Previously known as grand mal seizures, which seizure type results in loss of consciousness and convulsive movements?

The seizure type that was previously known as grand mal seizures is characterized by loss of consciousness and convulsive movements. This type of seizure is classified as a tonic-clonic seizure. During a tonic-clonic seizure, the person typically experiences two main phases: the tonic phase, in which the muscles stiffen and the individual loses consciousness, followed by the clonic phase, where there are rhythmic jerking movements. This comprehensive seizure activity affects the whole brain and leads to noticeable physical manifestations, making it distinct from other types of seizures.

In contrast, absence seizures involve brief episodes of staring or loss of awareness without convulsive movements, and they do not lead to loss of control over muscle function as seen in tonic-clonic seizures. An aneurysm is a serious medical condition involving blood vessels in the brain and is not classified as a seizure type. The term 'seizure' alone is too broad and does not specify the characteristics associated with the tonic-clonic seizure. This specificity makes tonic-clonic seizures the correct choice in this question, as they align directly with the definitions and symptoms described.
