Insulin

• Insulin, which is normally used to regulate blood sugar, may play a part in increasing memory function in Alzheimer's patients.
  
  

Administering Insulin

• Administering insulin to the brain without affecting blood sugar has been a problem that has potentially been solved by delivering it through a nasal spray.
  
  

Patent

• The nose-to-brain method of administering drugs was invented and patented in the 1980s by William Frey II, who was the director of an Alzheimer's research center.
  
  

Research

• Several studies have been conducted concerning nasal spray treatment and have shown positive results, especially when administered to patients in the early stages of Alzheimer's.
  
  

Additional Research Needed

• More research is planned, and considered necessary by many medical professionals, to further test the safety and effectiveness of intranasal insulin therapy for the treatment of Alzheimer's patients.
