    The Healthy Brain Program, an initiative of the Brain Foundation, aims to assist Australians to keep their brains healthy into old age, through the provision of community education and research. The program aims to address issues such as: People are living longer, and the prevalence of degenerative brain disorders is increasing. There is little information available about how to keep the brain healthy compared to the wealth of information about a healthy body and heart. There is a need for a coordinated approach to education on key indicators and risk reduction strategies.

Does Vitamin D Improve Brain Function?: Scientific American - 0 views

vitamin D improve brain function

  • And although vitamin D is well known for promoting bone health and regulating vital calcium levels—hence its addition to milk—it does more than that. Scientists have now linked this fat-soluble nutrient’s hormonelike activity to a number of functions throughout the body, including the workings of the brain.
  • We know there are receptors for vitamin D throughout the central nervous system and in the hippocampus
  • We also know vitamin D activates and deactivates enzymes in the brain and the cerebrospinal fluid that are involved in neurotransmitter synthesis and nerve growth.
  • ...5 more annotations...
  • In addition, animal and laboratory studies suggest vitamin D protects neurons and reduces inflammation.
  • The scientists found that the lower the subjects’ vitamin D levels, the more negatively impacted was their perform­ance on a battery of mental tests. Compared with people with optimum vitamin D levels, those in the lowest quartile were more than twice as likely to be cognitively impaired.
  • The data show that those people with lower vitamin D levels exhibited slower information-processing speed. This correlation was particularly strong among men older than 60 years.
  • Although we now know that low levels of vitamin D are associated with cognitive impairment, we do not know if high or optimum levels will lessen cognitive losses. It is also unclear if giving vitamin D to those who lack it will help them regain some of these high-level functions.
  • So how much is enough vitamin D? Experts say 1,000 to 2,000 IU daily—about the amount your body will synthesize from 15 to 30 minutes of sun exposure two to three times a week—is the ideal range for almost all healthy adults. Keep in mind, however, that skin color, where you live and how much skin you have exposed all affect how much vitamin D you can produce.

    The UCF team found that over time, though there are no outward signs of damage, exposure to moderate amyloid-beta concentrations somehow prevents electrical signals from traveling normally through the cells. Because the effect is seen in otherwise healthy cells, Hickman believes the team may have uncovered a critical process in the progression of Alzheimer's that could occur before a person shows any known signs of brain impairment.
