A good night’s sleep is essential for the

maintenance of physical, mental and

emotional wellbeing, with many sleep

conditions leading to a vastly reduced

quality of life.

London Bridge Hospital has recently set

up a dedicated Sleep Centre to provide

diagnostic observation and subsequent

treatment for those patients who may

be suffering from one or more of the

symptoms below:

• Anxiety about sleep

• Dryness of the throat

• Excessive daytime sleepiness

• Excessive fatigue

• Excessive snoring

• Impaired daytime mental alertness

• Inability to wake

• Insomnia

• Poor quality sleep

• Witnessed apnoea episodes


• Any nocturnal parasomnias, i.e. all

unwanted sleep behaviours, such as

sleepwalking, sleep talking, bruxism

(teeth grinding), bed-wetting etc.

Sleep disturbances can also encompass

a huge range of conditions such as:

• Narcolepsy

• Nasal/upper airways symptoms

• Nocturnal epilepsy/fits

• Obesity

• Obstructive Sleep Apnoea

• Parasomnias

• Snoring

The Sleep Centre works alongside Dr

Guy Leschziner who reviews patients’

results, helps diagnose a condition and

prescribes the most effective treatment

available. The tests that are undertaken

at the Sleep Centre include:


A full PSG is an overnight sleep study

which provides an extensive analysis of

sleep by charting a patient’s breathing,

heart rate, eye movements, leg

movements, muscle tension and brain

wave formations as the patient sleeps.

A full PSG is often used as a diagnostic

test to look for sleep-related breathing

disorders such as sleep apnoea. A

PSG can also pick up and observe

behaviours during sleep which could

ultimately be harmful for the patient or

those around them, for example violent

episodes or sleepwalking.



An MSLT can also be called a ‘nap

study’. This test is used to identify how

quickly the patient falls asleep in a

quiet daytime situation. A patient who

experiences excessive sleepiness would

be classed as a person who constantly

feels sleepy in situations in which you

should ‘normally’ be awake and alert.

An MSLT test is primarily used to

evaluate patients who are suspected to

have narcolepsy – most patients with

narcolepsy fall asleep in an average of

less than 5 minutes during the MSLT.


EEG (Electroencephalograph) is a

recording and monitoring of the

electrical activity in the brain over a

sustained period of time.

Video telemetry is used for:

• Diagnosing epilepsy (and the type of


• Epilepsy treatments and medications

• Diagnosing and differentiating


• Syncope events

• Medication adjustments



An Apnoea Link is a diagnostic tool

that records nasal pressure during

sleep which can be used to screen

for Obstructive Sleep Apnoea. The

patient would come into London Bridge

Hospital to have a short consultation

to explain how each component of the

link is fitted. The device is then taken

home by the patient and worn whilst

they are asleep. As the patient sleeps,

the Apnoea Link records three channels

of information:

• Oximetry

• Pulse

• Respiration




Following the diagnosis of a sleep

disorder such as Obstructive Sleep

Apnoea, CPAP is often the most

effective therapy for treating these

disorders. These systems work on

the principle of supplying positive air

pressure through a tube and mask in

order to hold open obstructed airways.

These devices are designed to provide

substantial symptomatic benefits to

patients by allowing a more restful and

uninterrupted sleep.


Traditionally, a CPAP Titration study

involves an overnight, in-clinic evaluation

of airway pressure requirements,

resulting in a precise pressure

prescription for your CPAP monitor.

We can offer a second type of CPAP

monitor that actually monitors airway

requirements as the patient sleeps

and automatically adjusts the pressure

settings throughout the night, according

to the individual’s needs. This effectively

eliminates the need for a formal

overnight assessment. These monitors

are referred to as APAP (Automatic

Positive Airway Pressure) monitors

and assessment or titration can be

performed over a two-week trial

period in the comfort of the patient’s

own home.
