Neurodiagnostic Testing Overview

Home / Services / Neurodiagnostic Testing

EEG, Ambulatory Video EEG, EMG/NCV, Autonomic Testing, TM Flow, and Cognitive Testing

Neurodiagnostic testing can help clarify symptoms that are difficult to explain from history alone. Different tests evaluate different parts of the nervous system.

VerityMD Neurology offers a range of in-office and ambulatory neurodiagnostic services when clinically appropriate and ordered through the referral-based workflow.

Conditions We Help Evaluate or Manage

Services and How They Help

Routine EEG and Ambulatory Video EEG

EEG testing records brain electrical activity. Ambulatory video EEG records for a longer period at home when clinically appropriate.

How this helps:

  • Supports seizure and spell evaluation

  • Helps correlate events with brain wave activity

  • May help distinguish epileptic and nonepileptic events

EMG/NCV evaluates large nerve and muscle function.

How this helps:

  • Assesses neuropathy, radiculopathy, carpal tunnel, nerve injury, and weakness

  • Helps localize nerve or muscle problems

  • Guides treatment planning

Autonomic and Small Fiber Testing Using TM Flow

TM Flow testing evaluates selected autonomic, sudomotor, vascular, and cardiometabolic markers.

How this helps:

  • Supports evaluation of dizziness with standing, small fiber symptoms, diabetic neuropathy risk, and autonomic complaints

  • Complements EMG/NCV when both large and small nerve concerns are present

Cognitive Testing and Creyos

Cognitive testing helps measure memory, attention, language, executive function, and processing speed.

How this helps:

  • Provides baseline cognitive data

  • Tracks changes over time

  • Supports dementia, post-stroke, post-concussion, and medication-related evaluations

MS Diagnostic Evaluation

When multiple sclerosis is suspected or requires further evaluation, the neurologist may review neurological examination findings, MRI reports, laboratory results, and other relevant testing as part of the diagnostic process.

Patients with persistent symptoms after a head injury may require neurological evaluation after head injury, including review of previous imaging, testing, symptoms, and neurological examination findings.

Evaluating Movement Disorders

For suspected Parkinson’s disease or other movement disorders, neurological evaluation may include examination of movement patterns, review of prior testing and imaging, and assessment of other possible causes of symptoms.

When tremor is persistent, changing, or accompanied by other neurological symptoms, a tremor evaluation may help distinguish Parkinsonian tremor, essential tremor, medication effects, and other causes.

When Neurodiagnostic Testing May Be Helpful

For patients being evaluated for Alzheimer’s disease, neurological assessment may include review of cognitive testing, imaging, laboratory results, and other relevant diagnostic information before treatment decisions are made.

  • Referring provider needs EEG, EMG/NCV, autonomic testing, or cognitive testing

  • Symptoms remain unexplained after initial evaluation

  • Need to clarify seizure, neuropathy, autonomic, or cognitive concerns

What to Bring or Have the Referring Office Send

  • Referral from PCP, specialist, or referring provider

  • Medication list, including over-the-counter medications and supplements

  • Relevant office notes, hospital records, imaging reports, labs, and prior neurological testing if available

  • Test order or referral details

  • Prior testing reports

  • Relevant imaging and labs
