INTRODUCTION: Comprehensive understanding of the association between depression and neuropsychological functioning over the course of adolescence requires developmentally sensitive assessment through longitudinal data. The aim of current study is to examine the concurrent and subsequent effects of depressive symptoms on the initial level and evolution of four neuropsychological functioning domains (i.e., spatial working memory, delayed recall memory, perceptual reasoning, and inhibitory control)...

Perceived injustice is a belief that one has been treated unfairly, disrespectfully, and is suffering unnecessarily as a result of another person's actions. Perceived injustice predicts chronic disability after musculoskeletal injury, but to our knowledge, has not been empirically studied in people with mild traumatic brain injuries (MTBIs). We examined perceived injustice and its correlates in patients who were slow to recover from MTBI. Patients (N=102) were recruited from four concussion clinics. The sample was on average 41...

College students without ADHD may feign symptoms of ADHD to gain access to stimulant medications and academic accommodations. Unfortunately, research has shown that it can be difficult to discriminate malingered from genuine ADHD symptomatology, especially when evaluations are based only on self-report questionnaires. The present study investigated whether nonclinical college students given no additional information could feign ADHD as successfully as those who were coached on symptoms of the disorder. Similar to Jasinski et al...

Traditional efforts to delineate the clinical heterogeneity of schizophrenia have been unsuccessful because of the absence of a valid, stable, and meaningful subtyping scheme. A clinically-informed nosology supported by multivariate statistical classification methods may provide a better approach for classifying schizophrenia. The goals of the current study were to 1) use multivariate classification methods to validate a clinical subtyping scheme based on the profile of negative symptoms; and 2) following validation to contrast the statistically-derived subgroups to ascertain distinguishing demographic, clinical, cognitive, and functional characteristics...

OBJECTIVE: Primary psychiatric disorders (PsD) can present with symptomatology identical to that of behavioral variant frontotemporal dementia (bvFTD). To date, clinical guidelines do not provide a solution for this diagnostic challenge. The aim of our study was to prospectively determine which demographic, clinical, neuropsychological, neuroimaging, and cerebrospinal fluid biomarkers are important in distinguishing PsD from bvFTD. METHODS: Patients with late-onset behavioral disturbances (aged 45-75 years, 73% male) were included based on their scores on the Frontal Behavioral Inventory and the Stereotypy Rating Inventory and followed for 2 years from April 2011 to June 2015...

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...

Objective: To examine the influence of different performance validity test (PVT) cutoffs on neuropsychological performance, post-concussion symptoms, and rates of neurocognitive disorder and postconcussional syndrome following mild traumatic brain injury (MTBI) in active duty service members. Method: Participants were 164 service members (Age: M = 28.1 years [SD = 7.3]) evaluated on average 4.1 months (SD = 5.0) following injury. Participants were divided into three mutually exclusive groups using original and alternative cutoff scores on the Test of Memory Malingering (TOMM) and the Effort Index (EI) from the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS): (a) PVT-Pass, n = 85; (b) Alternative PVT-Fail, n = 53; and (c) Original PVT-Fail, n = 26...

IMPORTANCE: Chronic fatigue syndrome (CFS) is characterised by a constellation of symptoms diagnosed with a number of different polythetic criteria. Heterogeneity across these diagnostic criteria is likely to be confounding research into the as-yet-unknown pathophysiology underlying this stigmatised and debilitating condition and may diagnose a disease spectrum with significant implications for clinical management. No studies to date have objectively investigated this possibility using a validated measure of CFS symptoms-the DePaul Symptom Questionnaire (DSQ)...

The current gold standard for diagnosis of attention deficit/hyperactivity disorder (ADHD) includes subjective measures, such as clinical interview, observation, and rating scales. The significant heterogeneity of ADHD symptoms represents a challenge for this assessment and could prevent an accurate diagnosis. The aim of this work was to investigate the ability of a multi-domain profile of measures, including blood fatty acid (FA) profiles, neuropsychological measures, and functional measures from near-infrared spectroscopy (fNIRS), to correctly recognize school-aged children with ADHD...

BACKGROUND: Following stroke, clinicians are challenged to detect and untangle symptoms of cognitive dysfunction and mood disorders. Additionally, they need to evaluate the informative value of self-reports to identify patients in need of further attendance. AIMS: To examine the association between neuropsychological measures, symptoms of depression, and self-reported cognitive function. METHODS: One-hundred and five chronic stroke patients underwent assessment covering 6 cognitive domains and answered the Hospital Anxiety and Depression Scale and the Memory and Thinking Scale from the Stroke Impact Scale 1 year after stroke...

The clinical neuropsychologist has the opportunity to be uniquely involved in the evaluation and treatment of individuals with amyotrophic lateral sclerosis (ALS). We review the current literature that defines cognitive and behavioral symptoms in ALS, including current knowledge of the neuropathological and genetic underpinning for these symptoms. There are unique considerations for clinical neuropsychological evaluation and clinical research in ALS and we highlight these in this review. Specifically, we shed light on special factors that contribute to our understanding of cognitive and behavioral impairment in ALS, including co-morbid symptoms, differential diagnosis, and considerations for longitudinal tracking of phenotypes...

There is a subset of patients with mild traumatic brain injury (mTBI) who report persistent symptoms that impair their functioning and quality of life. Being able to predict which patients will experience prolonged symptom recovery would help clinicians target resources for clinical follow-up to those most in need, and would facilitate research to develop precision medicine treatments for mTBI. The purpose of this study was to investigate the predictors of symptom recovery in a prospective sample of emergency department trauma patients with either mTBI or non-mTBI injuries...

Dementia is a devastating manifestation of Parkinson's disease (PD). This study investigates whether a common polymorphism in the PITX3 gene (rs2281983), which is of importance for the function of dopaminergic neurons, affects the risk of developing dementia in PD and whether it affects dopamine transporter (DAT) uptake. We PITX3 genotyped 133 patients with new-onset, idiopathic PD, participating in a population-based study in Sweden. Patients were followed prospectively during 6-11years with extensive investigations, including neuropsychology and DAT-imaging with (123)I FP-CIT...

Importance: Scientific and lay interest in negative outcomes associated with exposure to repetitive brain trauma (RBT) continues to strengthen. Concerns about the association between RBT and dementia began more than a century ago, but have resurfaced in the last decade with the more recently described chronic traumatic encephalopathy (CTE). Chronic traumatic encephalopathy is a tauopathy associated with RBT that has become inextricably linked to conversations about sport-related concussion and mild traumatic brain injury...

BACKGROUND: Excessive exposure to manganese (Mn) may cause parkinsonian-like motor and tremor symptoms and adverse cognitive effects, including problems with executive functioning (EF), resembling those found in later-stage Parkinson's disease (PD). Studies seeking to differentiate PD patients into subgroups with associated cognitive and functional outcomes using motor and tremor symptoms identified tremor-dominant (TD) and non-tremor dominant (NTD) subtypes. It is unclear whether differing patterns of pathophysiology and symptoms exist in Mn neurotoxicity, as they do in PD...

The multiple causal pathways model on the etiology of attention-deficit/hyperactivity disorder (ADHD) is well established. However, developmental implications of the model are not yet sufficiently analyzed. The model implies that critical neural and neuropsychological deviations from normative development precede secondarily developing ADHD symptoms. Cognitive, "cool" inhibitory control (CIC) and reward-related, "hot" functions (RRF) are regarded as neuropsychological basic deficits that indicate independent causal pathways...

BACKGROUND: Available treatment options for Parkinson's disease (PD) are primarily aimed at pharmacological and/or neurosurgical management of motor symptoms. However, many patients also experience chronic non-motor symptoms (NMS), including significant cognitive and mood changes. Currently, there is a gap in the neuropsychological literature regarding the efficacy of nonpharmacological treatment options for cognitive and mood changes in PD. OBJECTIVE: We sought to evaluate the efficacy and patient satisfaction of a pilot nonpharmacological intervention for alleviating NMS in patients with PD...

BACKGROUND: Mild cognitive impairment in Parkinson's disease (PD-MCI) is a common clinical condition. Understanding its pathology and clinical features is important for early intervention before the onset of dementia. In the past, variable definitions and differences in neuropsychological batteries generated divergent results of the affected cognitive patterns. MAIN BODY: The introduction of PD-MCI criteria by the Movement Disorders Society (MDS) Task Force provides a more uniform system for defining and measuring PD-MCI and may improve the validity of future research...

The expression of cognitive symptoms associated with HIV varies over time and across individuals. This pattern may reflect transient contextual factors, including the degree of effort exerted by individuals undergoing cognitive testing. The present study examined whether effort corresponds to the expression of persistent HIV-related cognitive impairment among individuals receiving combination antiretroviral therapy (cART). HIV+ individuals (n = 111) averaged 48.2 (14.9) years of age and 13.0 (2.7) years of education and HIV- individuals (n = 92) averaged 34...
