Lateralization Effects on Cerebral Blood Flow in Patients With Unilateral Pulsatile Tinnitus Measured With Arterial Spin Labeling
2020
Purpose: To investigate cerebral blood flow (CBF) differences in patients with left- and right-sided pulsatile tinnitus (LPT and RPT) and healthy controls (HCs) to further explore the lateralization effects of PT using arterial spin labeling (ASL). Methods: ASL data from 21 RPT patients, 17 LPT patients and 21 HCs were reviewed. Voxel-wise analysis and region of interest analysis were performed to explore differences in CBF among the three groups. Tinnitus Handicap Inventory (THI) score and tinnitus duration were obtained from each patient. Results: Voxel-wise analysis showed that the CBF of the left inferior parietal gyrus was increased in both RPT and LPT patients compared with HCs (P < 0…
Perspectives actuelles dans la microdélétion 22q11.2 : prise en charge du phénotype neurocomportemental
2015
Resume La microdeletion 22q11.2 est le syndrome microdeletionnel le plus frequent de la population generale. Le phenotype associe des anomalies de l’appareil pharynge embryonnaire a un phenotype neurocomportemental. La presentation clinique du syndrome est extremement variable d’un individu a l’autre, quelle que soit la taille de la deletion, et plus de 180 manifestations ont ete decrites, aucune n’etant pathognomonique. Les symptomes psychiatriques, particulierement de nature psychotique, sont frequents dans la microdeletion 22q11.2 et de nombreux psychiatres sont amenes a rencontrer ces patients. La prise en charge doit tenir compte des particularites du syndrome. L’evaluation de la neuro…
Post-encoding stress does not enhance memory consolidation: The role of cortisol and testosterone reactivity
2020
In contrast to the large body of research on the effects of stress-induced cortisol on memory consolidation in young people, far less attention has been devoted to understanding the effects of stress-induced testosterone on this memory phase. This study examined the psychobiological (i.e., anxiety, cortisol, and testosterone) response to the Maastricht Acute Stress Test and its impact on free recall and recognition for emotional and neutral material. Thirty-seven healthy young men and women were exposed to a stress (MAST) or control task post-encoding, and 24 h later, they had to recall the material previously learned. Results indicated that the MAST increased anxiety and cortisol levels, b…
Effects of a Vibro-Tactile P300 Based Brain-Computer Interface on the Coma Recovery Scale-Revised in Patients With Disorders of Consciousness
2020
Persons diagnosed with disorders of consciousness (DOC) typically suffer from motor and cognitive disabilities. Recent research has shown that non-invasive brain-computer interface (BCI) technology could help assess these patients’ cognitive functions and command following abilities. 20 DOC patients participated in the study and performed 10 vibro-tactile P300 BCI sessions over 10 days with 8–12 runs each day. Vibrotactile tactors were placed on the each patient’s left and right wrists and one foot. Patients were instructed, via earbuds, to concentrate and silently count vibrotactile pulses on either their left or right wrist that presented a target stimulus and to ignore …
Norwegian Football Academy Players – Player´S Self-Assessed Skills, Stress and Coach-Athlete Relationship
2017
Background: Being part of a football academy environment is associated with many advantages. Even so, academy players will also encounter a range of personal and interpersonal challenges that might affect their development, including stress and the coach-athlete relationship. Objective: This study’s purpose was to investigate how football academy players assessed their own skills compared to their teammates, and how this is associated with perceived stressors and their perceived relationship with their coach. Method: Participants (N= 122) represented 3 football academies (12-19 years old). Instruments used were CART-Q and a modified version of the Adolescent Stress Questionnaire. Results: …
Directional Control Mechanisms in Multidirectional Step Initiating Tasks.
2020
Typical anticipatory postural adjustments (APAs) in forward gait or step initiation tasks to prepare for possible disturbances caused by prime voluntary movements and to accelerate the body forward have been previously reported. However, it is not clear how wide the variations in step directions are differentiated and controlled in non-forward step initiation tasks during the APA phase. The main goal of this study is to explain the directional control mechanisms by investigating the APA of step initiation tasks in forward, diagonal, lateral, and posterior directions. The center of pressure (COP) trajectories and related muscle (soleus, tibialis anterior, and gluteus medius of both lower lim…
Self-reported sleep duration and cognitive functioning in the general population
2009
This study investigated the relationship between self-reported sleep factors (sleep duration, insomnia, use of sleeping medicine, probable sleep apnoea and feelings of fatigue and tiredness) with cognitive functioning in 5177 people aged 30 years or older from a cross-sectional representative sample of the adult population in Finland (The Finnish Health 2000 Survey). Previous studies have indicated a U-shaped association between increased health risks and sleep duration; we hypothesized a U-shaped association between sleep duration and cognitive functioning. Objective cognitive functioning was assessed with tasks derived from the Consortium to Establish a Registry for Alzheimer's Disease te…
A Mindfulness-Based Program Improves Health in Caregivers of People with Autism Spectrum Disorder: a Pilot Study
2014
Mindfulness-based interventions have demonstrated to be effective in reducing stress and health complaints in clinical populations. However, to our knowledge, biological health markers have not been used in studies of the effectiveness of mindfulness programs in caregivers of people with autism spectrum disorders (ASDs). This study aimed to assess the effects of a mindfulness intervention on mood disturbances and health complaints in this population compared with non-caregivers. The design of the study was quasi-experimental, with repeated measures. Self-reported health, cortisol awakening response (CAR), and afternoon cortisol levels before and after a mindfulness session were assessed at …
A Positive Technology System for the Promotion of Well-Being: From the Lab to the Hospital Setting
2016
There is growing evidence of the effectiveness of Positive Psychology Interventions (PPIs) to enhance subjective and psychological well-being in different populations, and the Information and Communication Technologies (ICTs) are becoming into a key help to increase the efficiency of this type of interventions. Recently, the use of technology to foster well-being and personal growth has been named as Positive Technology. The aim of this paper is to describe and to present data about a positive technology example (EARTH of Well-being system) and to examine its usefulness in different populations and settings. Data of four studies are presented: two with non-clinical population (university st…
Ramadan Observance during Pregnancy in Germany: a Challenge for Prenatal Care.
2018
Abstract Introduction Fasting during Ramadan while pregnant has been shown to have long-term negative effects on the offspringʼs physical and cognitive health. Even though most Muslims do not believe pregnant women are obligated to fast during Ramadan, fasting rates of up to 87% have been reported for pregnant women. No data exists to date about Ramadan adherence and behavior in Germany. Methods The Mainz Study of Ramadan and Pregnancy surveyed pregnant Muslims and new Muslim mothers in Mainz between October 2016 and January 2017 and collected information on Ramadan adherence and behavior. We also collected data on personal characteristics and opinions, to identify determinants of fasting u…
