The Electroencephalogram (EEG) test necessary for the diagnosis of many neurological disorders like epilepsy, meningitis, brain swelling, brains stroke, sleep disorders has been started at Bhopal Memorial Hospital and Research Center (BMHRC).
Dr. Manisha Srivastava, Director-in-charge of BMHRC on Saturday dedicated the new state of the art EEG machine to the patients. A video camera is installed in this machine, which will record every activity of the patient during the examination.
It will help the doctor to analyze the exact status of the disease and condition of the patient.Dr. Manisha Shrivastava said that with the help of EEG test, normal and abnormal condition of the brain is revealed. EEG test is used to detect many types of brain disorders like brain stroke, meningitis, brain swelling etc. This machine also has an important contribution in the diagnosis of many mental diseases like psychogenic non-epileptic seizures, Neurodevelopment disorder narcolepsy etc.
This will benefit many patients coming to the hospital. How EEG works : Dr Chandrashekhar Rawat, Assistant Professor, Department of Neurology, BMHRC said,”An EEG machine records the electrical activity of the brain. It contains electrodes that can detect brain activity when placed on a subject’s scalp. The electrodes record the brain wave patterns and the EEG machine sends the data to a computer or cloud server.
The electrical impulses in an EEG recording look like wavy lines with peaks and valleys. These lines allow doctors to quickly assess whether there are abnormal patterns. Irregularities may be a sign of seizures or other brain disorders. For example, when an epileptic attack occurs, the EEG lines start fluctuating rapidly during its testing. In patients who have a tumour in the brain or are suffering from brain stroke, the frequency of their EEG waves decreases.
Through these signs the doctor identifies the patient's disease.” Important for examining children suffering from Neurodevelopment Disorder: Dr. Jyotsna Jain, Assistant Professor, Department of Psychiatry, BMHRC, said that sometimes symptoms of epilepsy are seen in patients who are under extreme stress or depression, but in reality they do not have epilepsy. This is called psychogenic non-epileptic seizure. The EEG machine itself confirms that the patient does not have epilepsy. Apart from this, symptoms of epilepsy are also seen in children suffering from Neurodevelopment disorder (children whose brain is not developed). EEG test is also necessary for its diagnosis.
