#Eeg brain free
In psychiatry, EEG brain mapping has been of value in identifying disorders of biological origin, such as schizophrenia, dementia, hyperactivity, depression, brain atrophy, and attention deficit disorders. This analysis can help identify problems that relate to cognitive and executive function, mood, anxiety, and attention. Statistical analysis of the EEG can compare your brain activity to a large sample of an age-specific normal population. New applications by psychiatrists and psychologists use a digital analysis of the EEG for different purposes. The picture on the right displays a relatively normal brain, without depression.ĮEG’s are commonly used by neurologists to determine the presence of seizures, arteriovenous malformations, and stroke. This pattern is often associated with depression. It represents an excess amount of slow brainwave activity.
On the left, there is an orange and yellow area. The map on the left is from a person with a long history of depression. The two brain map images below are from different people. Many researchers feel that the qEEG represents evidence-based medicine and is on the cutting edge in neurofeedback. They use other models for training the brain. There are also many clinicians who find the qEEG very technical with a steep learning curve. Some individuals teaching neurofeedback have said that qEEG mapping isn’t necessary, and that there are other ways to get good results. While there are a growing number of clinicians using qEEG brain mapping, there is disagreement in the field about qEEGs. More research and a growing body of clinician experience suggests training coherence with neurofeedback may be an important component to an efficient brain. A qEEG brain map is one of the few tools that helps assess coherence. If two areas are communicating too little or too much, it can interfere with the efficiency of the brain. There is constant communication between different areas of the brain. In very simple terms, coherence measures how well-coordinated the communication is between one area of the brain and another. If one or more areas of the brain is running too slowly or too fast, it causes problems such as attention, emotional control, mood, or behavior.Īnother measure is called “coherence”. Each area of the brain plays an important role. For neurofeedback, it provides a guide to where to train. This information is sometimes used to help suggest appropriate medications. An EEG brain map helps identify where the brain has specific problems – and helps target the kind of interventions.

Much like a blood test, the clinician must know how to interpret the test results, including which are significant and relate to the client’s problems. There are hundreds, even thousands, of measurements. The qEEG report helps identify where significant differences exist between the person being tested and the normative group. These databases compare the individual’s EEG pattern with a group of carefully-selected, normal, healthy people in a similar age group. The EEG patterns from an individual’s brain are compared with a “normative database” of other individual EEGs. It shows brain timing issues which impact mood, behavior, and attention, and it measures cortical timing. But the EEG map provides the best information for neurofeedback training. There are many types of brain maps – including MRIs, PET scans, and SPECT scans. It gives a snapshot picture of what’s going on in the brain. An important assessment tool is an EEG brain map.
