The Larger Head Size Reduces Brain Atrophy In Alzheimer’s Disease – Part 2 of 3

Nevertheless, there could be a connection between the size of the brains and how many neurons are available to “pick up the slack” when others go dark because of diseases such as Alzheimer’s. The new study, published in the July 13 issue of Neurology, explores that possibility.

The study authors examined the medical records of 270 patients with Alzheimer’s. They looked for links between sense shrinkage, head circumference – an indicator of brain size – and the progression of their disease.

After adjusting their results so they wouldn’t be thrown off by factors such as the ripen and ethnicity of the patients, the researchers found that patients with larger head sizes tended toward less brain atrophy. Also, their dementia was less advanced. While the balance between larger-headed and smaller-headed people was significant from a statistical point of view, study co-author Farrer said it’s impossible to pinpoint exactly what the difference means in terms of how the brain works overall.
