How COGNISION® Helps Physicians Help Patients

Is it dementia or depression? Is the patient ready to return to their environment post head injury? COGNISION® helps physicians answer these questions and more by objectively measuring cognitive deficits and providing physicians with the clarity they need to better care for their patients.

How It Works

By placing the device headset on the surface of the scalp, COGNISION® measures electrical activity in the brain responsible for cognitive function. The device rapidly evaluates working memory, focal attention, executive function and brain processing speed through Event Related Potential (ERP) and quantitative EEG (qEEG) tests. A real-time, ready-to-read patient report is produced at the end of the testing session.

Helpful For

  • Differentiating dementia from depression
  • Detecting deficits in the brain early in the disease process
  • Tracking disease progression over time
  • Demonstrating medications are working
  • Facilitating better return to environment decisions post head injury
  • Predicting disease course and outcome after a concussion or TBI

Easy To Use

COGNISION® set up takes 10 minutes or less. Any technician can be trained in less than 3 hours and there are no upfront acquisition costs.

Convenient Features

  • Portable, wireless operation, and can be used in any clinical setting
  • Advanced active electrodes that produce high-quality data in any testing environment
  • Convenient HydroDot® biosensors designed for easy, rapid set-up with minimal clean-up
  • Subject-friendly headset fits a range of head sizes
  • No upfront acquisition costs

Proven Reimbursement

Clients from around the country have successfully received reimbursement from both Medicare and commercial payors. Clients are charged on a per-test basis.

During a COGNISION® concussion testing session, three separate procedures are performed:

Pure-tone Audiometry

There are two primary causes of post-concussive hearing loss: mechanical damage or neurological damage.

For example, if an injury affects the delicate hearing structures, the ear may not effectively transmit sound to the brain. This is the most common cause of hearing loss after head injury and can often be detected by performing a pure-tone audiometry test and reviewing the resultant audiogram.

Resting-state EEG

A brief resting-state EEG assessment can be an important tool to monitor and evaluate a wide range of brain networks and processes that may be impaired by concussion.

Among the most useful qEEG analytical approaches, spectral analysis, is of particular interest in the study of concussion and post-concussive symptoms. In this analysis, the raw EEG is transformed into frequency vs. power and plotted as a frequency spectrum.

Event-Related Potentials (ERP)

ERP testing involves recording EEG signals while the patient listens to a sequence of auditory stimuli through the same earphones used during the pure-tone audiometry test.

During the test, the patient is required to respond to certain auditory cues by pressing a button on the handset.

While the brain subconsciously analyzes the incoming stimuli, EEG signals time-locked to each stimulus are recorded.

Each of these tests targets synaptic networks in the brain that are often damaged from a concussion.

At the end of the testing session, the data is available for analysis and interpretation by a physician and can be transferred to a patient report, which will show the audiogram, EEG frequency spectrum, and ERP waveforms, each with a table of clinical biomarkers.

At this point, the physician can add specific biomarker and overall clinical findings that will automatically be included in the patient report.
