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

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:
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 Cognitive Assessment for Parkinson’s Disease Patients (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.
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).

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).
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.

Visual short-term memory is defined as the ability to retain a small amount of visual information (letters, figures, colors ...) for a short period of time. Visual short-term memory appears to be affected in people with Parkinson's disease, however verbal short-term memory remains relatively unaffected. Alterations in visual short-term memory are considered to correspond to the severity of the disease and the motor performance of the user.

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.

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.

Shifting or Mental Flexibility can be defined as the ability of our brain to adapt our behavior and thinking to novel, changing, or unexpected situations. Several studies indicate that people with Parkinson's disease tend to perform worse in cognitive flexibility, which causes a greater number of perseverative errors, which can be detected even early in the disease.

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.
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.
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.
Eye-Hand Coordination Test Fixed Trajectory and Predictable Direction
The Synchronization Test UPDA-SHIF is based on the Vienna Test System (VST) (Whiteside, 2002). In this task the test-taker is required to carefully and precisely track a ball which moves along a path. The distance in pixels between the center of the ball and the cursor moved by the user is considered to calculate the accuracy score.
Multimodal Lexical Memory Test
The Identification Test COM-NAM is based on the Boston Naming Test (Kaplan et al., 1983) and by the vocabulary test from the WAIS-III (Wechsler, 1997). For each object shown, the test-taker must choose from three possibilities: 1) the item is presented for the first time in the task or 2) the last time it appeared the item was spoken or 3) the last time it appeared the item was presented as a picture.
The Inquiry Test REST-COM took as a reference the classic Boston Naming Test (Kaplan et al., 1983), the vocabulary test from WAIS-III (Wechsler, 1997), the Test of Variables of Attention (Greenberg et al., 1996), and the Rey Auditory Verbal Learning Test (Schmidt, 1994). A series of objects are shown. In a new series of objects, the test-taker must then recognize only those objects that were previously displayed. This new series could be presented as images or as spoken words.
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.
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.
The Simultaneity Test DIAT-SHIF stems from the classic Stroop test (Stroop, 1935), the Vienna Test System (Whiteside, 2002), and the Test of Variables of Attention (Greenberg et al., 1996). The test-taker is required to accurately follow a ball moving and turning in all directions on the screen while, at the same time, performing a variant of the Stroop test.
