Type 2 diabetes mellitus patients showed impaired response selection compared to healthy individuals. This suggests potential motor preparation deficits in well-controlled diabetes without complications.

Area of Science:

  • Neuroscience
  • Clinical Psychology
  • Endocrinology

Background:

  • Type 2 diabetes mellitus (T2DM) is a metabolic disorder with potential neurological implications.
  • Cognitive function, including motor control, may be affected even in well-controlled T2DM.
  • Understanding these effects is crucial for comprehensive patient care.

Purpose of the Study:

  • To compare visual perception, response selection, and response execution between T2DM patients and a matched control group.
  • To identify specific cognitive domains affected by T2DM.
  • To investigate potential motor preparation differences.

Main Methods:

  • A cohort of 10 well-controlled male T2DM patients (mean age 58) without complications was recruited.
  • A control group of 13 age- and IQ-matched healthy male volunteers (mean age 57) was included.

  • Performance was assessed across visual perception, response selection, and response execution tasks.

    • Main Results:

    • No significant differences were observed in visual perception or response execution between the groups.
    • Significant differences emerged specifically in response-selection performance.
    • This indicates that the selection and preparation of motor actions were impaired in T2DM patients.

    Conclusions:

    • Well-controlled Type 2 diabetes mellitus, even without complications, is associated with deficits in response selection.
    • These findings suggest that T2DM may impact the cognitive processes involved in preparing motor actions.
    • Further research is warranted to explore the underlying mechanisms and clinical implications of these motor preparation differences.
