What is the defining criteria of a TBI?
An alteration in brain function or other evidence of brain pathology caused by an external force and characterized by: 1) any period of loss of consciousness, 2) any memory loss for the events immediately before or after the injury, 3) any neurological deficits, 4) any alteration in mental state at the time of the injury
Are primary brain tumors more common in adults or children?
Children
What is kindling? automatism? aura?
Kindling - the development of an epileptogenic network by exposure to recurrent seizures
Automatism - a more or less coordinated, repetitive motor activity usually occurring when cognition is impaired and for which the subject is usually amnestic afterwards. This often resembles a voluntary movement and may consist of inappropriate continuation of ongoing preictal activity
Aura - subjective sensory phenomena that precedes a seizure and may serve as a warning that a seizure may be imminent
How do clonic seizures present? Tonic? Myoclonic?
Clonic: brief rhythmic jerking movements of muscles affecting both lower and upper extremities
Tonic: sudden onset of bilateral tonic extension or flexion of the head, trunk, or extremities
Myoclonic: quick jerks, involving symmetric movements of the head, distal limbs, or axial musculature
Do late life or early life psychiatric symptoms increase the risk of developing dementia?

Temporal lobe epilepsy can cause what symptoms?
Aura that involves wide eyed stare followed by oral automatisms (lip smacking, swallowing, or chewing movements) and/or automatisms of the upper extremities (pill rolling movement or picking with hands) and altered consciousness.
Neuropsychological impairment is common, but lateralization is noted depending on location of the seizure. Deficits in general cognitive ability, academic achievement, language, memory, attention, executive functioning, motor skills, and visuospatial functioning
