Some of the diseases being managed at Neurology Clinic
(Click on the small pictures to zoom)
  • Epilepsy and seizure disorders
  • Stroke
  • Encephaltis, Meningits and other Neurological infections
  • Polymyostis, Muscular dystrophies and other disorders of muscles
  • Myaesthenia gravis
  • Parkinson’d disease and other Movement disorders
  • Multiple sclerosis and other demyelinating disorders
  • Gulillain Barre Syndrome and other Neuropahies
  • Migraine and other headaches
  • Dementia
  • Paediatric Neurology cases

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.

Neurology Clinic has a 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.

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


  • Basic investigation for evaluation of seizure disorders
  • Pseudo seizure
  • Prognostication of seizure
  • Helpful in differentiating between seizure and syncope
  • Helps to find out the type of seizure which may guide the drug of choice
  • Non-convulsive status
  • Diagnostic for certain conditions like SSPE, CJD

Patient Preparation for EEG

  • Head should be shampooed; no hair-oil should be applied
  • No need to discontinue anti-epileptic drugs before EEG]
  • Normal meals are allowed before meal
  • Preferable to remove metallic ornaments like necklace, ear-rings etc

EMG & Nerve Conduction Studies
(Click on the small pictures to zoom)
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.

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

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

Patient Preparation for EMG & Nerve conduction studies
No restriction on meals
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

(Click on the small pictures to zoom)

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)

(Click on the small pictures to zoom)
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.

A digital ECG machine is also available in the clinic

Changing views about stroke Myth & Reality

Myth Reality
Stroke cannot be prevented Stroke can be prevented
Stroke is untreatable Stroke patients need urgent and energetic treatment
Stroke affects only old people Stroke can strike any age group
Stroke is a disease of heart Stroke is a "Brain Attack"
Stroke recovery only takes place for a few months after a stroke Stroke recovery continues for many years
