Temporal lobe - seizures occurring here are associated with epigastric auras and automatisms. Other auras may be deja vu, or auditory, gustatory, or olfactory hallucinations. Other automatisms may be grabbing or finger plucking.
Both cerebral hemispheres is seen in generalised onset seizures, such as an absence seizure, which can also present with staring blankly into space. However, absence seizures do not have preceding symptoms such as aura (in this case, a preceding feeling of rising in his stomach) and are more commonly seen in children aged 3-10 years old. Up to 95% of patients with absence seizures become seizure-free in adolescence as well, making this diagnosis less likely.
Frontal lobe seizures are not associated with epigastric aura or automatisms. Patients tend to have head or leg movements and post-ictal weakness (known as Todd’s paresis), and a Jacksonian march, where muscle jerking moves proximally from a distal site (e.g. from one’s hand moving up their arm).
Occipital lobe seizures are associated with visual phenomena such as flashes and floaters
Parietal lobe seizures are associated with sensory dysfunction such as paraesthesia
