(1) To determine patterns of return to work (RTW) after traumatic brain injury and other causes of acquired brain injury (ABI) among young adults aged 19-30 years and (2) to compare the stability of long-term labor-market attachment (LMA) to the background population. Nationwide registry-based inception cohort study of 10 years weekly data of employment status. Patients ( = 8,496) aged 19-30 years with first-ever diagnosis of TBI, stroke, subarachnoid hemorrhage, encephalopathy, brain tumor, or CNS infections during 1999-2015.

Background: We estimated the annually incidence and mortality of acquired brain injury (ABI) in people aged 15-30 years during 1994-2013.

Methods: All Danes with a first-ever hospital diagnosis of ABI, including traumatic brain injury (TBI), encephalopathy, CNS-infection or brain tumour, were identified in the Danish National Patient Register. Incidence rates (IRs) and estimated annual percentage changes (EAPC) were estimated by Poisson regression.

Article Synopsis
  • A study was conducted to compare fatigue levels in adolescents and young adults with acquired brain injury (ABI) to healthy controls (HCs), focusing on the effects of gender, age, and education.
  • Results showed that individuals with ABI experienced significantly higher fatigue (73%) compared to HCs (29%), with female patients reporting more fatigue on certain subscales.
  • Age did not impact fatigue levels, and education levels revealed some differences, particularly in mental fatigue and reduced activity, but no strong patterns were consistently identified.

Introduction: Cognitive impairments are frequent in stroke. Cognitive testing is important for research, prognostication and planning in sub-acute stroke, but poses difficulties due to aphasia, hemineglect, hemiplegia and fatigue. We present the first steps towards a validation of a novel iPad-based test battery: Cognitive Assessment at Bedside for iPad (CABPad).

Objective: To describe the work of an interdisciplinary visual team in a stroke unit providing early identification and assessment of patients with visual symptoms, and secondly to investigate frequency, type of visual deficits after stroke and self-evaluated impact on everyday life after stroke.

Methods: For a period of three months, all stroke patients with visual or visuo-attentional deficits were registered, and data concerning etiology, severity and localization of the stroke and initial visual symptoms were registered. One month after discharge patients were contacted for follow-up.

Background: Studies have reported increasing incidence of ischemic stroke in adults younger than 50 to 55 years. Information on temporal trends of other stroke subtypes and transient ischemic attack (TIA) is sparse. The aim of this study was to investigate temporal trends of the incidence of hospitalizations for TIA and stroke including sex- and subtype-specific trends in young adults aged 15 to 30 years.

Article Synopsis
  • The study investigated the effectiveness of a nine-week group-based Cognitive Behavioural Therapy (CBT) intervention on patients with Chronic Post-Traumatic Headache (CPTH).
  • The results showed that CBT had minimal impact on headaches, pain thresholds, and only slightly affected quality of life and psychological symptoms, while the waiting-list group demonstrated a decrease in symptoms over time.
  • The findings suggest that managing CPTH remains challenging and highlight the necessity for further research to evaluate the efficacy of psychological therapies like CBT in different stages or severity of CPTH.

Objective: To explore the extent and nature of cognitive deficits in patients with idiopathic intracranial hypertension (IIH) at the time of diagnosis and after 3 months of treatment.

Design: Prospective case-control study.

Setting: Neurological department, ophthalmological department and a tertiary headache referral clinic at a Danish university hospital.

Background: The aetiology behind chronic post-traumatic headache (CPTH) after mild head injury is unclear and management is complicated. In order to optimize treatment strategies we aimed to characterize a CPTH population.

Methods: Ninety patients with CPTH and 45 patients with chronic primary headaches were enrolled from the Danish Headache Center.

Background: The predictors of functional capacity in first episode schizophrenia among seven separable cognitive domains and clinical variables are unknown.

Aim: To investigate predictors of functional capacity in first episode schizophrenia and the associations between functional capacity and measures of real-world functioning.

Methods: Socio-demographic, clinical, and cognitive measures from a sample of patients with first episode schizophrenia spectrum disorders aged 18-34years (N=117) were examined at baseline, 4-month follow-up, and 10-month follow-up and used to predict concurrent and longitudinal functional capacity.

Background: Up to 85% of patients with schizophrenia demonstrate cognitive dysfunction in at least one domain. Cognitive dysfunction plays a major role in functional outcome. It is hypothesized that addition of cognitive training to a comprehensive psychosocial programme (OPUS) enhances both cognitive and everyday functional capacity of patients more than the comprehensive psychosocial programme alone.

Article Synopsis
  • Presurgical functional MR imaging (fMRI) could potentially replace intraoperative electrocortical stimulation (ES) for mapping language function during surgeries.
  • Although fMRI provides useful insights, such as identifying which hemisphere is language-dominant and assessing proximity to language areas,
  • it currently has technical and conceptual limitations that make it less reliable than ES for surgical planning.
  • Preliminary clinical experiences support the idea that while fMRI is helpful, it shouldn't fully replace traditional methods yet.
