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.

Working Memory

Working memory and Chemo Brain. After cancer treatment, patients often mention a decline in their working memory, which is the ability to use the information necessary to carry out complex cognitive tasks, like comprehension, learning, and reasoning. A poor working memory may cause difficulty remembering appointments or turning off the lights when leaving the house. The neurotoxicity of the medications used in oncological processes, stress, and anxiety may cause this decline in working memory.

Evaluation tasks

Evaluation tasks

This multi-dimensional scientific resource uses multiple evaluation tasks. Here you can see examples:

Processing Test REST-INH

The Processing Test REST-INH was inspired by the classic Variables of Attention (TOVA) test.The task helps to perceive, process, and respond to a stimulus. Depending on the processing speed, the response time will be affected to a greater or lesser extent. It will also allow the user to ignore irrelevant or unimportant stimuli.

Recognition Test WOM-REST

The Recognition Test WOM-REST is based on the Continuous Performance Test (CTP), the Test of Memory Malingering (TOMM), the Visual Organization Task (VOT), and the Test of Variables of Attention (TOVA). The task will help evaluate the user's executive functions and understand which are their strengths and weaknesses when organizing and acting depending on the stimulus.

Equivalencies Test INH-REST

The Equivalencies Test INH-REST is based on Stroop's classic test. This test evaluates the user's capacity to discern between two tasks as the same time, focusing on the main task and ignoring the less important ones. This task will help activate two parts of the brain at the same time, developing both parts that are used in the process. As the user will have to attend to more than one stimuli at a time, the test will require concentration and focus.

Concentration Test VISMEN-PLAN

This evaluation task is inspired by the Wechsler Memory Scale (WMS) direct and indirect digits test, the classic Memory Malingering Test (TOMM) and the classic Tower of London Test (TOL), allowing to measure planning capacity, visual memory, short-term memory, response time, working memory and processing speed, among others.

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.
