Intense exercise may help keep Parkinson`s disease at bay Intensive exercise could slow the course of Parkinson's disease, suggests a study, which could pave the way for new non-drug approaches. The study, published in the journal Science Advances, identified a new mechanism responsible for the positive effects of exercise on brain plasticity. It showed that exercise performed in the early stages of the disease induces beneficial effects on movement control that may last over time even after training is suspended, according to Paolo Calabresi...

AI tool detects Alzheimer's with 90% accuracy US researchers have developed a novel Artificial Intelligence-based tool that has shown 90 per cent accuracy in detecting Alzheimer's disease from routinely collected clinical brain images. The tool, developed by a team at Massachusetts General Hospital (MGH), may help clinicians identify patients who would benefit from treatment. The results, published in the journal PLOS ONE, showed that the toll was able to detect Alzheimer's disease regardless of other variables, such as age...

How our body triggers anxiety The brain and the heart can work in tandem to produce anxiety, according to a new mice study. The study, published in the journal Nature, detangles the link whether emotions drive bodily functions or vice versa. It showed that while fear and anxiety can make your heart beat faster, the reverse is also true. To understand, the team increased the heart rate of a mouse. The results showed that speeding up a mouse's heart rate made otherwise calm animals act more anxious. The finding su...

Even low drinking during pregnancy alters baby's brain structure Consumption of alcohol, even in low to moderate amounts during pregnancy, can change the baby's brain structure and delay brain development, a new MRI-based study has warned. Alcohol consumption during pregnancy can expose the fetus to a group of conditions called fetal alcohol spectrum disorders. Babies born with fetal alcohol spectrum disorders could develop learning disabilities, behavioural problems or speech and language delays. "Fetal MRI is a highly specialised and sa...

Are brain diseases surging post Covid? Though Covid-19 infection primarily affects lungs, its effect has been seen on several other organs, particularly the brain. Ahead of the World Brain Day observed annually on July 22, city doctors on Thursday reported a rise in brain diseases like brain strokes and benign brain tumours post pandemic. Covid has significantly impacted the incidence of various brain diseases in India and its full effects are going to be visible in the coming years, said nuero-surgeon Dr. Kamal Verma at Sarvod...

Impact of brain tumour on quality of life A brain tumour develops when certain genes in a cell's chromosomes become faulty and cease to function properly. These genes typically regulate the rate at which the cell divides and repair genes that correct deficiencies in other genes, as well as genes that should cause the cell to self-destruct if the damage is irreparable. A person may be born with a partial defect in one or more of these genes. Environmental factors may then cause additional mutilation. In a few other cases, howev...

How virus infection is linked with progress of brain cancer The cancer-causing virus Epstein Barr Virus (EBV) can infect the neuronal cells and drive various changes in biomolecules such as fatty acids, carbohydrates, and protein components, leading to diseases of the central nervous system as well as brain cancer, scientists have found. The EBV virus has been found to be widely present in the human population. It usually does not cause any harm, but the virus gets reactivated inside the body in some unusual conditions like immunological stress or ...

Explained: How Covid-19 infection damages brain While SARS-CoV-2, the virus causing Covid-19, does not directly affect the brain, the immune response triggered by the infection damages the brain's blood vessels, leading to short- and long-term neurological symptoms, according to a study. In a small study, researchers from the National Institute of Neurological Disorders and Stroke (NINDS), a part of the US National Institutes of Health, examined brain changes in nine people who died suddenly after contracting the virus. They foun...

Reducing air pollution may improve brain development in children Having a portable air cleaner in the home can reduce the negative impacts of air pollution on brain development in children, says a new study. The study, published in the journal Environmental Health Perspectives, found that the children born to mothers who had used the air cleaners had an average full-scale intelligence quotient (FSIQ) that was 2.8-points higher than the group that did not use an air cleaner during pregnancy. "These results, combined with evidence from previous st...

Type 2 diabetes accelerates brain ageing, cognitive decline Scientists have demonstrated that normal brain ageing is accelerated by approximately 26 per cent in people with progressive Type 2 diabetes compared with individuals without the disease, according to a study. There is already strong evidence linking Type 2 diabetes with cognitive decline, yet few patients currently undergo a comprehensive cognitive assessment as part of their clinical care. The results, published today in eLife, suggest that by the time Type 2 diabetes is formally diag...

A pacemaker for brain may treat most severe depression For the first time ever in the world, a woman suffering from a severe form of depression was treated using electric brain implantation, giving hope to millions of people suffering from the mental illness who do not respond to other therapies. Sarah, 38, who asked not to be fully identified, has been implanted with a battery-operated, matchbook-sized device which detects when she is becoming depressed. The experimental therapy led by researchers at the University of California, San Franc...
