Thousand genes differences contribute to autism risk

Changes in scores of genes contribute to autism risk — Newfound genetic differences provide many hints at causes – Small differences in as many as a thousand genes contribute to risk for autism or autism spectrum disorder (ASD). This new study examined data on several types of rare, genetic differences in more than 14,000 DNA samples from parents, affected children, and unrelated individuals.

Autism linked to maternal exposure to agricultural pesticides

Autism – Study finds association between maternal exposure to agricultural pesticides – Pregnant women who lived in close proximity to fields and farms where chemical pesticides were applied experienced a two-thirds increased risk of having a child with autism spectrum disorder or other developmental delay.

Alzheimer’s related memory loss linked to Neuroligin-1 protein

Cleveland Clinic identifies mechanism in Alzheimer’s-related memory loss — Study uncovers role of Neuroligin-1 protein – Cleveland Clinic researchers have identified a protein in the brain that plays a critical role in the memory loss seen in Alzheimer’s patients. The protein – Neuroligin-1 (NLGN1) – is known to be involved in memory formation; this is the first time it’s been linked to amyloid-associated memory loss.

High good and low bad cholesterol levels healthy for brain

High good and low bad cholesterol levels are healthy for the brain, too – High levels of “good” cholesterol and low levels of “bad” cholesterol are correlated with lower levels of the amyloid plaque deposition in the brain that is a hallmark of Alzheimer’s disease, UC Davis researchers have found.

Vitamin E may slow functional decline in Alzheimer’s Disease patients

Vitamin E May Delay Decline in Mild-to-Moderate Alzheimer’s Disease — Study Shows Benefit in Activities of Daily Living and Savings in Caregiver Time with Vitamin E – A new research suggests that alpha tocepherol, fat-soluble Vitamin E and antioxidant, may slow functional decline (problems with daily activities such as shopping, preparing meals, planning, and traveling) in patients with mild-to-moderate Alzheimer’s disease and decrease caregiver burden.

Concussions may be related to Alzheimer’s disease

Are concussions related to Alzheimer’s disease? – A history of concussion involving at least a momentary loss of consciousness may be related to the buildup of Alzheimer’s-associated plaques in the brain, revealed by researchers in Neurology, the medical journal of the American Academy of Neurology.

ADHD linked to social and economic status

ADHD linked to social and economic disadvantage — Scientists have found evidence of a link between social and economic status and childhood attention deficit disorder in the UK – Scientists have found evidence of a link between social and economic status and childhood attention deficit disorder (ADHD) in the UK. A team led by the University of Exeter Medical School analysed data from the Millennium Cohort Study, a database of more than 19,500 UK children born between 2000 and 2002.

Copper triggers and enhances progression of Alzheimer’s disease

Copper identified as culprit in Alzheimer’s disease – Copper appears to be one of the main environmental factors that trigger the onset and enhance the progression of Alzheimer’s disease by preventing the clearance and accelerating the accumulation of toxic proteins in the brain.

Induced or augmented childbirth increases autism risk in childhood

Induced or augmented childbirth appears to be associated with increased risk for autism – An analysis of North Carolina birth and educational records suggests that induction (stimulating uterine contractions prior to the onset of spontaneous labor) and augmentation (increasing the strength, duration, or frequency of uterine contractions with spontaneous onset of labor) during childbirth appears to be associated with increased odds of autism diagnosis in childhood.
