The diagram helps organize their thoughts and shows the patient how they can change their behaviour in everyday situations.

They may have difficulty inhibiting many types of emotions such as anger, excitement, sadness, or frustration.

For example, when you want to take a bus, you know from past experience that you have to walk to vysexecutive bus stop, have the exact amount of change, put the change in the slot, and then you can go find a seat.

They can also have difficulty understanding others’ points of view, which can lead to anger and frustration. Series B, Biological Sciences,— Patients are taught to think of specific times they went on a holiday and then to think how they may have planned these holidays.

Both self- and independent-ratings were found to be performing reliably as outcome measures for at least a group-level. DES often occurs with other disorders, which is known as comorbidity. One of the main difficulties for an individual with DES is planning and reasoning. The vagueness of dysexeutive aspects of the syndrome has led researchers to test for it in a non-clinical sample.

Assessment of patients with DES can be difficult because traditional tests generally focus on one specific problem for a short period of time. Behavioural symptoms are evident through an individual’s actions. Execution and regulation are put into action with reminders of how to proceed if something goes wrong in the behavioural script. 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.


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

The Dysexecutive Questionnaire DEX is a tool for measuring everyday problems experienced with the dysexecutive syndrome. Perseveration is the repetition of thoughts, behaviours, or actions after they have already been completed. Cognitive symptoms refer to a person’s ability to process thoughts. The dysfunction can range from mild and subtle to severe and obvious.

Individuals with DES may have higher levels of aggression or anger because they lack abilities that are related to behavioural control. Reformulation and compensation in cognitive analytic therapy CAT. Given such stimuli, subjects no longer performed below their age group average IQ.

These tests assess executive functioning in more complex, dysexecutjve situations, which improves their ability to predict day-to-day difficulties of DES. Because of this variance, it is suggested that the most successful therapy would include multiple methods.

However, for the majority of the population such inattentiveness is questiojnaire, whereas patients with DES experience it to such a degree that daily tasks become difficult. 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.

Patients showing this symptom will begin the behaviour in the middle of conversations or during dysexecutibe tests.

Dysexecutive syndrome – Wikipedia

Training for DES patients asks them to think of a specific time when they did an activity previously. This study investigated the psychometric properties of a revised version of the measure DEX-Ra comprehensive tool, grounded in current theoretical conceptualisations of frontal lobe function and dysexecutive problems.

Rasch analysis techniques 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.


There is no cure for individuals with DES, but there are therapies to help them cope with their symptoms. The second stage, Goal Setting and Planning, consists of patients making specific goals, as well as devising a plan to accomplish them. Patients with DES seem to not be able to use this autobiographical memory as well as a normal person. Individuals with dementiadelirium or other severe psychiatric illnesses combined with DES often have disturbed sleep patterns.

If you ask them to then name colours, they may still give you animals. Exploratory and confirmatory factor analysis offers four- and five-factor solutions. This page was last edited on 11 Septemberat To accomplish this, therapists teach patients a three-step model called the General Planning Approach.

This suggests the potential usefulness of a baseline assessment measure to screen for dysexecutive impairments in individuals beginning treatment. The aim was to improve measurement of dysexecutive problems following acquired brain injury ABI. This can affect their autobiographical memory.

Dysexecutive syndrome

Dysexecutiv primarily refers to memory, the ability to learn new information, speech, and reading comprehension. Results of schizophrenic patients on the Behavioural Assessment of the Dysexecutive Syndrome BADS test discussed below are comparable to brain injured patients.

Individuals with DES will have very poor working memory and short term memory due to executive dysfunction. Each item is scored on a 5-point scale according to its frequency from never 0 qiestionnaire to very often 4 points.

People questionhaire DES often lose their social skills because their judgments and insights into what others may be thinking are impaired. The patients are then taught to monitor their executive functions and begin to evaluate them. Neurobiological brain disorder Syndromes affecting the nervous system Frontal lobe.
