Apraxia of eyelid opening is nonparalytic inability to open the eyes at will in the absence of visible contraction of the orbicularis oculi muscle. It is known that apraxia of eyelid opening is a feature of extrapyramidal diseases. We experienced a case with apraxia of eyelid opening after right thalamic infaction. We suggest that dysfunction of supranuclear control of the levator palpebrae superioris may be a pathophysiologic mechanism in apraxia of eyelid opening.

Apraxia of speech (AOS) is the impairment of motor programming. However, the exact nature of this deficit remains unclear. In particular, AOS without other speech-language deficit is called pure AOS, but it is very rare. When diagnosing AOS, the characteristic of articulation is considered a crucial criterion, which has been proposed for differentiating AOS from phonological and dysarthric disorders. The present study reports on pure AOS in a 37-year-old right-handed male after a left insular, front, temporal infarction. This report may be useful for further AOS study and diagnosis in the clinical setting.

PURPOSE: To evaluate the natural clinical course of sporadic congenital oculomotor apraxia associated with ataxia. METHODS: In a retrospective study from June 1994 to March 2004, 3 patients with sporadic congenital oculomotor apraxia associated with ataxia were evaluated. Oculomotor apraxia and ataxia were checked. RESULTS: The three patients with sporadic congenital oculomotor apraxia associated with ataxia showed a decrease in head thrust which can be found specifically in oculomotor apraxia, and an improvement of oculomotor apraxia and ataxia over the 10-year observation period. CONCLUSIONS: A favorable natural clinical course can be expected in a case of sporadic congenital oculomotor apraxia associated with ataxia in the absence of any clinical evidence of inheritance or genetic abnormality.

Agenesis of the cerebellar vermis, episodic hyperpnea alternating with apnea, abnormal eye movement, ataxia, and psychomotor retardation are shown in Joubert syndrome. This rare syndrome is inherited as an autosomal recessive trait with variable expression. We report the first cases of Joubert syndrome in Korea, to our knowledge, which showed ocular motor apraxia and agenesis of the cerebellar vermis by Magnetic Resornance Image. From these two cases, we describe the correlation between the cerebellar vermian dysfunction and the ocular motor apraxia.

The treatments of AOS have been debated since the late 1960s. Despite a considerable amount of study of intervention approaches to AOS, the effectiveness and efficacy of the treatment of AOS is still unclear. This study investigates the effect of motor learning guided (MLG) approach on individuals with AOS. Two individuals with AOS whose severity ranged from mild to moderate participated in this study. Two sets (each 20 utterance) of stimuli were created (based on high functionality) by the participants and their primary care-givers. Subjects were instructed to produce the target word three times with 4-second pause between each attempt. After 3 attempts, the experimenter provided knowledge of results (KR). Each target word was randomly selected from the written stimulus cards. The results showed that the mean scores of all the subjects increased during the sessions and this effect was transferred to the untrained target words.
