Amyotrophic lateral sclerosis is a fatal neurodegenerative disorder with progressive deterioration of both upper and lower motor neuron functions. It is a rare disease with one study demonstrating a prevalence of 3.9 cases per 100,000 in the USA in the year 2010-2011. It is a fatal disease with most of the deaths resulting from respiratory failure. There is no cure of this illness with some evidence supporting an improved median survival by two to three months with Riluzole (one of the agents used for treatment). Not much is known about the possible etiologies of ALS, a few studies have shown a possible likely association of ALS with various malignancies. Here we present an interesting case of a 35-year-old female with a diagnosis of chronic myeloid leukemia for seven years presented with a sub-acute decline in her motor function.
