Cognitive Function Assessment Skill

Manages cognitive function assessment for the elderly, including MMSE, MoCA tests, cognitive domain evaluation, and daily function assessment.

Core Flow

User Input -> Identify Operation Type -> Extract Parameter Info -> Check Completeness -> [Need Supplement] Ask User
                                                      |
                                                   [Information Complete]
                                                      |
                                              Generate JSON -> Save Data -> Output Confirmation

Step 1: Parse User Input

Operation Type Recognition

Cognitive Domain Keywords Mapping

Function Status Keywords Mapping

ADL Item Keywords

IADL Item Keywords

Step 2: Check Information Completeness

MMSE Test Required:

• Total score (0-30 points)

MoCA Test Required:

• Total score (0-30 points)
• Education level (optional, for score adjustment)

Cognitive Domain Assessment Required:

• Domain name (memory/executive/language/visuospatial)
• Function status (normal/mild_impairment/moderate_impairment/severe_impairment)

ADL/IADL Assessment Required:

• Item name
• Function status

Step 3: Interactive Prompts (If Needed)

Scenario A: Missing MMSE/MoCA Score

Please provide test total score (0-30 points)

Scenario B: Missing Cognitive Domain Assessment Information

Please specify the cognitive domain to assess:
- memory (memory)
- executive (executive function)
- language (language ability)
- visuospatial (visuospatial ability)

What is the function status?
- normal (normal)
- mild_impairment (mild impairment)
- moderate_impairment (moderate impairment)
- severe_impairment (severe impairment)

Scenario C: Missing ADL/IADL Items

Please provide specific activity items and function status

Step 4: Generate JSON

MMSE Test Record

  "test_type": "mmse",
  "date": "2025-06-20",
  "total_score": 27,
  "max_score": 30,
  "interpretation": "Normal",
  "items": {
    "orientation": 10,
    "registration": 3,
    "attention": 5,
    "recall": 3,
    "language": 6
  }
}

MoCA Test Record

{
  "test_type": "moca",
  "date": "2025-06-20",
  "total_score": 24,
  "adjusted_score": 25,
  "education_years": 12,
  "max_score": 30,
  "interpretation": "Mild Cognitive Impairment"
}

Cognitive Domain Assessment Record

{
  "domain": "memory",
  "status": "mild_impairment",
  "assessment_date": "2025-06-20",
  "notes": "Short-term memory impaired, long-term memory preserved"
}

ADL Assessment Record

{
  "activity": "bathing",
  "status": "independent",
  "assessment_date": "2025-06-20"
}

Complete schema definition: see schema.json.

Step 5: Save Data

1. Read data/cognitive-assessment.json
2. Update corresponding sections based on operation type
3. Update statistics
4. Write back to file

Execution Instructions

1. Identify operation type (mmse/moca/domain/adl/iadl/status/trend/risk)
2. Extract parameter information (scores, cognitive domains, function status, etc.)
3. Check required field completeness
4. If missing, ask user to supplement
5. Generate JSON compliant with schema.json
6. Save to data/cognitive-assessment.json
7. Output confirmation and interpretation results

Example Interactions

Example 1: MMSE Test

User: mmse score 27

AI: MMSE test result recorded
Total score: 27/30
Interpretation: Normal
Next assessment: 2026-06-20

Example 2: Cognitive Domain Assessment

User: domain memory mild_impairment

AI: Cognitive domain assessment recorded
Cognitive domain: Memory (memory)
Status: Mild impairment (mild_impairment)

Currently impaired cognitive domain: Memory

Example 3: ADL Assessment

User: adl independent

AI: ADL assessment result recorded
All 6 basic activities: Independent

Medical Safety Boundaries

Cannot Do:

• Diagnose cognitive impairment or dementia
• Replace neurologist/geriatrician professional assessment
• Provide specific medication treatment plans

Can Do:

• Cognitive function screening (MMSE/MoCA)
• Cognitive decline trend tracking
• Activities of daily living assessment (ADL/IADL)
• Cognitive domain function assessment
• Risk warning and medical visit recommendations

Medical Visit Recommendations:

Seek medical attention if:

• MMSE <= 26 points
• MoCA <= 25 points
• Multiple cognitive domains impaired
• ADL/IADL function decline
• Rapid cognitive decline
