Smoking marijuana in teens may affect verbal abilities

Adolescents who smoke pot as early as 14 have decreased verbal abilities and are more likely to drop out of school than those who hold off until age 17 beforeLIGHTING up their first joint, a new study has found. The study found links between cannabis use and brain impairment only in the areas of verbal IQ and specific cognitive abilities related to frontal parts of the brain, particularly those that require learning by trial-and-error. “We found that adolescents who started using cannabis at 17 or older performed equally well as…

Excessive Marathon Practice Can Adversely Affect Heart

As Mumbai full marathon approaches, doctors have urged participants not to practice excessively as it may have adverse affects on the heart, especially for the adults and senior citizens, said doctors. “People doing regular exercise have a healthy life, but as overdosing of medicines is always toxic, similarly excessive endurance exercise like marathon running, has shown to have paradoxical, adverse effects on the heart,” said Ajay Pandey, Cardiologist at SRV Hospital.

Emotional ‘hangover’ may affect future experiences

Experiencing emotional events — whether happy or painful — may cause ‘hangovers’ that can persist for a long period of time, researchers have found. These ‘hangovers’ could continue after the events have ended and even affect future experiences, the study found. “Emotion is a state of mind. These findings make clear that our cognition is highly influenced by preceding experiences and, specifically, that emotional brain states can persist for long periods of time,” said Lila Davachi, Associate Professor at New York University (NYU). The study also shows that emotional hangover,…

How does sugar in our diet affect our health?

Most adults and children in the UK eat too much sugar. Cut down by eating fewer sugary foods, such as sweets, cakes and biscuits, and drinking fewer sugary drinks.

Poor Sleep May Adversely Affect Kidney Function

Short and poor quality of sleep may worsen kidney function in patients with chronic kidney disease (CKD), says a study. “Short sleep and fragmented sleep are significant yet unappreciated risk factors for CKD progression,” said one of the researchers, Ana Ricardo, from the University of Illinois at Chicago in the US. “Our research adds to the accumulating knowledge regarding the importance of sleep on kidney function, and underscores the need to design and test clinical interventions to improve sleep habits in individuals with CKD,” she added. Although there is increasing…

Mother’s Depression May Affect Kid’s Brain Development

Depressive symptoms in women during and after pregnancy are linked to reduced thickness of the cortex — the outer layer of the brain responsible for complex thought and behaviour — in preschool-age kids, says a new study. “Our findings underscore the importance of monitoring and supporting mental health in mothers not just in the post-partum period, but also during pregnancy,” said lead researcher Catherine Lebel of the University of Calgary in Alberta, Canada. The findings, published in the journal Biological Psychiatry, suggest that a mother’s mood may affect her child’s…
