BACKGROUND: Reduced ability to adapt gait, particularly under challenging conditions, may be an important reason why older adults have an increased risk of falling. This study aimed to identify cognitive, psychological and physical mediators of the relationship between impaired gait adaptability and fall risk in older adults. METHODS: Fifty healthy older adults (mean±SD: 74±7years) were categorised as high or low fall risk, based on past falls and their performance in the Physiological Profile Assessment...

BACKGROUND AND AIMS: Gambling disorder (GD) and alcohol use disorder (AD) have similar features, such as elevated impulsivity and decision-making deficits, which are directly linked to relapse and poor therapeutic outcomes. Our aim was to assess decision-making characteristics in GD and AD patients compared to healthy controls (HC) based on one of the most frequently used measures of decision-making: the Iowa Gambling Task (IGT). METHODS: In our systematic literature search of three databases, we identified 1198 empirical articles that mentioned decision-making deficits with the use of the IGT in patients diagnosed with either AD or GD...

PURPOSE: Rolandic epilepsy (RE), also called benign epilepsy with centrotemporal spikes (BECTS) is the most common childhood epilepsy syndrome. RE is associated with cognitive difficulties, which can affect children's quality of life. The underlying causes of these cognitive impairments are unclear. The objective of this prospective study is to investigate sub-cortical morphological alterations in RE children with left, right, or bilateral hemispheric focus and its association with cognition...

BACKGROUND: It is well established that patients with either bipolar disorder (BD) or attention-deficit/hyperactivity disorder (ADHD) present functional impairment even when in remission. Nevertheless, research on functional impairment with adult patients with bipolar disorder comorbid to ADHD (BD+ADHD) is very scarce. The main objective of the current report was to evaluate the overall and specific domains of functioning, in patients with BD+ADHD compared to patients with pure bipolar disorder (pBD) and healthy controls (HCs)...

BACKGROUND: Psychosis in bipolar I disorder (BDI) has been associated with increased cognitive dysfunction, which may relate to poorer functional outcomes. However, it is not known whether cognition differs between BDI patients with (BDP+) or without (BDP-) history of psychosis early in the disease course, or if it is impacted by the presence of mood congruent (MCP) versus incongruent (MIC) psychotic features. We compare cognition between these groups in BDI patients recently recovered from first episode of mania...

BACKGROUND: Cognitive impairment is documented early after heart transplantation (HTx), but we lack data on cognitive function beyond the fourth year posttransplant. Against the background of good long-term survival, this knowledge is necessary to improve clinical care throughout the entire posttransplant period. METHODS: We assessed cognitive function with a neuropsychological test battery in a sample of HTx recipients ≥16 years posttransplant. To improve clinical utility, we also applied adapted consensus criteria for Mild Cognitive Impairment (MCI)...

OBJECTIVE: To assess the connection between amyloid pathology and white matter (WM) macrostructural and microstructural damage in demented patients compared with controls. METHODS: Eighty-five participants were recruited: 65 with newly diagnosed Alzheimer's disease (AD), non-AD dementia or mild cognitive impairment and 20 age-matched and sex-matched healthy controls. β-amyloid1-42 (Aβ) levels were determined in cerebrospinal fluid (CSF) samples from all patients and five controls...

Group 1 metabotropic glutamate receptors (mGlu1/5) are critical to synapse formation and participate in synaptic long-term potentiation (LTP) and long-term depression (LTD) in the brain. mGlu1/5 signaling alterations have been documented in cognitive impairment, neurodegenerative disorders, and psychiatric diseases, but underlying mechanisms for its modulation are not clear. Here, we report that transferrin receptor 1 (TFR1), a trans-membrane protein of clathrin complex, modulates the trafficking of mGlu1 in cerebellar Purkinje cells (PCs) from male mice...

BACKGROUND: The International Extranodal Lymphoma Study Group-32 (IELSG32) trial is an international randomised phase 2 study that addresses two key clinical questions in the treatment of patients with newly diagnosed primary CNS lymphoma. Results of the first randomisation have demonstrated that methotrexate, cytarabine, thiotepa, and rituximab (called the MATRix regimen) is the induction combination associated with significantly better outcome compared with the other induction combinations tested...

Allergy is associated with non-specific symptoms such as fatigue, sleep problems and impaired cognition. One explanation could be that the allergic inflammatory state includes activation of immune cells in the brain, but this hypothesis has not been tested in humans. The aim of the present study was therefore to investigate seasonal changes in the glial cell marker translocator protein (TSPO), and to relate this to peripheral inflammation, fatigue and sleep, in allergy. We examined 18 patients with severe seasonal allergy, and 13 healthy subjects in and out-of pollen season using positron emission tomography (n = 15/13) and the TSPO radioligand [(11)C]PBR28...

PURPOSE: Emergency department presentations by older people associated with mental health and drug and alcohol related conditions are increasing. However, the characteristics of presentations by older people in Australia are largely unknown. The aim of this research was to explore the characteristics of older people presenting with mental health and drug and alcohol conditions. PROCEDURES: We used a retrospective electronic medical record audit to explore all emergency department presentations by older people 65 years and over for mental health and drug and alcohol related conditions over a 12 month period...

Sport-related concussions have become a major public health concern although the long-term effects on cognitive function remain largely unknown. Event-related potentials (ERPs) are ideal for studying the long-term impact of sport-related concussions, as they have excellent temporal precision and provide insight that cannot be obtained from behavioral or neuropsychological measures alone. We reviewed all available published studies that have used stimulus or response-locked ERPs to document cognitive control processes in individuals with a history of concussion...

BACKGROUND: Several studies have identified an association between body mass index (BMI) and the incidence and severity of Alzheimer's disease (AD) but this relationship is not fully understood. OBJECTIVE: The primary objective of this study was to assess the possible association between BMI and cerebrospinal fluid (CSF) biomarkers of AD pathology in subjects with normal cognition and cognitive impairment. The secondary objective was to test whether BMI may contribute to improve the accuracy of a clinical model to predict AD pathology in memory clinic patients with cognitive impairment...

Mental time travel (MTT) allows navigation into the past, the future, and the minds of others, and it subserves future-oriented decision-making. Impaired MTT has been associated with a tendency to over-rely on the present, which is a characteristic of addictive behaviors. We here discuss the possible relationship between impaired autographical memory, future-oriented MTT, shortened time horizons, suboptimal social cognition, and poor decision-making in individuals with drug and gambling use disorders. We elaborate on how impaired MTT could compromise the process of change in addiction recovery and the effectiveness of psychotherapy...

Acute and repeated exposure to cocaine alters the cognitive performance of humans and animals. How each administration schedule affects the same memory task has yet to be properly established in nonhuman primates. Therefore, we assessed the performance of marmoset monkeys in a spontaneous object-location (SOL) recognition memory task after acute and repeated exposure to cocaine (COC; 5mg/kg, ip). Two identical neutral stimuli were explored on the 10-min sample trial, after which preferential exploration of the displaced vs the stationary object was analyzed on the 10-min test trial...

BACKGROUND AND OBJECTIVES: A huge number of solutions based on computational systems have been recently developed for the classification of cognitive abnormalities in older people, so that individuals at high risk of developing neurodegenerative diseases, such as Cognitive Impairment and Alzheimer?s disease, can be identified before the manifestation of the diseases. Several factors are related to these pathologies, making the diagnostic process a hard problem to solve. This paper proposes a computational model based on the artificial neural network to classify data patterns of older adults...

Multiple sclerosis (MS) is a neurological disorder leading to both physical and cognitive disability in young adults. These limitations harshly impact the overall subject's habits and are predictive of poor social integration, resulting in reduced working activity and limited social network [1]. To this point, among the cognitive domains that could be impaired in MS, Social Cognition (SC) can have a direct impact on this outcome, due to its involvement in social interactions.

BACKGROUND: Cognitive impairment in primary-progressive multiple sclerosis (PP-MS) is correlated with global brain atrophy. Unfortunately, brain volumes computation requires processing resources not widely available in clinical practice. Therefore we decided to test the predictive role of retinal atrophy metrics on cognitive decline, applying them as proxy of grey matter (GM) atrophy in PP-MS. METHODS: Twenty-five PP-MS patients completed the Brief International Cognitive Assessment for MS (BICAMS) and underwent spectral-domain OCT and 3...

Neuropathological and in vivo studies have revealed a tight relationship between tau pathology and cognitive impairment across the Alzheimer's disease spectrum. However, tau pathology is also intimately associated with neurodegeneration and amyloid pathology. The aim of the present study was therefore to assess whether grey matter atrophy and amyloid pathology contribute to the relationship between tau pathology, as measured with 18F-AV-1451-PET imaging, and cognitive deficits in Alzheimer's disease. We included 40 amyloid-positive patients meeting criteria for mild cognitive impairment due to Alzheimer's disease (n = 5) or probable Alzheimer's disease dementia (n = 35)...

Clinical evidence suggests that aberrant tau accumulation in the locus coeruleus and noradrenergic dysfunction may be a critical early step in Alzheimer's disease progression. Yet, an accurate preclinical model of these phenotypes that includes early pretangle tau accrual in the locus coeruleus, loss of locus coeruleus innervation and deficits locus coeruleus/norepinephrine modulated behaviours, does not exist, hampering the identification of underlying mechanisms and the development of locus coeruleus-based therapies...
