Medical mystery about why a teen slept as much as 20 hours a day - The Washington Post

“It was rather scary,” Kristen recalled. “At archetypal we thought she was joking.”

That bizarre episode, which occurred successful September 2017, has been followed by 11 more, each lasting an mean of 10 days. Between episodes, Erin’s behaviour is normal.

For 2 1/2 years she and her parents, who unrecorded successful Lincoln, Neb., consulted pediatric neurologists, a neurosurgeon, an obstetrician-gynecologist and different specialists successful a mostly fruitless hunt to place the information that drastically alters her property and temporarily shuts down her beingness 2 oregon 3 times a year.

The diagnosis, made successful March 2020, was an tremendous relief. But it has required the Bousquets to header with continued uncertainty due to the fact that truthful small is known astir Erin’s disorder.

“The hardest happening for maine are the things I’ve missed retired on,” said Erin, a 19-year-old sophomore astatine the University of Nebraska astatine Lincoln. They see a precocious schoolhouse hoops championship, her 18th birthday, a household Christmas travel to Colorado and the commencement of her sophomore twelvemonth of college. Erin slept done them all.

Because her symptoms — disorientation and prolonged slumber — tin beryllium signs of a serious, adjacent life-threatening, illness, the unit astatine the urgent attraction session wherever Erin had been treated for strep told her parent to instrumentality her to an exigency room. A trial for infectious mononucleosis, a contagious microorganism communal among adolescents and young adults that causes profound fatigue was antagonistic and a speedy neurological exam was normal. Erin was sent home.

A time aboriginal she saw the pediatrician who had treated her since birth. During the sojourn “she was slumping down successful her chair” arsenic if she was astir to descent onto the exam country floor, Kristen recalled. “Her look was conscionable empty.”

At that constituent Erin was sleeping astir around-the-clock, waking to eat, portion and spell to the bathroom. She became aggravated erstwhile idiosyncratic tried to rouse her oregon support her awake. She spoke successful a whisper, giving one-word answers to questions. Her behaviour was childish, sometimes obnoxious and unfiltered — a stark opposition to her accustomed polite, even-keeled self.

The pediatrician “was stumped too,” recalled Kristen, who had started keeping a elaborate log of her daughter’s symptoms, tests and treatments that would beryllium peculiarly utile later.

Erin’s doc thought she mightiness person been unknowingly drugged astatine a enactment oregon was utilizing amerciable drugs, possibilities her parents vehemently rejected. They noted that she was an grant pupil progressive successful aggregate sports and different extracurricular activities who had a ample radical of friends.

After a antagonistic cause test, the pediatrician suggested she mightiness person a psychiatric occupation and recommended medicine for anxiousness and depression. Kristen, skeptical that the occupation was psychological, insisted alternatively connected a referral to a pediatric neurologist. The neurologist admitted her to a hospital.

The psychiatrist who saw her during her three-day enactment said helium didn’t cognize what was incorrect but believed the origin was astir apt physical, not psychological.

Neurologists initially suspected a signifier of autoimmune encephalitis, a superior inflammation of the encephalon requiring urgent treatment. The disease, besides known arsenic anti-NMDA receptor encephalitis, triggers unusual behaviour that mimics psychosis. Its causes see a benign ovarian tumor called a teratoma. But scans of Erin’s brain, abdomen and pelvis — on with an EEG that measures encephalon waves and tests of her humor and spinal fluid that were sent to the Mayo Clinic for investigation — turned up nary signs of a tumor, corruption oregon encephalitis.

Eight days aft the unusual behaviour started it was arsenic though “someone had flipped a switch,” her parent recalled. Erin was backmost to her aged aforesaid but remembered small of what had happened. After a fewer nights of insomnia, her slumber signifier returned to normal.

An MRI scan of Erin’s encephalon performed portion she was hospitalized had uncovered thing unusual: a Chiari malformation, successful which encephalon insubstantial extends into the spinal canal. A neurosurgeon thought the Chiari mightiness person caused her symptoms, though they were hardly emblematic — a Chiari usually causes crushing headaches, cervix symptom and equilibrium problems. He ordered a repetition scan successful six months.

In May 2018 aft a 2nd scan showed nary change, the surgeon said helium doubted the Chiari had thing to bash with the episode. No further attraction was necessary, helium told the Bousquets, unless Erin developed caller symptoms. The family, relieved that Erin did not person a superior encephalon malformation, moved on. Everyone hoped it was, arsenic 1 doc speculated, “a weird virus.”

But successful June 2018, 8 months aft the archetypal episode, it happened again.

This clip Erin did not person strep. “She woke up fine,” but a fewer hours aboriginal her behaviour changed abruptly and the slumber marathon began, Kristen recalled. Doctors, who were again acrophobic astir encephalitis, admitted her and recovered nary motion of the disease.

Erin was discharged 3 days later. “The information that everything came backmost cleanable was great,” her parent said. “But astatine the aforesaid clip you’re precise frightened … I got tons of blank stares from doctors. Nobody had ever seen thing similar this.”

Over clip a signifier seemed to look successful the log Kristen was keeping. The episodes often started the time aft Erin’s play began. During it she craved foods she seldom ate, including a circumstantial sugary kids’ cereal, 1 marque of chickenhearted nuggets, maize and crystal pick sandwiches.

“She couldn’t travel the simplest instructions,” Kristen remembered. “I would archer her to instrumentality a ablution and locomotion successful and find her lying connected the level of the bathroom, her feet propped up connected the toilet.”

Her property alteration was unnerving and her uncharacteristic defiance sometimes embarrassing. She would “tell the infirmary radical to get retired of her room,” her parent remembered. Once she tried to propulsion retired her IVs.

The extremity of an occurrence was marked by a headache, euphoria, antithetic talkativeness and a fewer nights of insomnia, during which Erin and her relieved parent caught up connected what she had missed.

Each clip Kristen struggled to tamp down her worries astir the future. “My biggest fearfulness was what if this happens again and she ne'er comes retired of it and she’s ne'er Erin again?”

The evident nexus to Erin’s menstrual rhythm led to a caller absorption connected a imaginable hormonal cause: premenstrual dysphoric disorder (PMDD), though its predominant symptoms see anxiousness and depression, not altered behaviour and marathon sleeping.

In summertime 2018 Erin saw a fertility specializer who ordered humor tests, past prescribed injections to antagonistic a crisp driblet successful 2 hormones that the obstetrician-gynecologist thought mightiness beryllium triggering the episodes. Another trial showed mild insulin resistance, which tin beryllium a precursor to Type 2 diabetes. But six months of a diabetes cause on with hormone injections did not forestall episodes successful March and July 2019.

“It seemed similar it was mostly proceedings and error,” Kristen recalled of the treatments, which besides included vitamins and changes to Erin’s diet.

Kristen said she and her husband, Greg, saw their relation arsenic advocates for their daughter, though they often felt unsure astir what to bash oregon wherever to turn. They routinely asked for referrals and erstwhile a doc appeared disinterested, moved on.

“We were determined to find the close doc and not to conscionable settee for an casual reply oregon commencement random” drugs, Kristen said. The quest for a diagnosis, they believed, had to beryllium balanced against their reluctance to disrupt Erin’s beingness “even much than the 20 missed days of the twelvemonth already did.”

In aboriginal 2020 the fertility specializer recommended that Erin consult Omaha neurologist Robert Sundell.

At the commencement of the March 18 appointment, Sundell said Kristen handed him a six-page, single-spaced chronology and launched into Erin’s story, starting astatine the beginning. “I told him everything that had happened,” she said.

Erin and her parent retrieve that Sundell, who is present connected the unit of Methodist Health System, listened attentively, past excused himself.

He returned astir 15 minutes aboriginal with quality that floored them. He told them helium believed Erin had Kleine-Levin Syndrome (KLS), a uncommon and little-known slumber disorder. Although 70 percent of cases impact teen boys, KLS is besides known arsenic “Sleeping Beauty Syndrome.”

Kristen said she remembers exclaiming, “Oh my gosh, that’s precisely what this is!”

Episodes typically past a fewer days to a fewer weeks and recur unpredictably. Childish oregon disinhibited behavior, irritability, accrued appetite, nutrient cravings and disorientation are communal during episodes, arsenic is amnesia.

Between episodes radical with KLS usually relation normally. The origin of the upset is chartless and whitethorn beryllium the effect of familial factors, an autoimmune effect oregon a malfunction successful parts of the encephalon that govern slumber and appetite.

No attraction has been recovered to beryllium mostly effectual successful preventing KLS, which tin beryllium misdiagnosed arsenic slump oregon psychosis. The upset often spontaneously resolves within astir a decade of the archetypal episode, though it tin recur later.

“With the retrospectoscope it was beauteous clear,” Sundell said, utilizing aesculapian slang for hindsight. “There’s not overmuch other this could be,” helium said, adding that Erin “meets each the criteria.” Triggers see an infection, intoxicant oregon the commencement of a period, helium noted.

The neurologist said that portion helium knew of KLS, helium had ne'er seen a diligent with it. In Erin’s lawsuit extended investigating had already ruled retired a encephalon tumor, corruption oregon different causes. “Most atrocious things get worse,” Sundell said, noting that Erin was steadfast betwixt episodes.

Sundell said helium contacted different neurologists successful Omaha, but nary was acquainted with the disorder. He besides spoke with a slumber upset specializer astatine the Mayo Clinic who offered to spot Erin; the Bousquets declined. Erin present sees Sundell annually.

“Our attack has been watchful waiting and the anticipation that this goes away,” the neurologist said.

Kristen said that she has recovered interaction with different families she met done the KLS Foundation to beryllium mostly reassuring. She is particularly grateful to Sundell who has been unusually disposable and unfastened to discussing imaginable therapies. The household hopes to enactment successful a Stanford University study of the disorder.

But each caller episode, Kristen said, arouses “all the bittersweet and frightened feelings arsenic I recognize we person nary control. When she is sick, our lives stop.”

Erin has tried to set to the information that she ne'er knows erstwhile she mightiness beryllium retired of committee for astir 2 weeks arsenic she was successful August, astatine the opening of her sophomore year.

“It’s benignant of hard to explain,” she said.
