DDT exposure causes sodium channels to remain open, leading to increased neural firing and an increased release of amyloid beta peptide. Blocking the channels with tetrodotoxin reduces the toxic amyloid protein by increasing the production of the amyloid precursor protein.
Researchers found a close association between high aluminum content in brain tissue and amyloid-beta location in post-mortem samples of people with familial Alzheimer's disease. The findings back up previous claims that aluminum exposure may be linked to the development of the neurodegenerative disease.
A new study reports the in utero environment can impact teenage brain development, contributing to problems with cognitive processing and emotional regulation.
According to a new study, synthetic chemicals found in some insecticides can bind to melatonin receptors, creating a higher risk for people to develop diabetes and other metabolic disorders.
Poor air quality has been linked to higher rates of bipolar disorder and major depressive disorder. Exposure to air pollution during the first ten years of like is also associated with a more than two-fold increased risk of schizophrenia and personality disorders.
The effects of lead exposure on overall health have been well document, but a new study reveals early exposure to pollution can have a detrimental effect on personality. Researchers report those who were born following the decline of environmental lead levels had more mature personalities and were more conscientious and less had lower levels of neuroticism than those born in generation with higher lead levels.
A new study looks at the long term ramifications of childhood lead exposure, finding links to lower cognitive function, IQ and socioeconomic status.
Early-life exposure to car exhaust from leaded gas reduced the IQ of around 170 million Americans, a new study reports.
Researchers report higher levels of urinary fluoride during pregnancy is associated with a higher risk of ADHD in school aged children. The study reports prenatal fluoride exposure is most strongly associated with inattentive behavior and cognitive problems in the children.
The living environment has a significant impact on the skin microbiota, but not gut bacteria, in both humans and dogs.
Living less than 50 meters away from a major road, or less than 150 meters away from a highway, increases the risks for dementia, Alzheimer's disease, Parkinson's disease, and multiple sclerosis. However, living close to green spaces appears to have more of a protective effect against neurodegenerative diseases.
