Focal seizures with awareness reduced or lost: the person may experience strange feelings and awareness may be disturbed or lost. They may be unaware of their surroundings, be unable to respond when spoken to and their behaviour may appear unusual. This is also sometimes called a complex focal seizure. Some focal seizures can evolve, with electrical disturbance spreading to large regions of both sides of the brain. This can result in a focal seizure evolving into a convulsion, which may look very like a generalised tonic-clonic seizure Unclassified seizures Some seizures are unclassified, i.e. they don’t fit into any category. Others occur as part of a syndrome – a set of symptoms occurring together – particularly in childhood. 2/3 •Infections and fevers, e.g. meningitis, rubella, encephalitis • Benign and malignant tumours • Genetic factors, e.g. tuberous sclerosis • Dementia and neurodegenerative disorders, e.g. Alzheimer’s disease • Stroke, which can occur at any age • Parasitic infections, e.g. malaria (very rare in the UK, but an important cause of epilepsy in other parts of the world) Types of seizure There are two broad categories of seizure: 1. Generalised seizures In generalised seizures large areas on both sides of the brain are affected by the disruption and consciousness is often lost.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
