A form of cerebral palsy with characteristics of congenital pseudobulbar (suprabulbar) paresis manifesting as selective weakness of the lips, tongue and soft palate, dysphagia, dysphonia, drooling and jaw jerking. Mean age at diagnosis is 6 years. The main clinical features are spasticity and limited movements around the mouth and throat from an early age, and brisk jaw jerks. Most cases are sporadic but several families with more than one affected member have been reported. Inheritance in these families appeared to follow an autosomal dominant pattern with variable expression and penetrance.
