Executive Function and Rehabilitation
We have been active in the development of new assessment tools to assess executive or frontal lobe functions. We have been especially interested in self-regulation, commonly affected by damage to ventral frontal regions, as well as diffuse injury. The Strategy Application Test (Levine et al., 1998; Levine et al., 2000), is a tabletop measure that simulates the uncertainty inherent in real life situations and shows strong relationships to real-life outcome in patients with TBI. This work has been supplemented by studies exploring the relationship of novel and standard “frontal” tests to type and location of brain damage in patients with TBI (Fujiwara et al., 2008, Levine et al., 2005). The theoretical framework for this research, including the importance of process analysis and intra-frontal localization, was described in (Stuss and Levine, 2002). An article in Scientific American: Mind concerns the effects of serious mental illness on executive and prefrontal function, using the singer Brian Wilson as a case study (Levine, 2005). |
In a separate line of research, lifelong occupation is treated as a naturally occurring method of practice to build specific foci of brain reserve that is in turn related to patterns of neurodegeneration in patients with frontotemporal lobar degeneration (FTLD; Spreng et al., 2010, 2011). We demonstrated that specific occupational practices are associated with specific volumetric or brain metabolic patterns, either due to buildup of brain reserve through repeated practice or pre-existing functional capacity differences.
Cerebral small vessel disease
Cerebral small vessel disease is a major contributor to age-related cognitive decline. It is enhanced by vascular risk factors (e.g., obesity, hypertension, diabetes, high cholesterol) and it can progress to vascular cognitive impairment, a common cause of dementia. Furthermore, cerebral small vessel disease can exacerbate the effects of dementia due to other causes, including Alzheimer's disease.
Dey et al., (2016) reviewed neuroimaging research demonstrating the effects of these conditions on the functioning of distributed brain networks, as measured by functional MRI and electroencephalography (including both event-related potentials (ERPs) and spectral analyses). These brain changes affect the ability to focus attention and keep goals active in consciousness. We are currently studying novel neuroimaging assessment of cerebral small vessel disease and treatment methods to compensate for its effects on behaviour.

Goal Management Training™
Many patients with brain disease affecting the frontal lobes or distributed brain networks suffer from significant daily life disruption due to executive dysfunction, concentration, impulse control, planning, and use of feedback. Goal Management Training ™ , developed in collaboration with Ian Robertson and Tom Manly, is a practical, manualized intervention that addresses these deficits through education, task practice, narrative structure, and mindfulness practice.
GMT is centered on a simple instruction, to “STOP!" the automatic pilot and state one’s goals periodically before and during task execution. The theoretical framework for this intervention is derived from the hypothesis that the brain’s sustained attention network supports executive function. Lapses in sustained attention associated with slips of intention can be avoided through periodic alerting of the sustained attention system (for neuroimaging support, see O'Connor et al., 2011). This program has been validated in healthy aging, traumatic brain injury, spina bifida, multiple sclerosis, stroke, abstinent polysubstance abuse, and post-critical care patients (for review and meta-analysis, see Stamenova et al., 2018) For more information on GMT, check out GoalManagementTraining.com.
