THE TECHNOLOGY

EEG: A Window into Mental Health

Electroencephalography (EEG) measures electrical activity in the brain, offering valuable insights into mental states such as stress, anxiety, and depression.

How EEG Works in MindChat

MindChat integrates with compatible EEG headsets like Muse 2 for non-invasive brainwave monitoring. While not a diagnostic tool, EEG signals offer objective physiological data points. These can correlate with changes in mental state (like stress or mood shifts), acting as potential indicators alongside self-reports.

Alpha Asymmetry Detection

Variations in alpha wave activity between the brain's hemispheres are associated with mood states like anxiety and depression. MindChat algorithms detect these patterns to provide valuable insights.

Beta Activity Monitoring

Elevated beta waves (13–30 Hz) reliably track acute stress and hyper-arousal, so MindChat relies on beta metrics for real-time stress or anxiety alerts. Gamma (>30 Hz) is displayed only when high-quality data are available and should be considered exploratory due to hardware noise constraints.

Important Considerations:

Consumer EEG devices like Muse are sensitive to artifacts (muscle tension, eye blinks). MindChat employs signal processing techniques, but results are most reliable under calm conditions. EEG patterns show correlations, not causation, and interpretation requires context. Gamma band data (>30Hz) is highly susceptible to noise on consumer hardware and should be viewed as exploratory.

Why MUSE?

We selected the Muse 2 based on independent studies indicating its capability to capture key metrics like frontal alpha asymmetry and basic spectral power (alpha, beta, theta) comparable to some research systems under specific conditions1. This allows MindChat to analyze relevant correlates of mood and stress, while our algorithms work to mitigate potential noise.

POST-IMPACT EEG MONITORING

Supporting Concussion Awareness with EEG Data*

*Disclaimer: MindChat provides EEG data to support awareness after a suspected impact. It is NOT a diagnostic tool for concussion and cannot replace evaluation by a qualified healthcare professional. Always follow established concussion protocols.

Following a suspected impact, MindChat allows for immediate EEG data capture. Our analysis identifies potential changes in EEG biomarkers associated with neurological disruption, providing objective data points within minutes to supplement observational checks. This information can assist personnel in following appropriate concussion protocols and facilitate informed communication with medical providers.

Concussion Detection Technology

EEG Biomarkers Associated with Concussion

Following head impacts, concussions can cause measurable changes in the brain's electrical activity. MindChat analyzes EEG data for patterns that have been associated with such neurological disruptions in research literature:

Power Spectrum Analysis

Concussion research often associates impacts with changes in EEG power, such as potential increases in slow-wave activity (delta/theta) and decreases in faster waves (alpha/beta). MindChat analyzes the power spectrum for patterns that may correlate with these reported post-impact changes, offering data points for consideration alongside clinical signs.

Functional Connectivity Patterns

Research suggests concussions can alter typical communication patterns (functional connectivity) between brain regions. MindChat evaluates connectivity metrics, looking for deviations from baseline or expected patterns that have been associated with post-concussion states in scientific literature.

Task-Related Activity Analysis

MindChat analyzes brain responses during specific cognitive tasks (when available). Changes in these response patterns can sometimes indicate altered cognitive processing speed or attention, which are known potential correlates following concussion.

Why Objective Data Matters

Because concussion symptoms are not always immediately apparent, objective EEG data captured soon after a potential impact can provide valuable supplementary information to aid awareness and support timely implementation of appropriate management protocols.

BRAIN ACTIVITY

Understanding Brainwaves

Explore the different brainwave types and their associated mental states that MindChat monitors to provide insights into your mental well-being.

Delta

0.5–4 Hz

Associated with deep sleep and restorative processes. These slow waves are essential for physical healing and recovery.

Theta

4–8 Hz

Present during meditation, creativity, and daydreaming. Theta waves facilitate memory formation and emotional processing.

Alpha

8–12 Hz

Dominant during relaxation and calmness. Alpha waves are indicators of mental relaxation and reduced anxiety states.

Beta

12–30 Hz

Prevalent during active thinking, focus, and stress. Elevated beta activity often correlates with mental strain and anxiety.

Gamma

30–100 Hz

Linked to high-level information processing. Because Muse sensors are noisy above 30 Hz, MindChat reports gamma only as an exploratory trend.

HOW WE READ YOUR BRAIN

The Science Behind Our Metrics

Every MindChat alert is anchored in peer-reviewed EEG literature curated by our Chief Neuroscientist. Here are the key biomarkers we track (see full reference list).

Alpha (8-12 Hz)

Typically higher during relaxation and lower during anxiety.
MindChat watch-point → Sustained alpha drop may correlate with rising stress4.

Beta (13-30 Hz)

Increases with focused thinking, workload or acute stress.
MindChat watch-point → beta spikes trigger a Stress / Anxiety alert5.

Frontal Alpha Asymmetry

Imbalance between left & right frontal alpha is linked to mood regulation and depression-risk6.
MindChat watch-point → persistent asymmetry raises a Depression Risk alert.

Example AI Coach Reply – Mood Concern

John Doe: “MindChat says my depression risk is high—what can I do?”

MindChat AI Coach voice: Your result show a potential persistent left-frontal alpha asymmetry pattern, a biomarker linked to low mood7. This is a risk indicator, not a diagnosis. Research-backed steps that often help include:

  • 30 min of moderate exercise most days. A meta-analysis reported a 26 % mean reduction in depressive symptoms (Schuch et al., 2016)8.
  • Daily “pleasant-event scheduling” (behavioural activation)9.
  • Two sessions of slow diaphragmatic breathing; an 8-week trial lowered depression scores significantly (Zaccaro et al., 2018)10.

If low mood persists or worsens, please consider consulting a mental-health professional. Let me know if you need more examples or recommendations.
