Article
Full-text available
Background: Cerebral small vessel disease (CSVD) is a highly prevalent condition associated with diffuse ischemic damage and cognitive dysfunction particularly in executive function and attention. Functional brain imaging studies can reveal mechanisms of cognitive impairment in CSVD, although findings are mixed. Methods: A systematic review integra...
Article
1 Sleep problems can mimic or worsen symptoms of attention-deficit/hyperactivity disorder (ADHD): At least 50% of children and adults with ADHD report substantial sleep problems, including delayed sleep phase syndrome and insomnia, leading to disrupted or insufficient sleep. Adults with ADHD have been shown to have high prevalence of restless leg s...
Article
Postconcussive symptoms following mild traumatic brain injury (mTBI)/concussion are common, disabling, and challenging to manage. Patients can experience a range of symptoms (e.g., mood disturbance, headaches, insomnia, vestibular symptoms, and cognitive dysfunction), and neuropsychiatric management relies heavily on nonpharmacological and multidis...

Objective The objective of this study was to investigate the impact and prevalence of sleep-wake disturbances among adult patients admitted for inpatient acquired brain injury rehabilitation. Method This was a retrospective cohort study involving all adults admitted for inpatient ABI neurocognitive rehabilitation at UHN-Toronto Rehabilitation Inst...
Article
Some degree of ischemic injury to white matter tracts occurs naturally with age and is visible on magnetic resonance imaging as focal or confluent white matter hyperintensities (WMHs). Its relationship to cognition, however, remains unclear. To explore this, community-dwelling adults between the ages 55-80 years old completed structural imaging, ne...
Article
Background Cognitive dysfunction is a key pathological feature of treatment resistant major depression (TRD) that is often overlooked (1). Persistent deficits in cognition are common and serve as a mediator of psychosocial and functional outcomes. Such deficits are associated with reduced quality of life and increased likelihood of relapsing (2). S...

Medication reconciliation in ambulatory care settings helps prevent adverse drug events. Patient involvement in the process is crucial, as clinicians must verify the reported medication history with other sources such as home medication lists or brown-bagged home medications provided by patients. However, only 47.8% of brain injury and stroke adult...

Purpose: Cancer screening may not be appropriate for some older people. We compare the likelihood of screening for colorectal, breast, and cervical cancers in older people with versus without cognitive impairment or dementia. Method: Systematic search of MEDLINE, Embase, and PsycINFO (to March 9, 2018) for articles reporting screening for colon, br...

Article
Full-text available
Objective: Traumatic brain injury (TBI) is associated with impairments in processing speed as well as higher-level cognitive functions that depend on distributed neural networks, such as regulating and sustaining attention. Although exogenous alerting cues have been shown to support patients in sustaining attentive, goal-directed behavior, the neu...
Article

Background: Combined MD/PhD programs provide a structured path for physician-scientist training, but assessment of their success within Canada is limited by a lack of quantitative data. We collected outcomes data for graduates of Canadian MD/PhD programs. Methods: We developed and implemented a Web-based survey consisting of 41 questions designed...
Article
Full-text available
The continued decline in medical trainees entering the workforce as clinician-scientists has elevated the need to engage medical students in research. While past studies have shown early exposure to generate interest among medical students for research and academic careers, financial constraints have limited the number of such formal research train...

Neuroserpin is an axonally secreted serine protease inhibitor (serpin) expressed within the nervous system. Although best known for its preferential inhibition of tissue plasminogen activator (tPA) – a commonly used clotting busting agent used by clinicians since 1996 – relatively little is known about what elements of neuroserpin are responsible i...

Patient assessment following acquired brain injury is critical for rehabilitation, however the use of traditional assessment tools breaks down when therapists are confronted with non-communicative patients (e.g. global aphasia, and vegetative state). Thus there is a need for reliable alternatives to current neuropsychological tests which rely on be...
Article
Full-text available
Background Screening for vascular risk factors is commonly assessed through self-report, despite reports of low sensitivity using this approach in healthy populations. The validity of self-reported vascular risk factors in a population at high risk for stroke has yet to be explored. Aims This study investigated the validity of self-reported cardio...

The Canadian Society of Clinician Investigators (CSCI) and Clinical Investigator Trainee Association of Canada/Association des cliniciens-chercheurs en formation du Canada (CITAC/ACCFC) annual general meeting (AGM) was held in Toronto during November 21-24, 2015 for the first time in conjunction with the University of Toronto Clinician-Investigator...
Poster
Full-text available
To use simultaneous electroencephalography and functional magnetic resonance imaging (EEG-fMRI) paired with neuropsychological testing to better characterize changes in brain functional activity associated with Cerebral Cerebral Small Vessel Disease (CSVD) and how such individuals may benefit from goal management training (GMT). CSVD is the largest...
