Diabetes Can Double Alzheimer’s Risk

September 22, 2011

A new study conducted in Japan is claiming that diabetes can dramatically increase a person’s risk of developing Alzheimer’s disease later in life.

The study included more than 1,000 men and women over age 60, and researchers found that people with diabetes were twice as likely as the other study participants to develop Alzheimer’s disease within 15 years. They were also 1.75 times more likely to develop dementia of any kind.

Researchers stress that further study is still needed to determine why diabetes increases the risk of Alzheimer’s, but most agree that, for whatever reason, the link does exist.

Some possible theories for why the link exists include:

  • Insulin resistance may interfere with the body’s ability to break down the protein amyloid that forms brain plaques linked to Alzheimer’s.
  • High blood sugar produces certain oxygen-containing molecules that can damage cells, in a process known as oxidative stress. Additionally, high blood sugar plays a role in the hardening and narrowing of arteries in the brain which can kill brain tissue.
The link between diabetes and dementia risk persisted even after the researchers took into account several factors associated with both diabetes and dementia risk, such as age, sex, blood pressure, and body mass index.

Typical Teenage Behavior or Sleep Disorder?

Now that school is back in session, are you struggling to drag your teenager out of bed? Check out an excerpt from Dr. Rosenberg’s latest contribution to the Huffington Post below. Then read the full article to learn more about Delayed Sleep Phase Disorder.

Several years ago a mother, father and their 17-year-old son came to our sleep clinic to discuss the son’s “sleeping problem.” A senior in high school, the teenager had missed about 50 percent of his first period classes and was in danger of failing. According to his mother, the problem was simple: “He cannot get up in time for school.”

His father was less concerned. Dad believed the problem was also simple — his son was a “slacker” and just needed to go to bed on time. Weeks before their appointment, the son’s sleep problems had resulted in a somewhat tumultuous home situation with the police having to break up a family disturbance.
