Sign 3. Slurred Speech – The Unsuspected Sign of ALS
Another common symptom of ALS is a change in speech patterns, including slurred speech, or what healthcare professionals call dysarthria. When the muscles responsible for speech are impacted by the disease, the result is a gradual, noticeable decline in clear, easy-to-understand speech.
Dysarthria, in ALS, is not merely a symptom—it’s a marker of how the disease is progressing and which motor neurons are being affected. Speech is a complex motor task that involves a wide range of muscles, all of which need to coordinate perfectly to produce clear, coherent speech. This makes dysarthria a useful tool for healthcare professionals in understanding the extent and progression of motor neuron involvement.
In the early stages of ALS, dysarthria may be subtle, and only those close to the person might notice it. Speech may become softer, or there might be slight hesitations or stutters.
As the disease progresses, the speech may become more noticeably slurred, and the person might speak more slowly, as it takes greater effort to articulate words. In severe cases, speech may become so unclear that it is difficult for others to understand.
It’s important to note, however, that slurred speech can also be a symptom of a number of other conditions, including stroke, brain injury, or even side effects from certain medications. So while slurred speech warrants investigation, it doesn’t definitively mean that the person has ALS.
However, if slurred speech is accompanied by other symptoms of ALS, particularly muscle weakness or twitching, it becomes more critical to consult a healthcare professional. An early diagnosis can lead to early treatment, which may slow the progression of the disease and improve quality of life.
Living with ALS is a journey, and symptoms like dysarthria can affect a person’s self-esteem and social interactions. But remember, many people with ALS continue to lead fulfilling lives, supported by adaptive technologies, therapies, and the love and understanding of their families and communities. (3)
