Malfunctioning Brains Flashcards
What are some common causes of brain damage?
Head injuries, stroke, anoxia (damage due to lack of oxygen), concussions
What is a concussion?
Where a person experiences loss of consciousness for a period of time, may lead to temporary or permanent memory loss or permanent brain damage.
What effect can mild concussions have?
Can disrupt the process of memory consolidation and cause retrograde amnesia (forgetting events that take place prior to head injury) as well as anterograde amnesia (Inability to remember events that occurred after the trauma).
Boxers receive many hits to the head throughout their careers. What effects may this have on their brain?
Can lead to brain damage and result in a range of impairments such as poor memory, permanently slurred speech and other cognitive deficits. This condition is referred to as an athlete being ‘punch-drunk’
What is adaptive plasticity?
The ability of the brain to change, adapt and grow throughout life. It enables older brain to be modified through experience or learning.
What influences the development of synapse in adolescence?
Adults will continue to develop synapses as a result of learning and new experiences: stimulating experiences and environment shape the construction and remodelling of a person’s brain throughout life.
Stem cells will continue to create what?
They continue to make neurons, to enable the brain to adapt and cope with any new experiences
What is a factor that can keep the brain active?
Different cognitive activities, leaving the brain with more plastic throughout life.
Who was Cameron Mott and her case?
She had half her brain removed to stop her from suffering seizures, and since had a full recovery.
Cameron was having 10 seizures a day and she was losing her ability to speak. She was diagnosed with Rasmussen’s syndrome in 2007, which is a rare disorder that causes deterioration on one side of the brain, for cameron her right side.
The doctor’s believed it to be an effective surgery to remover half her brain, as she was a child, she had efficient plasticity, which enabled the other side of her brain to take over and control the function of the diseased half that’s removed.
After two years, Cameron walked out of the hospital after extensive physical therapy.

The Cameron Mott case:
She was a young child who had half her brain removed, due to suffering of continuous daily seizures and her decreasing ability to speak. Since the surgery she has made full recovery.
She initially was diagnosed with Rasmessen’s Syndrome in 2007, which is a rare disorder that causes deterioration on side of the brain, for Cameron, this was her right side. The treatment involved a hemispheretomy (removal of entire right side of brain), which was a 7 hr surgery.
Doctors’ believed that the procedure was appropriate for Cameron as she was a child with efficient plasticity, that would eventually adapt to take over the other side of the brain and control its function of the diseased half removed.
How long did it take Cameron to recover?
It took two days of complete immobilisation, then four weeks of intense physical therapy, before Cameron walked out of the hospital.
Does Cameron Mott face any issue prior to surgery?
She has had no more seizures, and now has a slight limp as her body is still learning to control her hands and legs, and she has losses some of her peripheral vision.
