Pre-injury psychiatric history, subacute symptoms and personality traits predict social reintegration at 3-month post-mild traumatic brain injury.

Background: The purpose of the study was to identify whether the presence of a pre-injury psychiatric history, subacute post-concussive symptoms (PCS) and personality traits were predictive of less favorable social reintegration for 3 months following a mild traumatic brain injury (mTBI).

Method: A total of 76 patients with mTBI were included, and the presence of a pre-injury psychiatric history was identified from the medical chart. One-month post-accident, these patients completed the assessing personality traits and the to measure subacute PCS.

Relationships between predisposing, precipitating, and perpetuating factors and executive functioning following mild traumatic brain injury.

Introduction: The aim of this study was to determine the sociodemographic and MTBI-related variables associated with executive functioning (EF).

Methods: Based on the theoretical model of Hou and colleagues, data on predisposing (age, education, premorbid IQ), precipitating (post-traumatic amnesia, loss of consciousness, presence of frontal lesions, post-accident time to evaluation) and perpetuating (anxious and depressive affects and post-concussive symptoms) factors were retrospectively collected from the medical records of 172 patients with MTBI. EF data based on the 3 processes included in Miyake's prediction model (2000) () were collected using respectively the Digit span task of the Weschler - 4 edition, the Trails A and B as well as the initiation time on the Tower of London- Drexel University.

Longitudinal recovery of executive functions and social participation prediction following traumatic brain injury.

There is heterogeneity across studies and a lack of knowledge about recovery of EFs over time following traumatic brain injury (TBI). Also, EFs are associated with functional outcome, but there is still a gap in knowledge concerning the association between EFs and social participation following TBI. For this reason, we aim to (1) measure the recovery of the three executive function subcomponents of Miyake's model, namely flexibility, updating and inhibition between the acute phase (T1) and 6 months post TBI (T2) and (2) measure the relationship between EFs and social participation after TBI.

Criterion validity of a functional cognitive task in patients with severe traumatic brain injury.

Primary Objective: To verify criterion validity of measures from a functional cognitive task (FCT) carried out with patients with severe traumatic brain injury (sTBI) at 2-5 years post-injury.

Methods And Procedures: Forty-six patients with sTBI took part in a long-term outcome study where the FCT and the Neurobehavioural Rating Scale-Revised (NBRS-R) were administered and the FIM™ instrument was rated. The FCT is a telephone information gathering task for evaluating functional cognitive skills.

Long-term outcome after severe traumatic brain injury: the McGill interdisciplinary prospective study.

Objective: To obtain a comprehensive understanding of long-term outcome after severe traumatic brain injury (sTBI).

Participants: Forty-six patients with sTBI.

Design: Comparison of interdisciplinary evaluation results at discharge from acute care and at 2 to 5 year follow-up.
