Abstract
Parasomnias usually present in childhood and resolve spontaneously. The diagnosis of non-rapid eye movement-related parasomnias is mainly based on clinical descriptors and can be challenging. Rapid eye movement-related parasomnias may index an underlying psychiatric disorder. Even if benign, parasomnias can affect quality of life. Pediatricians and child psychiatrists should be familiarized with these sleep disorders and suggest adequate sleep hygiene, avoidance of sleep deprivation, and regular bedtimes even on weekends as the first step in management of these disorders. Clinicians should pursue the opportunity for tailoring treatments and consider referral to a sleep expert when indicated.

Abstract
Non-rapid eye movement (NREM) sleep parasomnias are recurrent abnormal behaviors emerging as incomplete arousals out of NREM sleep. Mounting evidence on NREM sleep parasomnias calls for an update of clinical and therapeutical strategies. In the current review, we summarize the state of the art and provide the necessary background to stimulate a critical revision of diagnostic criteria of disorders of arousal (DoA), the most common NREM sleep parasomnia. In particular, we highlight the poor sensitivity of the diagnostic items related to amnesia and absence of conscious experiences during DoA episodes, encourage the role of video-polysomnography and home-video recordings in the diagnostic and treatment work-up, and suggest three levels of diagnostic certainty based on clinical and objective findings. Furthermore, we highlight current gaps of knowledge that prevent the definition of standard guidelines and future research avenues.

Abstract
The current narrative review summarizes and examines several theories of panic disorder (PD) including biological theories, encompassing neurochemical factors, metabolic and genetic theories, respiratory and hyperventilation theories and cognitive theory. Biological theories have informed the development of psychopharmacological treatments; however, they may be limited in their utility given the efficacy of psychological treatments. In particular, behavioral and, more recently, cognitive models have garnered support due to the efficacy of cognitive-behavior therapy (CBT) in treating PD. The role of combination treatments has been found to be superior in the treatment of PD in particular cases, lending support for the need for an integrated approach and model for PD given that the etiology of PD is complex and multifactorial.

Abstract
Sleep terrors (STs) are sleep disorders characterized by abrupt arousal from sleep with autonomic hyperactivity and inappropriate behavior. Though a common condition in childhood that usually affects children between 4 and 12 years of age, STs, however, may be present even in adulthood. The exact etiology of STs is not known yet, however, several hypotheses have been proposed over the years, identifying some potential genetic, neurodevelopmental, or other causes. Nevertheless, a useful pathophysiological model identified a common cascade of predisposing, priming, and precipitating factors, which could help to explain and sometimes prevent STs. Establishing a correct diagnosis is mandatory for appropriate management, as several conditions (such as other parasomnias or nocturnal seizures) may mimic STs. Furthermore, we also described some conditions which can be comorbid to STs, like some medical or psychological disorders. A number of treatment options have been proposed, ranging from only sleep hygiene practices to pharmacological therapies; we reviewed some of the most prominent ones. In spite of the fact that STs have long been considered benign disorders, which tend to reduce spontaneously over the years, they may have unexpected consequences on the child but also on the caregivers.

Abstract
Nocturnal panic refers to waking in a state of panic without obvious triggers, experiencing the same symptoms as panic attacks that occur while awake. Interrelationships between daytime and nocturnal panic symptoms have not been examined despite theories suggesting panic symptoms perpetuate one another in a forward feedback loop. The current study compared associations between symptoms in daytime and nocturnal panic using network analysis. Network theory conceptualizes symptoms as causing one another, rather than originating from a latent variable (i.e., a disorder). Given that nocturnal panic originates from sleep stages without cognitive activity, cognitive symptoms were expected to be more central in daytime panic networks than nocturnal panic networks. Prior literature indicates similar nocturnal and daytime panic severity; thus, we expected that panic groups would report equivalent panic symptom severity. An online community sample (N = 215) provided panic symptom history. Panic network structures did not differ, although the daytime panic network produced stronger and more numerous connections between physical and cognitive symptoms. The nocturnal panic group, however, reported more severe cognitive symptoms than the daytime panic group. These results challenge biologically-focused nocturnal panic theories and suggest a more significant role of cognitive symptoms in perpetuating nocturnal panic attacks once the individual awakens.

Abstract
OBJECTIVE/BACKGROUND Nocturnal panic involves experiencing panic attacks out of a sleeping state without obvious causes. Roughly half of patients with panic disorder will experience nocturnal panic in addition to panic attacks while awake, or daytime panic. Like daytime panic, nocturnal panic also occurs in other disorders such as PTSD. The Fear of Loss of Vigilance theory is currently the only model available to explain nocturnal panic. It suggests nocturnal panickers fear states in which they cannot easily react to or protect themselves from danger. The current study sought to expand upon the existing theory by including constructs from the broader anxiety literature. Nocturnal panickers were expected to report higher scores on these measures when compared to daytime panickers and non-panickers. PARTICIPANTS A sample of 166 participants were screened for panic history. METHODS Participants completed self-report measures regarding panic attacks, fear of sleep, intolerance of uncertainty, responsibility for harm, and fear of loss of vigilance. RESULTS Measures of fear of sleep and responsibility for harm successfully differentiated nocturnal from daytime panickers, whereas measures of intolerance of uncertainty and fear of loss of vigilance did not. CONCLUSIONS These results provide partial support for the Fear of Loss of Vigilance theory. Modifications to the theory to incorporate additional constructs are suggested.

Abstract
Sleep disorders and nightmares are core symptoms of post-traumatic stress disorder (PTSD). The relationship seems to be bidirectional, and persistent disturbed sleep may influence the course of the disorder. With regard to sleep quality, insomnia and nocturnal anxiety symptoms, as well as nightmares and stressful dreams, are the most prominent sleep symptoms. Polysomnographic measurements reveal alterations of the sleep architecture and fragmentation of rapid eye movement sleep. In addition, sleep disorders, such as sleep-related breathing disorders and parasomnias are frequent comorbid conditions. The complex etiology and symptomatology of trauma-related sleep disorders with frequent psychiatric comorbidity require the application of multimodal treatment concepts, including psychological and pharmacological interventions. However, there is little empirical evidence on the effectiveness of long-term drug treatment for insomnia and nightmares. For nondrug interventions, challenges arise from the current lack of PTSD-treatment concepts integrating sleep- and trauma-focused therapies. Effective therapy for sleep disturbances may consequently also improve well-being during the day and probably even the course of PTSD. Whether early sleep interventions exert a preventive effect on the development of PTSD remains to be clarified in future studies.

Abstract
Paroxysmal events during sleep can be classified into parasomnias, sleep-related movements, psychiatric events, neurologic events, or medically related events. Diagnosis can be difficult because of the frequent overlap of clinical descriptors and lack of diurnal findings. We report a case of a 68-year-old man who presented to the hospital complaining of awakening from sleep with numbness, which was followed by an indescribable odd feeling. We discuss overlapping clinical features of nocturnal panic and sleep-related epilepsy.

Abstract
Panic and sleep disturbances are established risk factors for suicide. Nocturnal panic attacks, which occur out of sleep, represent an intersection of these risk factors. Only one study to date has examined this relationship, but measured suicidality as a unitary construct. This represents a significant gap in the literature, considering most individuals who think about suicide do not make a plan and most who make a plan never make an attempt. We sought to expand upon existing research by examining how nocturnal panic relates to suicidal ideation, plans, and attempts separately. We predicted nocturnal panic would be associated with more suicidal ideation, plan, and attempt history than daytime only panic and no panic. Participants recruited from an online community sample were thoroughly screened for nocturnal and daytime panic history and completed questionnaires about past suicidal ideation, plans, and attempts. Nocturnal and daytime panic groups did not differ in past suicidal ideation or plans, but both groups exceeded the non-panic group. The nocturnal panic group reported more suicide attempts than the daytime and non-panic groups and judged themselves as more likely to make an attempt in the future. These results indicate a promising avenue for future research and suicide prevention efforts.

Abstract
Insomnia is the most commonly reported symptom of posttraumatic stress disorder (PTSD), with at least 70% of patients with PTSD reporting disturbed sleep. Although posttraumatic insomnia has traditionally been conceptualized as a consequence of PTSD, it is the most likely symptom to not remit following otherwise successful PTSD treatment. This suggests that the relationship between PTSD and insomnia is more complex, such that they likely share underlying pathological mechanisms and that factors non-specific to PTSD maintain chronic trauma-induced insomnia. Although several theories and hypotheses have been presented to explain the relationship between PTSD and insomnia, neurobiological and psychological models have not been integrated, thereby limiting their comprehensiveness and abilities to inform effective intervention. Further, existing models have not addressed how acute trauma-induced insomnia becomes chronic. The present review examined models of PTSD and insomnia separately, as well as existing theorized mechanisms of their co-morbidity. The distinct characteristics of trauma-induced insomnia were also reviewed and presented to describe the unique clinical presentation of trauma-induced insomnia. Review and integration of the literature were used to propose an integrated model of chronic trauma-induced insomnia informed by a neuropsychobiological framework. Clinical implications and future research directions are presented and discussed.

Abstract
BACKGROUND Sleep terrors are common, frightening, but fortunately benign events. Familiarity with this condition is important so that an accurate diagnosis can be made. OBJECTIVE To familiarize physicians with the clinical manifestations, diagnosis, and management of children with sleep terrors. METHODS A PubMed search was completed in Clinical Queries using the key terms "sleep terrors" OR "night terrors". The search strategy included meta-analyses, randomized controlled trials, clinical trials, observational studies, and reviews. Only papers published in the English literature were included in this review. The information retrieved from the above search was used in the compilation of the present article. RESULTS It is estimated that sleep terrors occur in 1 to 6.5% of children 1 to 12 years of age. Sleep terrors typically occur in children between 4 and 12 years of age, with a peak between 5 and 7 years of age. The exact etiology is not known. Developmental, environmental, organic, psychological, and genetic factors have been identified as a potential cause of sleep terrors. Sleep terrors tend to occur within the first three hours of the major sleep episode, during arousal from stage three or four non-rapid eye movement (NREM) sleep. In a typical attack, the child awakens abruptly from sleep, sits upright in bed or jumps out of bed, screams in terror and intense fear, is panicky, and has a frightened expression. The child is confused and incoherent: verbalization is generally present but disorganized. Autonomic hyperactivity is manifested by tachycardia, tachypnea, diaphoresis, flushed face, dilated pupils, agitation, tremulousness, and increased muscle tone. The child is difficult to arouse and console and may express feelings of anxiety or doom. In the majority of cases, the patient does not awaken fully and settles back to quiet and deep sleep. There is retrograde amnesia for the attack the following morning. Attempts to interrupt a sleep terror episode should be avoided. As sleep deprivation can predispose to sleep terrors, it is important that the child has good sleep hygiene and an appropriate sleeping environment. Medical intervention is usually not necessary, but clonazepam may be considered on a short-term basis at bedtime if sleep terrors are frequent and severe or are associated with functional impairment, such as fatigue, daytime sleepiness, and distress. Anticipatory awakening, performed approximately half an hour before the child is most likely to experience a sleep terror episode, is often effective for the treatment of frequently occurring sleep terrors. CONCLUSION Most children outgrow the disorder by late adolescence. In the majority of cases, there is no specific treatment other than reassurance and parental education. Underlying conditions, however, should be treated if possible and precipitating factors should be avoided.

Abstract
The current report provides an updated review of sleep disturbance in posttraumatic stress disorder and anxiety-related disorders. First, this review provides a summary description of the unique and overlapping clinical characteristics and physiological features of sleep disturbance in specific DSM anxiety-related disorders. Second, this review presents evidence of a bidirectional relationship between sleep disturbance and anxiety-related disorders, and provides a model to explain this relationship by integrating research on psychological and neurocognitive processes with a current understanding of neurobiological pathways. A heuristic neurobiological framework for understanding the bidirectional relationship between abnormalities in sleep and anxiety-related brain pathways is presented. Directions for future research are suggested.

Abstract
Nocturnal panic involves waking suddenly from sleep in a state of panic, with no apparent cause, and affects more than half of patients with panic disorder. The Fear of Loss of Vigilance theory is the only proposed model for nocturnal panic, suggesting nocturnal panickers fear states in which they are unable to react to danger or protect themselves from threats. Prior work using a self-report questionnaire designed to test the theory (i.e., Fear of Loss of Vigilance Questionnaire; FLOVQ) was unsuccessful at differentiating nocturnal from daytime panickers. This study tested the theory using alternative measures to the FLOVQ. We predicted nocturnal panickers would show elevated responses to measures assessing fears of being unable to respond to or protect themselves from threats. A diverse community sample (N = 218) completed self-report measures related to panic attacks, intolerance of uncertainty, responsibility for harm, and anxiety sensitivity dimensions. Nocturnal panickers endorsed greater inhibitory intolerance of uncertainty and responsibility for harm, but not prospective intolerance of uncertainty, or anxiety sensitivity physical or cognitive concerns. This study provides support for the fear of loss of vigilance theory and suggests intolerance of uncertainty and responsibility for harm reduction be targeted in treatment for nocturnal panic attacks.

Abstract
The purpose of the current paper was to review the empirical literature on the cooccurrence of panic and epilepsy, in order to determine whether there is an increased risk of panic attacks and panic disorder among adults with epilepsy and an increased risk of epilepsy among adults with panic disorder. Given the overlap between panic and ictal fear, a preliminary aim of the current review was to critically evaluate the methodology used to differentiate between diagnoses of panic disorder and epilepsy in existing research. A literature search was conducted in relevant electronic databases, and articles that directly focused on panic and epilepsy among adults were selected for the current review (n = 17). Overall, results suggest that rates of epilepsy are elevated among individuals with panic disorder and that panic attacks are elevated among individuals with epilepsy, but rates of panic disorder among people with epilepsy are inconsistent. However, most studies did not use sufficiently rigorous methods to differentiate between panic disorder and epilepsy. Therefore, a critical next step in this area of research is to develop a standard procedure for differentiating ictal fear from panic attacks and panic disorder.

Abstract
Post-traumatic stress disorder (PTSD) is a serious psychiatric consequence of trauma that occurs in a proportion of individuals exposed to life-threatening events. Trauma-focused psychotherapy is often recommended as first choice for those who do not recover spontaneously. But many individuals require medications. In the US, only paroxetine (PRX) and sertraline (SRT) are FDA approved for PTSD. But response and remission rates with these medications are low, so numerous other pharmacologic interventions have been tried. To date, there has not been a systematic review of the data on what are the best next-step pharmacologic strategies for individuals who fail standard treatments. To that end, we review 168 published trials of medications other than PRX or SRT and provide a detailed analysis of the 88/168 studies that describe alternative pharmacologic interventions in patients refractory to other treatment. We also review clinical factors relevant to treatment-refractory PTSD; the neurobiology of extinction, as well as evidence-based psychotherapy and neuromodulation strategies for this condition.

Abstract
AbstractAnxiety disorders and insomnia significantly impair daily functioning. Similar underlying mechanisms may account for the high comorbidity of both disorders, and respective treatments share pharmacological and behavioural features. This review suggests the utility of an integrated CBT approach in the treatment of generalized anxiety, post-traumatic stress, and panic disorders, and comorbid insomnia. Other anxiety disorders were not explored because current data are limited or inconsistent. A comprehensive, non-systematic review of the literature was conducted to evaluate the treatment of comorbid anxiety and insomnia disorders, and data reveal shared pharmacological and behavioural features of insomnia and anxiety disorders treatment. However, research demonstrates that CBT maintains successful treatment results longer than drug therapies. Despite similar treatment approaches, there is a paucity of research that explores integrated CBT approaches for comorbid anxiety and insomnia disorders. This review suggests that future research should assess the impact of combined therapeutic approaches on the simultaneous reduction of anxiety disorders, insomnia, and relapse rates.

Abstract
OBJECTIVE Many patients with panic disorder (PD) experience nocturnal panic attacks. We investigated the differences in demographic variables and symptom characteristics as well as response to treatment among patients with primary day panic (DP), primary nocturnal panic (NP), and the coexistence of DP and NP (DP/NP), and discuss whether NP is a distinct disease category. METHOD One hundred one consecutive untreated patients with PD were enrolled and subsequently divided into the NP, DP, and DP/NP groups. The presence of 13 panic attack symptom items as well as scores on the Panic Disorder Severity Scale (PDSS) and the Pittsburgh Sleep Quality Index (PSQI) were compared among the groups. After 3 months of regular treatment, PDSS scores were assessed again to evaluate treatment response. RESULTS Nocturnal panic attacks of the participants were mostly reported to occur in the first tertile of nocturnal sleep. The number of males, onset age, and presence of choking sensation were significantly higher, and the PDSS score was significantly lower in the NP group compared with the other groups. The DP/NP group showed the highest PDSS score, and participants in this group were prescribed the highest doses of medication among all groups. Only diagnostic sub-category was significantly associated with treatment response. The total score for PDSS and PSQI correlated significantly only in the NP group. CONCLUSIONS DP/NP could be a severe form of PD, while primary NP could be a relatively mild subcategory that may partially share common pathophysiology with adult type night terror.

Abstract
Sleep disturbance commonly co-occurs with a range of psychiatric disorders. This is of concern given the accruing evidence that sleep is critically important for mood regulation, physical health, cognitive functioning, and quality of life. There is strong evidence that insomnia, even if it is comorbid with another psychiatric disorder, is treatable with cognitive behavioral therapy. There is a need to develop cognitive behavioral approaches to the other types of sleep disturbance often experienced by patients with psychiatric disorders, such as hypersomnia, reduced sleep need, delayed phase, nocturnal panic attacks, and nightmares. The possibility of developing a transdiagnostic treatment that comprehensively treats sleep disturbance for use across psychiatric disorders is discussed because (a) there are many disorders in which multiple types of sleep disturbance can be characteristic at one time or over the life-course of the disorder and (b) there are considerable challenges inherent to disseminating any new treatments but particularly many "disorder-specific" treatments.

Abstract
Panic disorder with agoraphobia is a psychological disorder. We are presenting a case report of male client, visted as out door patient in the counseling centre of National Institute of psychology. Client reported the symptoms such as palpitations, pounding heart, accelerated heart rate, sweating, trembling/shaking, feeling of choking, chest pain, discomfort, nausea, abdominal distress, feeling dizzy, lightheadedness, and fear of losing control when he is in the crowd. The signs and symptoms of a panic attack develop abruptly and usually reach their peak within 10 min. Most panic attacks end within 20 to 30 min, and they rarely last more than an hour. The client was diagnosed, Panic Anxiety with Agoraphobia. Cognitive behaviour therapy was used for the treatment. After seven sessions, client's symptoms were diminished.

Abstract
BACKGROUND Intimate partner violence puts the victim at risk for substantial medical and psychiatric morbidity. As with other stress- and trauma-related experiences, intimate partner violence is associated with sleep disturbance, particularly insomnia and nightmares. This association, however, has not been well characterized in terms of general prevalence or its further relationship with depression, suicidality, and posttraumatic stress disorder (PTSD). METHODS The present study used validated instruments to characterize insomnia and nightmares among 121 women exposed to intimate partner violence. Participants with and without depression were compared on demographic, abuse, and sleep characteristics as were those with and without suicidality. Logistic regression models were constructed to test sleep variables as independent predictors of depression controlling for demographic factors, abuse severity, and PTSD severity. RESULTS Clinically significant insomnia and nightmares were observed in 46% and 32% of participants, respectively. Depressed women had more severe PTSD and were more likely to have insomnia and to have nightmares than nondepressed women. In models controlling for PTSD severity, the presence of insomnia was associated with an approximately eightfold greater risk of being depressed; nightmares were associated with a twofold increase in risk. CONCLUSIONS Sleep disturbances were prevalent among women experiencing intimate partner violence, with both insomnia and nightmares predicting the presence of depression even after controlling for PTSD severity. In addition to the need to address common mental health issues such as depression, given that sleep problems are modifiable and potentially less stigmatizing than mental health problems, assessing and addressing insomnia and nightmares in survivors of interpersonal violence warrants strong clinical consideration and further investigation.

Abstract
Skin conductance, physical activity, ambient temperature and mood were recorded for 24 h in 22 panic disorder (PD) patients and 29 healthy controls. During the day, subjects performed standardized relaxation tests (ARTs). We hypothesized that tonically elevated anticipatory anxiety in PD during waking and sleeping would appear as elevated skin conductance level (SCL) and greater skin conductance (SC) variability. Mean SCL was higher during both usual waking activities and sleeping in PD, but not during the ARTs. Group SC variability differences did not reach significance, perhaps because of variance unrelated to anxiety. Analyses indicated that in the PD group, antidepressant medication reduced mean SCL whereas state anxiety had the opposite effect during the day. Depressive symptoms reported during the day were related to elevated mean SCL on the night of the recording. The rate and extent of SCL deactivation over the night was equal in the two groups. However, PD patients had more frequent interruptions of deactivation that could have arisen from conditioned arousal in response to threat cues during sleep.

Abstract
Epilepsy and sleep disorders are considered by many to be common bedfellows. Several sleep phenomena may occur during nighttime taking a wide variety of forms and which can mimic seizures. Although most seizure sub-types have the potential to occur during sleep or wakefulness, sleep has a well-documented and strong association with specific epilepsy syndromes. Seizures in sleep also tend to occur during lighter stages of non-REM (NREM) sleep. The neurophysiologic process involved in the deepening of NREM sleep may also facilitate both seizures and IEDs. Epilepsy per se and/or seizures themselves promote sleep disruption and significantly affect the quality, quantity, and architecture of sleep. There are many causes of sleep disruption in patients with epilepsy, including inadequate sleep hygiene, coexisting sleep disorders, and circadian rhythm disturbances. Seizures themselves can disrupt sleep, even when they occur during wakefulness. Anti-epileptic drugs (AEDs) can also alter sleep in positive and negative ways, and these effects are independent of anticonvulsant actions. The end result of sleep disruption is excessive daytime sleepiness, worsening seizures, and poor quality of life. Screening for sleep disorders in the epilepsy population and appropriate intervention strategies will lead to overall improved quality of life and seizure control.

Abstract
Causes of nocturnal paroxysmal events include a variety of disorders such as epileptic seizures, parasomnias, sleep-related movement disorders, and psychiatric disturbances. Timing and semiology of the events, simultaneous video-electroencephalographic observation, presence of any daytime events, and relevant psychiatric and medical history may help in sorting out various possibilities considered in the differential diagnosis of such events. Timely diagnosis of these events is crucial for appropriate management; under-recognition and misdiagnosis of nonepileptic events is not uncommon. Described here are two cases within the spectrum of nocturnal paroxysmal events, one with nocturnal panic attacks and the other with frontal lobe epilepsy, each presenting with choking episodes.

Abstract
Although the precise function of sleep is unknown, decades of research strongly implicate that sleep has a vital role in central nervous system (CNS) restoration, memory consolidation, and affect regulation. Slow-wave sleep (SWS) and rapid eye movement (REM) sleep have been of significant interest to psychiatrists; SWS because of its putative role in CNS energy recuperation and cognitive function, and REM sleep because of its suggested involvement in memory, mood regulation, and possible emotional adaptation. With the advent of the polysomnogram, researchers are now beginning to understand some of the consequences of disrupted sleep and sleep deprivation in psychiatric disorders. The same neurochemistry that controls the sleep-wake cycle has also been implicated in the pathophysiology of numerous psychiatric disorders. Thus it is no surprise that several psychiatric disorders have prominent sleep symptoms. This review will summarize normal sleep architecture, and then examine sleep abnormalities and comorbid sleep disorders seen in schizophrenia, as well as anxiety, cognitive, and substance abuse disorders.

Abstract
Sleep disturbance is increasingly recognized as an important, but understudied, mechanism in the complex and multi-factorial causation of the symptoms and functional disability associated with psychiatric disorders. This review proposes that it is biologically plausible for sleep disturbance to be mechanistically transdiagnostic. More specifically, we propose that sleep disturbance is aetiologically linked to various forms of psychopathology through: its reciprocal relationship with emotion regulation and its shared/interacting neurobiological substrates in (a) genetics--genes known to be important in the generation and regulation of circadian rhythms have been linked to a range of disorders and (b) dopaminergic and serotonergic function--we review evidence for the interplay between these systems and sleep/circadian biology. The clinical implications include potentially powerful and inexpensive interventions including interventions targeting light exposure, dark exposure, the regulation of social rhythms and the reduction of anxiety. We also consider the possibility of developing a 'transdiagnostic' treatment; one treatment that would reduce sleep disturbance across psychiatric disorders.

Abstract
BACKGROUND Panic disorder is a heterogeneous disorder, comprising a variety of somatic, physiological, and cognitive symptoms during repeated panic attacks. As a result, considerable data have examined whether panic attacks may be classified into distinct diagnostic or functional subtypes. The aim of this study is to evaluate the existing literature regarding the validity of panic attack subtypes. METHODS This review focuses on data published since 2000, with the publication of DSM-IV-TR, augmented by replicated data published since 1980, with the publication of DSM-III and subsequently DSM-IV. Published reports evaluating empirical evidence for the validity of panic attack subtypes are reviewed. RESULTS Five sets of panic symptoms (respiratory, nocturnal, nonfearful, cognitive, and vestibular) have been shown to cluster together at varying degrees of consistency. However, none of these potential subtypes have been associated with sufficient and reliable external validation criteria indicative of functional differences. This apparent lack of findings may be related to methodological inconsistencies or limitations across the reviewed studies. CONCLUSIONS Although at present the data do not warrant the utility of subtyping, further research aimed at patent gaps in the literature, including clearer operationalization of symptom subtypes, greater use of biological challenge paradigms and physiological and other more objective measures of fear and anxiety, and exploration of subtyping based on biological factors such as genetics, may support the future designation of panic attack subtypes and their ultimate clinical utility.

Abstract
Nightmares, distressing dreams that primarily arise from REM sleep, are prevalent among the general population and even more so among clinical populations. The frequency of nightmares and related nightmare distress are linked to both sleep disturbance and waking psychopathology. Based on the extant evidence, nightmares appear to be particularly relevant to posttraumatic stress disorder, and may even be implicated in its pathophysiology. Significant advances in treatment have occurred in recent years, with effective pharmacological and psychosocial interventions now available. Despite the progress that has been made, however, more consistent assessment methods and more rigorous study designs are needed to fully understand the causes and consequences of nightmares.

Abstract
Insomnia frequently occurs with trauma exposure and depression, but can ameliorate with improvements in depression. Insomnia was assessed by the insomnia subscale of the Hamilton Rating Scale for Depression in 106 women with childhood sexual abuse (CSA) and major depression receiving interpersonal psychotherapy (IPT) in an uncontrolled pilot (n = 36) and an immediately subsequent randomized controlled trial (n = 70) comparing IPT to treatment as usual. Depression improved in each study and in both treatment conditions; insomnia had smaller, nonsignificant improvements. Overall, 95 women (90%) endorsed insomnia on the Structured Clinical Interview for DSM-IV at baseline and, of those, 90% endorsed insomnia following treatment. Despite improvements in depression, insomnia persists for most women with CSA.

Abstract
OBJECTIVE The aim of this study was to investigate the impact of anxiety disorders and migraine on sleep quality and to find the independent factors that predict sleep quality among patients with major depressive disorder (MDD). METHOD Psychiatric outpatients diagnosed with MDD were enrolled in the study. Major depressive disorder and 7 anxiety disorders were diagnosed using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision. Migraine was diagnosed based on the International Classification of Headache Disorders, Second Edition. Headache intensity and frequency were reported by the subjects. The Pittsburgh Sleep Quality Index and Hamilton Depression Rating Scale were used to evaluate quality of sleep and depression severity, respectively. Multiple linear regressions were used to identify independent factors related to sleep quality. RESULTS One hundred thirty-five subjects (34 men and 101 women) with MDD were enrolled in the study. Subjects with panic disorder and agoraphobia were found to have poorer Pittsburgh Sleep Quality Index scores. Subjects with panic disorder, agoraphobia, and migraine had higher scores for items relating to sleep quality in the Hamilton Depression Rating Scale. Headache intensity and frequency correlated with sleep disturbance. Panic disorder was independently predictive of poor sleep quality. Both migraine and panic disorder independently predicted a greater severity of depression. CONCLUSION Our study demonstrates the negative impact of panic disorder and migraine on MDD and some of the interrelations between depression, anxiety, and sleep quality. Future studies should further explore these interactions and consider possible therapeutic interventions.

Abstract
Anxiety disorders usually are chronic or recurrent disorders characterized by stress sensitivity and a fluctuating course. Both psychopharmacologic and cognitive-behavioral treatments are well-established, evidence-based treatments for panic disorder, social anxiety disorder, generalized anxiety disorder, and obsessive-compulsive disorder. Exposure-based behavioral treatment is well established as evidence-based treatment for specific phobias. Primary care physicians can make a significant impact on patients' lives by identifying and educating about anxiety disorders, directing patients to appropriate self-help resources, choosing evidence-based drug treatment when indicated, and making referrals for specialist care.
