The Importance of Dysarthria in Differential Diagnosis: A Case Study
Dysarthria results from lesions in the central nervous system, the peripheral nervous system, or both. Therefore, dysarthria is associated with a wide variety of neurological pathologies and presents in a variety of forms. In a given clinical neurological picture, disturbance of speech is usually relegated towards the bottom of the list of symptoms; its presence may be acknowledged but granted little importance for diagnosis and usually for the rehabilitation process as well. The purpose of this chapter is to present a clinical case study illustrating the potential importance of dysarthria in the differential diagnosis of a neurological condition. Our patient was diagnosed with Binswanger’s disease (BD), but the diagnosis did not match the dysarthria or some aspects of the clinical neuropsychological symptomatology. Subsequently, and in part due to the dysarthrie signs, the diagnosis of amyotrophic lateral sclerosis (ALS) was added.
