Is there always a clearly identifiable cause of dysarthria?

Dysarthria is a motor speech disorder resulting from neurological injury that affects the muscles involved in speech. While it can be associated with various conditions, such as stroke, brain injury, or neurological diseases like Parkinson’s or amyotrophic lateral sclerosis (ALS), there is not always a clearly identifiable cause for every case of dysarthria. Some individuals may experience dysarthria as a result of a complex interplay of factors, and in certain situations, the underlying cause may remain unknown or undiagnosed. This complexity highlights that each case can vary significantly, which is why the statement asserting that a clearly identifiable cause is always present is incorrect.
