e tiology

Biological perspective

  • Neurofibrillary tangles, the cellular material within the cell bodies of neurons becomes replace by densely packed, twisted micro fibrils or tiny strands of proteins.
  • Amyloid plaques, clusters of dead dying neurons mixed with fragments of protein molecules.

Environmental perspective

  • the American diet or culture have increased the risk of the Japanese American men.
  • Alzheimer’s disease is most commonly found on people from the age 60 yrs & older.
  • It is estimated that as many as 5.1 million Americans may have Alzheimer's disease.
  • There is no cure for this disease but medication can control it
  • Memory loss, loss of verbal abilities, requires assistance in feeding and forgets how to walk
  • no chance of improvement because as time passes by the persons ability use cognitive thinking worsens
