10. Muscular Weakness – The Fading Strength
Muscular weakness, a common symptom of many neurological disorders, is also a significant part of OPCA’s symptom profile. In contrast to muscular rigidity, which we discussed earlier, muscular weakness is characterized by a decrease in muscle strength, making it harder to perform activities that require muscle power.
Muscle weakness in OPCA can manifest in several ways, depending on which muscles are affected. If leg muscles are affected, an individual might find it challenging to walk or stand. If the muscles in the arms are weak, tasks that require manual dexterity, such as writing or opening a jar, might become difficult.
Muscle weakness can also affect muscles involved in swallowing and speech, contributing to dysphagia and dysarthria, which we discussed earlier. The impact of muscle weakness on these functions further underscores the interrelated nature of OPCA symptoms and the broad influence of this condition on various bodily systems.(10)
