A nurse is caring for a client at an outpatient clinic. For each assessment finding, click to specify if the finding is consistent with amyotrophic lateral sclerosis (ALS) or multiple sclerosis (MS). Each finding may support more than 1 disease process or none at all. There must be at least 1 selection in every column. There does not need to be a selection in every row.

Rationale • Genitourinary findings: Intermittent sensations of "squeezing or spasm" in the bladder or urinary tract are typical in multiple sclerosis due to autonomic nervous system involvement and demyelination affecting bladder control. These symptoms are less common in ALS, which primarily affects motor neurons without early autonomic involvement. • Report about gait: Episodes of leg weakness and balance issues can occur in both ALS and MS. ALS causes progressive motor weakness affecting gait due to upper and lower motor neuron degeneration. MS can cause intermittent gait disturbances from demyelination in the central nervous system, often with exacerbations and remissions. • Vision disturbance: Intermittent double vision is consistent with MS, reflecting demyelination of cranial nerves or the optic pathways. Visual symptoms, including diplopia or optic neuritis, are hallmark early signs of MS. ALS typically does not involve vision, making this symptom specific to MS. • Energy level: Fatigue lasting more than 4 months aligns with MS, which frequently causes persistent fatigue due to both neurological dysfunction and immune-mediated inflammation. ALS may lead to fatigue later in disease progression, but early chronic fatigue is more characteristic of MS.
