Neurologists treat disorders of
the brain, spinal cord, nerves and muscles. Some common symptoms of
neurologic disorders are:
Head ache
Speech & swallowing disorders
Fits
walking or balancing difficulty
Dizziness
Visual disturbances
Loss of conciousness
Tingling or numbness
Weekness & paralusis
Bladder control
Sleep disturbances
The department of Neurology at Mann Mediciti is one of the finest in
the country. Manned by highly qualified full-time senior
consultants, and backed by a state of the art clinical
neurophysiology lab (EMG, NCV, EEG, Evoked Potentials),
neuroradiology including computed tomography (CT), magnetic
resonance imaging (MRI), digital subtraction angiography (DSA),
extracranial and intracranial vascular Doppler, single photon
emmission computed tomography (SPECT) and interventional
neuroradiology and excellent neuropathological backup, the
department is equipped to manage any neurological disorder. World
class critical care units (CCU) are geared to deal rapidly with
'brain attack' and other neurological emergencies round the clock. A
physiotherapy and rehabilitation department offers exceptional
neurorehabilitation to help stricken patients overcome their
disabilities.

EMG
During an EMG, the neurologist analyses the electric activity in
muscles by inserting a fine needle electrode into selected muscles.
Needle insertion may cause mild temporary discomfort. The needle is
not used for injection and no shocks are given. The physician can
determine whether the muscle is working normally by seeing the
electric activity on a screen and listening over a loudspeaker. The
needles are discarded after use or sterilised to prevent the
transmission of AIDS, hepatitis and other infections.
NCV
To perform nerve conduction studies, the physician tapes small metal
electrodes on the skin and applies a brief electric stimulus to one
portion of a nerve. Nerve stimulation will cause a tingling
sensation. The physician can then evaluate the electric response of
the nerve or muscle to which the nerve is attached and determine if
the nerve impulse is a) conducted normally, b) at a slow speed or c)
not transmitted at all, suggesting damage to the nerve.
Evoked Potentials
Electrodiagnosis may also include a number of other tests, such as
evoked potentials. These studies use different stimuli, such as
auditory clicks, a changing visual pattern such as a checkerboard,
or small electric stimuli applied to specific nerves. The recordings
are made over the surface of the head and the spine to evaluate
whether the sensory impulses are conducting normally through the
nerves, spinal cord or brain.
Special Precautions
The patient does not need to do anything special to prepare for this
test, except to keep the skin free of any lotions or emollients on
the day of the examination. Be sure to inform the physician,
however, if you are taking blood-thinning medication such as
Coumadin, have hemophilia or a cardiac pacemaker. Patients with
myasthenia gravis should ask their physician whether or not to take
anticholinesterase medications on the day of the test.
