Diagnosing MS

Detecting Multiple Sclerosis can be difficult. It is often
several years from first symptoms to certain diagnosis,
because:

- early symptoms are often so
slight that the person doesn't
go to a doctor

- other diseases of the central
nervous system have some of
the same warning signs as MS

MRI (magnetic resonance imaging) is currently the preferred method of imaging the brain to detect the presence of plaques or scarring caused by MS. It is better at detecting plaques than CT scanning. Often brains that appear to be normal on CT scans will be shown to have plaques on MRI.

Imaging scans of the brain and spinal cord usually
show characteristic changes, and electrical tests and
spinal fluid examination may give helpful information

Doctors look for two things
before confirming MS

1. Signs of Nervous System Damage

Numbness or tingling of hands and feet, unexplained
weakness or paralysis, etc., may occur. Two or more
parts of the central nervous system must be involved.

2. Come-and-Go Pattern (relapses and
remissions)

Symptoms of MS usually appear and disappear
unpredictably.
