What Happens After a qEEG Brain Map? 

At our clinic, qEEG is the foundation for a personalized neurotherapy plan. After the brain map is completed:

  • Dr. Chandra reviews the brain map results with each patient
  • Based on the patterns identified in each qEEG, she creates a neurotherapy treatment plan informed by the qEEG brain map, including ILF/Cygnet neurofeedback, Neurofield neuromodulation, or other supportive interventions as appropriate.
  • Treatment is tailored to symptoms, goals, and how patients respond over time. 

Why Work with Dr. Suruchi Chandra for qEEG Brain Mapping? 

qEEG quality varies widely, and one of the biggest differences is who interprets the data. Many clinics rely on automated, template-style reports. Dr. Suruchi Chandra uses a more careful, neuroscience-based approach in which every qEEG is personally reviewed by a Harvard- and Yale-trained psychiatrist with advanced training in neurotherapy and qEEG.

Dr. Chandra is Board-Certified in qEEG by the International QEEG Certification Board, one of the few clinicians in the DC region with this level of specialization. Each brain map is analyzed using research-grade tools such as ICA (Independent Component Analysis), ERP (Event-Related Potentials), HRV, and MATLAB-based processing to improve accuracy and reduce artifact. When helpful, she consults with leaders in the field to ensure each interpretation reflects the most current evidence.

Her Bethesda office is metro-accessible, walking distance, and approximately 3 miles from Washington, DC, making it convenient for individuals from Maryland and Northern Virginia (including McLean, Great Falls, and Arlington). 

What is the Legitimacy and Research Backing qEEGs? 

  • American Academy of Neurology (AAN) recognizes qEEG for clinical use in brain function assessment.
  • Peer-reviewed evidence supports its application in identifying neurophysiologic markers of mood and attention disorders (Arıkan & Ilhan, Clin EEG Neurosci., 2025).
  • Integration Evidence: Combining EEG-guided neurofeedback and TMS has shown additive benefits in rehabilitation and psychiatry (Romero et al., 2024). 

What are the limitations of a qEEG? 

qEEG provides valuable information but is only one piece of the larger clinical picture. Results are interpreted alongside history, symptoms, and other assessments.  

Can qEEG Diagnose Psychiatric Conditions? 

No. qEEG does not diagnose mental health or psychiatric disorders. Instead, it records and analyzes patterns of electrical activity that can correlate with and contribute to symptoms such as anxiety, inattention, or mood dysregulation. Diagnosis still depends on a full psychiatric assessment that includes history, symptoms, and clinical judgment.

qEEG can, however, support or clarify a clinical assessment by providing objective data about how different regions of the brain communicate. This can strengthen diagnostic accuracy and help tailor treatment plans. When interpreted alongside a full clinical evaluation, qEEG offers valuable insight into the functional brain patterns underlying emotional or cognitive symptoms, but it should never be used in isolation.

Those experiencing the following challenges may benefit from qEEG-guided neurofeedback:

  • Attention and focus challenges (ADHD)
  • Anxiety or mood regulation issues
  • Post-concussion symptoms
  • Depression or trauma-related dysregulation
  • Cognitive fog or fatigue
  • Sleep disturbances 

Who Might Benefit From qEEG-Guided Neurofeedback? 

  • Prevents guesswork: training is tailored to your specific patterns.
  • Tracks objective progress across sessions.
  • Ensures that changes seen in symptoms align with measurable brain changes. 

Why Does qEEG Matter Before Neurofeedback? 

What Is qEEG-Guided Neurofeedback?  

Neurofeedback is a form of brain training that teaches the brain to self-regulate. A qEEG provides the blueprint for this training. By identifying which regions are over- or under-active, the clinician can set individualized goals for feedback sessions.

During neurofeedback, sensors monitor your brainwaves in real time while you watch or listen to feedback (for example, a video that brightens when your brain moves toward the desired pattern). Over time, the brain learns healthier rhythms, much like physical therapy for the brain. 

Is qEEG Safe? 

  • Safe for all ages, including children and older adults.
  • Can be repeated to track progress. 

Are There Side Effects? 

Most people notice no side effects. A small number feel briefly tired or light-headed afterward, usually from concentrating or relaxing deeply during recording. These sensations fade quickly. 

Is qEEG Brain Mapping Painful? 

No. qEEG is completely painless and does not involve radiation or magnetic fields. The most you might feel is cool gel on the scalp or mild pressure from the cap. 
  1. Preparation: You sit comfortably in a chair while a clinician places a soft cap with embedded sensors on your scalp. The sensors pick up your brain’s natural electrical activity - they don’t send anything into your head.
  2. Recording: You relax with eyes closed and eyes open for several minutes. The computer records millions of microvolt signals.
  3. Artifact cleaning: Any muscle or movement noise is removed.
  4. Analysis: Specialized software compares your data to a large reference database and generates maps showing activity, coherence (communication), and symmetry.
  5. Review: Your clinician explains what the patterns mean in the context of your symptoms and goals. 

What Happens During a qEEG Brain Mapping Session? 

What Does a qEEG Show? 

A qEEG is a computerized analysis of the electrical signals produced by your brain. Every thought, mood, and movement reflects a pattern of rhythmic electrical activity. These rhythms are categorized as delta, theta, alpha, beta, and gamma waves.

While a standard EEG looks for more apparent abnormalities such as seizure activity, a qEEG analyzes the data mathematically, comparing your results to age- and sex-matched normative databases. The output is a color-coded brain map that highlights regions that may be under- or over-activated or not communicating efficiently.

A qEEG can teach you about:

  • How well your brain maintains focus or shifts between tasks (attention networks)
  • Emotional regulation and stress reactivity patterns
  • Sleep and relaxation rhythms
  • Post-concussion slowing or asymmetry
  • Cognitive speed and coordination between regions

This insight can explain why you may feel anxious, unfocused, fatigued, or foggy and helps target brain areas most likely to benefit from training. Your clinician may recommend qEEG when conventional tests like MRI or CT are normal, but symptoms persist. 

Key Points

  • What is a qEEG: qEEG is an advanced form of EEG that uses computer analysis to map brainwave patterns.
  • Who qEEG helps: People with ADHD, anxiety, depression, concussion, PTSD, sleep problems, or cognitive decline.
  • Why qEEG matters: It highlights how your brain functions in real time: information that structure-based scans (MRI, CT) can’t provide.
  • Safety of qEEG: Completely non-invasive; no electricity enters the body.
  • QEEG use in treatment: Creates a roadmap for qEEG-guided neurofeedback, neuromodulation, and other individualized interventions.  

Dr. Suruchi Chandra, a Harvard- and Yale-trained psychiatrist, brings together emerging neuroscience-based therapies, trauma-informed care, nutritional approaches, and systems-level biology to advance thinking in psychiatry and help more patients find clearer paths forward.

How qEEG Differs from a Standard EEG

What Is a qEEG Brain Map and How Is It Done? 

qEEG, or quantitative EEG, is a painless, non-invasive test that measures your brain’s electrical activity to create a visual “map” of how different regions communicate. It helps identify patterns related to focus, mood, anxiety, sleep, and concussion recovery. Unlike MRI or CT scans that show brain structure, qEEG reveals how the brain functions in real time. This insight guides personalized treatments such as neurofeedback and integrative approaches that promote balance and recovery.

  • qEEG (quantitative electroencephalography) measures your brain’s electrical activity and converts it into a detailed visual map.
  • It’s non-invasive, painless, and helps identify patterns linked to attention, mood, sleep, trauma, and concussion recovery.
  • The test guides personalized neurofeedback and treatment plans by showing how different regions communicate.
  • Results can reveal whether areas of the brain are overactive, underactive, or out of sync.
  • Safe for children and adults
  • May be reimbursable through out-of-network insurance benefits
