Dysexecutive Syndrome

Dysexecutive Syndrome (pronounced: dis-eks-eh-kyoo-tiv sin-drohm) is a term used in neuropsychology to describe a collection of cognitive, emotional and behavioural symptoms often associated with damage to the frontal lobes of the brain.

Etymology

The term "Dysexecutive Syndrome" is derived from the Greek word "dys" meaning "bad" or "difficult", and the Latin word "executus" meaning "to execute or carry out". The term "syndrome" is derived from the Greek word "syndromē" meaning "concurrence".

Definition

Dysexecutive Syndrome is characterized by impairments in executive functions, which are higher-order cognitive processes that include problem-solving, planning, organization, and task flexibility, as well as the ability to think abstractly and to understand the implications of one's actions. These functions are primarily regulated by the frontal lobes of the brain, particularly the prefrontal cortex.

Symptoms

Symptoms of Dysexecutive Syndrome can vary widely depending on the specific areas of the frontal lobes that are damaged. Common symptoms may include:

• Difficulty with abstract thinking
• Poor problem-solving skills
• Difficulty planning and organizing
• Impulsivity
• Socially inappropriate behaviour
• Emotional instability
