qEEG/ERP Analysis

A QEEG (Quantitative Electroencephalogram) is:

    • …also known as a “brain map”.
    • ..provides a baseline measurement of how the brain’s efficiency can be improved.  QEEG technology has been in use since the 1970’s and research shows it to be highly reliable. After the QEEG data is collected and processed, the results are compared to a database, chosen according to your individual needs.
    • …an evaluation for determining variations in brain function that are associated with different types of neurological disorders, including ADHD, Learning Disabilities, Depression, Dementia, Mild Head Injury, Anxiety Disorders, Migraine headaches, Sleep Disorders, Obsessive/Compulsive Disorder, and more. It also assures that the true underlying cause of the problem is addressed.
    • …able to provide a baseline measurement – the initial results are available for a later comparison should there be a desire to see if and how there have been changes in electrical activity of the brain.

The process of getting a QEEG done involves two steps:

Brainwave Recording

Be sure to follow the preparation instructions provided to you, including washing your hair thoroughly and not using any other hair products, including conditioner. Once you arrive at the office, expect that setting you up with the equipment will take approximately 1 hour.

Analysis of the Recorded Brainwave Data

After the EEG cap records data clearly on all 19 sensors for a total of 20 minutes, ½ with eyes open and ½ with eyes closed, the a client’s recorded brainwave performance can be statistically analyzed, and compared to that of a large population database. The psychologist doing the analysis is able to view and share the data in the form of colored brain maps, making it easy for clients to see the issues that are being explained, and improve the client’s (and family’s) understanding of his or her conditions.

SPS uses 4 different databases for data analysis. Depending on your concerns we will consult with international experts to analyze your data. Then, we use the analysis to develop a targeted therapeutic plan for you. SPS has been selected by HBImed, the developer of the most recent FDA approved brainwave database, to be the first office in the Northeast US to offer qEEGs with an ERP Analysis.

An ERP (event related potential) Analysis is:

An ERP (Event Related Potential) analysis involves analyzing the brain’s response response to a stimulus such as a sound or an image. This is done by analyzing the same kind of information that we collect for a qEEG analysis; the only difference is that this data is collected while you are involved in a task. That response is broken down into independent components, and then the characteristics of those components are compared with a normative database. The ERP analysis provides new insights into the different stages of information processing in patients.

In summary, the qEEG yields information about the resting state of the brain with eyes opened and eyes closed. The ERP analysis gives information about the information processing of the brain. Together, these two types of brain wave analysis yield valuable information about the effectiveness and efficiency of brain function.
