Electroencephalograms (EEGs) have been used for decades to help neurologists diagnose epilepsy, but by analyzing the electrical activity of the cerebral cortex via electrodes on the scalp and advanced algorithms, quantitative EEGs can provide even more information about brain wave patterns, the connectivity of the brain, and which brain regions may be "misfiring." This non-invasive form of neuroimaging guides patient-specific neurofeedback. It is also used to measure progress and is often done at the beginning and end of every treatment program.
Eye movements have been keenly reviewed by medical scientists to relate different brain networks to specific eye movements. Video oculography (VOG), also called video nystagmography (VNG) uses high tech goggles to record eye movements and analyze your pupils, even in the dark. These movements are translated into a graph that measures accuracy and speed of eye movements as well as the size and reactivity of your pupils.
Pupillometry stands as a validated clinical instrument, offering a swift and objective biomarker for autonomic responses. Its utility extends to serving as a clinical gauge for establishing optimal therapy dosages and acting as an indicator for neuro-integrity. Recent research has revealed the efficacy of examining variables within the pupillary light reflex (PLR) spectrum, encompassing factors like latency, maximum and minimum pupil diameter, maximum constriction velocity, and the 75% recovery time. These parameters prove instrumental in identifying whether an individual has undergone a concussion.
Our clinical team uses objective cognitive testing to determine which cognitive functions may be affected and to monitor improvements during and after treatment. By utilizing a 12-domain digital assessment, your cognitive strengths and weaknesses can be identified in the clinic as well as in the comfort of your own home. If further cognitive testing is required, our highly trained neuropsychologist can provide one-on-one cognitive testing via telehealth.
Balance is more than just standing upright. At GBI, we utilize computerized posturography with a modified clinical test of sensory integration and balance to help assess the different senses needed for balance including proprioception, vision, and vestibular function. These functions are associated with different regions of your nervous system including your cerebral cortex, cerebellum, brainstem, and spinal cord.
Magnetic resonance imaging is a medical imaging technique used to create pictures of the brain using strong magnetic fields, magnetic field gradients, and radio waves. Your doctor may request special types of MRIs such as DTI, SWI, NeuroQuant Sequencing, or fMRI which may be reviewed in office by our team of physicians. Not every patient requires an MRI and not all neurological conditions can be assessed with MRI. If you have a previous brain MRI, please bring the report and disc to your appointment.
