Worster-Drought syndrome

Worster-Drought syndrome (WDS), also known as congenital suprabulbar paresis or congenital perisylvian syndrome, is a form of cerebral palsy primarily affecting the muscles of the mouth, tongue, and soft palate (the bulbar muscles). It is classified under ICD-10 as G80.8 (other cerebral palsy). WDS is considered the most common form of cerebral palsy that is frequently underdiagnosed. The condition results from damage or abnormal development of the perisylvian regions of the brain, which control voluntary movements of the face, mouth, and throat. The hallmark features of Worster-Drought syndrome include difficulties with speech (dysarthria), swallowing (dysphagia), and drooling due to weakness or impaired voluntary control of the tongue, lips, pharynx, and soft palate. Affected individuals often present in infancy or early childhood with feeding difficulties, and speech development is typically delayed and characterized by nasal speech due to palatal weakness. Seizures (epilepsy) occur in a significant proportion of patients, and mild to moderate learning difficulties may be present, though intelligence can be normal. Some individuals also experience mild limb involvement, particularly affecting fine motor skills in the upper limbs. There is no cure for Worster-Drought syndrome, and management is supportive and multidisciplinary. Treatment typically involves speech and language therapy, which is central to improving communication abilities. Occupational therapy and physiotherapy may be needed for associated motor difficulties. Drooling may be managed with medication (such as anticholinergic drugs) or surgical interventions. Seizures are treated with standard antiepileptic medications. Feeding difficulties may require dietary modifications or, in severe cases, gastrostomy. Early diagnosis and intervention are important to optimize developmental outcomes.
