[sociallocker]The differential diagnosis of Staring spells in children include Absence Seizures, Complex partial seizures and Non Epileptic Staring spells (Day-Dreaming, Inattention spells) The patient has complex partial seizures as evidenced by loss of consciousness during the episode and preceded by aura and followed by postictal state. Symptoms of Complex partial seizures vary massively among the patients. When starting spells are the only manifestation of complex partial seizures, it is important not to get confused with Absence Seizures. Absence seizures are a type of generalized seizures – hence, they are not preceded by Aura and there is no postictal state. Also, Absence seizures are very brief lasting only for few seconds (15 to 30 seconds) unlike complex partial seizures that may last several minute. These features will help differentiate a “True” absence seizure from a complex partial seizure.[/sociallocker]
