EEG & Ambulatory EEG Monitoring Services

---

What is an EEG?

     An Electroencephalogram (EEG) is a vital diagnostic test used to evaluate the electrical activity in the brain. It is an essential tool for diagnosing and managing a variety of neurological conditions, including:

• Epilepsy and psychogenic non-epileptic seizures (PNES).
• Traumatic brain injury (TBI) and concussions.
• Differentiation between fainting (syncope) and seizures. 
• Stroke  and assessment of coma depth.

Doctors utilize EEG data to not only diagnose these conditions but also to select and adjust medication for maximum treatment efficiency.

Ambulatory EEG: Advanced Monitoring at Home

Ambulatory EEG (AEEG).  While a standard EEG provides a snapshot of brain activity during a short doctor’s visit, an Ambulatory EEG is a more advanced, portable, wearable test that records activity for 24 hours or longer, offering a view into patient’s brain activity during waking hours, drowsiness and sleep. This extended monitoring offers a more comprehensive and accurate picture of your brain's electrical activity in your natural environment and leads to the most accurate diagnosis and treatment.

Why Choose Ambulatory Video-EEG-ECG?

At Synapse Neurodiagnostics, we offer routine "snapshot" EEGs, but we strive to go beyond standard monitoring. To provide the most accurate diagnosis, we integrate three powerful diagnostic tools:

1. Brain  Monitoring (EEG): continuous recording of brainwaves.
2. Video Monitoring: captures physical behavior to correlate with                                                brain activity.
3. Heart  Monitoring: records heart activity to rule out cardiac causes      for your symptoms such as Syncope.

    Previously, this level of sophisticated testing was confined to hospital Epilepsy Monitoring Units (EMU). Today, thanks to technological advancements, we bring this hospital-grade diagnostic capability to the comfort of your home.

Is a regular or ambulatory EEG painful?

No. EEG procedures are completely painless. The test does not involve any stimulation or electric shocks to the brain. The electrodes simply act as sensors to record the electrical waveforms that your brain is already roducing naturally.

Is at-home EEG monitoring as accurate as in-hospital monitoring?

Yes. Ambulatory (at-home) EEG monitoring has shown comparable accuracy to traditional in-hospital monitoring. In fact, monitoring in your home        environment can sometimes be superior. Being in a natural, stress-free setting allows us to capture your typical daily brain activity, which may better reveal the true nature of your condition compared to the artificial environment of hospital.

Is EEG testing available for children?

Yes. EEG procedures are safe and available for patients of all age groups, including infants and children. At-home testing is particularly beneficial for pediatric patients. Being in a familiar environment with family present reduces anxiety and keeps the child calm, which often results in higher-quality data and a more successful test.

When is hospital-based monitoring necessary?

Hospital-based monitoring (typically in an Epilepsy Monitoring Unit or EMU) is usually reserved for specific, high-risk cases. It is required for patients with confirmed epilepsy who need to undergo medication withdrawal (stopping anti-seizure drugs) safely under medical supervision. This is done to intentionally provoke seizures in order to quantify, characterize, and localize the seizure onset for surgical planning.

Are EEG services covered by insurance?

Yes. The majority of insurance providers, including Medicare, cover EEG services. Coverage requirements can vary; for example, plans like Medicare often do not require prior authorization, while private carriers might.

Clinical Conditions & Diagnostics

Is ambulatory EEG effective for diagnosing Epilepsy and seizures? 

Yes. Ambulatory EEG is a primary diagnostic tool for epilepsy, offering a significantly higher diagnostic yield than standard, short-term recordings. By monitoring brain activity continuously over 24 to 72 hours, it captures the patient's natural sleep-wake cycles and daily stressors, providing a more valid representation of their condition than a brief clinic visit. Why Ambulatory EEG is Valid for Epilepsy:

• Accurate Differentiation: It      allows neurologists to definitively distinguish between true epileptic      seizures and non-epileptic events (such as fainting, syncope, or      psychogenic attacks), ensuring patients are not medicated incorrectly.
• Increased Event Capture:      Standard EEGs only record for 20–30 minutes and often miss intermittent      abnormalities. Ambulatory testing dramatically increases the probability      of capturing a seizure or interictal discharge because it records for      days, not minutes.
• Video Correlation: When combined      with video, it provides the "gold standard" of diagnosis by      strictly correlating physical movements with electrical brain patterns,      validating whether a specific sensation or movement is truly neurological      in origin.

Is EEG helpful for Traumatic Brain Injury (TBI)?

     Yes. EEG is a powerful tool for diagnosing and managing TBI. It can detect abnormal brain activity even when physical clinical signs are subtle. It is particularly useful for differentiating TBI from conditions with similar symptoms, such as PTSD, and for identifying non-convulsive seizures.

How EEG Supports TBI Diagnosis:

• Early Detection: It can reveal functional changes in the brain shortly after an injury, often before structural damage appears on other tests.
• Severity Assessment: Specific brainwave patterns (such as slowing in the delta and theta bands) can indicate the severity of the injury and help predict recovery outcomes.
• The "Invisible" Injury: While CT scans show structural damage      (broken bones, bleeding), EEG reveals the functional impact. This      is crucial for mild TBIs (concussions) where a CT scan might appear      normal, yet the patient is suffering from cognitive issues.

Can EEG assist with accident-related medical claims?

Yes. EEG is frequently used to validate conditions resulting from accidents, such as car crashes or falls. It provides objective data on brain function that helps substantiate claims regarding Traumatic Brain Injuries (TBIs) or post-accident seizures.

What EEG Detects in Accident Victims:

• Brain Damage: It visualizes slowing or disruption in brain waves (such as  increased delta/theta activity) that indicates specific damaged areas.
• Seizure Activity: Head injuries significantly increase seizure risk. EEG can      identify these seizures, including "silent" (non-convulsive)      ones where the patient loses focus but does not convulse.
• Proof of Dysfunction: By showing how the brain is functioning in      real-time, EEG complements structural imaging like CT scans. A CT scan shows where the damage is; an EEG shows how the injury is      affecting the patient's daily life.

Does EEG help in stroke diagnosis?

 Key Benefits in Stroke Care:e MRI or CT) is the gold standard for locating a stroke, EEG plays a critical complementary role. It is valuable for early                                    detection, ruling out "stroke mimics" (like seizures), and assessing the severity of brain dysfunction caused by reduced blood flow.

Key Benefits in Stroke Care:

• Early Insight: EEG can detect ischemia (lack of blood flow) before visible changes appear on traditional imaging.
• Differentiation: It helps doctors determine if symptoms are caused by a stroke or a      seizure, ensuring the correct treatment is applied immediately.
• Outcome  Prediction: Abnormal patterns, such as focal slowing or asymmetry, can      help predict functional outcomes and the risk of post-stroke epilepsy.
