The data suggest that the Spanish version of the DEX is a useful measure for assessing general symptoms of dysexecutive syndrome, and a valid, reliable and adequate screening test for estimating cognitive impairment associated with substance abuse. The aim was to improve questionnairr of dysexecutive problems following acquired brain injury ABI.

Individuals with DES will have very poor working memory and short term memory due to executive dysfunction. Patients are taught to think of specific times they went on a holiday and then to think how they may have planned these holidays.

Neurobiological brain disorder Syndromes affecting the nervous system Frontal lobe. Results of schizophrenic patients on the Behavioural Assessment of the Dysexecutive Syndrome BADS test discussed below are comparable to brain injured patients. Improving planning skills in people with traumatic brain injury through the use of an autobiographical episodic memory cueing procedure. 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.

New problems and situations may be especially poorly handled because of the inability to transfer previous knowledge to the new event. Many of the symptoms can be seen as a direct quedtionnaire of impairment to the central executive component of working memory, which is responsible for attentional control and inhibition.

Views Read Edit View history. There are three types of perseveration: One of the main difficulties for an individual with DES is planning and reasoning. 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 second stage, Goal Setting and Planning, consists of patients making specific goals, as well as devising quetionnaire plan to accomplish them. Handbook of clinical neuropsychology. The results show that some dysexecutive behaviours are part of everyday life, and the symptoms exist to varying degrees in everyone. However, for the majority of the population such inattentiveness is manageable, whereas patients with DES experience it dysexeecutive such a degree that daily tasks become difficult.

An example includes “how would you plan a holiday”. The most frequent cause of the syndrome is brain damage to the frontal lobe. DES can also cause patients to appear self-centered and stubborn [5]. Also tested were the dimensionality and structural model and its convergent and discriminant validity with other instruments.

To help patients remember how to behave, they may also create a diagram. This new ydsexecutive of the tool could help guide selection of interventions for different types of dysexecutive problems and provide accurate measurement in neurorehabilitation services.

From Wikipedia, the free encyclopedia. Due to multiple impairments of cognitive functioning, there can be much more frustration questionnalre expressing certain feelings and understanding how to interpret every day situations. They are also taught to make sure the steps go dywexecutive the correct order. 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.

DES can affect a number of functions in the brain and vary from person to person. It is thought to be Baddeley’s hypothesized working memory system and the central executive that are the hypothetical systems impaired in DES. The use of auditory stimuli has been examined in the treatment of DES.

Cognitive symptoms refer to a person’s ability to process thoughts. People with DES often lose their social skills because their judgments and insights into what others may be thinking are impaired.


Training for DES patients asks them to think of a specific time when they did an activity previously. The first step can cue the patient to go to the next step in their plan. Brain damage questionnire 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.

Autobiographical memories can be used to help direct future behaviour. The presentation of queztionnaire stimuli causes an interruption in current activity, which appears dysexecuyive aid in preventing “goal neglect” by increasing the patients’ ability to monitor time and focus on goals.

Dysexecutive syndrome

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. The emotional symptoms that individuals with DES experience may be quite extreme and can cause extensive problems. Deficits within this area cause many problems with every day life decisions.

Perseveration may explain why some patients appear to have obsessive-compulsive disorder. They may have difficulty inhibiting many types of emotions such as anger, excitement, sadness, or frustration. There is a tremendous variability in the manifestations of executive dysfunction with strong influences often apparent from the afflicted person’s personality, life experiences and intellect.

This type of perseveration refers to when a patient cannot get out of a specific frame of mind, such as when asked to name animals they can only name one.
