Prader-Willi syndrome (PWS) is a genetically determined neurodevelopmental disorder characterized by mental retardation and distinct physical, behavioral, and psychiatric features. Based on parents' questionnaires, we examined the prevalence of behavioral and psychiatric disorders of 165 persons with PWS aged 2-31 years in Japan. The data were analyzed comparing four different age groups with PWS: group 1, 2-5 years (n=34); group 2, 6-11 years (n=57); group 3, 12-17 years (n=45); and group 4, 18-31 years (n=29). Further, we compared the results of our PWS group 4 with those of 42 age-, gender-, and intelligence level-matched intellectual disability (ID) individuals without PWS. Our results showed that repetitive speech and stubbornness were prominent from early childhood and other behavioral problems such as hyperphagia, stealing food, temper tantrums, lying, and emotional lability tended to be more frequent with age among persons with PWS. Moreover, young adults with PWS have significantly higher rates of behavioral and psychiatric disorders than IDs without PWS, such as stubbornness, hyperphagia, temper tantrums, self-injurious behavior (skin picking), hypersomnia, inactivity, and delusion. Degree of obesity was not necessarily related to behavioral and psychiatric features associated with PWS. Our findings revealed that persons with PWS are more vulnerable to behavioral and psychiatric disorders particularly in young adulthood compared to those with ID from other etiologies in Japan.

Atypical depression is defined as a type of depression that responds preferentially to monoamine oxidase inhibitors. In addition to mood reactivity, symptoms of atypical depression include hypersomnia, hyperphagia or weight gain, leaden paralysis, and a long-standing pattern of rejection sensitivity or interpersonal sensitivity. Over the years, atypical depression has been associated with or identified as nonendogenous depression, anxiety, reverse vegetative shift, chronic pain, bipolar disorder, and rejection sensitivity. This presentation discusses the history of the identification of atypical depression, starting with its initial identification in 1959, and describes the important studies of atypical depression and its treatment by various research groups during the past 50 years. The presentation concludes by differentiating between typical and atypical depression and detailing of some of the clinical characteristics of atypical depression.

The concept of atypical depression has evolved over the past several decades, yet remains inadequately defined. As currently defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR), the main criterion of atypical depression is the presence of mood reactivity in combination with at least 2 of 4 secondary criteria (hypersomnia, hyperphagia and weight gain, leaden paralysis, and oversensitivity to criticism and rejection). The focus on mood reactivity as the primary distinguishing criterion remains questionable among researchers who have been unable to verify the primacy of this symptom in relation to the other diagnostic criteria for atypical depression. A model challenging the DSM-IV-TR definition of atypical depression has been developed, redefining the disorder as a dimensional nonmelancholic syndrome in which individuals with a personality subtype of "interpersonal rejection sensitivity" have a tendency toward the onset of anxiety disorders and depression, thereby exhibiting a variety of dysregulated emotional and self-consolatory responses. This reformulated definition of atypical depression (in arguing for the primacy of a personality style or rejection sensitivity as against mood reactivity) may lead to a better understanding and recognition of the disorder and its symptoms as well as other "spectrum" disorders within the scope of major depression.

We report the first episode of Kleine-Levin (KLS) syndrome in a 17-year-old male. The illness onset, clinical features, neuropsychological evaluation and polysomnographic recording are described. Typical symptoms hypersomnia, hyperphagia and sexual disinhibition were observed besides behavioral disturbances, polysomnographic and neuropsychological alterations. Behavioral disturbances similar to a manic episode including psychotic symptoms were relevant. The pharmacologic treatment included lithium, methylphenidate and risperidone. The introduction of risperidone aimed the control of psychotic symptoms and the persistent manifestations of hypersexuality after sleepiness control and to the best of our knowledge there are no other reports regarding risperidone use for KLS in the literature.

Idiopathic hypothalamic dysfunction is a rare disorder presenting at age 3-7 years. Severe hypothalamic and brainstem dysfunction leads to death in 25% of patients. The disease is presumed to be autoimmune, or in some cases paraneoplastic. No successful treatment has been reported. Patient V. developed hyperphagia, hypersomnia, and extreme aggression at age 7 years, accompanied by episodes of hyperthermia, hypothermia, sinus bradycardia, hypernatremia, hyponatremia, persistent hyperprolactinemia, hypothyroidism, and growth-hormone deficiency. At age 9 years, a diagnosis of idiopathic hypothalamic dysfunction was rendered, and immunoglobulin therapy was commenced. Nine courses of immunoglobulins, at a dose of 2 g/kg every 4 weeks, were administered. Reproducible improvements in behavior and no further episodes of hyponatremia or hypernatremia and sinus bradycardia were evident. The endocrinologic abnormalities and poor thermoregulation remained. Administration of immunoglobulins during late stages of idiopathic hypothalamic dysfunction led to improvement in some but not all signs. Assuming an autoimmune basis for this disorder, treatment during early stages of disease should be more effective. To facilitate such early treatment, increased awareness of this disorder is necessary, to allow for early diagnosis.

Preliminary data suggest that hypericum extract LI160 is effective in atypical depression. Reported is the outcome of an 8-week double-blind, placebo-controlled, randomized trial of 600 mg LI160 vs. placebo in patients with vegetative features of atypical depression, i.e. hyperphagia or hypersomnia. One-hundred (100) patients with mild and 100 patients with moderate severity of a major depression according to ICD-10 were randomized. Patients needed to meet a score of 2 in at least one of the items 22-26 of the Hamilton-Depression-Rating-Scale (HAM-D) 28-item version and episode duration of at least 3 months. The primary outcome variable was the relative change of the HAM-D(17) from Baseline. Secondary outcome variables were the depression sub-score of the Patient Health Questionnaire (PHQ-9), the Clinical Global Impression (CGI), a patient's satisfaction scale, the Hamilton-Anxiety-Scale (HAM-A) and the sum score of atypical vegetative symptoms of the HAM-D(28). The percentage reduction of the HAM-D(17) for LI160 compared to placebo approached statistical significance (p=0.051) in the Full Analysis Set (FAS)-population. Using the conventional criterion of the absolute reduction of the HAM-D(17) significance was achieved (p<0.05). No significant benefit could be observed for the sum score of the atypical vegetative items of the HAM-D(28;) however, the sum score of the hypersomnia items (items 22-24) showed a significant superiority for LI160. The HAM-A, PHQ-9, and CGI-I scales demonstrated superiority of LI160 (p<0.01). Confining the analysis to moderately depressed patients, a highly significant benefit for the primary outcome variable was revealed. The study supports the beneficial effect of LI160 in depression with atypical features and the validity of the definition of atypical depression on the basis of reversed vegetative signs. Further, it identifies the PHQ-9 as a useful outcome variable in this population.

Congenital central hypoventilation syndrome (CCHS) is a rare disorder with uncertain nosology that usually presents early in life. The syndrome is characterized by ventilatory response impairment to carbon dioxide and may result in respiratory failure at birth. Recent reports have identified a similar clinical presentation beyond infancy called late-onset central hypoventilation syndrome (LO-CHS) as a disease continuum of CCHS with similar and overlapping pathophysiology. However, some have proposed that the syndrome accompanied by hypothalamic dysfunction (HD) be classified as a distinct clinical entity, LO-CHS/HD. To the best of our knowledge, the case reported herein is the oldest case of LO-CHS/HD in childhood, at 13 years old. He suffered from recurrent pulmonary edema, acute convulsive seizures, hypersomnia, hyperphagia, obesity, impaired glucose tolerance test, and hypercapnia, diagnosed as LO-CHS/HD, and was successfully treated with nasal bi-level positive airway pressure.

Seasonal affective disorder (SAD) is a recently described mood disorder characterized by recurrent winter depressive episodes and summer remissions. The symptoms of SAD include DSM III-R criteria for recurrent major depression, but atypical depressive symptoms predominate with hypersomnia, hyperphagia and carbohydrate craving, and anergia. Seasonal affective disorder is effectively treated by exposure to bright light (phototherapy or light therapy), a novel antidepressant treatment. The authors review the syndrome of SAD, hypotheses about its pathophysiology, and the use of phototherapy to treat the disorder.

Obesity is associated with several symptoms that are components of the diagnostic criteria for major depressive disorder (MDD). Compared with nonobese individuals, obese individuals report more fatigue, sleep disturbance, and overeating. Obesity might, therefore, impact the psychometric properties of the MDD criteria. The goal of the present report from the Rhode Island Hospital Methods to Improve Diagnostic Assessment and Services project was to examine the impact of obesity on the psychometric characteristics of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition symptom criteria for major depression. Two thousand four hundred forty-eight psychiatric outpatients were administered a semistructured diagnostic interview. We inquired about all symptoms of depression for all patients. The mean sensitivity of the 9 criteria in the nonobese and obese patients was nearly identical (74.6% vs 74.3%). The mean specificity was slightly higher in the nonobese patients (82.0% vs 79.5%). No symptom was more specific in the obese than the nonobese patients, whereas the specificity of increased appetite, increased weight, and fatigue was more than 5% lower in the obese patients. Increased appetite, increased weight, hypersomnia, and fatigue had a higher sensitivity in the obese than the nonobese patients, whereas decreased appetite, weight loss, and diminished concentration had a higher sensitivity in the nonobese than the obese patients. Thus, although there were small differences between obese and nonobese patients in the operating characteristics of some symptoms, the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for MDD generally performed equally well for obese and nonobese patients.

Kleine-Levine Syndrome (KLS) is a disorder characterized by a triad of periodic hypersomnia, hyperphagia, and hypersexuality. KLS, although more common in young males, it has also been seen in females. Treatment options available for its management include mood stabilisers like lithium, stimulants like amphetamines, antidepressants and other options including electroconvulsive therapy. Modafinil is one of the new stimulant medications approved for narcolepsy. Herein, we report a young female with KLS and showing favorable response to modafinil. More data is required to establish the effectiveness of modafinil in this syndrome.
