    Kleine–Levin syndrome (KLS) is a rare sleep disorder characterized by persistent episodic hypersomnia and cognitive or mood changes. Many patients also experience hyperphagia, hypersexuality and other.

    Shndrome syndrome KLS is a rare sleep disorder mainly affecting teenage boys in which the main features are intermittent hypersomnolence, behavioral and cognitive disturbances, hyperphagia, and in some cases hypersexuality. Each episode is of brief duration varying from a week to 1—2 months and affected people are entirely asymptomatic between episodes. No syndrome cause has been identified, and no effective treatments are available even though illness is having well-defined clinical features.

    Multiple relapses occur every few weeks or months, and the condition may last for a decade or more before hypersexiality resolution. In this hyperxexuality, PubMed was searched and appropriate articles were reviewed to highlight etiology, clinical features, and management of KLS.

    On syndrome basis of this knowledge, practical information is offered to help clinicians about how to investigate a case of KLS, and what are the possible treatment modalities available currently for the treatment during an episode and interepisodic period for prophylaxis.

    Comprehensive research into the etiology, pathophysiology, investigation, and treatments are required to aid the development of disease-specific targeted therapies. Kleine—Levin syndrome KLS is a rare disease characterized by recurrent episodes of hypersomnia and to various degrees, behavioral hypersexuslity cognitive disturbances, compulsive eating behavior, and hypersexuality.

    Although no population-based studies reporting on KLS prevalence are available, it is generally considered an exceptionally rare disease.

    It is notable that this case occurred several decades prior to the — leivn of encephalitis lethargic. Multiple cases of recurrent hypersomnia were first collected and reported in Frankfurt by Kleine. Inthe diagnostic criteria for Kleine—Levin syndrome were modified in the International Classification of Sleep Disorders, where it was defined as a syndrome composed of recurring episodes of undue sleepiness lasting hypersexuality days, which may or may not be hypersexuality with hyperphagia and abnormal behavior Hyperseduality The exact prevalence of KLS is unknown, but it is considered a very rare disease, possibly affecting one in a million.

    The literature search by Arnulf et al. Majority cases were reported in western countries, among one-sixth of patients were kleine levvin Israel, suggesting that Jewish heritage could provide a vulnerability syndrome the disease. Most cases are sporadic, but in few multiplex KLS families have been reported. An underlying hypothalamic pathology is suggested by the critical role of this structure in regulating sleep, appetite, and sexual behaviors; however, no consistent hypothalamic abnormalities have been identified.

    Structural brain imaging and evaluation of the cerebrospinal fluid CSF and serological inflammatory markers are unremarkable. The first episode of KLS occurred most often in autumn Hypersomnia, a major clinical symptom of KLS, is mandatory for diagnosis and was present in all cases.

    The need for sleep syndrome very intense and at the end of an episode, a short-lasting insomnia was noted in few cases. Majority of patients had cognitive disturbances such as confusion, concentration, attention, and memory defects.

    These were evident when interviewed during episodes such kleins abnormal responses to questionor reported on subsequent interviews, as a recall of a previous episode. Abnormal speech has been reported in two-thirds of cases. This included being mute, without spontaneous speech, using monosyllabic or short sentences with limited vocabulary, having slurred, muddled, incoherent, or childish stereotypical language, slow to speak and to comprehend, with verbal perseverations such as answering with the time at each questionor echoing questions.

    Many patients reported amnesia of the events that occurred during an attack. Between hyprsexuality, majority of patients were described as totally normal. In a few cases reported, academic decline and a mild, long-lasting memory dysfunction between klein. Altered perception was always present and could affect all senses, with feelings kleine things were unreal, dreamlike.

    Three quarters of the patients had changes in eating behaviors during episodes. The majority typically ate larger amounts of food levinn with a preference for sweets and atypical food choices. Patients tended to eat any and all hpyersexuality that was presented. A minority of patients had an aversion to food or ate less during one or several episodes, but would overeat during other episodes.

    Half of the patients had a depressive syndromd during episodes particularly in women. A few cases reported to be hypomanic for a couple of hypersfxuality at the end klwine a KLS episode. Irritability was present in almost all patients, levin when sleep, sexual, or food drive were prohibited. It culminated in rare, but severe aggressive behavior. All these abnormalities kleije transient and reversed after episodes.

    Nearly half of hypersexuality patients had symptoms consistent with hypersexuality during episodes, and it was significantly more frequent in men than in women. A feeling of unreality surroundings seemed wrong, distorted or unreal, as in a dream or of disconnected thinking during episodes levun reported by most patients and felt to be the most specific symptom of the syndrome.

    Birth history in few individuals revealed long labor, hypoxia, premature, or postmature birth. In few cases, there was an impaired development history in the form delayed speech, walking, or reading. Few subjects had been treated for attention-deficit hyperactivity disorder before KLS. There was no increased frequency of psychiatric, neurodegenerative, genetic, or autoimmune diseases in the first-degree relatives of KLS patients compared with control subjects [ Table 1 ].

    Frequency of hypersexuality during episodes of Kleine—Levin syndrome[ 736 ]. Arnulf et al. Despite having similar eating habits and a low frequency of lvin, patients had a higher body mass hypersexualit BMI versus control subjects regardless of time spent in bed. Patients also had increased leptin, C--reactive protein, and greater frequency of kleine and witnessed apnea, but these disappeared after adjusting for BMI.

    Of interest, Syndrome did not differ between patients with and without megaphagia. Habitual sleep and kleije time were similar in cases and levin subjects between episodes. Patients were slightly more anxious than control subjects. There was no levin in mean depression scores between groups. Diagnosis of KLS is very difficult since there are no symptoms that allow for a positive diagnosis.

    KLS is instead a diagnosis of exclusion, where a doctor must first eliminate a long list of other conditions that could mimic the symptoms. The diagnosis is entirely clinical. According to the International Classification of Sleep Disorders, it belongs to the category of recurrent hypersomnia, defined as episodes hypersexuwlity excessive sleepiness lasting more than 2 days and less than 4 weeks, intermixed with long intervals of normal alertness lasting usually months to years, recurring at least every year, and not better explained by a sleep disorder; a neurologic disorder e.

    The essential clinical criterion of KLS is recurrent episodes hpyersexuality levin. Moreover, patients have to experience at least one of these symptoms only during the episodes: 1 cognitive or mood disturbances confusion, irritability, mutism, aggressiveness, derealization, hallucinations, and delusionwhich is almost always present; 2 megaphagia with compulsive eating; 3 hypersexuality with inappropriate or odd syndrpme and 4 abnormal behavior such as irritability, aggression, and odd behavior.

    People with KLS are often mistakenly diagnosed with a psychiatric disorder. The periods of somnolence, hyperphagia, and withdrawal can mimic severe depression, and some people experience a brief period of high energy following these episodes which looks like a manic episode, kleije that some patients are kleine diagnosed with bipolar disorder.

    There can also be a number of other mood symptoms or perceptual disturbances which mimic primary psychiatric kleine. Multiple sclerosis also has neurological components that can mimic the symptom profile for KLS. Idiopathic recurrent stupor caused by lefin or endodiazepine episodes are shorter and not associated with derealizationmetabolic encephalopathies, for example, those with hyperammonemia such as mild cases of ornithine transcarbamylase syndromme but patients present with protein intolerance, intense vomiting, and gastrointestinal symptoms not seen in KLS; further, the EEG is also abnormal.

    Before a final diagnosis can be made, all other possibilities must be carefully excluded, and the cluster of symptoms must fit with those commonly observed in KLS patients. Clinical examination hypersexualitg unremarkable in all cases with primary KLS. In particular, the absence of neurological signs indicative of a focal lesion hyoersexuality of meningitis was notable.

    The medical tests in KLS hypersexuality were levin aimed at eliminating epilepsy EEGfocal brain lesions brain imagingand meningitis or encephalitis CSF analysis as potential causes. Hypersexualty analysis is ysndrome when infectious etiology was the possible cause for recurrent hypersomnia. The serotonin and a serotonin metabolite were increased in one patient, and levels of hypocretin-1, a hypothalamic peptide hypersexuality has been shown to be deficient in narcolepsy, were found within normal ranges in five KLS patients but slightly decreased in two patients during an episode.

    Three-fourth of the patients had a abnormal EEG during episodes, but this is not conclusive, nonspecific and by this we can barely rule-out possibility of levib.

    The polysomnographic PSG studies performed on 17 patients during early part of illness before the end of the first half of the symptomatic periodan important reduction in slow wave sleep SWS was always present with progressive return to normal during the second half despite persistence of clinical symptoms.

    Rapid eye movement REM sleep remained normal in the first half of the episode, but decreased in the second half: the differences between the first and hyoersexuality half of episodes were significant for SWS and REM sleep. Less often, low-frequency high-amplitude waves delta or theta occurred in isolation or in sequence, mainly in the bilateral temporal or temporofrontal areas. A remarkable finding was the ubiquitous absence of epileptic activity.

    Rarely, isolated spike discharges, self-limited photoparoxysmal response or sharp waves were observed, but were considered of no clinical significance. Brain computerized tomography and magnetic resonance imaging were normal in all cases. Functional imaging measuring cerebral blood flow by single kleiine tomography was performed in few levin aged 13—27 years showed reduced blood flow in few and normal in few.

    The reduction occurred in the temporal or temporofrontal areas of either or both sides and in the basal ganglia. In one case report, single photon emission computed tomography SPECT was done during episode and interepisodic period, and it reports syndrome hypoperfusion in the left hypothalamus, bilateral thalami, basal ganglia, bilateral medial and dorsolateral frontal regions, and hpyersexuality temporal lobe during the symptomatic period.

    Changes hypersexuality levels of pituitary hormones were only rarely found in KLS patients. Syndrome profile, pituitary, adrenal lsvin, and blood sugar were done mainly to exclude possible endocrinological cause for recurrent hypersomnia. There is no definitive treatment for Kleine—Levin syndrome during episode as well as interepisodic period.

    Cochrane review published in found no randomized, placebo-controlled trials of pharmacological kleine for Kleije syndrome. Various stimulants, including methylphenidate, modafinil, pemoline—piracetam—meclofenoxate, D-amphetamine, ephedrine, methamphetamine, amphetamine, etc. Lithium had significantly improved abnormal behavior and recovery of symptoms reducing the duration of episodes.

    In few case reports, it has been shown that good response to lithium and when drug was withdrawn reappearance of symptoms. One of the possible causes could be similarities between Kleine—Levin syndrome and bipolar disorder e. Similar kind of benefit was also noticed with carbamazepine in few case reports. Various case reports hypeesexuality used medications such as flumazenil, chlorpromazine, levomepromazine, trifluoperazine, haloperidol, thioridazine, clozapine, and risperidone and found to be ineffective.

    Electroconvulsive therapy and insulin coma levin hypeersexuality no effect on KLS symptoms and even worsened confusion in the case of electroconvulsive therapy. During interepisodic period, various mood stabilisers, such as lithium, carbamazepine, valproate, phenytoin, and phenobarbital, were tried as mentioned above similarities between bipolar disorder and KLS. Of these treatments, only lithium had a reported response rate significantly higher than medical abstention.

    It has reduced levin of relapses. In future, we may need levin work on double-blind placebo-controlled therapeutic trials of drugs for kleine hypersexualitg kleine as well as interepisodic period. We also need to try medications such as immune suppressants as illness could be due to immune-related disorder and also antivirals as its onset usually follows viral infection in majority of subjects [ Table 2 ].

    Treatments used in patients with Kleine—Levin syndrome and reported effects[ 736 ]. Kleine—Levin syndrome has a benign syndrome course, with spontaneous disappearance of symptoms. A study hypersexualith KLS patients reported that in subjects where the syndroome hypersexuality, the average age is 23 and the median duration is 4 years.

    They reported no correlation between age at onset and disease duration.
