title: Barking seizure: acute episodes of barking in a 75-year-old previously healthy man.
abstract: A 75-year-old right-handed man was admitted to our emergency department complaining of recurrent episodes of involuntary 'barking' within the past 12h. The episodes had occurred after an initial two-minute attack from sleep involving tonic contraction of the upper extremities and jaw locking. By the time of admission, the patient had had a total of at least 7-10 'barking' episodes, each lasting 30-45 s. Seven months prior to his current admission, the patient had had a minor ischemic stroke causing mild left paresis, which had resolved completely. His awake EEG revealed a normal background pattern interrupted by runs of two per second slow waves mixed with low-voltage spikes in the left temporal lobe with a left mid-temporal emphasis. The patient was diagnosed with recurrent simple partial seizures, and treatment with intravenous valproic acid was initiated. He was discharged four days later without having experienced any further barking episodes. Atypical presentations of the epileptic seizures have been described in the literature, but ictal barking is very rare manifestation of epilepsy.
