What is the CogniFit Chemo Brain Test?

What is the CogniFit Chemo Brain Test?

  • Evaluate the risk index of the presence of Chemo Brain
  • For adults of all ages
  • Takes about 30-40 minutes to complete
  • Reliability analysis of the evaluation - Only in English Download

The Cognitive Assessment for Chemo Fog Patients (CAB-CF) from CogniFit is a leading professional test that uses clinical and validated tasks designed to quickly and accurately detect the presence of symptoms, traits, or dysfunctions in the cognitive processes affected by cancer treatment.

This innovative Chemo Brain test is a scientific resource that makes it possible to take a complete cognitive screening, understand cognitive strengths and weaknesses, and evaluate the risk index for the presence of Chemo Brain (or Chemo Fog). This test is suitable for people 18 years and older, like young adults, adults, or seniors who have undergone cancer treatment and may present related cognitive decline. Anyone can easily use this neuropsychological assessment battery. The results of this assessment will automatically be available after completing the test, which usually lasts about 30-40 minutes.

Cancer is one of the most devastating diseases that we have today, and the treatments for it can be aggressive for the patient. These treatment processes can noticeably weaken different cognitive skills, affecting daily life. The detection of this cognitive deterioration is an important part of the intervention and correction of this cognitive decline, and the earlier that you work to improve the skills, the better chance there is of recovering cognitive function and independence.

A clinical consultation and history, questionnaires, clinical evaluation scales, and clinical test are all effective tools for detecting certain cognitive problems, but they are able to detect the degree to which these cognitive skills are affected. A clinically validated neuropsychological assessment can help perform an exhaustive assessment of the different cognitive functions affected by cancer treatments. Note that CogniFit does not directly offer a medical diagnosis of chemo fog but the neuropsychological assessment can help perform a screening of different cognitive functions. We recommend using this Chemo Brain test to complement a professional assessment, and never to replace a clinical consultation.

Phases of this Chemo Brain Test (CAB-CF)

Phases of this Chemo Brain Test (CAB-CF)

This complete cognitive evaluation to detect Chemo Fog and Chemo Brain are made up of a questionnaire and a complete battery of neuropsychological tests. It usually takes about 30-40 minutes to complete.

Any adult who has undergone chemotherapy treatment will answer the questionnaire in order to evaluate the clinical signs and symptoms related to these cognitive alterations. After the questionnaire, a series of validated tasks presented as online games will appear on the screen for the user to complete.

Well-being Questionnaire

A series of simple questions designed to detect the main symptoms of Mental Fog will be presented. This questionnaire is an evaluation tool adapted to the effects of Chemo Brain.

Neuropsychological factors and cognitive profile

The CAB-CF continues with a battery of tasks aimed at evaluating the main neuropsychological factors identified in the scientific literature surrounding this disorder. The results will be compared to other users of the same age and gender.

Complete results report

After completing the Chemo Brain test, a detailed report will be available to download, where the user's risk index for Mental Fog will appear, along with a description of the warning signs, cognitive profile, and results analysis, and recommendations. These results offer valuable information to help create an appropriate support strategy.

Psychometric Results

Psychometric Results

The Cognitive Assessment for Chemo Fog Patients (CAB-CF) from CogniFit uses patented algorithms and artificial intelligence (AI) that makes it possible to analyze thousands of variables and highlight any risk of Mental Fog with very satisfactory psychometric results.

The cognitive profile in the neuropsychological report has received high reliability, consistency, and stability ratings. The test has been validated through repeated tests and measurement processes. Transversal research designed, like the Cronbach Alpha have been followed, reaching scores of about .9, and the Test-Retest tests received scores of almost 1, which shows the high level of reliability and precision.

Symptoms of Chemo Brain

This term is used to describe the changes in memory, attention, and concentration, and the ability to do different mental tasks that are related to chemo or hormone therapy treatment for cancer. Other factors aside from medication can also play a role in these cognitive deficits, like age, gender, and the type of cancer.

Emotional Symptoms

A cancer diagnosis and its progression can cause considerable psychological distress and patients and their families. Studies show that between 25% and 50% of patients diagnosed with cancer will experience varying levels of emotional distress. Recent studies have shown that there is a higher presence of depression, anxiety, and emotional distress in cancer patients than the general population.

Physical Symptoms

Both the treatment and the disease itself can cause physical, digestive, metabolic, motor and sleep changes, as well as an alteration in how one sees their self-image. These changes may have a lesser or greater effect on the patient.

Description of the diagnostic criteria questionnaire

Description of the diagnostic criteria questionnaire

Mental Fog or Chemo Brain is characterized by a series of clinical symptoms. These indicators can help better understand the presence of this disorder, which is why the first part of the Cognitive Assessment for Chemo Fog Patients (CAB-CF) is a questionnaire that adapts to the main diagnostic symptoms of Chemo Fog for each age range.

The questions in this questionnaire are similar to what one may find in a diagnostic manual, clinical questionnaire, or scales for Chemo Fog. However, the questions have been simplified to be easily understood by any user.

Diagnostic Criteria for Chemo Brain for Adults and Seniors

Made up of a series of simple questions that can be completed by the professional responsible for the assessment or the person taking the Chemo Brain test. The questionnaire covers the following domains: Emotional symptoms (psychological distress, like anxiety or depression), Physical symptoms (changes in self-image, metabolic changes, sleep changes, fatigue, muscle pain, etc.), and Chemo Fog symptoms (problems with different cognitive skills, like memory or attention).

Evaluation tasks

Our Digital Cognitive Assessments

CogniFit digital tests are designed to measure a specific areas of cognition and are grouped together to form customized batteries based on the unique requirements of the study design and population. Learn more about our different tests and how they can support the unique needs of your study by exploring the details and demos below.

Verbal Fluency Test

The CogniFit Verbal Fluency Test is a digitized replica of the classic F-A-S task (Spreen & Benton, 1977). This task will allow to know the user's verbal fluency, i.e. the ability to evoke valid and distinct exemplars of a particular category. This task requires a device with a microphone and permissions to use it.

Visual Episodic Memory Test MemTrax

The CogniFit Visual Episodic Memory Test is a version of the Memtrax memory assessment task (Ashford, 2005). This task seeks to measure episodic memory through items of a visual nature, identifying only whether the displayed image has been previously displayed or not.

Selective Attention Test

The CogniFit Selective Attention Test is based on the classic d2 Test (Brickenkamp, 1962). This task is specifically aimed at measuring the user's selective attention.

Simplified Eriksen's Flanker Test

The CogniFit's Simplified Eriksen's Flanker Test is a shorter digitized replica of the task of the same name (Eriksen and Eriksen, 1974). This task seeks to measure how much interference is generated by the presentation of adjacent incongruent and irrelevant visual information, but avoiding the neutral trials. The difference in reaction time between incongruent and congruent trials responded to correctly is what is known as the Flankers Effect.

Eye-Hand Coordination Test Multidirectional and Unpredictable Direction

The Coordination Test HECOOR was inspired by the classic Trail Making Test (Reitan, 1955), and by the Vienna Test System (Whiteside, 2002). The test-taker is required to track, with the mouse (or on-screen digital joystick, if using a mobile device), a ball moving in an undetermined itinerary.

Visual Search Test

The Exploration Test SCAVI-REST was inspired by the Hooper Visual Organization Task (VOT) test by Hooper (1983). This cognitive assessment is responsible for measuring visual scanning and response time in order to find a stimulus that is surrounded by other, less important stimuli. Initially, it requires an investigation of the context on a general level, in order to later perform a more specific scan.

Chemo Fog and The Brain

Chemo Fog and The Brain

The cognitive problems related to Mental Fog or Chemo Brain are based on determined brain alterations. Unlike other disorders, the specific brain areas affected by Chemo Fog have not been identified, but rather, damage to the brain on the whole. This is why a general division makes it possible to distinguish between the alterations in the gray matter (neural nuclei) and white matter (neural axons). Few studies have been conducted with respect to the effect that certain drugs used in cancer treatments may cause, but there are some robust conclusions.

  • Difficulty concentration and thinking clearly
  • Problems multi-tasking (doing multiple things at the same time)
  • Problems remembering words during a conversation
  • Slower processing speed when learning new things
  • Difficulty concentrating
  • Difficulty organizing oneself or feeling mentally "fuzzy"

Because of this symptomology, we can infer that some of the brain structures affected are:

1 Prefrontal Lobe

Is in charge of planning behavior and attending to various stimuli at the same time, remembering recent events, concentration, and structuring thought.

2 White Matter

White matter refers to the set of neural axons. These axons work to connect and help neurons communicate between each other, which means that the information received from one side of the brain can be transmitted to another neuron (or set of neurons) on the other side. Chemotherapy may produce a diffusion in the transmission of information from one neuron to another, which may cause slower processing speed and response time, making it more difficult to carry out daily activities.
