What are the Benefits of an Electroencephalogram

An electroencephalogram or EEG is a non-invasive technique that measures the electrical activity of the brain. This method is widely used in various fields such as clinical neurology, neurofeedback and communication, cognitive neuroscience research and even marketing and consumer research to analyse and monitor brain activity. Along with its usage in various fields, EEG also has multifaceted benefits. Let us delve into them one by one in the following article.

Why is an EEG Performed?

EEG has been used since 1929 as a technique to measure brain activities. However, with the advancement in technology, the tools and software used for EEG have also evolved, ensuring more accurate results. For instance, many organisations trust BrainAccess EEG solutions for accurate results, ease of use, and high-tech features.

An EEG is generally performed to analyse neurological problems such as seizure disorders, injuries, encephalitis, brain tumours, sleep disorders and dementia. However, currently, it is widely used in sports to assess brain functions and abnormalities in athletes who suffer concussions as well. It is also used in consumer behavioural science to understand consumer preference and engagement with a product. EEG has numerous benefits, making it a popular method among researchers and clinicians. Some of them are mentioned below:

Benefits of EEG

  1. Diagnoses Neurological Disorders:

Clinicians widely use EEG to diagnose and treat neurological disorders such as epilepsy, dementia, brain tumours, head injury and concussion, encephalitis and sleep disorders. However, you will need software to collect data from EGG. Many software have comfortable EEG caps to ensure accurate data collection and analysis. For instance, an EEG cap from BrainAccess offers ease of use and comfort.

  1. Helps in Cognitive Research:

EEG works like a window into the brain of the individual and records brain activities associated with various cognitive processes. EEG is used to study memory, attention, language processing and other aspects of human cognition, which can be a great tool in neuroscience research to investigate brain functions.

  1. Assists in Neurofeedback Therapy:

EEG is the cornerstone of neurofeedback therapy. It uses real-time monitoring of brain activity to regulate an individual’s brain function. It has proven to be an effective tool in curing mental health issues such as ADHD, anxiety and certain other mood disorders.

  1. Development of Brain-Computer Interfaces:

EEG plays a pivotal role in the development of brain-computer interfaces. These interfaces enable direct communication between the brain and external devices, offering new possibilities for individuals with motor impairments.


The adaptability of EEG makes it a valuable tool in diverse fields ranging from clinical research and cognitive therapy to understanding consumer behaviour and marketing. However, you must avail yourself of good software services for accurate data measurement and ease of use.
