Case Report: Multiple Sclerosis and Amyotrophic Lateral Sclerosis

We present a case of concurrent multiple sclerosis (MS) and amyotrophic lateral sclerosis (ALS). Five other similar cases that have been reported in the literature are also reviewed. This rare and interesting case illustrates the importance of careful follow-up of patients with MS to avoid attributing every new neurologic symptom to the previously diagnosed disease and the maintenance of suspicion for unrelated emerging diseases.
