  • For young adults, adults or seniors
  • The tests lasts about 30-40 minutes
  • Reliability analysis of the evaluation - Only in English Download

CogniFit's Cognitive Assessment Battery for Parkinson's (CAB-PK) is a leading professional tool consisting of a battery of clinical trials and validated tasks, aimed at quickly and accurately detecting and evaluating the presence of symptoms, traits, and dysfunctionalities in the cognitive processes affected by Parkinson's disease.

This innovative online Parkinson's test is a scientific resource that allows you to perform a complete cognitive screening, know the weaknesses and strengths, and assess the risk index of Parkinson's presence as well as know which areas are affected by the disease. This test is aimed at young adults, adults, or seniors who have any of the risk factors. Any private or professional user can easily use this neuropsychological assessment battery.

The report from the assessment will be automatically available for download after the test, which usually lasts about 30-40 minutes.

The diagnosis of Parkinson's Disease (PD) requires multidisciplinary evaluation and a comprehensive differential diagnosis to rule out the possibility that dysfunctional symptoms may be best explained by the presence of a mood disorder, other degenerative diseases, or other pathologies.

Medical history, physical and neurological examination, laboratory analyses, questionnaires, neuroimaging tests and neurophysiological examinations are the most effective tools to diagnose Parkinson's disease, although this is not sufficient to know the degree of cognitive impairment derived from the disease. In order to know the depth of the disorder, a thorough clinical and neuropsychological evaluation is necessary. Note that CogniFit does not directly offer a medical diagnosis of PD. It is recommended to use this comprehensive Parkinson's test in addition to the professional diagnosis and not as a substitute of a clinical consultation

Digitalized Protocol for Parkinson's Assessment (CAB-PK)

Digitalized Protocol for Parkinson's Assessment (CAB-PK)

This comprehensive cognitive screening for Parkinson's Disease consists of a questionnaire and a complete set of neuropsychological testsIt lasts about 30-40 minutes.

Younger adults, adults or seniors at risk for Parkinson's must complete a questionnaire that evaluates symptoms and clinical signs related to Parkinson's disease and then perform a series of validated exercises and tasks that are presented as simple computer games.

Diagnostic Criteria Questionnaire

A series of easy-to-respond questions is presented, aimed at detecting the main diagnostic criteria (DSM-5) and symptoms of Parkinson's disease. The questionnaire contains screening tests.

Neuropsychological factors and cognitive profile

The CAB-PK continues with a battery of tasks aimed at assessing the main neuropsychological factors identified in the scientific literature for this disorder. The results will be compared with the scales according to the age and sex of the user.

Complete results report

At the end of the Parkinson's test, CogniFit generates a fully detailed result report, showing the risk index for the disorder (low-medium-high), the warning signs and symptoms, cognitive profile, analysis of results, and recommendations. The results provide valuable information to identify support strategies.

Psychometric Results

Psychometric Results

CogniFit's Cognitive Parkinson's Test (CAB-PK), uses patented algorithms and artificial intelligence (AI), which makes it possible to analyze thousands of variables and notify users whether there is a risk of Parkinson's with very satisfactory psychometric results.

The neuropsychological cognitive report has a high reliability, consistency, and stability. The test has been validated by repeated tests and measurement processes. Transversal research designs have been followed, like the Alpha Cronbach coefficient, reaching scores of about .9. The Test-Retest tests have received scores of almost 1, which shows the high reliability and precision that this battery offers.

When should you use this Parkinson test?

When should you use this Parkinson test?

With this assessment battery, it is possible to reliably detect the risk of Parkinson's-related symptoms and cognitive impairment in young adults, adults or seniors. Early detection allows for treatment commencement and an appropriate cognitive stimulation program to help maintain impaired cognitive abilities in Parkinson's disease at a functional level.

This neuropsychological assessment battery also identifies the risk of early onset Parkinson's and associated cognitive impairment in younger people. Although early-onset Parkinson's (diagnosed before age 49) is estimated to account for only 10% of all Parkinson's patients, it should be noted that thousands of young people remain affected. Functional and cognitive impairment may not yet be evident at those ages, but it is best to begin stimulating cognitive abilities as soon as possible in order to minimize impairment.

Without early detection and the necessary adapted tools, it is difficult to function on a daily basis and can lead to problems in the workplace, in social or family interactions and emotionally. Therefore, this disease not only causes resting tremors but also affects different cognitive aspects: attention and memory problems, visuospatial alterations, slow processing, executive and language dysfunction. Parkinson's is associated with delays and difficulties in functional, work and social functioning. Mainly it is possible to differentiate between:

Parkinson's Cases
Most representative symptoms
According to type of difficulties
Difficulties in movement and mobility
Language difficulties
Sleep difficulties
Psychological problems

Difficulties in movement and mobility

The most well known and obvious symptoms are the visible motor alterations in Parkinson's disease. Tremor, stiffness, slowness, and postural instability can make the patient's day-to-day life much more difficult. For example, slowness may prevent the patient from reacting in time when cooking or simply moving from one room to another can be a difficult activity.

Language difficulties

Most people affected by Parkinson's disease experience changes in speech and voice. They also end up with swallowing problems with the progression of the disease. Symptoms that appear in the rest of the body (tremors, stiffness, and slowness) may also occur in the muscles responsible for speech and swallowing. Therefore, the person with Parkinson's may need more time to answer a question, or choking may occur when food textures are mixed.

Sleep difficulties

About 33% of patients with Parkinson's disease have insomnia, as sleep disorders are common in this disease. Other common sleep disorders in Parkinson's are vivid dreams, daytime sleepiness, or disturbances in the sleep-wake cycle. This can lead to a person with Parkinson's being tired during the day and having trouble going to sleep at night.

Psychological problems

There is a group of non-motor symptoms in people with Parkinson's, such as depression, anxiety, or apathy. They may experience hallucinations, delusions, loss of impulse control, and end up manifesting inappropriate behaviors. For this reason, it is not uncommon for Parkinson's patients to also show sadness and lack interest in activities they have always liked.

Description of the diagnostic criteria questionnaire

Description of the diagnostic criteria questionnaire

Parkinson's is characterized by a series of symptoms and clinical signs. These indicators may make us suspect the presence of this disorder. Therefore, the first step of the Parkinson's cognitive assessment battery (CAB-PK) consists of a questionnaire with screening questions that are adapted to the main diagnostic criteria and symptoms appropriate to each age group.

The questions presented here are similar to those that can be found in a diagnostic manual, clinical questionnaire or assessment scales but have been simplified so that they can be understood and answered by virtually anyone.

Diagnostic criteria in adults

It is made up of a series of simple questions that can be completed by the user him or herself, or by the professional in charge of the assessment. The questionnaire gathers questions about the following areas:Motricity and movement (slowness, postural instability, tremors, stiffness, etc.), mental state (depression, anxiety, apathy, etc.), sleep (insomnia, daytime sleepiness, vivid dreams, disturbances of the sleep-wake cycle, etc.) and language (changes in speech, voice, swallowing problems).

Battery description to assess neuropsychological factors involved in Parkinson's disease

Battery description to assess neuropsychological factors involved in Parkinson's disease

The presence of alterations in some of the cognitive abilities may be an indicator of Parkinson's. An overall profile of cognitive abilities can tell us how intense is the extent of cognitive impairment derived from this disease.

Some of the problems in mental state, sleep, language, and motor skills can be caused by deficits in cognitive abilities. These are the domains and cognitive skills assessed in the Parkinson's Test (CAB-PK).

Evaluated Cognitive Domains
Cognitive Abilities


Ability to filter distractions and focus on relevant information.


8.3% above average

Divided Attention

Divided attention and Parkinson's. Divided attention is the ability to attend to different stimuli or tasks at the same time. People with Parkinson's may have problems managing their attentional resources when there is a high task demand. For this reason, a person with Parkinson's may have problems while driving, for example.

655Your Score


Focused Attention

Focus and Parkinson's. Focus is the ability to concentrate our attention on an objective stimulus, regardless of how long it lasts. Often, people with Parkinson's have difficulty focusing on the relevant and appropriate stimuli or events of each situation. People with Parkinson's have a hard time in a conversation since they are prone to lose information.

563Your Score



Updating and Parkinson's. Updating is the ability to oversee actions and behavior as you carry out a task to ensure that it is being completed according to the plan of action. These patients may have cognitive problems in updating their own behavior, especially when the feedback from the task is less evident, such as, for example, they may have difficulty proving that they are overtaking the car correctly.

483Your Score



Ability to retain or manipulate new information and recover memories from the past.


8.1% above average

Contextual Memory

Contextual memory and Parkinson's. Contextual memory is the ability to memorize and discriminate the actual source of a specific memory. People with this disease may have trouble remembering who said a particular phrase or where they read a news story, for example.

474Your Score


Short-Term Memory

Short-term memory and Parkinson's. Short-term memory is the ability to hold a small amount of information for a short period of time. Parkinson's disease may, for example, make it difficult or impossible to understand read information.

628Your Score


Working Memory

Working memory and Parkinson's. Working memory is the ability to retain and manipulate information needed for complex cognitive tasks, such as understanding language, learning, and reasoning. A deficit in Parkinson's-related work memory may mean difficulty understanding written language, spoken language, or working with received information.

533Your Score



Ability to efficiently carry-out precise and organized movements.


7.6% above average

Response Time

Reaction time and Parkinson's. The reaction time refers to the time that elapses from when we perceive something until we respond to that stimulus. One of the main motor disorders that appear in Parkinson's disease is bradykinesia or slow movement. Therefore, the reaction time of people with Parkinson's may be slower for physical activities, such as eating or getting dressed.

700Your Score



Ability to interpret the stimuli from one's surroundings.


8.4% above average


Estimation and Parkinson's. Estimation is the ability to predict or generate an answer when the solution is not available. Parkinson's disease can alter this ability, resulting in problems interacting with the environment (estimating distance) or organizing (estimating time).

518Your Score


Visual Perception

Visual perception and Parkinson's. Visual perception is the ability to interpret the information that our eyes give us about the environment. The subcortical structures affected in Parkinson's are also involved in visual perception. This makes it difficult for people with Parkinson's to interpret this visual information.

454Your Score



Ability to efficiently use (organize, relate, etc.) acquired information.


7.7% above average


Planning and Parkinson's. Planning is the ability to organize mentally the best way to achieve a goal in the future. People with Parkinson's usually have planning alterations, which can lead to problems with sequencing actions, such as planning what ingredients you will need to fill a recipe correctly.

680Your Score


Processing Speed

Processing speed and Parkinson's. Processing Speed is the time a person needs to perform a mental task. In Parkinson's disease, not only is there a slow movement, but the speed of mental processing is also slow. This means that a person with Parkinson's may need more time to remember information or to solve a problem.

564Your Score


Evaluation tasks

Evaluation tasks

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

Speed Exploration Test REST-HECOOR

This exercise has been inspired by the classic test of Variables of Attention (TOVA) and the classic Hooper Visual Organisation Task (VOT) test by Hooper. The Speed Exploration Test REST-HECOOR is a professional instrument designed to explore processing speed and reaction time skills.

Sequencing Test WOM-ASM

The Sequencing Test WOM-ASM was based on Conners' classic test (CPT) and the Wecshler Memory Scale (WMS) test of direct and indirect digits. Using these tests, we are able to observe the temporary storage capacity and, above all, the capacity to manipulate information to perform higher cognitive tasks, such as language comprehension or reasoning.

Identification Test COM-NAM

The COM-NAM Identification test is based on the classic NEPSY and TOMM tests. With this test, the level of channeling and classification of stimuli in memory is observed. In addition, it allows the ability to observe how the user detects and reacts as fast as possible.

Decoding Test VIPER-NAM

This evaluation task integrates notions of the classic Korkman, Kirk and Kemp test of 1998 (NEPSY). It measures the naming capacity, response time and processing speed, measuring the number of cognitive resources that the user allocates to the exercise of decoding, recognizing and understanding stimuli in an efficient way.

The Brain and Parkinson's Disease

The Brain and Parkinson's Disease

Not only do people with Parkinson's have motor tremors and difficulties, but the brain alterations resulting from the disease also have negative cognitive consequences. The brain areas that are mainly altered in Parkinson's disease are the Substantia Nigra and, consequently, the Basal Ganglia.

1 Substantia Nigra

Substantia Nigra or black substance is a set of dopaminergic neurons (which produce the neurotransmitter "dopamine") pigmented by an element called "neuromelanin", which gives it a blackish color. The dopaminergic axons of these neurons connect with other nuclei of the basal ganglia. In Parkinson's disease, the neurons of the black substance are destroyed, which disrupts or makes it difficult to connect dopamine between the black substance and the basal ganglia.

2 Basal Ganglia

Basal ganglia are a set of subcortical structures located at the "base" of the brain. The main function of the basal ganglia is to regulate voluntary movement and to learn motor skills. Dopamine is a fundamental neurotransmitter in the correct functioning of the basal ganglia. With the death of dopaminergic neurons of the black substance, basal ganglia act erratically, producing Parkinson's symptoms such as the stiffness and slowness of movement, in addition to certain cognitive symptoms.

Great test for my dad (with Parkinson's). We were able to see which areas he needs to work on



i was just diagnosed with parkinson's



My report said I should talk to a doctor because there were "conflicting results"??



It says i don't have parkinson's because of some exclusion criteria, so i have to go back to my doctor. i don't really get it, but i guess i'll talk to my doctor



Interesting and useful to see the cognitive deterioration caused by Parkinson's. This will be a welcomed addition to my practice

Dalia S


Really comprehensive report, especially on a cognitive level.



I use this with my patients to get a better idea of their cognitive health. I've been happy with the service and products that we've been using.



its sad that people have parkinsons we have to know why it happens



Interesting for clinics or practices that focus on neurorehabilitation

Ben A.D


Some of my older patients aren't used to using computers and had a hard time using the mouse, but other patients enjoyed it. We got some really good information that I've been using to apply to their intervention.



My mom isn't used to using a computer and should have done it on the iPad, but we didn't know that was an option. I want her to take it again but we have to buy a new assessment.
