Seizures and convulsions are examples of neurological events that result from abnormal electrical activity in the brain. They can manifest as sudden, uncontrolled movements or changes in behavior, consciousness, or sensations. Seizures can be classified into various types, including focal and generalized seizures, while convulsions typically refer to the violent shaking movements associated with certain types of seizures, such as tonic-clonic seizures. Both conditions can be symptoms of underlying medical issues, such as epilepsy or brain injury.
During an epileptic seizure a person can have convulsions. There are different types of seizures, not all involve convulsions.
Convulsions/seizures
There are several types of convulsions, primarily categorized into two main groups: generalized and focal. Generalized convulsions affect both sides of the brain and include types like tonic-clonic seizures, absence seizures, and myoclonic seizures. Focal convulsions, on the other hand, originate in one specific area of the brain and can manifest as simple partial seizures or complex partial seizures. Each type varies in symptoms and duration, reflecting different underlying neurological conditions.

Anticonvulsant drugs are medicines used to prevent or treat convulsions (seizures).
The types of seizures often change. In most cases, the drop seizures subside. They are replaced by partial, complex partial, and secondarily generalized convulsions.
No. Seizures can be 'grand mal' which involve the tonic-clonic muscle movement you describe as convulsions. 'Petit mal' seizures can be absence seizures, most often seen in children, where the patient seems catatonic for a brief period. Partial seizures can involve only one small body area, and some seizures consist of just a recurrent tic which can evolve into a larger seizure. Even a hiccup is believed to be a type of mild seizure.
Epilepsy - a brain disorder in which a person has repeated seizures (convulsions) over time.
