Dysexecutive Syndrome - Comorbid Disorders With DES

Comorbid Disorders With DES

DES often occurs with other disorders, which is known as comorbidity. Many studies have examined the presence of DES in patients with schizophrenia. Results of schizophrenic patients on the Behavioural Assessment of the Dysexecutive Syndrome (BADS) test (discussed below) are comparable to brain injured patients. Further, results of BADS have been shown to correlate with phases of schizophrenia. Patients in the chronic phase of the disorder have significantly lower scores than those who are acute. This is logical due to the similarities in executive disruptions that make everyday life difficult for those with schizophrenia and symptoms that form DES.

Patients with Alzheimer's disease have been shown to exhibit impairment in executive functioning as well. The effects of DES symptoms on the executive functions and working memory, such as attentiveness, planning and remembering recently learned things, are some of the earliest indicators of Alzheimer's.

Studies have also indicated that chronic alcoholism (see Korsakoff's syndrome) can lead to a mild form of DES according to results of BADS.

Famous quotes containing the words disorders and/or des:

    It no longer makes sense to speak of “feeding problems” or “sleep problems” or “negative behavior” is if they were distinct categories, but to speak of “problems of development” and to search for the meaning of feeding and sleep disturbances or behavior disorders in the developmental phase which has produced them.
    Selma H. Fraiberg (20th century)

    When I was growing up I used to think that the best thing about coming from Des Moines was that it meant you didn’t come from anywhere else in Iowa. By Iowa standards, Des Moines is a mecca of cosmopolitanism, a dynamic hub of wealth and education, where people wear three-piece suits and dark socks, often simultaneously.
    Bill Bryson (b. 1951)
