Thirty-five multiple sclerosis (MS) patients diagnosed according to the Poser criteria were examined in a variety of cognition and memory tasks. Their performance was compared to age- and gender-matched healthy individuals. While there was no difference in overall intellectual performance and short-term memory between the MS group and control subjects, the patient group showed significant deficits in several everyday memory tasks including story recall, object and face recognition, procedural, topographical and prospective memory tasks. An intra-group comparison in the MS cohort revealed that those patients with a chronic-progressive MS course exhibited the most substantial everyday memory impairments and highest EDSS scores. These findings coincide with the neuroradiological, semiquantitative lesion analysis which was also performed. In this analysis, the latter MS subgroup also had the highest lesion score, as a sign of an overall brain involvement.

Real-time mechanism-based interventions for daily alcohol challenges: Protocol for ecological momentary assessment and intervention.
Digit Health
January 2025
Department of Psychiatry and Psychotherapy, Central Institute of Mental Health, Medical Faculty Mannheim/Heidelberg University, Mannheim, Germany.
Background: Advancing evidence-based, tailored interventions for substance use disorders (SUDs) requires understanding temporal directionality while upholding ecological validity. Previous studies identified loneliness and craving as pivotal factors associated with alcohol consumption, yet the precise directionality of these relationships remains ambiguous.
Objective: This study aims to establish a smartphone-based real-life intervention platform that integrates momentary assessment and intervention into everyday life.
Investigating canonical size phenomenon in drawing from memory task in different perceptual conditions among children.
Sci Rep
January 2025
PSYCLE, Aix Marseille Univ, Aix en Provence, France.
The canonical size phenomenon refers to the mental representation of real-object size information: the objects larger in the physical world are represented as larger in mental spatial representations. This study tested this phenomenon in a drawing-from-memory task among children aged 5, 7, and 9 years. The participants were asked to draw objects whose actual sizes varied at eight size rank levels.

Introduction: This study aimed to clarify the relationship between anxiety about the possibility of developing dementia (dementia onset anxiety) and subjective memory impairment in frail older individuals who require long-term care and are experiencing declining cognitive function.
Methods: This study included 30 frail older individuals requiring long-term care who completed the Everyday Memory Checklist (EMC), which was simultaneously performed by an occupational therapist (OT). Individuals were divided into two groups: with and without anxiety about dementia onset.
Validation of Spatial Orientation Screening questionnaire for use in memory clinic patients.

January 2025
Department of Geriatric Medicine, Oslo University Hospital, Oslo, Norway.
Background: Spatial orientation is required for independent mobility in society. Deficits in spatial orientation can be an early symptom of Alzheimer's disease and other dementias, and there is a need for brief assessment tools to identify impairments.
Objective: The aim of this study was to evaluate the construct and known-group validity of our newly developed Spatial Orientation Screening (SOS) questionnaire.

Objective: Sleep disturbance (SD) is common after pediatric mild traumatic brain injury (mTBI) and may predict increased postconcussive symptoms (PCS) and prolonged recovery. Our objective was to investigate the relation of SD with PCS in children with mTBI and those with orthopedic injury (OI).
Setting: Emergency departments (EDs) at 2 children's hospitals in the Midwestern United States.
