Prevalence and risk factors of delirium in the intensive care unit: An observational study
2020
Background: Several risk factors, such as age, alcohol abuse, dementia, and severe illness, can contribute to the development of delirium. However, limited information is available in the literature regarding the risk of delirium among surgical, trauma, neurological, and medical intensive care patients. Aims and objectives: To describe the prevalence of risk factors associated with delirium in intensive care units. Design: This study used an observational design. Methods: We enrolled 165 patients hospitalized in two intensive care units in Italy. Patients were first evaluated using the Prediction of Delirium model and were subsequently evaluated using the Intensive Care Delirium Screening C…
A case of post-traumatic complex auditory hallucinosis treated with rTMS.
2010
Previous studies of auditory hallucinations in schizophrenia found that the hallucinations were reduced by the application of transcranial magnetic stimulation (rTMS). Here we describe a case of traumatic brain injury associated with continuous music hallucinations. An MRI scan showed a structural lesion of the right temporal pole and a PET scan indicated a hyperactive area of the posterior right temporal lobe. We hypothesized that rTMS applied to the right temporal area would reduce this activity and the corresponding hallucinations. The patient's music hallucinations were significantly reduced by rTMS treatment. A PET scan following treatment also indicated that rTMS treatment reduced bra…
rTMS evidence of different delay and decision processes in a fronto-parietal neuronal network activated during spatial working memory.
2003
The existence of a specific and widely distributed network for spatial working memory (WM) in humans, involving the posterior parietal cortex and the prefrontal cortex, is supported by a number of neuroimaging studies. We used a repetitive transcranial magnetic stimulation (rTMS) approach to investigate the temporal dynamics and the reciprocal interactions of the different areas of the parieto-frontal network in normal subjects performing a spatial WM task, with the aim to compare neural activity of the different areas in the delay and decision phases of the task. Trains of rTMS at 25 Hz were delivered over the posterior parietal cortex (PPC), the premotor cortex (SFG) and the dorsolateral …
When the amnestic mild cognitive impairment disappears: characterisation of the memory profile
2009
BACKGROUND/OBJECTIVES: Subjects affected by mild cognitive impairment (MCI) may improve during the observation period. This is the first study investigating qualitative features of memory deficits in subjects affected by reversible MCI [reversible cognitive impairment (RCI)]. METHODS: Baseline cognitive and memory performances of 18 subjects affected by amnestic MCI who had normalized cognitive performances at follow-ups were compared with those of 76 amnestic MCI subjects who still showed impaired cognitive performances at the 24-month follow-up (MCI) and with those of a group of 87 matched control subjects (normal controls). RESULTS: Compared with normal controls the memory deficit in the…
What makes music memorable? : Relationships between acoustic musical features and music-evoked emotions and memories in older adults
2021
Publisher: Public Library of Science; International audience; Music has a unique capacity to evoke both strong emotions and vivid autobiographical memories. Previous music information retrieval (MIR) studies have shown that the emotional experience of music is influenced by a combination of musical features, including tonal, rhythmic, and loudness features. Here, our aim was to explore the relationship between music-evoked emotions and music-evoked memories and how musical features (derived with MIR) can predict them both. Methods Healthy older adults (N = 113, age ≥ 60 years) participated in a listening task in which they rated a total of 140 song excerpts comprising folk songs and popular…
Cognitive Reserve Proxies Do Not Differentially Account for Cognitive Performance in Patients with Focal Frontal and Non-Frontal Lesions
2020
AbstractObjective:Cognitive reserve (CR) suggests that premorbid efficacy, aptitude, and flexibility of cognitive processing can aid the brain’s ability to cope with change or damage. Our previous work has shown that age and literacy attainment predict the cognitive performance of frontal patients on frontal-executive tests. However, it remains unknown whether CR also predicts the cognitive performance of non-frontal patients.Method:We investigated the independent effect of a CR proxy, National Adult Reading Test (NART) IQ, as well as age and lesion group (frontal vs. non-frontal) on measures of executive function, intelligence, processing speed, and naming in 166 patients with focal, unila…
Recommendations for standardization and phenotype definitions in genetic studies of osteoarthritis: the TREAT-OA consortium
2011
Objective: To address the need for standardization of osteoarthritis (OA) phenotypes by examining the effect of heterogeneity among symptomatic (SOA) and radiographic osteoarthritis (ROA) phenotypes. Methods: Descriptions of OA phenotypes of the 28 studies involved in the TREAT-OA consortium were collected. We investigated whether different OA definitions result in different association results by creating various hip OA definitions in one large population based cohort (the Rotterdam Study I (RSI)) and testing those for association with gender, age and body mass index using one-way ANOVA. For ROA, we standardized the hip-, knee- and hand ROA definitions and calculated prevalence's of RO…
DSM-IV Combined Type ADHD Shows Familial Association With Sibling Trait Scores
2008
Contains fulltext : 69060.pdf (Publisher’s version ) (Closed access) Attention deficit hyperactivity disorder (ADHD) is a discrete clinical syndrome characterized by the triad of inattention, hyperactivity, and impulsivity in the context of marked impairments. Molecular genetic studies have been successful in identifying genetic variants associated with ADHD, particularly with DSM-IV inattentive and combined subtypes. Quantitative trait locus (QTL) approaches to linkage and association mapping have yet to be widely used in ADHD research, although twin studies investigating individual differences suggest that genetic liability for ADHD is continuously distributed throughout the population, u…
Investigating Bidirectional Links Between the Quality of Teacher-Child Relationships and Children’s Interest and Pre‐Academic Skills in Literacy and …
2020
This study investigated bidirectional links between the quality of teacher–child relationships and children's interest and pre‐academic skills in literacy and math. Furthermore, differences in the patterns of bidirectionality between boys and girls were explored. Participants were 461 Finnish kindergarteners (6‐year‐olds) and their teachers (n = 48). Teachers reported their closeness and conflict with each child twice throughout the kindergarten year. Children rated their interest in literacy and math, and were tested on their pre‐academic skills. Cross‐lagged path models indicated that teacher‐perceived conflict predicted lower interest and pre‐academic skills in both literacy and math. Re…
Long-Term Response to Cholinesterase Inhibitor Treatment Is Related to Functional MRI Response in Alzheimer's Disease.
2015
<b><i>Background:</i></b> Treatment of Alzheimer's disease (AD) with cholinesterase inhibitors (ChEI) enhances cholinergic activity and alleviates clinical symptoms. However, there is variation in the clinical response as well as system level changes revealed by functional MRI (fMRI) studies. <b><i>Methods:</i></b> We investigated 18 newly diagnosed mild AD patients with fMRI using a face recognition task after a single oral dose of rivastigmine, a single dose of placebo and 1-month treatment with rivastigmine. The clinical follow-up took place at 6 and 12 months. <b><i>Results:</i></b> MMSE score difference between bas…
