The lifetime impact of attention deficit hyperactivity disorder: results from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC).

BACKGROUND: The aim of the study was to present nationally representative data on the lifetime independent association between attention deficit hyperactivity disorder (ADHD) and psychiatric co-morbidity, correlates, quality of life and treatment seeking in the USA. METHOD: Data were derived from a large national sample of the US population. Face-to-face surveys of more than 34 000 adults aged 18 years and older residing in households were conducted during the 2004-2005 period. Diagnoses of ADHD, Axis I and II disorders were based on the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DSM-IV version. RESULTS: ADHD was associated independently of the effects of other psychiatric co-morbidity with increased risk of bipolar disorder, generalized anxiety disorder, post-traumatic stress disorder, specific phobia, and narcissistic, histrionic, borderline, antisocial and schizotypal personality disorders. A lifetime history of ADHD was also associated with increased risk of engaging in behaviors reflecting lack of planning and deficient inhibitory control, with high rates of adverse events, lower perceived health, social support and higher perceived stress. Fewer than half of individuals with ADHD had ever sought treatment, and about one-quarter had ever received medication. The average age of first treatment contact was 18.40 years. CONCLUSIONS: ADHD is common and associated with a broad range of psychiatric disorders, impulsive behaviors, greater number of traumas, lower quality of life, perceived social support and social functioning, even after adjusting for additional co-morbidity. When treatment is sought, it is often in late adolescence or early adulthood, suggesting the need to improve diagnosis and treatment of ADHD.

Low-frequency rTMS over right dorsolateral prefrontal cortex in the treatment of resistant depression: cognitive improvement is independent from clinical response, resting motor threshold is related to clinical response.

BACKGROUND: Clinical studies have shown that repetitive transcranial magnetic stimulation (rTMS) is effective in a certain percentage of treatment-resistant depression (TRD). The left dorsolateral prefrontal cortex (DLPFC) 10 Hz rTMS stimulation received FDA approval in 2008, although different rTMS protocols have also shown their effectiveness in reducing depressive symptoms. We investigated the clinical, cognitive and neurophysiologic effects of a 3 weeks' protocol of low-frequency rTMS applied over the right DLPFC in resistant depression. METHODS: Twenty-eight patients with TRD (age range 28-55) received low-frequency rTMS (1 Hz) over the right DLPFC in a 3-week open trial. Hamilton scales for depression and anxiety, Corsi block-tapping test, phonemic verbal fluency, right and left resting motor thresholds were evaluated in each subject over the trial period. RESULTS: At the end of the trial 42.9% of the subjects were considered as responders. A significant reduction of both HAMD (p < 0.001) and HAMA (p < 0.01) total scores was observed. At the 3rd week, the performances in Corsi test (p < 0.02) and phonemic verbal fluency (p = 0.065) were improved independently from depressive symptoms variation. At the end of the rTMS protocol, a significantly decreased left hemisphere resting motor threshold was registered (p < 0.01), while right hemisphere resting motor threshold did not show significant variation. CONCLUSION: Low-frequency rTMS over the right DLPFC appeared effective in 42.9% of depressive resistant subjects in this sample. A significant decrease in left hemisphere resting motor threshold was observed only in responders, while a trend for improvement in cognitive function has been found and appeared independent from clinical response.

Autoimmune markers in vitiligo patients appear correlated with obsession and phobia.

BACKGROUND: Current studies have treated a limited portion of the subjective aspects of vitiligo patients and have yet to elucidate possible psychological differences between those with autoimmune markers (AIM) with respect to those without autoimmune markers (NAIM). OBJECTIVE: To perform an age and gender-matched 1:1 case-control study through a comparison of non-segmental vitiligo patients with autoimmune features vs. those without autoimmune features in regards to psychiatric features, psychosomatic aspects and social parameters. METHODS: A total of 112 non-segmental vitiligo patients have been examined at the Florence University dermatology outpatient service (2nd dermatology unit). Vitiligo with an autoimmune background was defined by the presence of autoimmune antibodies and/or autoimmune diseases. Psychiatric screening was performed by dermatologists using the modified Middlesex Healthcare Questionnaire (MHQ); psychosomatic aspects and social impact were analysed with a standardized, Florentine questionnaire. RESULTS: Upon performing a conditional regression model, age, phobia and obsession were significantly predictive of the presence of AIM and a low total MHQ score was significantly predictive of NAIM in vitiligo patients. With univariate analysis, we found significant differences in: identifiable stress related to the onset of vitiligo, vitiligo triggered by stress, and modified interpersonal relationships related to vitiligo, which were associated with the subgroup containing autoimmunity markers. CONCLUSIONS: We found a higher prevalence of age, obsession and phobia among vitiligo patients AIM as compared to vitiligo patients NAIM. Thus, in the presence of demonstrated autoimmunity, screening for particular psychiatric aspects may be useful in the clinical practice of vitiligo.

Major depression and bipolar disorders in CADASIL: a study using the DSM-IV semi-structured interview.

OBJECTIVE: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebral microangiopathy characterized by migraine, cerebrovascular events, and cognitive impairment. Although recognized as a cardinal feature of the disease, psychiatric disturbances have rarely been the object of focused studies. We performed a structured evaluation of mood disorders in CADASIL. MATERIALS AND METHODS: Twenty-three patients with CADASIL (five men and 18 women) were assessed by psychiatrists using the Structured Clinical Interview for the DSM-IV, clinician version. For the quantitative assessment of current mood disorder symptoms, the Hamilton Rating Scale for Depression (HRSD) and the Young Mania Rating Scale (YMRS) were used. RESULTS: A lifetime depressive episode was recorded in 17/23 (73.9%) patients with CADASIL. Six (26.1%) patients with CADASIL reported a current depressive episode. A diagnosis of manic lifetime episode was made in 6 (26.1%) patients with CADASIL. The HRSD mean score in patients with current depression was 9.1 ± SD 8.1. The YMRS mean score was 14.2 ± SD 4.1 for manic CADASIL. CONCLUSION: This study confirms that mood disorders are frequent in CADASIL. The use of a structured psychiatric interview outlines a frequency of depression higher than that previously reported but also reveals a considerable frequency of bipolar disorders. If confirmed in larger series, these data suggest that a greater attention should be paid to the psychiatric aspects in CADASIL.

Detecting attention-deficit/hyperactivity disorder (ADHD) in adults with intellectual disability The use of Conners' Adult ADHD Rating Scales (CAARS).

There is an increasing interest in the diagnosis of attention-deficit/hyperactivity disorder (ADHD) in adulthood. It is also thought that ADHD is more prevalent in the field of intellectual disability (ID) than in the general population, but there are not many experimental studies. Since ADHD diagnosis in adults is more difficult, specific rating scales correlated to the main diagnostic systems have been created but have not been applied to people with ID. This work presents an application of an ADHD screening rating scale, the Conners' Adult ADHD Rating Scales (CAARS) screening version to 46 adults with ID. The resulting prevalence of "ADHD-positive" was 19.6%. These data are in accord with results reported in the general adult literature. Our data suggest that ID and attention disorders can co-occur. Therefore, not only can ADHD be a valid psychiatric diagnosis for a child with ID but for an adult with ID as well. The CAARS can be considered a useful clinical instrument to survey ADHD in ID.

Manifesto for a European research network into Problematic Usage of the Internet.

The Internet is now all-pervasive across much of the globe. While it has positive uses (e.g. prompt access to information, rapid news dissemination), many individuals develop Problematic Use of the Internet (PUI), an umbrella term incorporating a range of repetitive impairing behaviours. The Internet can act as a conduit for, and may contribute to, functionally impairing behaviours including excessive and compulsive video gaming, compulsive sexual behaviour, buying, gambling, streaming or social networks use. There is growing public and National health authority concern about the health and societal costs of PUI across the lifespan. Gaming Disorder is being considered for inclusion as a mental disorder in diagnostic classification systems, and was listed in the ICD-11 version released for consideration by Member States (http://www.who.int/classifications/icd/revision/timeline/en/). More research is needed into disorder definitions, validation of clinical tools, prevalence, clinical parameters, brain-based biology, socio-health-economic impact, and empirically validated intervention and policy approaches. Potential cultural differences in the magnitudes and natures of types and patterns of PUI need to be better understood, to inform optimal health policy and service development. To this end, the EU under Horizon 2020 has launched a new four-year European Cooperation in Science and Technology (COST) Action Programme (CA 16207), bringing together scientists and clinicians from across the fields of impulsive, compulsive, and addictive disorders, to advance networked interdisciplinary research into PUI across Europe and beyond, ultimately seeking to inform regulatory policies and clinical practice. This paper describes nine critical and achievable research priorities identified by the Network, needed in order to advance understanding of PUI, with a view towards identifying vulnerable individuals for early intervention. The network shall enable collaborative research networks, shared multinational databases, multicentre studies and joint publications.

Obsessive-compulsive disorder in the elderly: A report from the International College of Obsessive-Compulsive Spectrum Disorders (ICOCS).

INTRODUCTION: Obsessive-compulsive disorder (OCD) is a highly disabling condition, with frequent early onset. Adult/adolescent OCD has been extensively investigated, but little is known about prevalence and clinical characterization of geriatric patients with OCD (G-OCD≥65years). The present study aimed to assess prevalence of G-OCD and associated socio-demographic and clinical correlates in a large international sample. METHODS: Data from 416 outpatients, participating in the ICOCS network, were assessed and categorized into 2 groups, age

MDMA (Ecstasy) precipitation of panic disorder.

The authors describe three patients whose panic disorder began during recreational use of MDMA (Ecstasy) and was subsequently complicated by agoraphobic avoidance that continued autonomously after cessation of the drug. Their panic disorder responded well to serotoninergic antidepressant drugs. Theoretical and practical implications are discussed.

Intravenous clomipramine challenge in obsessive-compulsive disorder: predicting response to oral therapy at eight weeks.

BACKGROUND: Challenge with intravenous clomipramine (CMI) is serotonin selective and has been reported to transiently exacerbate symptoms in obsessive-compulsive disorder (OCD) patients, and to predict subsequent response to oral CMI therapy. METHODS: We administered CMI (12.5 mg, i.v.) to medication free OCD patients (N = 29) and normal controls (N = 22) to characterize neurohormonal response. A subset of OCD patients (26/29), was then treated with either pulse load i.v. or oral CMI followed by 8 weeks of oral CMI therapy. RESULTS: In response to CMI challenge, OCD patients exhibit blunted cortisol and exaggerated growth hormone response relative to normal controls. OCD patients differ from controls in "sadness" ratings, with control exhibiting increased dysphoria in response to CMI. Growth hormone response to CMI challenge predicts treatment response (> or = 25% decreases YBOCS from baseline) to oral CMI at 8 weeks. CONCLUSIONS: Growth hormone abnormalities associated with OCD in response to CMI challenge differentiates nonresponders after 8 weeks of oral CMI treatment from responders.

Smooth-pursuit eye movement and saccadic intrusions in obsessive-compulsive disorder.

Although several reports agree that smooth-pursuit eye movement (SPEM) is abnormal in some obsessive-compulsive disordered (OCD) patients, differences between treatments and lack of accuracy in control selection make the results controversial. Although reduced gain seems the most accepted abnormality, the characteristics of saccadic disruption of smooth pursuit are as yet unspecified. SPEMs in 21 OCD patients (DSM-III-R) and 21 healthy subjects recruited from the community were studied through a multiple target velocity task . The two groups were individually matched on age, gender, and level of education. None of the subjects had a history of substance dependence apart from the smokers who refrained from smoking in the 2 hours prior to the test. A significantly lower SPEM gain and increased number and frequency of anticipatory saccades (ASs) was found in OCD patients as compared with control subjects. No relationship emerged between eye movement abnormalities and clinical variables explored.

Recent life events and panic disorder.

The authors assessed life events during the 12 months before the onset of panic disorder in 64 patients. Compared with a control group of 78 healthy subjects, patients with panic disorder had higher scores however life events were assessed, i.e., number of events, weighted normative scores, contextual scores, and number of subjects with major events. Independent life events (those beyond the subject's control) were also more numerous and more severe among the patients. The larger number of events experienced by the patients was due to the more frequent occurrence of life stress in the month before the onset of panic disorder. Loss events had the strongest relationship to panic disorder.

Relapse in young paranoid schizophrenic patients: a prospective study of stressful life events, P300 measures, and coping.

OBJECTIVE: The authors investigated the relationship of cognitive and coping characteristics to stressful life events at the time of relapse in patients with recent-onset paranoid schizophrenia. METHOD: Over 6 years, the authors collected data on 41 schizophrenic outpatients aged 18-28 years at recruitment. The patients were rated prospectively every 2 weeks with the Brief Psychiatric Rating Scale, Scale for the Assessment of Negative Symptoms, Scale for the Assessment of Positive Symptoms, Global Assessment of Functioning Scale, and life events measures. The Frankfurt Questionnaire of Complaints was used to analyze subjective complaints regarding cognitive and coping abilities. The P300 auditory event-related potential was measured at recruitment to provide an index of information-processing capability. RESULTS: Patients without severe life events during the 1 month before relapse had a smaller P300, more subjective complaints, and less coping capacity than did relapsed schizophrenic subjects who had severe life events in the month before relapse. CONCLUSIONS: Relapses in subjects without severe life events were associated with fewer cognitive resources and less coping ability. Patients with normal P300 and adequate coping resources seemed to be able to deal better with stressful life events.

Rapid benefit of intravenous pulse loading of clomipramine in obsessive-compulsive disorder.

OBJECTIVE: The authors conducted a randomized, double-blind, placebo-controlled trial of intravenous versus oral pulse loading of clomipramine in patients with obsessive-compulsive disorder to test two hypotheses: 1) intravenous pulse loading will cause greater immediate improvement than oral pulse loading and 2) patients who respond to pulse loading will continue to improve during 8 weeks of oral clomipramine treatment. METHOD: Fifteen patients with DSM-III-R obsessive-compulsive disorder of at least 1 year's duration and baseline Yale-Brown Obsessive Compulsive Scale scores of 17 or higher were enrolled in the study. Yale-Brown scale ratings were made 4.5 days after double-blind oral or intravenous pulse loading of clomipramine, and patients were then given 150 mg/day of oral clomipramine with increases of 25 mg every 4 days to 250 mg/day as tolerated or, in two cases, other selective serotonin reuptake inhibitors (SSRIs). RESULTS: The first hypothesis was confirmed: 4.5 days after the second pulse-loaded dose, six of seven patients given intravenous clomipramine but only one of eight given oral medication responded to the drug. After 8 weeks of oral clomipramine, the results partially supported the second hypothesis: four of six patients who had responded to intravenous clomipramine continued their improvement, but those who had responded to pulse loading did not improve statistically significantly more than those who had not. CONCLUSIONS: Intravenous pulse loading of clomipramine may be a valuable new treatment for obsessive-compulsive disorder, particularly for patients who have failed oral treatment trials.

Depressive relapses and incomplete recovery from index episode.

Of 101 patients suffering from primary unipolar depression who were followed up for at least 1 year after recovery from the index episode, 51 relapsed into a new depressive episode within the year of recovery. Only those variables related to the period immediately after discharge distinguished nonrelapsers from relapsers; relapsers showed higher levels of residual symptoms, inferior social adaptation, a more pathological mean personality profile, and lower tricyclic plasma levels, despite similar dosage. The data are consistent with the hypothesis of an incomplete recovery from the index episode as a risk factor for relapse within 1 year.

Onset of panic disorder.

The situations in which the first panic attack occurred were investigated in 44 patients affected by panic disorder. Although the first panic attack was reported to be unexpected and no avoidance was present before it, 75.8% of patients (N = 22) with panic disorder with agoraphobia had their first panic attack in phobogenic situations, compared with 20% of patients (N = 3) with panic disorder without agoraphobia.

Awareness of illness and subjective experience of cognitive complaints in patients with bipolar I and bipolar II disorder.

OBJECTIVE: The authors' goal was to investigate the awareness of illness and subjective cognitive complaints of patients with either bipolar I disorder or bipolar II disorder during a phase of clinical stabilization. METHOD: They used a structured clinical interview, the Frankfurt Complaints Questionnaire, to determine subjective cognitive complaints, and the Scale of Unawareness of Mental Disorder to assess 57 consecutively enrolled patients with bipolar I or bipolar II disorder. RESULTS: Patients with bipolar II disorder had significantly less insight and a higher level of subjective complaints of stimulus overload than patients with bipolar I disorder. CONCLUSIONS: These results suggest that a severe deficit in self-awareness may constitute a distinguishing psychopathological characteristic of patients with bipolar II disorder. Further studies are required to determine if there are associated neuropsychological dysfunctions.

Emotional arousal and phobia in transient global amnesia.

OBJECTIVE: To evaluate the role of emotionally stressful or phobogenic events and phobic personality traits in transient global amnesia (TGA). DESIGN: Case-control study. SETTING: Tertiary care center. PATIENTS: Fifty-one case patients with TGA (mean +/- SD age, 62.7 +/- 6.7 years) compared with 51 control patients with transient ischemic attacks (mean +/- SD age, 63.8 +/- 6.7 years). MAIN OUTCOME MEASURES: Precipitant factors, life events, and phobic attitudes. RESULTS: Of the 25 TGA attacks that were triggered by a precipitant, 11 were possibly related to emotionally stressful or phobogenic situations. On a scale that measured phobic attitudes, the case patients with TGA scored significantly higher than the control patients with transient ischemic attacks (mean +/- SD total score, 15.21 +/- 11.0 vs 4.41 +/- 5.2; P < .001 by corrected analysis of variance for age, sex, and education). The amount of stressful live events in the year that preceded the attack did not differ between the case patients with TGA and the control patients with transient ischemic attacks. CONCLUSION: The results support the hypothesis that emotional arousal and phobia are involved in TGA.

The emergence of social phobia during clozapine treatment and its response to fluoxetine augmentation.

BACKGROUND: The underlying neurochemical basis of social phobia has yet to be fully explained, but there are suggestions of serotonergic and dopaminergic dysfunction. The atypical neuroleptic clozapine has been reported to induce anxiety symptoms, probably owing to its effect on serotonergic pathways. We report 12 cases of schizophrenic patients who developed social phobia during clozapine treatment. METHOD: Patients were assessed using the Structured Clinical Interview for DSM-III-R, Patient Version, Scale for the Assessment of Negative Symptoms, Scale for the Assessment of Positive Symptoms, the Liebowitz Social Phobia Scale, and the Brief Psychiatric Rating Scale. They were reevaluated after 12 weeks of cotreatment with clozapine and fluoxetine. RESULTS: In 8 of the 12 cases, symptoms responded (> or = 35% reduction in Liebowitz Social Phobia Scale score) with an adjunctive regimen of fluoxetine. CONCLUSION: Data are discussed in light of neurochemical mechanisms and cognitive adaptations that could explain the onset of anxiety spectrum disorders (such as social phobia) in clozapine-treated schizophrenic subjects during remission of psychotic symptoms.
