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)

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).

What cognitive skills are assessed with this Chemo Brain test?

What cognitive skills are assessed with this Chemo Brain test?

The presence of alterations in some cognitive skills may be an indicator of Chemo Brain. A general profile of the cognitive skills may help you understand the severity of the cognitive alterations caused by this disorder.

Short-Term Memory

Short-term memory and Chemo Brain. Short-term memory is the ability to hold onto a small amount of information over a short period of time, like when we remember the beginning of a sentence in order to make sense of the sentence as a whole. A problem in short-term memory may alter one's ability to understand what they hear or impede their ability to correctly understand the information that they receive. According to research, cancer patients have noticed an alteration in their short-term memory after treatment.

Processing Speed

Processing speed can be defined as the time it takes a person to do a mental task. That is, the processing speed is the time it takes between when the stimulus is received and a response is emitted. Processing speed is one of the most commonly reported capabilities in chemotherapy-related cognitive dysfunction, since people who have undergone type of treatment tests usually require a greater amount of time to process the information than healthy people.

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.

Tapping Test

The Speed Test REST-HECOOR exercise was inspired by the classic test of Fingertip tapping from the assessment battery NEPSY (Korkman et al., 1998). The test-taker is required to keep on clicking for 10 seconds and as rapidly as possible with the mouse, or finger if using a touch-screen device, in a defined area on the screen. Data is collected as the number of clicks during the allocated time, number of clicks inside the defined area and number of clicks outside it.

Psychomotor Vigilance Test

The Resolution Test REST-SPER was inspired by the classic paradigms Go/No Go Task (Gordon & Caramazza, 1982), Continuous Performance Test (Conners, 1989; Epstein et al., 2001), and the Psychomotor Vigilance Task (Dinges & Powell, 1985). The test-taker is required to rapidly press on circles which appear on the screen and to ignore hexagons should they also appear. Embedded in the task are 16 circles-only items and 8 circles-and-hexagons items. For each item data is collected on response time, response accuracy and cursor distance from target center.

Visual Working Memory Span Test

The Concentration Test VISMEM-PLAN took as a reference the Corsi block-tapping test (Corsi, 1972; Kessels et al., 2000; Wechsler, 1945). In the first part of the task, some circles, within a fixed array of circles, light up. The test-taker is required to memorize which circles, within the array, have lit up and then try to reproduce the sequence in the right order. In the second part of the task, a delay of 4 secs is added between the first screen and the playback screen, in order to increase the time the user must retain the information.

Digit Span Test

The Sequencing Test WOM-ASM is based on the classic direct and indirect digit test of the WAIS-III (Wechsler, 1997). The test-taker is required to remember and reproduce increasingly longer number sequences, which appear, each in its turn, on the screen. The task will begin with a two- -number sequence.

Visual Memory Test

The Recognition Test WOM-REST is based on the classic tests of Symbol search (WAIS) (Wechsler, 1997), Wisconsin Card Sorting Test (WCST) (Heaton, 1981) and Raven's Progressive Matrices Test (Raven, 1936). In this task, a trio-sequence of objects is presented in the center of the screen. The test-taker is required to memorize these stimuli in a first screen, and to recognize it from among four trio-sequences in a second screen. The number of correct answers is considered to calculate an accuracy percentage.

Number-Size Congruency Test

The Processing Test REST-INH was inspired by the classic Stroop test (Stroop, 1935). The test-taker is required to press on the larger of two circles, regardless of the number inscribed in each circle, while ignoring the text that could appear on the top-middle part of the screen. They are then required to press on the higher number regardless of the size of the circle in which the number is inscribed.

Stroop Test

The Equivalencies Test INH-REST was based on the classic Stroop test (Stroop, 1935). The test-taker is asked to press on the spacebar (go action) only if the color names on the screen are printed in the matching color and to refrain from pressing (no-go) if the color of the letters does not match the printed color name.

Naming Test

The Decoding Test VIPER-NAM was inspired by the Boston Naming Test (Kaplan et al., 1983) and by the vocabulary test from the WAIS-III (Wechsler, 1997). The test-taker is required to click on the first letter, among four of them, that spells the name of the object depicted on the screen. For example, for the picture of an apple, the test-taker should click on the letter “A” but not on the three incorrect responses (C, P, M) also present on the screen.

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.
