EEG and VNG testing provide objective neurological data that standard imaging cannot — crucial for evaluating TBI, seizures, dizziness, and chronic pain with a neurological component. Both are available in-house at Mind and Body Pain Clinic in San Jose.
The Role of Diagnostic Neurology in Pain and TBI Care
Effective treatment of neurological conditions depends on accurate diagnosis — and accurate diagnosis often requires objective testing beyond a clinical examination alone. Two of the most informative diagnostic tools available at Mind and Body Pain Clinic in San Jose are EEG (Electroencephalography) and VNG (Videonystagmography), both of which provide real-time data about how specific parts of the nervous system are functioning.
For patients with traumatic brain injury, chronic headaches, dizziness, balance disorders, or neurological conditions affecting cognition or movement, EEG and VNG can reveal abnormalities that are invisible on standard MRI or CT imaging — and that directly guide treatment decisions.
EEG — Measuring Brain Electrical Activity
An EEG records the electrical activity of the brain using electrodes placed on the scalp. It is the primary diagnostic tool for seizure disorders and epilepsy, TBI-related brain dysfunction, sleep-related neurological conditions, and altered states of consciousness. Post-traumatic EEG abnormalities can persist long after the injury and help explain cognitive, behavioral, or pain-related symptoms that standard imaging misses.
In the context of TBI evaluation, EEG is particularly important because MRI and CT scans often appear normal even when significant neurophysiological dysfunction is present. Quantitative EEG can document objective functional changes that support diagnosis, guide treatment, and provide medico-legal documentation for workers' compensation or personal injury claims. At Mind and Body Pain Clinic, EEG is performed and interpreted in-house by Dr. Singh — not outsourced to a reading service.
VNG — Evaluating the Vestibular System
Videonystagmography (VNG) is a battery of tests that assess the vestibular (inner ear and balance) system by measuring eye movements under controlled conditions. It is the gold-standard diagnostic test for dizziness and vertigo of vestibular origin, balance disorders following TBI or concussion, benign paroxysmal positional vertigo (BPPV), and distinguishing central from peripheral vestibular pathology.
Many patients with TBI experience persistent dizziness, imbalance, and visual disturbance that are incorrectly attributed to anxiety or post-concussion syndrome without a formal vestibular evaluation. VNG testing identifies specific vestibular deficits that respond to targeted vestibular rehabilitation or medical management — reducing unnecessary medication trials and accelerating recovery.
Getting Diagnostic Testing in San Jose
EEG and VNG testing are available at Mind and Body Pain Clinic's San Jose office (6010 Hellyer Avenue, Suite 150, 95138). Tests are ordered as part of a comprehensive evaluation and interpreted by Dr. Harpreet Singh directly, allowing immediate integration of findings into your treatment plan — not a days-long wait for a remote reading.
