Bulbar Onset Amyotrophic Lateral Sclerosis in an African American Older Adult.

Background

Amyotrophic lateral sclerosis (ALS), a fatal neuromuscular disease, affects the motor tracts and anterior horn cells of the spinal cord, causing both upper and lower motor neuron dysfunction. ALS typically involves progressive peripheral weakness and mobility issues. Case Report: An African American male in his early 70s presented to his primary care provider (PCP) with bulbar weakness and urinary tract symptoms. At presentation, and even later in the disease course, he ambulated well and did not report any limb issues. After some months of worsening symptoms of dyspnea, dysarthria, dysphagia, and urinary incontinence, a diagnosis of ALS was made via collaborative work between the PCP, a medical student, and various medical specialists including a neurosurgeon and neurologist. Because of the absence of limb abnormalities, the patient had difficulty accepting a diagnosis of ALS, thus delaying treatment onset.

Conclusion

Clinicians must consider the patient's presentation holistically so that they do not miss insidious, complex, or unique presentations. ALS can present with bulbar symptoms early in the disease course with no upper motor neuron/lower motor neuron involvement. Older adult African American males can present with ALS. Mistrust of health care systems and resistance to science based on religious beliefs can impact patient acceptance of diagnoses and engagement in treatments. Having a long-term relationship with a PCP who also represents the patient's community can influence patient willingness to accept diagnoses, especially those that are life-limiting.
