What causes dysexecutive syndrome?
Dysexecutive syndrome can result from many causes, including head trauma, tumors, degenerative diseases, and cerebrovascular disease, as well as in several psychiatric conditions, including schizophrenia, attention deficit disorder, and antisocial personality disorder.
Which part of the brain is associated with dysexecutive syndrome?
Causes. The most frequent cause of the syndrome is brain damage to the frontal lobe. Brain damage leading to the dysexecutive pattern of symptoms can result from physical trauma such as a blow to the head or a stroke or other internal trauma.
What is meant by the term dysexecutive syndrome?
The term ‘dysexecutive syndrome’ refers to a dysregulation of executive functions and is strictly associated to frontal lobe damage. Dysexecutive syndrome typically encompasses emotional, motivational and behavioural symptoms, as well as cognitive deficits.
What are the symptoms of dysexecutive syndrome?
According to diagnostic criteria proposed by Godefroy et al. (2010), dysexecutive syndrome includes cognitive (e.g., deficits in response inhibition, set-shifting, and information generation) and/or behavioral (e.g., apathy, distractibility, perseverative behavior) alterations.
What does frontal lobe damage cause?
Damage to the neurons or tissue of the frontal lobe can lead to personality changes, difficulty concentrating or planning, and impulsivity.
Which brain region is generally responsible for confabulation?
Confabulation and Reduplicative Paramnesia Impaired memory, poor motivation, and anosognosia are often present. Because many of these associated behaviors are characteristics of frontal lobe disease, confabulation is often linked to frontal lobe damage.
What is the difference between confabulation and delusion?
Delusion is commonly defined as a false belief and associated with psychiatric illness like schizophrenia, whereas confabulation is typically described as a false memory and associated with neurological disorder like amnesia.
What is the most striking feature of frontal lobe syndrome?
Frontal lobe syndrome is due to a broad array of pathologies ranging from trauma to neurodegenerative diseases. The most important clinical feature is the dramatic change in cognitive function such as executive processing, language, attention, and behavior.
