Week 12 Flashcards
a response by an individual that delivers something unpleasant to another person
aggression
Characterized by recurrent headaches, usually accompanied by nausea, vomiting, photophobia or phonophobia
migraines
increased blood flow in brain distends blood vessels, which exerts pressure on surrounding tissue
vascular theory of headaches
the hypothetical structure that when activated leads to migraines—one possibility is the Raphe nucleus
migraine generator
Occurs when the brain’s blood supply is interrupted by bleeding or blockage of blood vessels
strokes
serotonin, dopamine, GABA, noradrenaline
neurotransmitters involved in aggression
Bleeding in the brain: results from high blood pressure (hypertension) or structural defects
cerebral hemorrhage
Blockage of CNS vasculature leads to_____, or low oxygen levels (80% of all strokes)
Ischemia
material that blocks blood vessel without moving from its point of origin
thrombosis
material that passes into smaller and smaller vessels until it forms a blockage
embolism
physical damage to the brain; causes include traffic accidents, gunshot wounds, falls, etc.
traumatic brain injury (TBI)
Occur in response to blow to the head resulting in “impulsive” force transmitted to the brain
concussion
Cognitive symptoms: lack of concentration, reduction in processing speed, attention, and memory
Physical symptoms: headache, depression, irritability
post-concussion syndrome (PCS)
Permanent damage from repeated mild head injuries, resulting in slurred speech, memory impairment, personality changes, lack of coordination, and Parkinson-like syndromes
chronic traumatic brain injury (CTBI)
Once thought only to affect boxers. Now found in many contact sports including: American football, rugby, ice hockey, bull riding, stunts, rodeo
chronic traumatic encephalopathy
