Head | Neurology | Seizures (Symptom)
A seizure is a sudden episode of abnormal electrical activity in the brain. Recurrent seizures occur in epilepsy. An epileptic seizure, occasionally referred to as a fit and is defined as a transient symptom of abnormal excessive or synchronous neuronal activity in the brain. It can manifest as an alteration in mental state, tonic or clinic movements, convulsions, and various other psychic symptoms (such as déjà vu). Seizures can occur from infancy to your later years in life.
Not all seizures look the same. For instance, generalized tonic clinic seizures are characterized by jerking and stiffening of the entire body, whereas in absence seizures, the individual might appear as if they are staring off into space. There are also other seizures that might involve the twhiching of a finger or one area of the body.
There are many causes of seizures. For instance, young children and babies are more susceptible to seizures under certain conditions, such as having a fever or too much water. On the other hand, strokes and neurodegenerative disorders, like Alzheimer’s disease, may make an older person more susceptible to experiencing a seizure. Causes of seizures also include head injury, brain tumor, infection, metabolic disturbances, withdrawal in alcohol dependence, or hereditary alcohol intolerance.
