Healthy individuals and those with major depressive episodes exhibit better performance on the Continuous Attention Task (CAT). Deficits in attention tasks may be linked to impaired intellectual functions in psychiatric conditions.

Area of Science:

  • Neuroscience
  • Psychiatry
  • Cognitive Psychology

Background:

  • Attention deficits are common in various psychiatric disorders, impacting daily functioning.
  • The Continuous Attention Task (CAT) is a sensitive measure of sustained attention.
  • Understanding attention differences across disorders is crucial for diagnosis and treatment.

Purpose of the Study:

  • To compare sustained attention abilities using the CAT across patient groups with schizophrenia, schizoaffective disorder, chronic alcohol dependence, and major depressive episodes, as well as healthy controls.
  • To investigate the relationship between attention deficits and intellectual functions in these groups.

Main Methods:

  • Administered the Continuous Attention Task (CAT) to 35 schizophrenic patients, 17 schizoaffective patients, 14 with major depressive episodes, 16 with chronic alcohol dependence, and 31 healthy volunteers.

  • Assessed patients using the Positive and Negative Syndrome Scale (PANSS) and the intelligence test (DMI).

    • Main Results:

    • Healthy subjects and patients with major depressive episodes performed significantly better on the CAT compared to other groups.
    • No significant differences in CAT performance were found between schizophrenic, schizoaffective, and alcohol-dependent patients.
    • Depressive patients showed higher scores on logical multiplication (MN) and analogy (AN) scales of the DMI compared to schizophrenic patients.

    Conclusions:

    • Deficits in Continuous Attention Task (CAT) performance may be associated with impaired intellectual functions.
    • Sustained attention is relatively preserved in major depressive episodes compared to schizophrenia, schizoaffective disorder, and chronic alcohol dependence.
