Poor Sleep Patterns Could Affect Your Health and Contribute to Obesity(1)

World Sleep Day - 19th March 2010

SLOUGH, England, March 19, 2010 - As a committed supporter of World Sleep Day, UCB has joined forces with
the World Association of Sleep Medicine (WASM) to raise awareness of the
importance of sleep for health, and to encourage those with sleep-affected
conditions to pay as much attention to the amount and quality of their sleep
as they do to their diet and exercise.

Up to a quarter of Britons have a clinical sleep disorder which can
include; insomnia, sleep apnoea and restless legs syndrome (RLS).(2) More
than 80% of those diagnosed with RLS have sudden uncontrolled limb movements
while they are asleep(3) - leading to disturbed sleep for them and their
partners.

"Sleep is vital to good health - just as much as cutting out processed
foods high in salt, sugar and fat." says Dr Adrian Williams, Founder of Sleep
Disorders Centre at St Thomas's Hospital, London. "For some conditions such
as Parkinson's disease and restless legs syndrome, symptoms have to be under
continuous control during sleep, so that disruption to morning activities and
exhaustion can be kept to a minimum."

Lifestyle and environmental factors are increasingly causing difficulties
sleeping, and sleep deprivation can result in physical repercussions,
cognitive impairment and mental health complications. These can include
fatigue, hypertension, performance and attention deterioration, diminished
concentration and intellectual capacity, and an increase in the likelihood of
accidents at work and while driving. (4)

"We are delighted to be supporting World Sleep Day this year - it is a
real opportunity to highlight the health benefits of a good night's sleep,"
said Rupert Haynes, Head of Movement and Sleep Disorders, UCB. "Many
conditions that are properly controlled at night can have a positive impact
on a person's quality of life."

About Restless Legs Syndrome(6)

Restless legs syndrome is a neurological disorder characterised by
unpleasant sensations in the legs and an uncontrollable urge to move when at
rest in an effort to relieve these feelings. RLS sensations are often
described by people as burning, creeping, tugging, or like insects crawling
inside the legs.
