What sensation often precedes an epileptic attack?

The sensation that often precedes an epileptic attack is an aura. An aura is a focal neurological symptom that occurs in some individuals with epilepsy before the onset of a seizure. It can manifest in various ways, including sensory experiences such as unusual smells, visual disturbances, or feelings of déjà vu. The presence of an aura provides a crucial warning sign to individuals, letting them know that a seizure may be imminent.

Understanding the nature of the aura can help individuals manage their condition more effectively and prepare themselves for the possibility of a seizure. For example, some people may anticipate a seizure and have time to move to a safe location or seek assistance. The characteristics of the aura can vary significantly among individuals, which is important for distinguishing between different types of seizures and personalizing treatment approaches.
