    Summary

    This study adapted the London Towers Test for assessing cognitive abilities in dementia patients. Normative data revealed age impacts problem-solving skills, but education and sex do not significantly influence performance.

    Area of Science:

    • Neuropsychology
    • Cognitive Assessment
    • Dementia Diagnostics

    Background:

    • Shallice's London Towers Test is a non-verbal problem-solving task.
    • Existing assessments may not be suitable for demented patients.
    • Need for normative data on cognitive abilities across demographics.

    Purpose of the Study:

    • To obtain normative data for a simplified London Towers Test.
    • To evaluate the test's suitability for diagnosing dementia syndromes.
    • To investigate the influence of age, education, and sex on performance.

    Main Methods:

    • Administered a simplified, non-verbal problem-solving task (London Towers Test variant) to 131 healthy adults.
    • Collected data on age, education, and sex.
    • Analyzed performance to establish normative values and identify influencing factors.

    Main Results:

    • A significant age-related decline in problem-solving performance was observed in normal subjects.
    • Education and sex did not show a significant impact on test performance.
    • The simplified test demonstrated ease of administration and a wide score distribution, suitable for dementia assessment.

    Conclusions:

    • The simplified London Towers Test provides valuable normative data, accounting for age.
    • This tool can aid in the neuropsychological diagnosis of demential syndromes by assessing cognitive function.
    • The test is ready for clinical use to evaluate cognitive abilities in relation to age.
