What is Sleep Study?

The sleep study consists of a non-invasive test called a polysomnogram. This records a variety of body functions during sleep such as electrical activity of the brain, sleep pattern, breathing, oxygen levels, heart rate and rhythm, and muscle tone. The sleep technologist will connect the patient to the monitoring equipment via a series of stick-on electrode patches. The wires are long enough so that you can sleep in any position you wish. Once the study is complete, the test data is reviewed and "scored" by a specialist and relevant recommendations are made.

LEVELS OF SLEEP STUDY

Complete Study--

  • Level 1 :

(Clinic) In this, the patient is asked to come to the clinic in night's comfortable clothing at 9:30 pm on the day of the test - a sleep technologist will place sensors on patient's scalp, face, chest and legs. These sensors will record brainwave activity (to assess sleep stage), eye movements, muscle activity, heart rhythm, body movements, nasal/oral airflow, respiratory effort and oxygenation. The test is an overnight test, will continue till the usual wake-up time of the patient.

  • Level 2 :

(Home-based) It's the same study like clinic- based, the only difference is it is performed at patient's home and the technician will stay overnight at patient's home till the completion of the test.

CPAP Titration-will be performed during the above if required on the same night.

Screening-(without technician)

  • Level 3 :

In this the Technician will go to the patients home and fix the machine, will teach the patient how to use the equipment but NOT spend the night. The equipment shall be picked up the next morning or dropped by patient(after discussion). This will record more than 4 channels i.e. snoring, breathing effort, oxygen saturation and ECG.

How can I get a sleep study done?

You need to make an appointment for the study. The test is conducted at night. It is advisable to meet with a sleep specialist before the test,

What's involved in a sleep study? :

  • The patient comes to the hospital at 8:30 - 9:00 pm at night of the study and leaves the following morning when the study is complete, at about 5:30 - 6:00 am.
  • On the day of your sleep study, avoid caffeine (coffee, tea, cola, chocolate) after 2.00 pm and try not to nap.
  • Before coming to sleep centre, wash and dry your hair, and not apply hair sprays or oil.
  • After you arrive at the sleep center, you may be asked to complete a questionnaire on your symptoms and asked to change into your night clothes. The technician will connect you to a few sensors that will record your brain waves, eye movements, and muscle movements throughout the night. A microphone attached to your neck records snoring, and two belt-like straps around the chest and lower abdomen monitor muscle movement during breathing.
  • When everything is working properly, the lights will be turned off and you can go to sleep. You will be awakened in the morning and the electrodes will be removed. Since they are applied with water-soluble glue or tape, removal isn't painful

More about sleep study

If you can’t decide which sleep study is right for you we can help -please call us on 011-46070321, 011-41656260,9643500270 on Monday-Saturday from 10 to 5 pm.

Choosing a wrong sleep study will lead to:

  • 1. misdiagnosis, underdiagnosis,
  • 2. Delay in treatment.

When will I know the result? :

Usually after 48 hours-72 hours.

Important: :

If your symptoms change significantly (either better or worse) or if you are unwell just prior to your allocated night in sleep laboratory, please notify us immediately.

Continuous Positive Airway Pressure(C.P.A.P.)

Treatment for sleep apnoea (stopping breathing during sleep) involves the use of a nasal CPAP (Continuous Positive Airway Pressure) machine.

The set-up for the CPAP trial involves all the same leads as the diagnostic study. The technicians will increase the pressure of the machine until the person stops snoring and they are breathing without obstruction. Airway splinted open air flows freely to lungs. Know More

Multiple Sleep Latency Test (MSLT)

  • This test is conducted during the day and usually follows immediately after a routine study. You get up at your usual time but no later than 7:30 am, get dressed and have breakfast.
  • At around 9 or 9:30 am you lie down in a quiet dark room for twenty minutes to see whether or not you fall asleep.
  • After twenty minutes you get up you read or do some work until the next nap which is around 11:00- 11:30 am.
  • There are at least four naps finishing at around 3:30pm.
  • During the test you are not allowed to have any caffeine as this will affect your sleep. This means no coffee, tea or Chocolates!

Restless Legs Syndrome (RLS):

Restless Legs Syndrome (RLS), also known as Willis-Ekbom Disease, is a neurological disorder that causes an uncontrollable urge to move the legs, typically accompanied by uncomfortable sensations. These symptoms mainly occur at rest, in the evening or night, leading to significant sleep disturbances.

1. Symptoms of RLS:

The primary symptoms include:

  • Unpleasant sensations in the legs – Described as crawling, tingling, itching, aching, pulling, or throbbing.
  • Irresistible urge to move the legs – Provides temporary relief from discomfort.
  • Symptoms worsen at night – Making it difficult to fall or stay asleep.
  • Symptoms triggered by rest/inactivity – Such as sitting for long periods or lying in bed.
  • Periodic Limb Movements in Sleep (PLMS) – Involuntary jerking movements that can further disrupt sleep.

2. Causes & Risk Factors:

RLS can be primary (idiopathic) or secondary to underlying conditions.

    Primary RLS:
  • Often genetic (family history common).
  • No identifiable cause.
    • Secondary RLS:
  • Iron deficiency (low serum ferritin).
  • Pregnancy (especially in the third trimester).
  • Chronic kidney disease.
  • Neurological disorders (e.g., Parkinson’s, multiple sclerosis).
  • Diabetes & Peripheral neuropathy.
  • Excess caffeine, alcohol, nicotine.

3. Diagnosis of RLS:

RLS is primarily a clinical diagnosis based on the following:

Diagnostic Criteria (International RLS Study Group - IRLSSG):
  • Urge to move the legs, usually with unpleasant sensations.
  • Symptoms worsen at night or in the evening.
  • Symptoms triggered by rest/inactivity.
  • Movement provides temporary relief.
  • No other medical conditions explain the symptoms.

Supporting Tests:

  • Iron studies: Serum ferritin <50 ng/mL may indicate iron deficiency.
  • Neuropathy tests: If associated peripheral neuropathy is suspected.
  • Sleep Study (Polysomnography, PSG): If periodic limb movements in sleep (PLMS) are suspected.

    • 4. Role of Sleep Study (Polysomnography) in RLS:

    • Not required for RLS diagnosis but helps assess sleep disruption due to PLMS.
    • Identifies Periodic Limb Movements in Sleep (PLMS) – Repetitive leg jerks occurring every 20-40 seconds during sleep.
    • Confirms RLS-related sleep fragmentation, which may lead to excessive daytime sleepiness (EDS).
    • Differentiates RLS from other sleep disorders like sleep apnea.

    5. Treatment & Management:

    A. Lifestyle & Non-Pharmacological Approaches
    • Regular Exercise – Moderate activity (not too intense).
    • Sleep Hygiene – Maintaining a consistent sleep schedule.
    • Avoid Triggers – Reduce caffeine, alcohol, nicotine.
    • Leg Massage & Warm Baths – May help alleviate symptoms.
    • Iron Supplementation – If ferritin levels are low (<50 ng/mL).
    B. Medications (for Moderate to Severe RLS)
    • Dopamine Agonists -Pramipexole, Ropinirole (first-line treatment).
    • Alpha-2-Delta Ligands -Gabapentin, Pregabalin (especially if pain or neuropathy is present).
    • Low-dose Opioids -(for severe cases unresponsive to other treatments).
    • Benzodiazepines –(Clonazepam) – May help improve sleep but not first-line.
    6. Conclusion

    RLS significantly impacts sleep quality and daily functioning. Early diagnosis and proper management—especially identifying iron deficiency and periodic limb movements in sleep (PLMS) through a sleep study—can greatly improve symptoms.
