• CTE is a progressive, degenerative and fatal brain disease associated with repeated blows to the head over a long period of time
• thalamus is connected with structures of the limbic system, which is involved in the formation and storage of memories
• CTE can't be diagnosed before death due to CTE diagnosis requiring evidence of degeneration of brain tissue and deposits of tau protein that can only be seen after death
• hindbrain - pons


  the pons help transfer neural message between various parts of brain and the spinal cord
• pons are involved in sleep and arousal and coordination of some muscle movements
• loss of motor skills due to damage to cerrebellum
• cerebellum helps coordinate voluntary movement and balance by relaying motor information to and from cerebral cortex
• cerebellum role in motor learning

  motor skills are improved by practise, practise involves voluntary movement and balance, in order to get better, motor learning has occurred
• damage to cerrebellum

  loss of motor skills due to head trauma that result in damage to cerrebellum
• limbic system located on either sides of thalamus
• limbic main function is to process and regulate memory and emotion
• damage to limbic system and structure can result in a form of amnesia
• memory loss occurrence anytime after a TBI is known as a 'post traumatic amnesia' the seriousness of this diagnosis depends on the severity of the TBI
• thalamus role in thinking and memory

  thalamus is connected with structures of limbic system, which are involved in the formation and storage of memories
