When people think about seizures, they often think of convulsive seizures, where somebody loses consciousness, their body goes stiff and they fall to the floor with their limbs jerking.Ĭonvulsive seizures are rarely experienced by people living with a brain tumour and sometimes referred to as fits – but are more correctly called tonic-clonic seizures. Both of these can interfere with the normal electrical activity in the brain. Or they may be due to an imbalance of chemicals in the brain caused by the tumour. In brain tumour patients, seizures may be related to cells around the tumour that have developed abnormally. There are more than 40 types of epilepsy of which brain tumour-related epilepsy (BTRE) is one. if your tumour is in one of the lobes of the cerebrum (cerebral cortex) or the meninges (the membranes that cover and protect the brain and spinal cord).Įpilepsy is the tendency to have repeated seizures, so it’s usually only diagnosed after you’ve had more than one seizure.
They do this by passing electrical signals or messages to each other. Our brains have billions of nerve cells which control the way we move, think and feel.
