An example includes “how would you plan a holiday”. The Dysexecutive Questionnaire DEX is a item questionnaire designed to sample emotional, motivational, behavioural and cognitive changes in a subject with DES.

Training for DES patients asks them to think of a specific time when they did an activity previously. People with DES often lose their social skills because their judgments and insights into what others may be thinking are impaired.

DES can also dysexecugive patients to appear self-centered and stubborn [5]. These tests assess executive functioning in more complex, real-life situations, which improves their ability to predict day-to-day difficulties of DES. Reformulation and compensation in cognitive analytic therapy CAT. Symptoms of DES fall into three broad categories: Behavioural symptoms are evident through an individual’s actions. This new version of the tool could help guide selection of interventions for different types of dysexecutive problems and provide accurate measurement in neurorehabilitation services.

Impaired planning and reasoning affect the individual’s ability to realistically assess and manage the problems of every day living. Utilization behaviour is when a patient automatically uses an object in the appropriate manner, but at an inappropriate time. This study queationnaire the psychometric properties of a revised version of the qustionnaire DEX-Ra comprehensive tool, grounded in current theoretical conceptualisations of frontal lobe function and dysexecutive problems.

Qestionnaire with DES can do fairly well on these tests because their problems are dysexecjtive to integrating individual skills into everyday tasks. Perseveration may explain why some patients appear to have obsessive-compulsive disorder. Perseveration is also often seen in patients with DES. 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. A complementary goal is to study its potential utility for initial screening in addicted individuals seeking treatment.


They are dysexecutlve taught to make questionnairw the steps go in the correct order. They are taught to write down which friend it may be, where they are going for lunch, what time they are going, how they will get there, etc.

Dysexecutive syndrome – Wikipedia

Results of schizophrenic patients on the Behavioural Assessment of the Dysexecutive Syndrome BADS test discussed below are comparable to brain injured patients. The accumulated effects of the symptoms have a large impact on daily suestionnaire. Many studies have examined the presence of DES in patients with schizophrenia.

Handbook of questlonnaire neuropsychology. 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. The central executive helps control impulses; therefore when impaired, patients have poor impulse control.

Patients showing this symptom will begin the behaviour in the middle of conversations or during auditory tests. Since planning is needed in many activities, different techniques have been used to improve this deficit in patients with DES. This page was last edited on 11 Septemberat Not all patients with frontal lobe damage have DES and some patients with no damage at all to the frontal lobe exhibit the necessary pattern of symptoms.

Deficits within this area cause many problems with every day life decisions. Individuals with DES will have very poor working memory and short term memory due to executive dysfunction. This can affect their autobiographical memory. The Dysexecutive Questionnaire DEX is a tool for measuring everyday quetsionnaire experienced with the dysexecutive syndrome. There are three types of perseveration: The most frequent cause of the syndrome is brain damage to the frontal lobe.

Given such stimuli, subjects no longer performed below their age group average IQ.

Dysexecutive syndrome

Rasch analysis uqestionnaire were employed to explore the psychometric properties of four newly developed, theoretically distinct subscales based on Stuss model of frontal lobe function and to evaluate the comparative validity and reliability of self and informant ratings of these four subscales.

The term was introduced queetionnaire Alan Baddeley [2] [3] to describe a common pattern of dysfunction in executive functionssuch as planning, abstract thinking, flexibility and behavioural control. Cognitive symptoms refer to a person’s ability to process thoughts.


The vagueness of some aspects of the syndrome has led researchers to test for it in a non-clinical sample. Also tested were the dimensionality and structural model and its convergent and discriminant validity with other instruments.

The second stage, Goal Setting and Planning, consists of patients making specific goals, as well as devising a plan to accomplish them.

Individuals with DES may have higher levels of aggression or anger because they lack abilities that are related to behavioural control. Both self- and independent-ratings were found to be performing reliably as outcome measures for at least a group-level.

Execution and regulation are put into action with reminders of how to proceed if something goes wrong in the behavioural script. To accomplish this, therapists teach patients a three-step model called the General Planning Approach.

Assessment of patients with DES can be difficult because traditional tests generally focus on one specific problem for a short period of time.

The first step can cue the patient to go to the next step in their plan.

The results show that some dysexecutive behaviours are part of everyday life, and the symptoms exist to varying degrees in everyone.

The aim was to improve measurement of dysexecutive problems following acquired brain injury ABI. They can also have difficulty understanding others’ points of view, which can lead to anger and frustration. Differences between clinical and non-clinical individuals and total scores were also analyzed.

The newly developed subscales were well targeted to dsyexecutive range dysexeuctive dysexecutive problems reported by the current sample and each displayed a good level of internal validity.

Due to multiple impairments of cognitive functioning, there can be much more frustration when expressing certain feelings and understanding how to interpret every day situations.
