An anatomical change that multiple sclerosis has on the nervous system is cause the patient to have muscle spasms. Patients with this condition will most likely encounter this debilitating symptom. Spasticity can be caused by either deterioration of the axons or impairment of demyelinating plaques on the descending motor pathways (De Sa et al., 2011). In addition to that, increased muscle tone and decreased muscle dexterity are observed from this change (Boissya and A Cohen, 2015). Muscle spasms can reduce the patient's ability perform daily activities which can decrease life expectancy and quality of life. Another anatomical change is tremors, which are described as involuntary quivering and twitching motion. The extent of damage to the connections
