EEG
Electroencephalography is a simple, non-invasive and essential investigation for the evaluation of seizure disorders. It picks up the electrical activity of brain from different
regions as recorded from electrodes placed on scalp
Equipment
Neurology Clinic has the latest and most modern 32 Channel Digital EEG machine which does simultaneous video recording of all the activities of the patient during the procedure.
Hard copy of representative pages of EEG recording are given along with the report to patients.
EEG recording on CD
EEG recording of patients can be given on a CD and it can be reviewed by other neurophysicians on any computer and is also useful for future reference. Photo
Recording Time
Approximately 30 minutes
EMG & Nerve Conduction Studies
Motor and sensory nerve conduction study (MNCV and SNAP ) -test the electrical conduction of motor / sensory impulse by that nerve.
EMG (electromyography) tests the electrical contractile properties of a muscle.
Equipment
EMG, MNCV and SNAP are recorded on the same machine which is computer based. The data of patients are stored on hard disk of computer for analysis and future reference Photo.
Indications
All types of neuropathies (diseases of nerves) -
Myopathies ( diseases of muscles)
-
Myaesthenia gravis and other myo-neural junction disorders
-
Systemic disorders like diabetes mellitus affecting the nerves
-
Myopathies ( diseases of muscles)
Patient Preparation for EMG & Nerve conduction studies
All types of neuropathies (diseases of nerves) -
-
Limbs should be cleaned thoroughly with soap and water
-
Rings and bangles should be removed if possible
-
Recording time : 60 minutes (approx..)
Evoked potential Studies
Visual Evoked Potential Study (VEP)
VEP are electrical potential differences recorded from scalp produced in response to visual stimuli. For normal responses the entire visual system should be intact and disturbances anywhere can produce abnormal VEP's.
Brainstem Auditory Evoked Potential Study (BAER)
BAER are the potentials recorded from ear and vertex produced in response to a brief auditory stimulation to assess the conduction through the auditory pathway upto mid-brain
For normal responses the entire auditory pathway should be intact and disturbances anywhere can produce abnormal BAER.
Somatosensory Evoked Potential Study (SSEP)
SSEP are the electrical potentials produced by the large diameter sensory fibres in the peripheral and central portion of the nervous system produced in response to a sensory stimulus.
ECG
A digital ECG machine is also available in the clinic
