What You'll Learn
Brain electrical activity mapping is called BEAM
BEAM is a non-invasive and safe procedure that involves wearing a cap with sensors that record your brain's electrical activity. The process takes about 15-20 minutes and is painless. The data collected is then converted into a visual brain map report, which can be used to identify problem areas of the brain and suggest protocols for training the brain back into normal ranges.
EEG brain mapping can help identify if your brain function is being affected by nutritional deficiencies, environmental factors, genetic factors, sleep cycle dysfunction, or post-concussion activity. It provides an objective assessment of brain function, which can help direct the most effective brain health interventions.
The use of BEAM has seen rapid growth in the past decade, and it has been proposed as a potential diagnostic tool to identify underlying abnormalities in various neurological disorders such as Alzheimer's disease, epilepsy, and Parkinson's disease.

It is a method of extending the clinical utility of EEG data
Brain electrical activity mapping, also known as BEAM, is a method for extending the clinical utility of EEG data. BEAM is a topographic analysis of scalp-recorded EEG or evoked-potential (EP) data. It involves the use of computer-controlled topographic mapping to condense and summarise the spatiotemporal information contained in recordings from multiple scalp electrodes. This results in reduced data dimensionality and increased visibility, allowing for a more accurate and comprehensive understanding of brain activity.
BEAM has been applied in various clinical contexts, including the localisation of tumours in patients with normal or non-diagnostic EEGs, the differentiation of childhood absence epilepsy patients from controls by analysing their background brain electrical activity, and the study of childhood language disorders. It also aids in the identification of electrophysiological abnormalities in patients with functional lesions but normal CT scans.
The use of BEAM has enhanced the clinical utility of EEG data by providing a more detailed and nuanced understanding of brain electrical activity. This has led to improved diagnostic capabilities and informed treatment decisions. Furthermore, BEAM has helped overcome the limitations of traditional EEG analysis, which relies heavily on visual inspection of massive amounts of data, often resulting in reduced accuracy and limited utility.
In addition to its clinical applications, BEAM has also been used in research to study various mental disabilities, such as auditory processing disorder (APD), ADD, and ADHD. While EEG scans cannot be used reliably for diagnosing ADHD, they provide valuable insights into the neurophysiological changes that occur in the brain following a concussion.
Overall, BEAM is a powerful tool that extends the clinical utility of EEG data by facilitating more informed decision-making, improved diagnostic accuracy, and enhanced understanding of brain electrical activity, ultimately contributing to advancements in neurological research and patient care.

It helps to identify abnormal brain activity
Brain electrical activity mapping, also known as BEAM (Brain Electrical Activity Mapping), is a method for extending the clinical utility of EEG and evoked potential data. It is a powerful tool for understanding normal brain function and identifying abnormal brain activity. By mapping the range of healthy brain dynamics, it can help to identify subtle pathological events that may otherwise be concealed by healthy spatial variations.
The brain is a highly complex organ made up of billions of neurons that communicate via electrical impulses, creating brain waves. Brain mapping is an important tool for evaluating these brain waves and identifying areas of abnormal brain activity. This process involves placing a cap with sensors on the scalp to record electrical impulses, which is known as an electroencephalogram (EEG). The data is then converted into a visual brain map report, which can be used to identify problem areas within the brain.
The brain map report provides a clear and concise visual representation of the results, allowing for easy identification of abnormal brain activity. Each lobe of the brain is analysed for different types of brain waves, such as Delta, Theta, Alpha, and Beta, and colour-coded indicators show normal, lower, and very low levels. This helps to pinpoint areas of the brain that may be producing too much or too little electrical activity compared to a controlled, normative database.
Furthermore, EEG brain mapping can help identify if brain function is being affected by various factors such as nutritional deficiencies, environmental factors, genetic factors, sleep cycle dysfunction, or post-concussion activity. This information can then be used to recommend specific interventions such as nutritional changes, lifestyle modifications, or EEG biofeedback sessions to optimise brain electrical activity and return it to a normal resting state.
Overall, brain electrical activity mapping is a valuable technique for identifying abnormal brain activity and guiding effective brain health interventions.

It can be used to diagnose underlying abnormalities
Brain electrical activity mapping, also known as BEAM, is a method for extending the clinical utility of EEG and evoked potential data. It is a topographic analysis of scalp-recorded EEG or evoked potential data. BEAM can be used to diagnose underlying abnormalities in the brain by capturing and analyzing electrical impulses, which are then converted into a visual brain map report. This report displays the results for each lobe of the brain and each type of brain wave, with colours indicating normal and abnormal levels.
The brain map report can be used to identify any problem areas in the brain. It provides a visual representation of brain activity, allowing for the detection of abnormalities and the diagnosis of specific diseases. For example, the presence of theta and delta waves in a wakeful person can indicate brain dysfunction.
Quantitative EEG (qEEG) is a computer-assisted imaging and statistical analysis technique used to detect abnormalities and assist in diagnosis. It is relatively inexpensive and can non-invasively produce images of both excitatory and inhibitory cortical neuronal activity. qEEG can be used to assess neuropsychiatric disorders by examining the spectral composition of brain electrical activity and comparing it to healthy controls.
BEAM has been used to assess the levels of neurotransmitters such as acetylcholine, dopamine, GABA, and serotonin in adult patients. It has also been evaluated for its diagnostic accuracy in schizophrenia, bipolar disorders, and dementia.
Overall, brain electrical activity mapping is a valuable tool for diagnosing underlying abnormalities in the brain, providing a window into brain activity and facilitating the identification of problem areas.

It can be used to identify problem areas in the brain
Brain electrical activity mapping, also known as BEAM, qEEG, or simply brain mapping, is a powerful tool for understanding and treating neurological disorders. This non-invasive procedure involves placing a cap with sensors on the scalp to record electrical activity in the brain. The data is then used to create a detailed brain map, providing valuable insights into brain function and problem areas.
Brain mapping allows healthcare practitioners to identify abnormal brain activity and problem areas by comparing an individual's brain activity to that of healthy individuals of the same age. This process is known as normative brain mapping and helps determine which areas of the brain are affected, aiding in the development of targeted treatment plans.
The brain map report visually represents each lobe of the brain, including the frontal, parietal, central, temporal, and occipital lobes, and specific brain waves such as Delta, Theta, Alpha, and Beta waves. This comprehensive analysis helps identify areas of the brain that may require training or supplementation to return to normal ranges.
Additionally, brain mapping can be used to guide brain surgery, particularly in the treatment of epilepsy or tumors. This technique, known as intraoperative brain mapping, involves applying electrical stimulation to specific areas of the brain to understand their functions. By mapping language, motor, sensory, and vision areas, surgeons can identify and avoid regions that control important functions, ensuring safer and more precise surgeries.
Overall, brain electrical activity mapping is a valuable tool that provides a window into brain function, helping identify problem areas, develop targeted treatments, and guide surgical interventions for improved patient outcomes.
