Study Notes

Executive Functioning

Executive functions are self-regulatory functions that organize, direct, and manage other cognitive abilities, emotional responses, and behavior. (Burgess and Alderman, 2004)
They are a complex set of processes allowing a person to plan and carry out goals, adapt to new situations, and consider consequences.
They are higher-level cognitive skills.

Aspects of Executive Functioning

Inhibition: The ability to withhold automatic responses and respond in a novel (or less automatic) manner. Patients with poor inhibitory control may be impulsive, show little self-control, and display inappropriate social behaviour. Assessment measures include the Stroop Test and sentence completion test.
Planning and Organization: Identifying steps and elements to achieve a goal. It involves imagining future situations, weighing different options, and making choices. Assessment includes tests like the Clock Drawing test, Rey Complex Figure test and Key Search test. Patients with poor planning may adopt a haphazard approach to tasks, not think ahead, and not consider options.
Cognitive Flexibility: The ability to switch between different ways of responding, adapting to changing situations. Patients with poor flexibility may exhibit rigid and concrete thinking, and perseverative responding, making it difficult to understand other viewpoints. Assessment includes the Trail-Making Test, Clock Drawing, and Sorting Task.
Concept Formation, Reasoning, and Problem Solving: Developing new concepts, strategies, using learned concepts to solve a problem, evaluating performance, considering alternatives, and thinking logically. Patients with problems in these areas may struggle to form categories, generate and implement solutions, correct errors, and use feedback. The assessment for this area can include verbal fluency tasks, spatial anticipation tasks, and reasoning based on nonverbal information.

Executive Functioning and the Frontal Lobes

Executive functions frequently relate to the frontal lobes. Although damage often impairs executive functions, these impairments are not always confined to the frontal lobe, and executive function isn't synonymous.
Most patients with frontal lobe damage do show impairments of executive functioning, however.
Specific parts of the frontal lobe (i.e., dorsoalateral, orbitofrontal, and ventromedial prefrontal cortex) are linked to specific aspects of executive function.

Conditions Affecting Executive Functioning

Traumatic Brain Injury (TBI): Impairments are common as frontal lobes are vulnerable. Nature and severity depend on injury location.
Frontotemporal Dementia: Characterized by early and progressive changes in personality, behaviour, and executive functioning, such as disinhibition, impulsivity, mental rigidity, poor insight, loss of empathy, and apathy.
Schizophrenia: Significant impairments in executive functioning compared to controls and other psychiatric groups; also characterized by poor cognitive flexibility, impaired planning, and poor insight.
