Neuropsychological disorders can also cause brain trauma. Epilepsy is an example of a neuropsychological disorder. Epilepsy interrupts the brain’s electrical flow. A person with epilepsy will experience a seizure which may be generalised or partial. A partial seizure only occurs in one part of the brain. There are two types of partial seizures; Simple and complex. A simple partial seizure has symptoms which are primarily motor or sensory. A complex partial seizure is associated with simple, repetitive behaviour. A generalised seizure involves the whole brain. There are two types of generalised seizures. These are grand- mal and petit-mal. The grand-mal is considered more severe as it is associated with loss of consciousness, loss or equilibrium
