Narcolepsy - A sleep disorder characterised by sudden and uncontrollable attacks of sleep, cataplexy, sleep paralysis and hallucinations when going off or waking up from sleep.
Neonatal seizures - Seizures occurring in the first month of life.
Neural migration defects - Epilepsy is often associated with defects that occur during brain development when the cells are migrating out to the cerebral cortex.
Neural tube defects - Defects that occur during development of the brain and spinal cord such as spina bifida.
Neuroimaging - Production of pictures of the brain and/or spinal cord. It can include computerised tomography ( CT) scanning, Magnetic Resonance Imaging (MRI), Photon Emission Computerised Tomography (SPECT) and Positron Emission Tomography ( PET).
Neurological - Anything to do with the nervous system. Broadly the brain, spinal cord, nerves and muscles.
Neurologist - A specialist in the diagnosis and treatment of neurological disorders, including epilepsy. Paediatric Neurologists see children.
Neuron(e) - The nerve cells of the brain and nervous system.
Neurontin - See Gabapentin.
neuroplasticity - The brain's ability to change and reorganise itself by forming new neural connections throughout life. Neuroplasticity allows the neurons (nerve cells) in the brain to compensate for injury and disease and to adjust their activities in response to new situations or to changes in their environment.
Neuropsychologist - A psychologist with expertise in the field of the relationship between the brain and behaviour. Test and assessment techniques are used to diagnose specific cognitive and behavioural deficits. This is important in determining where seizures may arise.
Neuropsychology - The branch of psychology that deals with the relationship between the brain, and cerebral or mental functions such as language, memory, and perception.
Neurosurgeon - A surgeon who operates on the brain, spinal cord, spinal column and nerves.
Neurotransmitter - Chemicals produced by nerve cells, necessary for the transportation of electrical signals in the nervous system.
Night terrors - A sleep disorder occurring mainly in young children. During sleep the child suddenly sits up, screams and appears terrified, but is not actually awake. They are usually inconsolable and will resume sleep after 10-20 minutes with no memory of the event in the morning.
Nocturnal Seizures - Seizures that occur during sleep.
Non-epileptic seizures - See psychogenic non-epileptic seizures (PNES).
Non-motor - where there is no physical signs such as motion or movement
