Numerous studies have documented the normal age-related decline of neural structure, function, and cognitive performance. Preliminary evidence suggests that meditation may reduce decline in specific cognitive domains and in brain structure. Here we extended this research by investigating the relation between age and fluid intelligence and resting state brain functional network architecture using graph theory, in middle-aged yoga and meditation practitioners, and matched controls. Fluid intelligence declined slower in yoga practitioners and meditators combined than in controls.

Neurodevelopmental disabilities, including autism, attention-deficit hyperactivity disorder, dyslexia, and other cognitive impairments, affect millions of children worldwide, and some diagnoses seem to be increasing in frequency. Industrial chemicals that injure the developing brain are among the known causes for this rise in prevalence. In 2006, we did a systematic review and identified five industrial chemicals as developmental neurotoxicants: lead, methylmercury, polychlorinated biphenyls, arsenic, and toluene.

Very high levels of prenatal maternal mercury have adverse effects on the developing fetal brain. It has been suggested that all possible sources of mercury should be avoided. However, although seafood is a known source of mercury, little is known about other dietary components that contribute to the overall levels of blood mercury. The objective of the study was to quantify the contribution of components of maternal diet to prenatal blood mercury level.

Changes in electroencephalography (EEG) amplitude modulations have recently been linked with early-stage Alzheimer’s disease (AD). Existing tools available to perform such analysis (e.g., detrended fluctuation analysis), however, provide limited gains in discriminability power over traditional spectral based EEG analysis. In this paper, we explore the use of an innovative EEG amplitude modulation analysis technique based on spectro-temporal signal processing.

Order of the Karnataka High Court on assailing the notification dated 18.06.2013 bearing No.G.S.R.377(E) issued by the Ministry of Health and Family Welfare and to quash the recommendations of New Drugs Advisory Committee (Neurology & Psychiatry) (‘NDAC’ for short) at Sl.No.7(10) pursuant to the meeting held on 11.05.2013.

There is increasing concern about the potential effects of traffic-related air pollution (TRAP) on the developing brain. The impact of TRAP exposure on childhood behavior is not fully understood due to limited epidemiologic studies. The objective of the study was to explore the association between early life exposure to TRAP using the surrogate, elemental carbon attributed to traffic (ECAT), and attention deficit/hyperactivity disorder (ADHD) symptoms at age seven.

Curcumin is a component of turmeric, a spice used in many types of cooking. Epidemiological evidence suggesting that populations that eat food with a substantial amount of curcumin were at lower risk of Alzheimer’s disease (AD) led to the idea that this compound might have a neuroprotective effect. Curcumin has substantial antioxidant and anti-inflammatory effects, and is being used as a potential preventative agent or treatment for many types of cancer.

New Delhi: Your fear about excessive use of mobile phones causing serious health problems was not ill-founded after all. Months after World Health Organization classified radiofrequency electromagnetic field (EMF) as ‘possibly carcinogenic to humans’, another global report has redflagged the use of such technology, citing health risks, including growth of brain tumour and loss of fertility in men.

BioInitiative 2012 — which is a collaborative effort by 29 authors from 10 countries, including the chair of the Russian national committee on non-ionizing radiation, a senior adviser to the European Environmental Agency and two professors from Jawaharlal Nehru University, Delhi — calls for a review of public safety limits.

Prolonged exposure to radiation from cellphone towers, other wireless technologies can cause imbalance in immune system, metabolism, reproductive system warns this report by the BioInitiative Working Group 2012 based on 1,800 new scientific studies.

Cadmium is a commonly occurring toxic food contaminant, but health consequences of early-life exposure are poorly understood.
 The researchers evaluated the associations between cadmium exposure and neurobehavioral development in preschool children.
