MENTAL HEALTH AND EXERCISE
Dr. Gupta's mailbag; What's bad for the heart is bad for the brain and *physical activity can actually repair neurological connections in your brain* - CNN
- What's bad for the heart is bad for the brain, the brain requires a lot of blood flow.
- Mini strokes happen all the time in the brain without much damage but over time can lead to problems associated to Alzheimer's.

Exercise early in life gives the brain a boost, women 35% less likely to be mentally impaired - CNN
- older women who exercised in their teens are 35% less likely to be mentally impaired at old age.
- exercise early in life given the brain a boost as it develops.
- repairs brain cells called neurons and that tends to stay through old age.
Fitness helps the brain
Researchers found that the physically fit children tended to have bigger hippocampal volume, about 12% bigger - EurekaAlert! (article link)
"In animal studies, exercise has been shown to specifically affect the hippocampus, significantly increasing the growth of new neurons and cell survival, enhancing memory and learning, and increasing molecules that are involved in the plasticity of the brain,"
- Those who are more fit tend to have a bigger hippocampus and perform better on a test of memory than their less-fit peers.
- The researchers found that the physically fit children tended to have bigger hippocampal volume – about 12% bigger relative to total brain size – than their out-of-shape peers.
- A bigger hippocampus is associated with better performance on spatial reasoning and other cognitive tasks.
- "This is the first study I know of that has used MRI measures to look at differences in brain between kids who are fit and kids who aren't fit," -- "Beyond that, it relates those measures of brain structure to cognition."
Children's brain development is linked to physical fitness
"Exercise is as close to a magic bullet as brain fitness gets," John Medina, PhD, Brain Center for Applied Learning - Prevention
"Exercise is as close to a magic bullet as brain fitness gets," says John Medina, PhD, director of the Brain Center for Applied Learning at Seattle Pacific University. Physical activity bathes neural tissue in oxygen-rich blood, increasing the production of chemicals that improve memory, attention, and problem-solving.
- When sedentary adults in one study jogged for half an hour 2 or 3 times a week for 12 weeks, their memory and ability to juggle tasks improved by 30%.
- A study in the American Journal of Public Health reported that women with large social networks slashed their risk of dementia by as much as 26%.

Vitamin B could help prevent Alzheimer's
Vitamin B can halve the rate of brain shrinkage and slow progression towards dementia - Reuters (article link)
"mild cognitive impairment" -- a major risk factor for Alzheimer's disease and other forms of dementia -- affects around 16% of people aged over 70 worldwide and is characterized by slight problems with memory loss, language or other mental functions. -- around 50% of people diagnosed with it go on to develop Alzheimer's disease within five years.
- Volunteers were given either a vitamin pill containing very high doses of folic acid, vitamin B6 and vitamin B12, or a placebo dummy pill.
- The pills contained around 300 times the recommended daily intake of B12, 4 times daily advised folate levels and 15 times the recommended amount of B6.
On average the brains of those taking the vitamin treatment shrank at a rate of 0.76% a year, while those taking the dummy pill had an average brain shrinkage of 1.08%.

Vitamin D may help prevent dementia and cognitive decline by having a role in nervous tissue formation and maintaining calcium in the body - Reuters (article link)
- People severely vitamin D deficient were 60% more likely to experience substantial general cognitive decline, 31% more likely to experience cognitive problems.
- Dementia, such as Alzheimer's, is a brain-wasting condition that affects around 35 million people worldwide -- Vitamin D may help prevent the degeneration of brain tissue by having a role in formation of nervous tissue,
maintaining levels of calcium in the body, or clearing of beta-amyloid, the substance that forms the brain plaques that are associated with Alzheimer's disease.
Low vitamin D increases risk of dementia in elderly
(Reuters) - Older people with low levels of vitamin D appear more likely to have problems with memory, learning and thinking, suggesting low vitamin D could give an early warning for dementia risk, scientists said on Monday.

Canada tracks BPA exposure, studies suggest BPA exposure early in life can affect neural development and behavior - Reuters (article link)
Studies suggesting that low exposure levels early in life can affect neural development and behavior prompted Canada to announce plans to ban its use in baby bottles. Some consumer groups, citing research linking it to cancer, obesity, diabetes and heart disease, want restrictions to be wider than that.
- Statscan report found a mean concentration of 1.16 micrograms per liter in the urine of Canadians tested.
- Teenagers had the highest concentrations of BPA, while children between 6 and 11 had higher concentrations then adults over 40.
- "Cash register receipts are slathered in this stuff...and you absorb it through your skin," advocacy group Environmental Defense.
BPA is used in plastic bottles and as a coating for everything from shopping receipts to a lining for cans of foods, but it also has many other uses.

Pesticides, organophosphates attack nervous systems of bugs and neurotransmitters, linked to ADHD in Children and Parkinson's - Reuters
Women with more chemical traces of the pesticides in their urine while pregnant had children more likely to have symptoms of ADHD -- a tenfold increase in pesticide metabolites in the mother's urine correlated to a 500% increase in the chances of ADHD symptoms by age 5.
- A different team found children with high levels of organophosphate traces in the urine were almost twice as likely to develop ADHD.
- Studies have also linked exposure to Parkinson's, an incurable brain disease.
Organophosphates are designed to attack the nervous systems of bugs by affecting message-carrying chemicals called neurotransmitters including acetylcholine, which is important to human brain development.

Nonstick coating chemical PFOA linked to higher cholesterol LDL in children and perfluoroalkyl acids are a known neurotoxin - Reuters
Children with the highest PFOA concentration had total cholesterol levels that were 4.6 points higher and LDL levels that were 3.8 points higher than those with the lowest PFOA levels.
- The researchers studied perfluorooctanoic acid or PFOA and perfluorooctanesulfonate or PFOS.
- Studies in animals suggest perfluoroalkyl acid can affect the liver, which could result in changes in cholesterol levels.
- They make their way into people through drinking water, dust, food packaging, breast milk, cord blood, microwave popcorn, air and occupational exposure.
Bernard Weiss of the University of Rochester in New York, an expert on toxins said perfluoroalkyl acids are a known neurotoxin. -- "They interfere with brain development, which leaves its mark on later behavioral functions such as cognitive performance,"
