funtional recovery after trauma

When does stroke occur

When part of brain cut off from blood supply

• blockage cutting off blood supply

• Billed in or around brain

• Tumour growing and cutting off blood supply

What is a real world study 2)

JODY MILLER

Suffered from severe eplispey in one hemisphere

Suggest children have higher ability to recover after brain injury - supports neural plasticity

Sarah Scott Broca’s area - over time had functional recovery

WHAT system is it to ideniftfy a stroke

FAST

• face drooping on one side

• Arm - not able to move

• Speech - problems talking

• Time - important to get help quickly

Why is functional recovery important

Stroke victims could regain functions of amities that had been lost following damage caused by stroke

Found that other parts of brain can take over function of damaged areas

What is one way of functional recovery that is to do with ABC who discovered it

Neuronal unmasking

• dormant synapses become used to help regain lost functions

• Over time these help create new structures and functions

• WAL - first to identify

• If AB had a damaged connection - if previously unused connection exists to a diff neuron (C) then - A would strength connection to c AND C would strengthen connection to B

• HEBBS theory - unused connection will get stronger over time - some o al function can be regained

• Slow process

What’s second mechanism

AXONAL SPROUTING

Cells next to a lesion sprout extra axons to help make new connections and recover from damage

DELLER - help explain some of recovery of lost function

Sprouting stays within a small area of original cell

Issue with axonal sprouting is that Deller also found that might contribute to

What does TAJIRI study show

When implanted stem cells into injured Brian of a rat - stem cells migrate towards injury and turn into n ew neurons

Suggest stem cells could be used to treat brain damage in humans

What does SCHNEIDER FIND

Individuals with higher levels of education

More likely to be able to regain more abilities through functional recovery

Concluded that COGNITIVE REERVE - built through education - allows brain to better adapt afte injury
