How one physician incorporates Geodesic EEG into his practice

At The Center for Neurological and Neurodevelopmental Health (CNNH) in Gibbsboro, New Jersey, Dr. Mark Mintz and his associates have implemented dense array EEG (dEEG) assessment, using the Geodesic EEG System 300, in their routine EEG evaluation of children, including those who have developmental, behavioral, or pervasive personality disorders, are developmentally delayed, or who have had traumatic experiences with conventional EEG previously, without the need for sedation or restraint.

Dr. Mintz describes the goals of his practice: "There are many children and adults with special needs who would diagnostically benefit from the information provided by an EEG, but cannot obtain one because of severe behavioral reactions and non-compliance. However, with the use of dEEG and the patient-friendly sensor net, we have been able to obtain high-quality EEG data from this "underserved" special needs population. In many cases, previous neurologists unsuccessfully tried to obtain conventional EEG studies, or used restraint or sedation, rendering the studies unreliable. Dense array EEG overcomes the obstacles of conventional EEG, providing access to advanced technologies for diagnostically "underserved" populations".

The CNNH provides advanced care for patients

Serving an ever-growing outpatient community, The Center for Neurological and Neurodevelopmental Health (CNNH), located in Gibbsboro, New Jersey, provides neurological and neurodevelopmental diagnostic and treatment services for children, adolescents, and adults. Patients at CNNH include children and adults with neurodevelopmental disabilities, neurobehavioral and neuropsychiatric disorders, brain injury, and other neurological problems. Led by Mark Mintz, MD, the CNNH provides advanced noninvasive techniques for assessing brain function in an outpatient setting.

Dense array EEG used for diagnosis and monitoring

Key to the center’s services is dense array electroencephalography (dEEG), “Dense Array EEG is a useful clinical tool in our office for the detection of electrical abnormalities associated with seizure activity (i.e., epilepsy), but also for subclinical electrical activity that might be interfering with attention or learning,” says Dr. Mintz. 

EGI’s 128-channel Geodesic EEG System 300 provides the center with much higher resolution EEG data compared with the older, low-channel technology typically used, a significant improvement over standard approaches to outpatient EEG. EGI’s integrated GeoSource source estimation software also adds a powerful tool for the localization of the source of any abnormal electrical activity.

EGI’s electrode placement technology improves patient experience


In addition to higher resolution data, Dr. Mintz says that EGI’s HydroCel Geodesic Sensor Net provides “an ingenious way to apply the large number of electrodes…in minutes. The application is painless, reduces patient anxiety about the test, and thereby increases compliance.” Further, there is a reduced risk of infection as “there is no abrasion of the scalp, as is used with standard EEG.” Perhaps more importantly, the Net technique requires no patient sedation or restraint, providing a better patient experience, higher quality of data, and better diagnostic capabilities.
