Spanish-language cognitive screening tests: a critical review

Area of Science:

• Neurology
• Geriatrics
• Primary Care Medicine

Background:

• Dementia significantly impacts patients, families, and healthcare systems.
• Existing cognitive impairment screening tools vary in psychometric properties.
• Validated Spanish-language versions of key screening tools are needed.

Purpose of the Study:

• To describe the characteristics of validated Spanish-language versions of the Mini-Cog, Clock-Drawing Test, and Mini-Mental State Examination.
• To provide primary care professionals with information on reliable cognitive screening instruments.

Main Methods:

• A three-stage literature search was conducted on Medline.
• Articles focused on validated, Spanish-language versions of the selected scales.
• Inclusion criteria required data on reliability, validity, sensitivity, and specificity.

Main Results:

• The review assessed the psychometric properties of Spanish-language Mini-Cog, Clock-Drawing Test, and Mini-Mental State Examination.
• Data on reliability, validity, sensitivity, and specificity were analyzed for each tool.
• The characteristics of these validated tools were detailed for clinical application.

Conclusions:

• The Mini-Cog, Clock-Drawing Test, and Mini-Mental State Examination are valuable screening tools for primary care.
• Early identification of mild cognitive impairment and dementia improves patient prognosis.
• These validated Spanish-language tools support timely diagnosis and management.
