Tegretol -  Also known as Teril or Carbamazepine. See Carbamazepine.
Telemetry -  video EEG – A technique for recording seizures on video with simultaneous EEG; changes in behaviour can be correlated with changes in the EEG; very useful diagnostic tool for epilepsy.
Temporal lobe -  The lobes in the brain situated beneath the temples. Seizures commonly originate in this region in the focal epilepsies. The temporal lobe is associated with memory, speech, language, learning and behaviour.
THC -  Tetrahydrocannabinol is the main component of the cannabis (marijuana) plant that affects brain function.
Tiagabine -  Also known as Gabitril. Used in partial and secondarily generalised seizures.
Tic -  Repeated involuntary contractions of muscles, such as sniffing, clearing the throat, rapid head jerks or eye blinks; may be under partial voluntary control (can be temporarily supressed). Not epilepsy.
Todd’s paralysis -  Weakness or paralysis occurring in one limb or one side of the body after a seizure. Todd’s paralysis after a seizure is usually resolved in one or two hours but may, on occasion, continue for several days.
Tonic -  Increased muscle tone, stiffening of the muscles
Tonic seizure -  Also termed ‘drop attack’. Muscles of the body briefly stiffen simultaneously, and if standing, the person will crash to the ground. These often happen in sleep. More likely to be seen in people with complex epilepsy syndromes.
Tonic-clonic seizure -  Previously called “Grand Mal” and also termed convulsion or fit. These are the most universally recognised seizures. They often begin with a sudden cry and loss of consciousness. The body becomes quite stiff (tonic) shortly followed by jerking of the muscles (clonic). The seizure usually lasts no more than 2 minutes and is followed by a period of confusion, agitation or sleep. Headaches and soreness are common afterwards.
Topirimate -  Also known as Topamax. Used in focal and generalised onset seizures. Also used in Lennox -Gastaut syndrome.
triggers -  Identifiable causes for seizure activity in an individual often referred to as seizure triggers.
Tuberous sclerosis (Bourneville’s syndrome) -  Is an inherited condition which benign tumours affect the brain, eyes, skin and internal organs. Epilepsy occurs in 80% of cases, and the type of seizures are strongly age related.
Tumour -  A growth of abnormal tissue characterised by progressive, uncontrolled proliferation of cells.
