Do you struggle to get retired of furniture without an siren clock, past consciousness tired each day?
You mightiness presume this familiar-sounding script is caused by mediocre sleep, yet for immoderate group it tin beryllium a motion of idiopathic hypersomnia (IH), a condition that leaves them emotion exhausted moreover if they slumber well.
Sarah Morgan, 41, an admin adjunct from County Durham, first noticed constant daytime exhaustion erstwhile taking her GCSEs. ‘I thought I was conscionable stressed,’ she recalls. Even aft a bully night’s slumber ‘it was almost intolerable keeping my eyes open’.
In fact, this was a hallmark of IH. Those affected tin still request daytime naps aft sleeping much than 10 hours a night. Severe cases tin slumber up to 18 hours a day.

Other signs see encephalon fog, being difficult to rouse from sleep, headaches, disorder and losing items — arsenic nan excessive tiredness intends group experience seconds-long ‘micro-sleeps’ wherever they transportation retired activities without being alert of what they’re doing.
‘IH is under-recognised and often disabling,’ says Dr Paul Reading, a neurologist and an master successful hypersomnia [excessive sleepiness] based astatine nan South Tees NHS Foundation Trust. ‘It massively interferes pinch each aspects of life: social, educational, and careers.’
One problem is that IH is easy confused pinch different conditions, including depression. It intends those affected extremity up connected medicine they don’t need, that causes side-effects, aliases their problems are dismissed arsenic ‘laziness’.
Despite her aggravated sleepiness, Sarah passed her GCSEs but ‘flunked’ her A-levels because she was ever exhausted.
‘I’d spell location successful nan mediate of nan time arsenic I couldn’t conflict nan hopeless request to nap and slumber profoundly — moreover if I’d slept good nan nighttime before.’
Following repeated trips to nan GP, who ran humor tests for conditions that mightiness origin tiredness, specified arsenic anaemia, Sarah was told she was ‘just young and tired’, and to ‘get connected pinch it’.
Excessive daytime drowsiness is simply a communal denotation mostly and whitethorn subordinate to insufficient slumber value aliases quantity, says Dr Alanna Hare, a advisor astatine nan Royal Brompton and Harefield Hospitals, specialising successful slumber and breathing.

There are galore causes, ranging from obstructive slumber apnoea (when breathing stops many times during nan night) to a neurological upset specified arsenic narcolepsy, medicine aliases psychiatric disorders, Dr Hare adds.
First identified successful nan 1970s, IH affects an estimated 1 successful 25,000 adults, though Dr Reading believes nan existent fig is 1 successful 5,000. ‘It is somewhat much communal successful females, pinch highest incidence successful nan teens, though it’s often not diagnosed for galore years.’
The information is diagnosed only erstwhile different possibilities person been ruled out. (Idiopathic intends nary known cause.)
‘We really don’t cognize what’s down it,’ says Dr Reading. ‘Brain scans looking astatine nan main slumber centres, specified arsenic nan hypothalamus, are normal.’
However, location are unique characteristics. ‘IH is champion described arsenic a syndrome of excessive slumber request specified that subjects person fantabulous overnight sleep, often achieving 9-11 hours of good-quality sleep, but still require naps, usually unplanned, during nan day,’ he explains. Another motion is micro-sleeps — i.e. a three-second aliases truthful lapse ‘when personification appears awake but isn’t fully’.
‘Losing items astir nan house, aliases putting location keys successful nan fridge tin beryllium a motion of specified lapses’.
These lapses will sound acquainted to anyone who’s been sleep-deprived, but nan cardinal pinch IH is that these micro-sleeps hap moreover aft a afloat night’s sleep.
‘The sleepiness pinch IH is besides different from nan “fatigue” people get aft doing immoderate demanding intelligence aliases beingness activity — for illustration patients pinch chronic fatigue syndrome mostly do not autumn dormant if inactive aliases resting, whereas patients pinch IH do,’ he says.
Dr Reading adds: ‘Patients often trust connected a number of siren clocks, reporting terrible “sleep inertia” aliases “sleep drunkenness” successful nan greeting and emotion for illustration “zombies” for an hr aliases so. This is often nan worst denotation and hardest to treat.’
And dissimilar personification who is simply ‘not a greeting person’, who will mostly consciousness much alert arsenic nan time wears on, personification pinch IH will enactment tired each day.
This daytime tiredness tin make it difficult to clasp down a occupation — arsenic Sarah discovered erstwhile she deed her 20s.
‘I wanted to activity but couldn’t arsenic I could ne'er enactment awake agelong capable during agency hours,’ she says. ‘It was nan vexation of not being capable to activity connected my uni assignments that led to maine realising I had a superior problem and that it couldn’t conscionable beryllium my cognition — which was a communal consequence from astir group astir me.’
Beginning to interest that thing was earnestly wrong, aged 21, she consulted a different GP.
‘I wasn’t going retired aliases making love arsenic I was ever tired and avoided friends because nary 1 understood why I was truthful exhausted.’
She was yet referred to a slumber session successful 2004, wherever she saw Dr Reading, who diagnosed IH.
While test mostly rests connected a patient’s explanation of their symptoms, overnight testing successful a slumber laboratory tin help: it shows whether personification is getting bully value slumber and tin norm retired conditions specified arsenic slumber apnoea. How quickly a diligent falls dormant is besides assessed.
‘Most patients pinch IH will return an mean of 7 minutes aliases little to driblet off,’ says Dr Reading. (Ten minutes aliases longer is considered normal). Overnight testing tin besides uncover different signatures of IH — including ‘excessive “slow wave” slumber [deep sleep] which extends precocious successful nan night,’ explains Dr Reading. ‘In astir group nan deepest stages of slumber hap successful nan first 2 hours aft dropping off, but successful IH nan heavy slumber tin widen aliases recur precocious successful nan nighttime and interfere pinch waking up easily.’
Dr Hare adds: ‘Because we do not yet afloat understand nan underlying illness process and we person nary biomarkers it is very difficult to make a patient diagnosis.’
This besides intends that curen for IH is for nan symptoms only.
As good arsenic psychostimulants (amphetamine-like drugs), location are newer narcotics specified arsenic modafinil (used to dainty ADHD) and Wakix (developed for narcolepsy). ‘These newer narcotics activity specifically connected nan “wake mechanism” portion of nan encephalon and person less side-effects — successful nan bosom for illustration — than amphetamines,’ says Dr Reading, which he says are nary longer nan first-line treatment, but whitethorn beryllium prescribed arsenic a back-up option.
‘Most patients amended connected medication, but it is comparatively uncommon to execute “normality”,’ he adds.
Sarah did not consciousness herself connected nan prescribed amphetamines: ‘I was jittery, talking truthful accelerated group couldn’t support up. It kept maine awake, but changed my personality — I felt I was ever racing done life.’
She took them for six years, and besides tried Wakix, nevertheless she stopped because of nan side-effects — utmost headaches, ocular problems and accelerated heartbeat —and because she started trying for a family.
She had her first babe successful 2014 and went connected to go a mother of three. ‘Being a mum to young kids erstwhile each you want to do is slumber was horrendous. I honestly don’t cognize really I stayed awake.’
She says she was besides very lonely arsenic immoderate relatives and friends doubted her diagnosis, telling her to ‘just threat retired of it — thankfully my partner was a existent support’.
Lack of knowing astir nan information contributes to terrible frustration, ‘which tin germinate into important temper disorder specified arsenic anxiety,’ says Dr Reading. ‘The resulting debased temper aliases worry are past presumed to beryllium causing nan excessive sleepiness — but location is nary evidence that slump causes existent hypersomnolence [excessive sleepiness], it’s astir invariably nan different measurement round!’
Furthermore, nan narcotics utilized to dainty temper disorders tin impact nan sleep-wake rhythm and worsen nan inability to aftermath up successful nan greeting aliases activity a accepted displacement pattern, says Dr Reading.
Apart from due medication, a slumber master whitethorn beryllium capable to counsel connected manner changes that mightiness help: from timing of meals to sticking, wherever possible, to regular slumber and aftermath times. The bully news is that, ‘in my acquisition IH does amended arsenic group get older’, says Dr Reading.
Meanwhile, Sarah does nan champion she tin without medication. She manages to activity portion time, but still struggles.
‘No matter really overmuch slumber I get astatine nighttime I americium exhausted by mid morning,’ she says. She’s started a Facebook support group for different sufferers, Idopathic Hypersomnia UK.
She adds: ‘One of nan hardest things is that erstwhile you explicate it to group they still don’t judge you.’
