Smartphones are injurious for child’s mental health

Smartphones, an essential part of human in daily life but as experts say that excessive use of anything is always harmful and same goes to the gadget that revolutionised the 21st century.  In a new find, researchers have revealed that excessive use of smartphones can hamper the mental ability. What’s striking is that teenagers are at higher risk of smartphone-aided mental sickness.

Approximately 46 percent people admit the fact that they can not live without their smartphones, stated in a study. Even the researchers examined the minds of smartphones and internet-addicted teenagers with the help of magnetic resonance spectroscopy (MRS) and analysed the insights of their brains. Meanwhile, MRS is a type of MRI which maps the brain’s chemical balance.

The researchers examined 19 teenage people with the mean age of 15.5 and 9 people were male. All these people were diagnosed with the internet or smartphone addiction. In this figure, 12 teens were treated with the cognitive behavioural therapy for 9 weeks. The therapy was basically modified as originally meant for treatment of gaming addiction. The researcher  suggested that high score leads to more critical addiction. The smartphone or internet-addicted teenagers showed higher scores in the symptoms anxiety, impulsivity, insomnia severity, and depression, as per the results of research.

The researchers conducted MRS exam on the teenagers who were getting treated with behavioural therapy and an individual MRS study on the patients to estimate the levels of GABA(gamma-aminobutyric acid). While GABA is a neurotransmitter in the brain which restrains or slows down brain signals, and glutamate-glutamine (Glx), a neurotransmitter that causes neurons to become more electrically stimulated.

In the anterior cingulate cortex of smartphone-addicted youth before having therapy, the ratio of GABA to Glx was notably enhanced, mentioned in research results. Meanwhile, the increased presence of GABA can result in the number of side effects such as anxiety and drowsiness.

The researcher further stated that the elevated GABA levels and disrupted the balance between GABA and glutamate in the anterior cingulate cortex may contribute to our understanding the pathophysiology of and therapy or medications for addictions.

So, it is well said, ‘Prevention is better than cure,’ as it is not necessary to get addicted first and then use the therapies for curing the addiction. If you are a parent then pay attention to your kids and if you are a teenager then you are mature enough to understand the side effects of excessive use of everything.

Being overweight can negatively affect memory, emotions and appetite

A new study has found that being overweight appears to be related to reduced levels of a molecule that reflects brain cell health in the hippocampus, a part of the brain involved in memory, learning, and emotions, and likely also involved in appetite control.

Jeremy D. Coplan, MD, professor of psychiatry at SUNY Downstate Medical Center, led a multicenter team that visualized the molecule, N-acetyl-aspartate (NAA), using magnetic resonance spectroscopy, a non-invasive magnetic resonance imaging (MRI) application.

NAA is associated with brain cell health. Overweight study participants exhibited lower levels of NAA in the hippocampus than normal weight subjects. The effect was independent of age, sex, and psychiatric diagnoses.

The importance of the hippocampus – a seahorse-shaped organ deep within the brain – to the formation and preservation of memory and to emotional control is well known, Dr. Coplan said, but its role in appetite control is less established.

"The relevance of the finding is that being overweight is associated with specific changes in a part of the brain that is crucial to memory formation and emotions, and probably to appetite," Dr. Coplan said.

The study is believed to be the first human research documenting the association of NAA with body weight.

"Whether low NAA is a consequence of being overweight, causes being overweight, or a combination of both remains to be determined," he added.
