Agreement between Computerized and Human Assessment of Performance on the Ruff Figural Fluency Test.

The Ruff Figural Fluency Test (RFFT) is a sensitive test for nonverbal fluency suitable for all age groups. However, assessment of performance on the RFFT is time-consuming and may be affected by interrater differences. Therefore, we developed computer software specifically designed to analyze performance on the RFFT by automated pattern recognition.

Longitudinal study of performance on the Ruff Figural Fluency Test in persons aged 35 years or older.

The Ruff Figural Fluency Test (RFFT) is a cognitive test to measure executive function. Longitudinal studies have shown that repeated testing improves performance on the RFFT. Such a practice effect may hinder the interpretation of test results in a clinical setting.

Statin use and cognitive function: population-based observational study with long-term follow-up.

We aimed to evaluate the association between statin use and cognitive function. Cognitive function was measured with the Ruff Figural Fluency Test (RFFT; worst score, 0; best score, 175 points) and the Visual Association Test (VAT; low performance, 0-10; high performance, 11-12 points) in an observational study that included 4,095 community-dwelling participants aged 35-82 years. Data on statin use were obtained from a computerized pharmacy database.

The interaction of age and type 2 diabetes on executive function and memory in persons aged 35 years or older.

It is generally assumed that type 2 diabetes increases the risk of cognitive dysfunction in old age. As type 2 diabetes is frequently diagnosed before the age of 50, diabetes-related cognitive dysfunction may also occur before the age of 50. Therefore, we investigated the association of type 2 diabetes with cognitive function in people aged 35-82 years.

Cardiovascular risk profile and cognitive function in young, middle-aged, and elderly subjects.

Background And Purpose: Cognitive decline occurs earlier than previously realized and is already evident at the age of 45. Because cardiovascular risk factors are established risk factors for cognitive decline in old age, we investigated whether cardiovascular risk factors are also associated with cognitive decline in young and middle-aged groups.

Methods: The cross-sectional study included 3778 participants aged 35 to 82 years (mean age, 54 years) and free of cardiovascular disease and stroke.
