Evaluating depression in cognitively healthy elderly people by using Mini-Mental State Examination

Area of Science:

• Geriatric Psychiatry
• Cognitive Assessment
• Mental Health Screening

Background:

• Depression is a significant concern in the elderly population.
• Accurate and non-invasive screening tools are crucial for early intervention.
• The Mini-Mental State Examination (MMSE) is widely used for cognitive assessment.

Purpose of the Study:

• To evaluate a projective method using the MMSE for depression assessment in cognitively healthy older adults.
• To determine the efficacy of MMSE-based writing analysis in differentiating depressed individuals.

Main Methods:

• Cognitively healthy elderly participants were divided into normal, depressed tendency, and depressed groups.
• All participants completed the Mini-Mental State Examination (MMSE) and the Geriatric Depression Scale (Japanese version).
• MMSE writing analysis focused on sentence calculation, writing content, and figure copying.

Main Results:

• Depressed individuals exhibited higher scores for specific writing characteristics: low calculation scores (0 or 1), superior sentence writing relative to peers, and expression of feelings in writing.
• A scoring system was developed where depressed subjects achieved a score of 2 or higher.
• The method demonstrated high accuracy in differentiating depressed subjects.

Conclusions:

• The developed MMSE-based evaluation method accurately identifies depression in the elderly.
• This approach offers high sensitivity (77.8%) and specificity (76.4%).
• The method is non-intrusive, adding no extra burden to the participants.
