Can a EEG biofeedback system be used at home for cognitive training?

Can a EEG biofeedback system be used at home for cognitive training?

Home use of EEG : Is not recommended because proper use of an eeg system requires extensive training & sophisticated & carefully calibrated equipment. It would be much preferable to find a certified professional through www.Bcia.Org or www.Aapb.Org. ...Read more

Eeg (Definition)

An electroencephaolgram (eeg) is a test that uses wires on the scalp to measure electrical activity produced by the brain. It is used to assess cerebral activity, and can be very helpful in the diagnosis and treatment of seizures as well ...Read more

What is an EEG for?

What is an EEG for?

Brain activity: Eeg is a test of physiological function, and records brain electical activity (like electrocardiogram for heart). It is used to check for seizure activity, to evaluate various headache issues, to check patients with memory loss, evaluated folks with brain infections, and also confirm brain death. ...Read more

How does an EEG work?

How does an EEG work?

Captures brain waves: Scalp electrodes are placed on designated brain areas. They are connected to amplifiers and to computers, which records brain electrical activity, for a minimum of 20 minutes. Information is filtered and displayed on a computer screen. It is interpreted by a neurologist. Different brain waves may be abnormal or normal. Eeg may be used to detect seizures, or other non-seizure abnormalities. ...Read more

How reliable is an eeg?

VAGUELY ACCURATE: An EEG is a recording of brain electrical activity taken over the scalp, over about 45 minutes. This brief period may completely miss many paroxysmal events and provide a false negative/normal result. Work with direct electrodes implanted into brain have convincingly demonstrated far more pathology than external recordings. So, basically "hit or miss" issues, and better to clinically assess. ...Read more

How does the EEG test work?

Records brain: Electrical activity occurs thruout the body, and like an electrocardiogram recording heart activity, small discs are taped to specific areas of the scalp, and pickup underlying electrical impulses from brain activity. The rhythms vary during sleep and waking, and are compared to normal expectations. Diffuse slowing may correlate with diffuse problems, and paroxysmal activity may indicate seizure. ...Read more

What is the point of an eeg?

Uses of an EEG: An EEG is normally used to help determine the cause and likelihood of a person to have a seizure. In the hospital, the EEG is sometimes used to help determine the cause of altered consciousness. ...Read more

Will it show up if I smoke on eeg?

EEG: Measures the electrical activity of the brain. Various drugs when taken in larger does can cause changes in a patient's eeg. Usual doses of nicotine will likely not cause eeg changes. ...Read more

How much time does an EEG test take?

About an hour : A routine eeg takes half an hour, but there is additional time needed to put on and take down the electrodes. That being said, sometimes we will run studies for longer time periods (days at a time) in hopes of capturing a rare event. ...Read more
