Pseudobulbar mutism is rarely attributed to bilateral discrete posterior limb internal capsule-medial globus pallidus infarction. Few cases of bilateral anterior choroidal (AchA) artery territory infarction have been reported. We present 8 patients with ischaemic stroke in this location and vascular distribution who have a characterizable syndrome. All had the abrupt onset of inability to speak, swallow or phonate, accompanied by varying degrees of facial diplegia, hemiparesis, hemisensory loss, lethargy, neglect and change in affect. The appearance of clinical signs depends upon the presence of a new infarct contralateral to an older lesion in mirror position. The pathogenesis and progression of neurological deficit appears to be intimately related to hypertension. The role of intrinsic intracranial vascular pathology related to diabetes mellitus, embolism of cardiac origin and atherosclerosis is currently undefined. The prognosis for recovery is poor. Half of our patients died within a year of onset of symptoms. Capsular pseudobulbar mutism is recognized by the abrupt appearance of neurological deficit consistent with internal capsular pathology and is confirmed by CT scan or MRI.

Disulfiram is known to produce toxic encephalopathy and peripheral neuropathy. The case of a 37-year-old alcoholic who attempted to commit suicide by taking 22.5 g disulfiram is described. During the first 6 days after the intoxication he was stuporous and had cerebellar ataxia and dysarthric speech. Then he became comatose, and as he recovered from coma, he showed peripheral neuropathy including diplegia faciei and severe tetraparesis. Denervation potentials were detected in both facial muscles and distal muscles of the upper and lower limbs, while conduction velocity was normal. Axonal degeneration was verified by sural nerve biopsy. In addition neurofilamentous axonopathy was documented. The recovery from his paresis lasted 2 years.
