**Brain mapping (QEEG)** is one of the accurate and diagnostic tests for brain, neurological and mental disorders, one of its advantages is that it is non-invasive, for this reason this test has no age limit and can be performed from a 9-month-old child to a 105-year-old patient. Colloquially sometimes referred to as "brain map".. QEEG is an extension of EEG visual interpretation analysis that may help and even enhance our understanding of EEG and the brain.. Multi-electrode recording using a computer... Processed EEG is usually converted into color maps of brain function called "brain maps".. EEG and derived QEEG information can be used by professionals as a clinical tool to assess brain function and track changes in brain function due to various interventions such as rTMS, neurofeedback or drugs can be interpreted and used... EEG/QEEG processing software gives us the ability to observe the dynamic changes that occur throughout the brain during cognitive processing tasks, and this new approach can help us determine the brain regions involved and efficient processing... Algorithms... QEEG brings new techniques to extract features of EEG signals, from Sentence: - Analysis of specific frequency bands and signal complexity - Connection analysis - Network analysis The clinical application of QEEG is extensive, including: - Nervous and mental disorders - epilepsy - stroke - Dementia - Traumatic brain injury - Mental health disorders It can be concluded that to date, the role of QEEG is not necessarily to accurately determine an immediate diagnosis, but to provide additional insight in conjunction with other diagnostic evaluations in order to obtain the objective information necessary to achieve an accurate diagnosis, correct assessment of disease severity, and specific therapeutic response.. EEGs can reveal important information about your overall brain function, including stress levels, thought patterns, and emotions.. QEEG can show brain wave patterns that are associated with impulsivity, cognitive inflexibility, QEEG anxiety, and other symptoms... The American Academy of Neurology (AAN) and the American Clinical Neurophysiology Society (ACNS) state that QEEG can be used in the following conditions: - Screening for possible epileptic seizures - Screening for epileptic seizures in patients at risk - In the intensive care unit (ICU), preoperative evaluation in drug-resistant epilepsy - Diagnosis of acute intracranial complications during surgery - Evaluation of patients with symptoms of cerebrovascular disease - Assessing the severity of dementia and encephalopathies On the other hand, experimental studies have shown that QEEG can be used for the following conditions: - Post concussion syndrome - Mild or moderate brain damage - stroke - Dementia - Attention deficit disorder Hyperactivity disorder - Psychosis - Depression - Anxiety - bipolar - obsession - Practical obsession - Sleep disorder - Learning disorder - Weakness of memory - Alzheimer's - Parkinson's - Hand tremors - Alcohol addiction - buzzing Areas that can be investigated by QEEG Using QEEG, the following areas can be checked: - Drugs, alcohol and recreational drugs - Mood problems, learning problems, sensory sensitivities, attention problems, autism spectrum problems, psychological injuries - Immunity problems, post-concussion syndrome, cardiovascular problems, metabolic problems - Nervous modulation ### Drugs, alcohol and recreational drugs QEEG can show the effects of substances that have been used before... It can also provide valuable information about drugs that are appropriate for brain and psychiatric problems, such as stimulants (Ritalin, etc.), antidepressants (Citalopram, Sertraline, etc.), anticonvulsants (Epilim, lamotrigine, etc.)... QEEG can show markers of vulnerability in other aspects of body function that may require further investigation. Many symptoms can be common to several diagnostic categories.. An example might be that difficulty concentrating can be the result of any of the following or a combination of fatigue, pain, attention deficit disorder, brain injury, family stress, work stress, depression, and anxiety. rTMS, neurofeedback, biofeedback, audio-visual bubble, direct or alternating current stimulation, stress management techniques, educational interventions, and referrals to other health professionals... In recent years, at the Neural Neurology Center, we have performed more than 2,000 quantitative electroencephalograms (QEEGs), which measure electrical activity. Information obtained from QEEG.. We are waiting for you dear ones...
