Cognitive Assessments

A precise way to detect subtle cognitive changes

Identify subtle cognitive changes

  • Detect subtle changes early
    Administer this highly sensitive battery of computerized cognition tasks, specifically designed for clinical trials, repeatedly throughout your study to identify changes in cognitive function in any participant population.  
  • Measure major cognitive domains
    Precisely assess working and episodic memory, attention, and executive function tasks relevant in everyday life. 
  • Complete assessments quickly
    Each assessment is brief to complete (thirty minutes or less depending on the content of the battery) thus reducing participant’s testing burden.

Frequently Asked Questions

How are cognitive changes assessed in clinical trial patients?

Cognitive function and changes are assessed using three general approaches: self-report, informant-report, and performance-based measures. Many scales and questionnaires, such as ECog, are commonly used to measure general cognitive function as well as indication-specific cognition, such as ADAS-COG in dementia studies. Other approaches include sensitive computerized clinical assessment batteries designed to detect subtle cognitive changes that can be applied in any trial for any indication.

What is included in a clinical trial cognitive assessment?

While scales and questionnaires vary depending on their purpose, cognitive assessments generally test working memory, episodic memory, attention, tasks, and functions required for everyday life, such as problem-solving and personal care.

What is the purpose of a cognitive test in clinical trials?

Cognitive assessments are used to detect subtle changes in cognitive function, such as impairment or improvements, to determine a treatment’s effect in patients.

Can you assess cognitive deficit, cognitive improvement, or both using the computerized Cognitive Assessments system?

Featuring bidirectional sensitivity, the system can assess potential deficit and improvement in cognition as exemplified by numerous use in Phase I clinical research studies.

What population can this system assess?

Our computerized Cognitive Assessments system is a disease-agnostic tool that can provide cognitive assessment for any type of population, from healthy volunteers and patients with minor cognitive impairment to patients with dementia.

Is there any practice effect associated with the Cognitive Assessments system?

There is little practice effect associated with our cognitive assessments battery. That’s because we use alternate clinical forms at each visit as well as encourage 2 to 4 practice sessions to ensure the patients know how to use the response box and you capture high-quality data.
