Thanks for the answeres. Partial seizures start locally and have clinical and electrographic features that indicate onset from a single unilateral brain region.Primary generalized seizures appear to arise from both cerebral hemispheres at once.The manifestations focal seizures depend on the area of the brain involved.The more restricted the brain region involved,the more limited the symptoms and less likely that consciousness will be impaired. Localised seizures may then spread to adjacent areas of contralateral or more distant regions through thalamocortical and interhemispheric pathways,eventually resulting in secondary generalized seizures. "Aura is an ictal menifestation"

partial seizures originate from a paroxysmal discharge in a focal area of cerebral cortex generalised seizures is abnormal electrical discharges originate from the diencephalic activating system and spread continuously to all areas of brain.

Partial seizures are preceded by different kinds of aura representing the site of origin in the hemisphere. It is also termed localisation related epilepsy. There is no preceding aura in generalized seizure per se.
Aura, automatism, focality, preserved awareness, previous history of brain insult favouring focal sz Myoclonus , family history, loss of awareness, frequent fall suggest generalized sz
