- Abstract
- Background
and Objective : Several recent studies have demonstrated that cognitive function is impaired in non-insulin dependent diabetes mellitus (NIDDM) patients compared with age-matched non-diabetic controls. However, the underlying pathophysiological mechanism of this diabetic central nervous involvement remains obscure. The present study was designed to explore further whether cognitive deficits are present in NIIDDM patients who do not show apparent symptoms and signs of central nervous system damage and to evaluate the influence of clinical parameters and diabetic complications on cognitive function. Methods : Thirty patients over 50 years of age with NIDDM and 30 age-, sex- and education-matched normal controls were recruited for the study. P300 event-related potential test and neuropsychological tests (Mini-Mental State Examination, MMSE; Benton Visual Retention test; Digit Span Forward and Backward) were perfomed. P300 latencies were recorded according to the conventional technique using Counterpointer MK2.
Results
: Compared with controls, NIDDM patients showed significant impairment in
MMSE (P<0.05), Benton Visual Retention (P<0.05), and Digit Span Backward (PConclusions
: This study suggest that 1) cognitive function is decreased in NIDDM
patients who do not show apparent symptoms and signs of central nervous system
damage, 2) P300 latency may reveal cognitive changes not detected by
nouropsychological tests, and 3) P300 event-related potentials, MMSE, Benton Visual
Retention and Digit Span Backward tests may be included in a battery of cognitive
function tests in NIDDM patients.
