Abstract:
Basilar artery occlusion is a devastating but treatable form of ischaemic stroke with high morbidity and mortality rates. The diagnosis is often challenging due to considerable heterogeneity of clinical signs and symptoms. We report a case of an acute basilar artery occlusion presenting with decreased level of consciousness associated with rhythmic tonic movements of the four extremities, mimicking seizure activity. The patient was treated with intravenous thrombolysis and subsequently gained good recovery. Awareness of this entity is required to recognise this potentially treatable, but otherwise devastating seizure mimic.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
Secondary Spinal Cord Injury llI: Pathophysiology
Hemorrhagic Stroke ll: Pathophysiology
