Final answer:
Dysphasia can be caused by various connective tissue disorders such as Fibrodysplasia ossificans progressiva, Pseudoxanthoma elasticum, and Systemic lupus erythematosus, which can affect swallowing through different pathophysiological mechanisms.
Step-by-step explanation:
Dysphasia is a medical condition that refers to difficulty in swallowing and can be associated with various connective tissue diseases. Some examples of connective tissue disorders that can cause secondary dysphasia include Fibrodysplasia ossificans progressiva, an inheritable disease where connective tissue is abnormally ossified into bone, and Pseudoxanthoma elasticum, which affects the skin, eyes, and cardiovascular system due to the calcification of elastic fibers. Additionally, systemic conditions like Systemic lupus erythematosus, which has autoimmune origins and predominantly affects young women, can also lead to dysphasia through its multisystem effects. These diseases may compromise the musculature or structural integrity required for the normal swallowing process, thereby resulting in dysphasia.
