Symptom 4: Tremors – A Shaky Situation
The onset of tremors is another potential symptom of spinocerebellar ataxia. Unlike the “resting tremors” commonly seen in conditions like Parkinson’s disease, SCA typically causes “action or intention tremors.” These occur during the voluntary movement of a muscle, such as reaching for an object or moving a body part.
The tremors might start subtly, with a slight shaking during precise movements, such as threading a needle or writing. Over time, the tremors could become more prominent and interfere with a wider range of activities. As the condition progresses, individuals might notice that the tremors become more severe when they try to speed up their movements or when they’re nearing their target during a reaching movement.
Tremors can also occur in the head and voice, affecting speech and making the voice sound shaky. This, combined with dysarthria, can further complicate communication.
It’s worth noting that while tremors can be disconcerting, there are treatment options available, including medications and physical therapy, which can help manage this symptom. However, the presence of tremors should prompt a consultation with a healthcare professional, as they can be indicative of several neurological conditions. (4)
