Avellis syndrome
Avellis Syndrome
Avellis syndrome (pronunciation: /əˈvɛlɪs/), also known as Avellis's syndrome, is a rare neurological disorder characterized by paralysis of the soft palate and vocal cords on one side of the body. The condition is named after the German neurologist Georg Avellis, who first described the syndrome in 1892.
Etymology
The term "Avellis syndrome" is derived from the name of Georg Avellis, who first identified and described the condition. The suffix "-syndrome" comes from the Greek word "σύνδρομο" (sýndromo), meaning "concurrence of symptoms" or "running together".
Symptoms
The primary symptoms of Avellis syndrome include dysphagia (difficulty swallowing), dysphonia (difficulty speaking), and hoarseness. These symptoms result from the paralysis of the soft palate and vocal cords on one side of the body.
Causes
Avellis syndrome is typically caused by a lesion in the medulla oblongata, a part of the brainstem that controls many vital functions. This lesion can result from various conditions, including stroke, tumor, or infection.
Diagnosis
Diagnosis of Avellis syndrome is based on the patient's symptoms and a physical examination. Additional tests, such as MRI or CT scan, may be used to identify the location and cause of the lesion in the brainstem.
Treatment
Treatment for Avellis syndrome primarily involves managing the symptoms and treating the underlying cause of the condition. This may include speech therapy for dysphonia and dysphagia, and medical or surgical treatment for the underlying condition causing the syndrome.
