    What happens

    What you experience, and what people will see, during a focal seizure depends on which part of the brain is affected. This is because different parts of the brain control our movements, body functions, feelings and reactions.

    The lobes in your brain

    Focal seizures can start in different parts of the brain, and create a range of symptoms. Click or tap the markers to find out more.

    The lobes of the brain labelled

    Frontal lobes

    Focal seizures starting in the frontal lobes are common. The frontal lobes are responsible for many functions such as: personality, behaviour, movement, concentration and problem solving.

    Parietal lobes

    Seizures starting in the parietal lobe often spread to involve other lobes. The parietal lobes are responsible for: processing language, signals from our senses and spatial awareness.

    Temporal lobes

    Focal seizures starting in the temporal lobes are common. The temporal lobes are responsible for many functions, such as hearing, speech, memory, and emotions.

    Occipital lobes

    Seizures starting in the occipital lobes often spread to involve other lobes. The occipital lobes are responsible for vision.

    After the seizure

    How people feel after a focal seizure varies.

    You might feel fine and be able to get back to what you were doing straight away. Or you could feel confused or tired for some time afterwards. You may want to sleep afterwards to help you recover.

    Sometimes people experience a temporary weakness or can’t move part of their body after a seizure. This is called Todd’s paresis or Todd’s paralysis. It can last from a few minutes to a few days before going away.
