disorders

• 3 ways to image the brain

  • MRI
  • CT scan
  • EEG scanner
• MRI (magnetic resonance imaging) uses…

  strong magnetic fields and radiowaves to produce detailed images of the body.
• pros of MRI (2)

  -doesn't use ionising radiation

  -Can detect cancer cells, clots and abnormal blood flow
• cons of MRI

  -high cost

  -enclosed space

  -cant tell the difference between malignant and benign
• CT scan (computed tomography scan) uses…

  x rays
• cons of CT scans

  -uses ionising radiation

  -injection of dye
• pros of CT scan

  -can diagnose a number of problems like cancer, strokes, damage to bones and internal organs and can detect size and location of tumour
• EET scanner uses..

  small sensors all over the head to detect electrical signals when the brain’s cells send them to eachother
• EET (electroencepthalography) cons

  cant be used to detect cancer or any disease that doesn’t alter electrical signals
• pros of EET (2(

  used to detect epilepsy fits and memory problems

  no electricity is put into the body so it is very safe
• 5 treatments of brain disorders

  • brain surgery
  • brain implants
  • radiotherapy/chemo
  • monoclonal antibodies
  • stem cell therapies
• brain surgery is used to

  remove as much of a brain tumour as possible
• biggest risk of brain surgery

  brain damage and can cause infection and possibly a stroke
• brain implants involve…

  implanting an electrode into regions of the brain to provide stimulation where it may not receive it
• biggest risk of brain implants

  brain may get damages
• radio/chemo therapy uses

  rays (r) or drugs (c)
• radio/chemo therapy is used for

  removing the tumour and save lives
• brain implants are used for..

  early stages of parkinsons disease
• biggest risk of radio/chemotherapy

  they can both damage healthy cells
• monoclonal antibodies involve

  identifying copies of antibodies that have been made in laboratories
• monoclonal antibodies are used for

  binding to cancer cells and helps the immune system destroy them
• biggest risk of monoclonal antibodies

  skin changes like red/sore/itchy rashes
• stem cell therapies use

  unspecialised cells that can develop into many types of cells
• stem cell therapies are used for

  repairing damages nervous systems and production of cancer-killing molecules
• biggest risk of stem cell therapy

  stem cells can get rejected
