Given the increasing number of college students seeking Attention-Deficit/Hyperactivity Disorder (ADHD) diagnoses as well as the potential secondary gains associated with this disorder (e.g., access to stimulant medication, academic accommodations), the detection of malingered symptom presentations in this population is a major concern. The present study examined the ability of validity indicators on the widely used Personality Assessment Inventory (PAI; Morey, 1991) to distinguish between individuals experiencing genuine ADHD symptoms and individuals instructed to present with ADHD symptomatology for secondary gain...

Premenstrual dysphoric disorder (PMDD) remains a controversial diagnosis: Some authors have argued that it pathologizes normal mood changes, and others have questioned the need for daily mood reports across multiple cycles. In the present study, we examined changes in mood among psychologically healthy young participants with regular menstrual cycles. We collected daily reports of negative mood (depression, nervousness, irritability, and fatigue) across two to six consecutive cycles from 27 participants aged 18-35 years, and we used variance decomposition analyses to examine how much of the variance in these daily reports was due to day, cycle, and individual...

Background: The role of psychosocial factors has been established in patients with shoulder abnormalities. However, the prevalence of exaggerated pain behaviors and their association with the characteristics of injured workers have not been well studied. Purpose: To examine the prevalence of abnormal pain responses (APRs) in workers with active workers' compensation claims for a shoulder injury and to examine the differences between workers with APRs versus workers without APRs...

Infants with Sandhoff disease typically appear normal until 3-6 months of age. As the disease progresses, they present with symptoms such as loss of motor skills, exaggerated startle response to loud noise, seizures, visual loss, and paralysis. We encountered a rare case of a 22-month-old girl with Sandhoff disease characterized by progressive motor weakness and dysphagia, who initially showed signs of aspiration at 20 months of age. The major problems related to dysphagia were oromotor dysfunction and abnormal feeding posture...

Amyotrophic lateral sclerosis is a motoneuron degenerative disease that is challenging to diagnose and presents with considerable variability in survival. Early identification and enhanced understanding of symptomatic patterns could aid in diagnosis and provide an avenue for monitoring disease progression. Use of the mSOD1G93A mouse model provides control of the confounding environmental factors and genetic heterogeneity seen in amyotrophic lateral sclerosis patients, while investigating underlying disease-induced changes...

Naveen K Bhatraju, Anurag Agrawal
The bidirectional epidemiological association between asthma and obesity is well known. Recent evidence suggests that there is an intersection of the pathophysiological molecular pathways leading to either obesity or asthma, at the level of mitochondria. This is not surprising, because mitochondria, beyond their roles as the metabolic powerhouses of the cell, serve as sensors of threats, regulators of stress signaling, and effectors of cytotoxicity. Reduced mitochondrial function and low metabolic activity are well-recognized features of obesity...

Since its initial description in 1851, Munchausen syndrome has been widely used interchangeably with factitious disorder. Nevertheless, this syndrome is only one form of factitious disorder that is both severe and chronic. The syndrome was named after Karl Friedrich Hieronymus, Baron von Münchhausen (1720-1797), a German nobleman who became famous as a narrator of false and exaggerated exploits. His name was progressively corrupted to Munchausen. Factitious disorders and Munchausen syndrome remain a great diagnosis challenge for physicians...

OBJECTIVES: Only a minority of patients referred to specialists with sinonasal symptoms have clear evidence of chronic rhinosinusitis. This study aims to estimate the prevalence of and associations between (i) general illness factors (fatigue, autonomic dysfunction) and (ii) psychological factors (anxiety, depression, somatisation, personality traits) in patients presenting with sinonasal symptoms. DESIGN: The following validated questionnaires were administered to patients: the Sino-Nasal Outcome Test-22 (SNOT-22) to identify symptom burden, Composite Autonomic Symptom Score-31 (COMPASS-31) measuring autonomic function, Chalder fatigue questionnaire, Patient Health Questionnaire-15 (PHQ-15) addressing somatisation symptoms, Hospital Anxiety and Depression Scale (HADS), and the International Personality Item Pool-50 (IPIP-50)...

OBJECTIVES: Altered social behavior during mood episodes in bipolar disorder often has detrimental and long-lasting interpersonal consequences. Abnormal face processing may play a role in linking brain functions to clinical symptoms and behavior. This study aimed to understand configural face processing in bipolar disorder as a function of basic communicative attributes of the face and mood symptoms using event-related brain potentials (ERPs). METHODS: Forty-two participants with bipolar I disorder (BP) and 43 healthy controls (HC) viewed face stimuli varying in emotion (neutral or fearful), head orientation (forward or deviated), and gaze direction (direct or averted) while ERPs were recorded...

Post-traumatic stress disorder (PTSD) is predominant amongst individuals addicted to opioids and obscures the course of illness and the treatment outcome. We report the case of a patient with major depressive disorder and opioid dependence, who experienced post-traumatic stress disorder symptoms during a recent visit to the inpatient unit. The similarity of symptoms between post-traumatic stress disorder and opioid dependence is so high that, sometimes, it is a challenge to differentiate between these conditions...

Assessing symptom validity is essential both in the clinical and medicolegal contexts. If neurological symptoms are demonstrated and/or a patient complains of pain that is not or cannot be fully explained by an underlying disease, it is necessary to recognize reliably a possible psychological cause in order to avoid further unnecessary examinations. In the medicolegal context, malingering or exaggeration of complaints for obtaining financial benefit is to be differentiated in a further step. The present overview contains a summary of clinical observations and tests for neurologists and psychiatrists used for symptom validity assessment of sensorimotor symptoms, tremor, gait, equilibrium and visual disturbances as well as pain...

BACKGROUND: The vast majority of research on mental health has been undertaken in high income countries. This study aimed at investigating the long-term course of maternal depressive symptoms and its association with various mother- and child-related characteristics in two West African lower middle income countries with focus on the relationship with long-term anxiety symptoms. METHODS: In the Child Development Study, a prospective birth cohort study in Côte d'Ivoire and Ghana, the 9-item Patient Health Questionnaire (PHQ-9) was answered by N = 776 women 3 months antepartum, and 3, 12, and 24 months postpartum between April 2010 and March 2014...

Major depression disorder (MDD) and anxiety disorder are both prevalent and debilitating. High rates of comorbidity between MDD and social anxiety disorder (SAD) suggest common pathological pathways, including aberrant neural processing of interpersonal signals. In patient populations, the determination of common and distinct neurofunctional markers of MDD and SAD is often hampered by confounding factors, such as generally elevated anxiety levels and disorder-specific brain structural alterations. This study employed a dimensional disorder approach to map neurofunctional markers associated with levels of depression and social anxiety symptoms in a cohort of 91 healthy subjects using an emotional face processing paradigm...

BACKGROUND: De novo mutations in PURA have recently been described to cause PURA syndrome, a neurodevelopmental disorder characterised by severe intellectual disability (ID), epilepsy, feeding difficulties and neonatal hypotonia. OBJECTIVES: To delineate the clinical spectrum of PURA syndrome and study genotype-phenotype correlations. METHODS: Diagnostic or research-based exome or Sanger sequencing was performed in individuals with ID. We systematically collected clinical and mutation data on newly ascertained PURA syndrome individuals, evaluated data of previously reported individuals and performed a computational analysis of photographs...

In 2001, it was observed that the cardia region of the lumen of the stomach remained highly acidic after a meal and escaped the buffering effect of the food. This phenomenon was termed the acid pocket and is thought to explain why reflux symptoms occur after meals despite the buffering effect of food. This review describes the discovery of the acid pocket and our progress in understanding the intragastric physiology producing it, its exaggeration in hiatus hernia and role in reflux disease. The recent discovery that the acid pocket is attenuated in the Helicobacter pylori-infected population and the significance of this to the negative association between H...

The symptom reports of individuals with chronic pain are multidimensional (e.g., emotional, cognitive, and somatic) and significantly contribute to increased morbidity and lost work productivity. When pain occurs in the context of a legally compensable event, reliable assessment of a patient's multifactorial symptom experience during psychological or neuropsychological evaluations is a necessity. The Validity Scales of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2) have been shown useful in identifying symptom overreporting and feigning within chronic pain samples and a number of studies have emerged supporting the use of the MMPI-2-Restructured Form (MMPI-2-RF) in the detection of simulated or feigned impairment in a variety of populations...

The genetic trait of lactase persistence (LP) is associated with at least five independent functional single nucleotide variants in a regulatory region about 14 kb upstream of the lactase gene [-13910*T (rs4988235), -13907*G (rs41525747), -13915*G (rs41380347), -14009*G (rs869051967) and -14010*C (rs145946881)]. These alleles have been inferred to have spread recently and present-day frequencies have been attributed to positive selection for the ability of adult humans to digest lactose without risk of symptoms of lactose intolerance...

Symptom validity tests (SVTs) are predicated on the assumption that overendorsement of atypical symptoms flags symptom exaggeration (i.e., questionable symptom validity). However, few studies have explored how practitioners from different cultural backgrounds evaluate such symptoms. We asked professionals working in Western (n = 56) and non-Western countries (n = 37) to rate the plausibility of uncommon symptoms taken from the Structured Inventory of Malingered Symptomatology (SIMS), dissociative symptoms from the Dissociative Experience Scale (DES-T), and standard symptoms (e...

Exaggerated basal ganglia beta activity (13-35 Hz) is commonly found in patients with Parkinson's disease and can be suppressed by dopaminergic medication, with the degree of suppression being correlated with the improvement in motor symptoms. Importantly, beta activity is not continuously elevated, but fluctuates to give beta bursts. The percentage number of longer beta bursts in a given interval is positively correlated with clinical impairment in Parkinson's disease patients. Here we determine whether the characteristics of beta bursts are dependent on dopaminergic state...

High mobility group protein B1 (HMGB1) is a late inflammatory mediator released from inflammatory cells when stimulated, resulting in exaggerating septic symptoms. We recently demonstrated that full-length adiponectin, a potent anti-inflammatory adipokine, inhibits lipopolysaccharide-induced HMGB1 release. However, the effects of adiponectin on HMGB1-induced exaggerating signals currently remain unknown. This study aimed to investigate the effects of adiponectin on the pro-inflammatory function of HMGB1 in RAW264 macrophage cells...
