  • Cognitive Assessment for Parkinson's

  • Explore and discover the areas most affected by Parkinson's Disease.

  • Measure possible cognitive alterations with this test for Parkinson's.


The Cognitive Assessment Battery for Parkinson's (CAB-PK) from CogniFit was designed to help professionals detect, diagnose, and treat Parkinson's Disease. This tool helps provide a complete cognitive screening of the patient and provides a detailed report that allows a trained professional to identify the deficits or alterations associated with Parkinson's. This information can be vital for making a diagnosis, creating an intervention plan, and monitoring the patient's rehabilitation.

The cognitive evaluation is made up of the following tasks:

  • Memory area: Working memory, contextual memory, and short-term memory.

  • Attention area: Focus, updating, and divided attention.
  • Perception area: Visual perception and estimation.
  • Coordination area: Response time.
  • Reasoning area: Planning and processing speed.

Analyzed neuropsychological areas and their relation to Parkinson's

Scientifically based: Validated task batteries

The Parkinson's assessment battery was designed by a group of professional neurologists and psychologists and based on the latest Parkinson's research.

The assessment is made up of a set of tasks created by using visual and auditory stimuli adapted to the characteristics of each user. Each task measure one more cognitive skills. The assessment measures 11 different cognitive skills in its 13 tasks.

Each of the tasks has been scientifically backed and received a score of .8 on the Alpha Crombach statistic measurement.

Every pathology comes with a certain level of cognitive deterioration. These cognitive declines can be seen in the person's daily life. According to CogniFit's studies and scientific literature, Parkinson's is accompanied by both physical and cognitive deterioration. Some of the following cognitive skills may be affected in someone with Parkinson's.


Working Memory and Parkinson's

Working memory is very important for being able to evaluate one's memory capacity. The cause of this decline is closely related to decreased dopamine levels causes most of the cognitive problems related to Parkinson's.

Short-Term Memory and Parkinon's

Memory is also affected in people with Parkinson's. Long and short-term memory may be more or less affected depending on the patient's state and the content that they are trying to remember. For example, it has been shown that information the patient wants and chooses to learn, like a new recipe or how to turn on the new television, will be retained better than, for example, a set of random numbers presented to them. Because of this variation, short-term memory can only measure Parkinson's to a certain extent.

Contextual Memory and Parkinson's

In some cases contextual (or episodic) memory is altered in Parkinson's patients.They may have trouble remember past events that happened in a determined context. The hippocampus is used in contextual memory, which is in charge of forming memories associated to a situation. It is very likely that someone with Parkinson's will have some kind of alteration in their hippocampus.


Focus and Parkinson's

People with Parkinson's have trouble actively paying attention to a stimulus during a prolonged period of time. It is, as we know, important to be able to pay attention to a task while we carry it out, but someone with Parkinson's will get fatigued quickly which also leads to a lack of motivation. This is why we see decreased focus or concentration levels in Parkinson's patients.

Updating and Parkinson's

Updating or mental flexibility may affected by Parkinson's Disease. People with this disease have poor updating skills and have trouble showing flexibility when faced with a situation that is out of their control. Their cognitive rigidity and the impossibility to change strategies to adapt to the situation causes them to develop an obsessive behavior.

Divided Attention and Parkinson's

As we previously mentions, memory is usually altered in Parkinson's patients, and it is often due to lack of attention. This problem, however, also extends to divided attention. It is observed when the patient has to pay attention to different information sources at the same time. These problems may start at the very beginning of the disease, and happen because the patient has a hard time coding two different stimuli at the same time. Because of this, they have trouble dividing their attention and processing two stimuli at the same time.


Visual Perception and Parkinson's

In the first stages of Parkinson's Disease you will be able to see perceptive differences in the patient. Visual perception is one of the cognitive skills most affected by this disease. It causes a loss of ocular sensitivity and a lack of contrast perception. In some cases perception may be affected by alterations in other cognitive skills, like planning or attention, because they work together to strengthen visual perception in a Parkinson's patient.

Estimation and Parkinson's

People with Parkinson's often times have a hard time perceiving time and distance. They have trouble estimating their relative distance from a given stimulus, estimating the speed of an object, and measuring time. This skill is closely related to spatial perception, especially three dimensional vision. Both skills are affected by Parkinson's.


Response Time and Parkinson's

Just like response time, processing speed is also affected in some Parkinson's cases. If processing speed is low, response time will be increased. If they take a long time to understand a question or assimilate information, the time that it takes to respond to a given situation will multiply in some cases. Measuring response time will give an idea of the patient's ability to process information.


Planning and Parkinson's

Planning and everything else that comes with it, like problem solving, goal planning, and strategy modification may be affected by Parkinson's.This may be due to the cognitive rigidity that is common in Parkinson's patients which causes them to have trouble developing new planning and adaptation strategies.

Processing Speed and Parkinson's

Processing speed is altered because it is common for processing speed to be affected and slower in people with Parkinson's. This slow processing speed may be caused by the neurocognitive problems associated with the functions carried out by the frontal lobes. The slowing of processing speed will cause other cognitive skills, like attention, planning, or short-term memory to be affected.

Scientific Documentation

It has been proven that an efficient cognitive assessment requires individuallization and personalization. This is why each one of our Parkinson's tasks adapts to the unique characteristics of each user.

The Parkinson's evaluation system ensures high efficiency by monitoring user results and adjusting tasks in real time.

The results will presented in a report using graphs and images that will represent the user's score for each cognitive skill. In the graphs, you will see the stronger skills in green, the average skills in yellow, and the deficient skills in red. Through these results, the professional will receive quantitative results about the patient's cognitive state. This information will be significant proof to support or refute a possible disgnosis.
