Abstract:
Patients with Mild Cognitive Impairment (MCI) run a higher risk for the development of a dementia. A disturbed awareness of deficits is a symptom of dementia and could be a predictor for the development of dementia in the assessment in the early stages of dementia. This awareness can be assessed by means of the discrepancy between the assessment of memory problems by patient and partner. In this study, the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE-N) was used to assess the level of awareness. The results show that the discrepancy score (the difference between the IQCODE-Nscore of the patient and the IQCODE-Nscore of the partner) was significantly higher for the 61 MCI-patients when compared to the 40 healthy elderly (p = 0,01). This suggests a diminished awareness in MCI-patients. Analysis of the range of the MCI-group shows that this is true for 60% of the patients. Patients with a disturbed awareness score significantly lower on the MMSE (p < 0,01) than patients with an intact awareness.
Insights
Mild Cognitive Impairment (MCI) patients show diminished awareness of their memory deficits, a potential early dementia predictor. This lack of insight was measured using the IQCODE-N, highlighting a key difference from healthy individuals.
Area of Science:
- Neurology
- Psychology
- Gerontology
Context:
- Mild Cognitive Impairment (MCI) is a significant risk factor for dementia.
- Awareness of deficits is a key symptom and potential early predictor of dementia.
- Assessing patient-partner discrepancy in perceived memory problems can reveal awareness levels.
Purpose:
- To investigate awareness of cognitive deficits in MCI patients.
- To determine if awareness of deficits predicts dementia development.
- To utilize the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE-N) to assess awareness.
Summary:
- MCI patients (n=61) exhibited a significantly higher discrepancy score between self and partner assessment of cognitive decline using IQCODE-N compared to healthy controls (n=40).
- This suggests diminished awareness of deficits in a majority (60%) of MCI patients.
- Patients with disturbed awareness scored significantly lower on the Mini-Mental State Examination (MMSE).
Impact:
- Diminished awareness in MCI patients is a quantifiable phenomenon.
- Awareness deficits may serve as an early indicator for dementia progression.
- Findings support the use of awareness assessment in early dementia detection strategies.
