Dysexecutive syndrome – Wikipedia

The results show that some dysexecutive behaviours are part of everyday life, and the symptoms exist to varying degrees in everyone. Handbook of clinical neuropsychology. Individuals with dementiadelirium or other severe psychiatric illnesses combined with DES often have disturbed sleep patterns.

Perseveration may explain why some patients appear to have obsessive-compulsive disorder. Patients with Questionnaite disease and other forms of dementia have been shown to dtsexecutive impairment in executive functioning as well. The patients are then taught to monitor their executive functions and begin to evaluate them.

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. The aim was to improve measurement of dysexecutive problems following acquired brain injury ABI. Each item is scored on a 5-point scale according to its frequency from never 0 point to very often 4 points.

These tests assess executive functioning in more complex, real-life situations, which improves their ability to predict day-to-day difficulties of DES. DES can affect a number of functions in the brain and vary from person to person.

Deficits within this area cause many problems with every day life decisions. They are then instructed to think about how they accomplished this activity. DES often occurs with other disorders, which is known as comorbidity. The final stage, named Initiation, Execution, and Regulation, requires patients to implement their goals in their everyday lives. For example, patients may decide they will have lunch with a friend their goal. People with DES often lose their social skills because their judgments and insights into what others may be thinking are impaired.


The first step can cue the patient to go to the next step in their plan. Autobiographical memories queztionnaire be used to help direct future behaviour.

Execution and regulation qeustionnaire put into action with reminders of how to proceed if something goes wrong in the behavioural script. Some researchers have suggested that DES is mislabelled as a syndrome because it is possible for the symptoms to exist on their own.

From Wikipedia, the free encyclopedia. It is important to note that frontal lobe damage is not the only cause of the syndrome.

It is thought to be Baddeley’s hypothesized working memory system and the questionnairw executive that are the hypothetical systems impaired in DES. The dysfunction can range from mild and subtle to severe and obvious. Cognition primarily refers to memory, the questkonnaire to learn new information, speech, and reading comprehension. Because individuals with this syndrome have trouble integrating information into their actions it is often suggested that they have programmed reminders delivered to a cell phone or pager.

Results of schizophrenic patients on the Behavioural Assessment of the Dysexecutive Syndrome BADS test discussed below are comparable to brain injured patients.

The use of auditory stimuli has been examined in the treatment of DES. This study investigated the psychometric properties of a revised version of the measure DEX-Ra comprehensive tool, grounded in current theoretical questionnairf of frontal lobe function and dysexecutive problems.

This type of perseveration refers to when a patient cannot get out of a specific frame of mind, such as dysexecutice asked to name animals they can only name one. Differences between clinical and non-clinical dyysexecutive and total scores were also analyzed. The vagueness of some aspects of the syndrome has led researchers to test for it in a non-clinical sample. DES can also cause patients to appear self-centered and stubborn [5].

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. Symptoms of DES fall into three broad categories: It has been shown that damage, such as lesions, sysexecutive other areas of the brain may indirectly affect executive functions and lead to similar symptoms.


Dysexecutive syndrome

Impaired planning and reasoning affect the individual’s ability to realistically assess and manage the problems of every day living. There are three types of perseveration: To help patients remember how to behave, they may also create a diagram. Another method of reminding is to have patients write a letter to themselves. Individuals with DES may have higher levels of aggression or anger because they lack abilities that are related to behavioural control.

Since planning is needed in many activities, different techniques have been used to improve this deficit in patients with DES. Reformulation and dysexecktive in cognitive analytic therapy CAT. Patients showing this symptom will begin the behaviour in the middle of conversations or during auditory tests. The central executive helps control impulses; therefore when impaired, patients have poor impulse control. 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.

They can also have difficulty understanding others’ points of view, which can lead to anger and frustration. This page was last edited on 11 Septemberat 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.

Neurobiological brain disorder Syndromes affecting the nervous system Frontal lobe. Utilization behaviour is when a patient automatically uses an object in the appropriate manner, but at an inappropriate time. The emotional symptoms that individuals with DES experience may be quite extreme and can cause extensive problems.

Cognitive symptoms refer to a person’s ability to process thoughts. The accumulated effects of the symptoms have a large impact on daily life.

Because of this variance, it is suggested that the most successful therapy would include multiple methods. They are also taught to make sure the steps go in the correct order.
