limiting caffeine intake, and taking time to wind down before sleeping. These universal tips can benefit anyone, whether you’re struggling with insomnia, hypersomnia, or simply inconsistent rest.
