Alzheimer’s disease is a progressive neurologic disorder that causes the brain to shrink (atrophy) and brain cells to die which is the most common cause of dementia a continuous decline in thinking, behavioral and social skills that affects a person’s ability to function independently.



  • Unknown but involves amyloid beta accumulation initially, then synaptic dysfunction, neuro-degeneration, and eventual neuronal loss
  • Age, genetics, systemic disease, behaviors (smoking), and other host factors may influence the response to amyloid beta and/or the pace of progression toward the clinical manifestations of AD.



  • Aging, family history, Down syndrome
  • Hypertension, cardiovascular, and carotid artery disease
  • Smoking
  • Head trauma



  • Intellectual challenge (puzzles) and regular physical exercise may offer preventive benefit.
  • You have to control your vascular risk factors (e.g., hypertension) and you have to monitor your cholesterol as well.
  • Physical activities may help to prevent or delay cognitive decline.
  • Ginkgo biloba extracts (120 mg/day) is beneficial especially if your condition is associated with memory loss and loss of cognition.
  • Coenzyme Q10.
  • Omega-3 fatty acids.


  • You need to optimize treatment of associated associated conditions (including hearing and vision loss).
  • You have to monitor your environment for safety and security and avoid sudden changes in environment.
  • High-fat (70%) diet found to be as effective in slowing progression as medications in small trials.

  • Galantamine: Start at 4 mg BID for 4 weeks, then increase by 4 mg BID every month with goal of 16 to 24 mg/day dose.
  • N-methyl-d-aspartate (NMDA) receptor antagonists.
