Brain function gets better while inhaling: Research

Published

on

JERUSALEM: Israeli research has found that inhalation, for example during a test, improves brain performance, the Weizmann Institute of Science (WIS) in central Israel reported on Wednesday.

The research, published in the journal Nature Human behaviour, found that the success rate of subjects who solved questions during inhalation was higher than their success during exhalation.

The research results may lead to better learning methods, and even help people who suffer from ADHD (Attention Deficit Hyperactivity Disorder) by influencing the nature and pace of their breathing.

The sense of smell is the earliest sense of mammals and is therefore believed to be an initial pattern for all brain development.

The WIS researchers hypothesized that the whole brain is coming to attention of processing information while inhaling, even when it comes to functions that have nothing to do with smell (“sniffing brain”).

First, the researchers measured the flow of air in the noses of subjects while solving math exercises, performing visual-spatial tasks and dealing with language tasks.

The subjects were asked to press a button as soon as they were ready for the next exercise. It turned out that they tended to put air into their bodies in time for their readiness to deal with the next task.

Then, in a visual-spatial task, half of the questions appeared during the subjects’ inhalation and the other half with exhalation. It was found that the success rates were significantly improved when solving questions while inhaling.

The researchers also measured the electrical activity in the subjects’ brains at rest and during taking tasks, and found in both cases that the connectivity between the brain areas was significantly different between inhalation and exhalation.

The researchers noted that the results have nothing to do with oxygen entering the body, as the effect on the brain in the experiments was immediate (about 0.2 seconds).

Sindh health minister appeals to parents not to refuse OPV teams

Published

on

KARACHI: Sindh Minister for Health Dr. Azra Pechuho here on Monday urged parents not to refuse the vaccinators visiting their homes for administration of oral polio vaccine (OPV) even if their children may have been regularly covered under routine immunisation.

Talking to journalists following the inaugural of the national OPV campaign at the Sindh Emergency Operation Centre for Polio, she said the additional drops received by their kids under OPV hold no hazard but simply boost immunity of the recipients.

“The exercise is meant to provide blanket cover to all children against the virus that persists in our environment,” said the health minister who is also a senior doctor.

Acknowledging that a reluctance has been registered among many of the affluent families in easing access of their under-five children to the mobile teams of vaccinators, engaged in door-to-door oral polio immunisation campaign, she said the elitist mindset has to be done away with.

She urged the media, both print and electronic, to make people realise that OPV being administered at the clinics of renowned pediatricians or that of government-run dispensaries or by authorised mobile teams are of same quality arranged by the government through Bill and Melinda Gates Foundation.

Countrywide anti-polio campaign commences

ISLAMABAD: A countrywide campaign to administer anti-polio drops to children under five years of age starts on Monday.

National Coordinator Polio Eradication Programme, Dr Rana Safdar said the anti-polio drive will target 39 million children in all four provinces, Azad Kashmir and Gilgit-Baltistan.

He urged the people to cooperate with polio teams to administer drops to their children against this crippling disease.

FDA approves first medical device to treat child inattention

Published

on

WASHINGTON: The U.S. Food and Drug Administration (FDA) approved this week the first medical device to treat attention deficit hyperactivity disorder (ADHD) for children.

The device called the Monarch external Trigeminal Nerve Stimulation (eTNS) System is the first non-drug treatment for ADHD authorized for marketing by the FDA.

The prescription-only device is indicated for patients ages 7 to 12 years old who are not taking ADHD medication.

“This new device offers a safe, non-drug option for treatment of ADHD in pediatric patients through the use of mild nerve stimulation, a first of its kind,” said Carlos Pena, director of the Division of Neurological and Physical Medicine Devices in the FDA’s Center for Devices and Radiological Health.

ADHD is a common disorder that begins in childhood. ADHD patients have difficulty in staying focused and paying attention.

The cell-phone sized device generates a low-level electrical pulse and connects via a wire to a small patch that adheres to a patient’s forehead, just above the eyebrows, according to FDA.

The device delivers the low-level electrical stimulation to the branches of the trigeminal nerve, sending therapeutic signals to the parts of the brain thought to be involved in ADHD.

Brain imaging showed that eTNS increases activity in the brain regions that are known to be important in regulating attention, emotion and behavior, but the exact mechanism of eTNS is not yet known.

The stimulation feels like a tingling sensation on the skin, and the device should be used in the home under the supervision of a caregiver during periods of sleep. Clinical trials suggest that a response to eTNS may take up to four weeks to become evident.
