Lateral medullary syndrome
Lateral medullary syndrome (pronunciation: lat-er-al med-ul-lar-y syn-drome), also known as Wallenberg's syndrome, is a neurological condition resulting from a stroke in the lateral part of the medulla oblongata. The syndrome is named after the Swedish neurologist Adolf Wallenberg, who first described the condition in detail.
Etymology
The term "lateral medullary syndrome" is derived from the location of the condition in the brain. The medulla oblongata is a part of the brainstem, and "lateral" refers to the side of this structure where the stroke occurs. The term "syndrome" is used to describe a collection of symptoms that occur together and characterize a particular abnormality or condition.
Symptoms
The symptoms of lateral medullary syndrome can vary depending on the exact location and extent of the stroke. Common symptoms include:
- Dysphagia (difficulty swallowing)
- Dysarthria (difficulty speaking)
- Vertigo (a sensation of spinning)
- Nystagmus (involuntary eye movement)
- Ataxia (lack of muscle control or coordination)
- Horner's syndrome (a group of symptoms including drooping eyelid, constricted pupil, and lack of sweating on one side of the face)
Diagnosis
Diagnosis of lateral medullary syndrome is typically based on the patient's symptoms and medical history, along with imaging tests such as a MRI (Magnetic Resonance Imaging) or CT scan (Computed Tomography scan) to confirm the presence and location of the stroke.
Treatment
Treatment for lateral medullary syndrome primarily involves managing the symptoms and preventing further strokes. This may include medications to control blood pressure and cholesterol, as well as physical, occupational, and speech therapy to help manage symptoms and improve quality of life.
