Seizure/Pseudo Seizure Disorder
A seizure is an event when you lose control of your body and convulse, possibly also losing consciousness. There are two types of seizures: epileptic and nonepileptic.
A brain disorder called epilepsy causes the first kind. Epilepsy disrupts the nerve activity in the brain, causing seizures. You can tell a seizure is epileptic if brain electricity monitoring during the event shows neurons misfiring.
Nonepileptic seizures are caused by something other than epilepsy — typically by psychological conditions. This means a brain scan won’t show a change during a nonepileptic seizure.
Dementia is the loss of cognitive functioning—thinking, remembering, reasoning and behavioural abilities to such an extent that it interferes with a person’s daily life and activities. These functions include memory, language skills, visual perception, problem solving, self-management, the ability to focus and pay attention. Some people with dementia cannot control their emotions and their personalities may change.
