Impaired attention and learning functions are common in schizophrenia. The details of this impairment, and how these change across time, are not well known. We aimed to compare the parameters of well-known attention and learning neuropsychological tests in first-episode schizophrenia (FES) patients and healthy controls in a 2-year follow-up period. The performance of 28-25 FES patients and pairwise matched healthy controls on the Continuous Performance Test-Identical Pairs, the revised Hopkins Verbal Learning Test, and the revised Brief Visuospatial Memory Test was compared at baseline and 2 years later...

OBJECTIVE: Older individuals with schizophrenia are at risk of being treated with anticholinergic medications due to the prevalence of medical comorbidities and polypharmacy. High anticholinergic burden impairs cognition and is a risk factor for Alzheimer's dementia. Thus, we assessed the impact of anticholinergic burden on Alzheimer's dementia-related and schizophrenia-related cognitive functions in older patients with schizophrenia. METHODS: Anticholinergic burden was measured using the Anticholinergic Cognitive Burden scale (ACB) in 60 community-dwelling patients aged ≥ 50 years who met DSM-IV criteria for schizophrenia between May 2007 and November 2011...

OBJECTIVES: The Automated Neuropsychological Assessment Metrics 4 TBI-MIL (ANAM4) is a computerized cognitive test often used in post-concussion assessments with U.S. service members (SMs). However, existing evidence remains mixed regarding ANAM4's ability to identify cognitive issues following mild traumatic brain injury (mTBI). Studies typically examine ANAM4 using standardized scores and/ or comparisons to a baseline. A more fine-grained approach involves examining inconsistency within an individual's performance (i...

A deficit of inhibition ability is a neuropsychological problem in children with attention deficit hyperactivity disorder (ADHD). We investigated whether in children who made impulsive error (IE), less error-related negativity (ERN) would correlate with poorer executive attention functions (EAFs). Ninety children (49 with ADHD and 41 without ADHD) were investigated by a 4-minute simple reaction time task and simultaneous electroencephalogram. When they made IE, the ERN in response-locked event-related potential (ERP) was defined as error awareness...

1991 Gulf War (GW) veterans continue to experience debilitating cognitive and mood problems more than two decades following their return from deployment. Suspected causes for these cognitive complaints include additive and/or synergistic effects of the varying combinations of exposures to chemicals in theater, including pesticides and pyridostigmine bromide (PB) pills. This study was undertaken to address one of the key recommendations of the US Department of Defense Environmental Exposure Report on Pesticides, which was to conduct an epidemiological study to further evaluate the role of neurotoxicant exposures in the expression of central nervous system symptoms reported by GW veterans...

OBJECTIVES: Little is known about the affected cognitive problems in chronic low back pain patients. For this patient cohort research mostly focused on memory of pain, rather than cognitive difficulties related to pain. Chronic pain may be associated with specific (yet undefined) cognitive deficits that affect everyday behaviour. We set out to compare the cognitive function of patients with chronic low back pain (cLBP) in the course of multidisciplinary pain treatments before and after therapy...

BACKGROUND: Exercise-mediated cognitive improvements can be at least partly attributed to neuroplastic changes in the nervous system, and may be influenced by the Val66Met polymorphism of the brain-derived neurotrophic factor (BDNF) gene. Transcranial magnetic stimulation (TMS) can be used to assess mechanisms of plasticity in humans noninvasively. OBJECTIVES: To assess the feasibility of evaluating the effects of short-term regular exercise on cognitive performance, and to evaluate the relationship between these effects, TMS measures of plasticity, and BDNF Met carrier status in young healthy sedentary adults...
