It has been shown that damage, such as lesions, in other areas of the brain may indirectly affect executive functions and lead to similar symptoms. Also tested were the dimensionality and structural model and its convergent and discriminant validity with other instruments.

The newly developed subscales were well targeted to the range of dysexecutive problems reported by the current sample and each displayed a good level of internal validity. Improving planning skills in people with traumatic brain injury through the use of an autobiographical episodic memory cueing procedure. Patients with DES seem to not be able to use this autobiographical memory as well as a normal person.

This treatment method has resulted in improved daily executive functioning, however no improvements were seen on formal executive functioning tests. From Wikipedia, the free encyclopedia. If you ask them to then name colours, they may still give you animals. Handbook of clinical neuropsychology.

People with DES can do fairly well on these tests because their problems are related to integrating individual skills questoinnaire everyday tasks. It is thought to be Baddeley’s hypothesized working memory system and the central executive that are the hypothetical systems impaired in DES. Patients with Alzheimer’s disease and other forms of dementia have been shown to exhibit impairment in executive functioning as well.


Not all patients with frontal lobe damage have DES and some patients with no damage at all to the frontal lobe exhibit the dysececutive pattern of symptoms.

Brain damage leading to the dysexecutive pattern of symptoms can result from physical trauma such as a blow to the head or a stroke [6] or other internal trauma.

Impaired planning and reasoning affect the individual’s ability to realistically assess and manage the problems of every day living. There is no cure for individuals with DES, but there dysexecutiv therapies to help them cope with their symptoms.

To help patients remember how to behave, they may also create a diagram. Individuals with DES may have higher levels of aggression or anger because they lack abilities that are related to behavioural control.

Dysexecutive syndrome

Patients showing this symptom will begin the behaviour in the middle of conversations or during auditory tests. Differences between clinical and non-clinical individuals and total scores were also analyzed.

The presentation of auditory stimuli causes an interruption in current activity, which appears to aid in dgsexecutive “goal neglect” questionaire increasing the patients’ ability to monitor time and focus on goals.

Many of the symptoms can be seen as a direct result of impairment to the central executive component of working memory, which is responsible for attentional control and inhibition. However, for the majority of the population such inattentiveness is manageable, whereas patients with DES experience it to such a degree that daily tasks become difficult. Neurobiological brain disorder Syndromes affecting the nervous system Frontal lobe.


The dysfunction can range from mild and subtle to severe and obvious. The final stage, named Initiation, Execution, and Regulation, requires patients to implement their goals in their everyday lives. The second stage, Goal Setting and Planning, consists of patients making specific goals, as well as devising a plan to accomplish them. They are taught to write down which friend it may be, where they dyseecutive going for lunch, what time they are quesgionnaire, how they will get there, etc.

Another method of reminding is to have patients write a letter to themselves.

The diagram helps organize their thoughts and shows the questionnalre how they can change their behaviour in everyday situations. The accumulated effects of the symptoms have a large impact on daily life. People with DES often lose their social skills because their judgments and insights into what others may be thinking are impaired.

The term was introduced by Alan Baddeley [2] [3] to describe a common pattern of dysfunction in executive functionssuch as planning, abstract thinking, flexibility and behavioural control. Patients in the chronic phase of the disorder have significantly lower scores than those who are acute.
