WAVi brain scan

What is a WAVi Brain Scan?

A WAVi brain scan is a non-invasive test that measures brain activity and health using electroencephalography (EEG):

HOW IT WORKS
The WAVi headset records brain waves while you perform tasks, and uses established benchmarks to provide information about brain activity, processing power, and more. The scan also analyzes the synchronicity between your heart and brain frequencies.

WHAT CAN IT DETECT

A WAVi scan can help detect early signs of neurological conditions, such as Alzheimer's disease, and is useful for people who play high-contact sports as it can detect concussion.

WHO IT'S FOR

A WAVi scan can be beneficial for anyone who wants to improve their brain health, including people with ADHD, chronic neurological conditions, depression, anxiety, concussion/brain injury or who are concerned about their memory.​​​​​​​

HOW IT'S USED
WAVi scans are quick and painless, and can be used by clinicians and researchers to measure brain state and track changes.

WHAT TO KNOW

The WAVi system is not intended to replace professional clinical evaluation.


What Do My WAVi Results Mean?


AUDIO P300

The P300 test is a subconscious measure of attention and memory where P300 Delay measures the brain's speed in recognizing the odd (high) tone and the P300 Voltage measures the quality of this recognition. We have found that a person's P300 response may be either fast or of high quality but it's less common to be both fast and high. These measures decline with age and are also affected by certain medications.

On a first time visit we measure P300 to get a baseline snapshot of where you naturally fall so that we can track your brain's performance. For example, we have found that improved cardio performance can increase your P300 speed and voltage. This measurement also allows us to track you over time. A P300 slowing and/or a reduction in voltage may signal reduced cognitive function and our goal is to keep you functioning on a high

PHYSICAL REACTION TIME
Physical reaction time measures the speed at which you click the mouse when you hear the odd tone. As with P300, this reaction time is known to slow with trauma, aging, and other conditions.
This measure relies on different pathways than the P300 and so your reaction time may be slower or faster than your brain. For this reason, physical reaction time compliments the P300. For example research shows in almost all cases, either a slowing in reaction time, a decrease in P300 voltage, or both are seen following a
concussive event.

TRAIL MAKING
The Trail Making Test is a standard measure of brain function and includes measures of psychomotor and visual scanning. The scores represent the amount of time required to complete the task.
As with reaction time and P300, research shows Trail Making performance declines with age, trauma, and other conditions.

THETA/BETA AT CZ
Just as sound waves vary in frequency, so do your brain waves. Brain wave bands are labeled from lowest to highest frequency as Delta, Theta, Alpha, Beta. Your administrator may have shown you Alpha and Beta waves during the test.

It has been found that the ratio of Theta/Beta power at the central electrode associates with cortical arousal. Research shows that individuals with high Theta/Beta ratios are more likely to have attention difficulties. This ratio gives us insight into how your brain functions, and provides a basis for measuring performance. While standard ADHD screenings are valuable diagnostic tools, the Theta/Beta ratio at CZ allows us to measure the effect of interventions on your brain.

F3/F4 ALPHA POWER
Differences in Alpha power between left and ride sides of the brain can provide information about emotional states. We measure the ratio of F3/F4 Alpha power where a number around 1.0 is the expected average. While standard depression and anxiety screenings are valuable diagnostic tools, the F3/F4 ratio allows us to measure the effect of interventions on your brain.

CONNECTIVITY
Coherence is a measure of the correlation between two EEG locations and may provide information about
functional connectivity between cortical regions. Numerous studies have linked coherence to various conditions associated with reduced cognitive function. For example, a lowering of front-back connectivity has been reported to correlate with the aging brain, where an increase in connectivity between more distant areas of the brain has been associated with injury.
