 Hi, this is Dr. Pramod Krishnan. I am a consultant neurologist at Manipal Hospital, Bangalore. I specialize in epilepsy. Seizures and epilepsy are of two types, two basic types, either focal or partial epilepsy and another category called generalized epilepsy. Now when seizure involves a part of the brain where the electrical abnormality involves a part of the brain, we use the term focal or partial seizure and the same applies to epilepsy as well. When it involves the entire brain right at the beginning, we use the term a generalized seizure or a generalized epilepsy. Now seizures may sometimes not produce any symptoms at all, in which case they are called subclinical seizures.
