Symptoms vary based on the type of seizure. They also can range from mild to severe. Seizure symptoms may include: 
Temporary confusion.
A staring spell.
Jerking movements of the arms and legs that can't be controlled.
Loss of consciousness or awareness.
Cognitive or emotional changes. They may include fear, anxiety or a feeling that you've already lived this moment, known as deja vu.
 Health care providers typically classify seizures as focal or generalized. Seizures are classified based on how and where the brain activity causing the seizure began. If providers don't know how the seizures began, they may classify the seizures as unknown onset. Focal seizures Focal seizures result from electrical activity in one area of the brain. This type of seizure can occur with or without loss of consciousness: 
Focal seizures with impaired awareness. These seizures involve a change or loss of consciousness or awareness that feels like being in a dream. People having these types of seizures may seem awake but they stare into space and don't respond to their environment. They may perform repetitive movements such as hand rubbing, mouth movements, repeating certain words or walking in circles. They may not remember the seizure or even know that it occurred.

Focal seizures without impaired awareness. These seizures may alter emotions. They also may change the way things look, smell, feel, taste or sound. But the seizures don't cause a loss of consciousness.
During these types of seizures, people may suddenly feel angry, joyful or sad. Some people have nausea or unusual feelings that are hard to describe. These seizures may result in trouble speaking and involuntary jerking of a body part such as an arm or a leg. They also may cause sudden sensory symptoms such as tingling, dizziness and seeing flashing lights.

 Symptoms of focal seizures may be confused with other disorders of the brain or nervous system. They include migraine, narcolepsy or mental illness. Generalized seizures Seizures that appear to involve all areas of the brain from the time they start are called generalized seizures. Different types of generalized seizures include: 
Absence seizures. Absence seizures, formerly known as petit mal seizures, often occur in children. Absence seizures typically cause a person to stare into space or make subtle body movements such as eye blinking or lip smacking. They usually last for 5 to 10 seconds. These seizures may happen up to hundreds of times a day. They may occur in clusters and can cause a brief loss of awareness.
Tonic seizures. Tonic seizures cause stiffening of the muscles. These seizures usually affect muscles in the back, arms and legs. People who experience these seizures may lose consciousness and fall to the ground.
Atonic seizures. Atonic seizures, also known as drop seizures, cause a loss of muscle control. People having this type of seizure may suddenly fall down or drop their head.
Clonic seizures. Clonic seizures are associated with repeated jerking muscle movements. These seizures usually affect the neck, face and arms on both sides of the body.
Myoclonic seizures. Myoclonic seizures usually appear as sudden brief jerks or twitches of the arms and legs. There is often no loss of consciousness.
Tonic-clonic seizures. Tonic-clonic seizures, previously known as grand mal seizures, are the most dramatic type of epileptic seizure. They can cause a sudden loss of consciousness, body stiffening and shaking. They sometimes cause people to lose control of their bladder or to bite their tongue. They may last for several minutes. Tonic-clonic seizures also may start as focal seizures that then spread to involve most or all of the brain.
