How would you classify a seizure that is generalized and tonic-clonic in nature?

A seizure that is classified as generalized and tonic-clonic is characterized by the involvement of both hemispheres of the brain, leading to an initial phase of muscle rigidity (tonic) followed by rhythmic muscle contractions (clonic). This type of seizure is commonly associated with a loss of consciousness and is often what people refer to when discussing seizures in a general context.

Generalized tonic-clonic seizures typically present with the classic signs of stiffening and jerking movements and can often be followed by a postictal state of confusion or fatigue. The classification helps in guiding the treatment approach and understanding the underlying neurological conditions that may be present.

The other classifications mentioned do not fit this description: focal seizures involve specific areas of the brain, generalized absence seizures are brief lapses in consciousness without motor signs, and infantile spasms are a specific type of seizure that occurs in infants characterized by sudden flexor or extensor movements. Thus, the correct classification of a seizure that is both generalized and tonic-clonic is indeed a generalized tonic-clonic seizure.
