What causes it?
  • There is destruction of brain cells disrupting the transmitters that carry the messages in the brain, particularly those responsible for storing memories.
  • The cause of the destruction remains of the cells unknown.
  • Studies show that genetic factors play part in the development of the disease.
  • The neurotransmitters 'acetylcholine' and 'norepinephrine' are hypothesized to be hypoactive in Alzheimer's disease.
