Clinical Pearls:Diagnosis of MS
Diagnosing Multiple Sclerosis
[Clinician Reviews 9(7):72, 1999. © 1999 Clinicians Publishing Group and Williams & Wilkins]

Early diagnosis of multiple sclerosis rests solely on a high index of suspicion based on reported signs and symptoms whose course is marked by remissions and exacerbation. A mnemonic for the clinical features of multiple sclerosis is VISUAL:
V: Visual disturbances (blurring, fogginess, haziness, temporary blindness, double vision, eyeball pain).
I: Internuclear ophthalmoplegia (ie, of the brain stem pathway that coordinates eye movement), which causes paresis of the medial rectus muscle on lateral conjugate gaze, but not on convergence; nystagmus is seen in the abducting eye.
S: Sensory sensations (tingling, pins and needles, numbness, dead-feeling limbs, band-like tightness).
U: Unusual clumsiness, extremity weakness, leg dragging, muscle stiffness, limb heaviness.
A: All symptoms provoked and/or intensified by hyperthermia.
L: Lhermitte's sign. Flexion of the neck produces an electrical sensation that runs down the back and into the legs. This sign suggests intramedullary disease of the cervical cord.
