Multiple sclerosis	1996-01-31		.txt	text/plain	13844	885	47	Abnormalities in the cerebral hemispheres are frequently periventricular in distribution and only occasionally correlate with specific symptoms or signs.6,7 The accumulation of lesions in the frontal lobes is associated with a decline in memory.8 In addition, a change in the number of lesions on cranial MR images correlates with a change in overall clinical status as measured with standard scales.g Observations made with MRI are having a marked impact on both our basic knowledge of MS and on therapeutic trialsJo MRI studies will provide considerable insight into the natural history of the disease and will be an excellent independent variable in future clinical trials. Signs and symptoms that commonly occur as MS progresses include vertigo, tremor, incoordination, increasing spasticity, depression, mood swings, cognitive abnormalities, impotence or other sexual dysfunction, weakness, Lhermitte's sign, gait abnormalities, constipation, urinary incontinence, optic nerve pallor, fatigue, quadriparesis, dysarthria, loss of upper extremity coordination, and dysesthetic pain (Table 1) .	./cache/cord-331268-kzy33hdb.txt	./txt/cord-331268-kzy33hdb.txt
