Unlabelled: BACKGROUND AND PRIMARY OBJECTIVE: In recent years, the Montreal Cognitive Assessment (MoCA) has been developed to assess patients with ischemic stroke. However, it has not been validated for use on traumatic brain injury patients with intracranial haemorrhage (tICH). The aim was to evaluate the psychometric properties of the MoCA (MoCA) in such patients.
Research Design And Method: A cross-sectional observational study was carried out on 40 controls and 48 tICH patients recruited in Hong Kong. Concurrent validity was assessed by a comprehensive battery of neuropsychological tests and the Mini-Mental State Examination (MMSE). Criterion validity was assessed by the differentiation of tICH patients from controls.
Main Outcome And Results: In tICH patients, cognitive z-scores (β = 0.579; p < 0.001) and MMSE (β = 0.366, p = 0.012) significantly correlated with performance in the MoCA after adjustment for age, gender and total score for the Geriatric Depressive Scale. For the differentiation of tICH patients from controls, analysis of receiver operating characteristics curves in the MoCA revealed an optimal balance of sensitivity and specificity at 25/26 with an area under the curve of 0.704 (p = 0.001). MoCA is applicable to and significantly correlated with excellent neurological outcomes in tICH patients.
Conclusions: MoCA is a useful and psychometrically valid tool for the assessment of gross cognitive function in tICH patients.

Background: This retrospective study aimed to identify key prognostic factors for patients with traumatic intracranial hemorrhage (TICH) and develop a comprehensive nomogram for prognostic assessment.
Methods: A retrospective study was carried out on TICH patients at a single-center hospital from October 2013 to September 2022. Using logistic regression analyses, key prognostic factors for TICH were identified and used to create a predictive nomogram model.

Here we describe the derivation and validation of a prognostic nomogram for patients with Traumatic Intracranial Hemorrhage (tICH) after surgical evacuation. This is a retrospective study based on 245 patients admitted to the Department of Neurosurgery of Huashan Hospital affiliated to Fudan University, between August 2005, and August 2023. We divided the dataset into primary and validation data by the ratio of 7:3.

Cerebral microbleeds (CMBs) are small, hypointense hemosiderin deposits in the brain measuring 2-10 mm in diameter. As one of the important biomarkers of small vessel disease, they have been associated with various neurodegenerative and cerebrovascular diseases. Hence, automated detection, and subsequent extraction of clinically useful metrics (e.

Background And Importance: Traumatic intracranial hemorrhage (tICH) after mild traumatic brain injury (mTBI) is not uncommon in the elderly. Often, these patients are admitted to the hospital for observation. The necessity of admission in the absence of clinically important intracranial injuries is however unclear.

Backgrounds: The rapid expansion of an intraparenchymal hematoma following cerebral contusion often results in high mortality rates and a poor prognosis. Effective tools are essential for predicting and monitoring the incidence of traumatic intraparenchymal hematoma (tICH) and identifying patients at high risk of tICH expansion. This enables timely surgical interventions and appropriate medical management.
