Frequent cannabis use by young people linked to decline in IQ
A study has found that adolescents who frequently use cannabis may experience a decline in Intelligence Quotient (IQ) over time. The findings of the research provide further insight into the harmful neurological and cognitive effects of frequent cannabis use on young people.
The paper, led by researchers at RCSI University of Medicine and Health Sciences, is published in Psychological Medicine.
The results revealed that there were declines of approximately 2 IQ points over time in those who use cannabis frequently compared to those who didn’t use cannabis. Further analysis suggested that this decline in IQ points was primarily related to reduction in verbal IQ.
The research involved systematic review and statistical analysis on seven longitudinal studies involving 808 young people who used cannabis at least weekly for a minimum of 6 months and 5308 young people who did not use cannabis. In order to be included in the analysis each study had to have a baseline IQ score prior to starting cannabis use and another IQ score at follow-up. The young people were followed up until age 18 on average although one study followed the young people until age 38.
“Previous research tells us that young people who use cannabis frequently have worse outcomes in life than their peers and are at increased risk for serious mental illnesses like schizophrenia. Loss of IQ points early in life could have significant effects on performance in school and college and later employment prospects,” commented senior author on the paper Professor Mary Cannon, Professor of Psychiatric Epidemiology and Youth Mental Health, RCSI.
“Cannabis use during youth is of great concern as the developing brain may be particularly susceptible to harm during this period. The findings of this study help us to further understand this important public health issue,” said Dr Emmet Power, Clinical Research Fellow at RCSI and first author on the study.
The study was carried out by researchers from the Department of Psychiatry, RCSI and Beaumont Hospital, Dublin (Prof Mary Cannon, Dr Emmet Power, Sophie Sabherwal, Dr Colm Healy, Dr Aisling O’Neill and Professor David Cotter).
The research was funded by a YouLead Collaborative Doctoral Award from the Health Research Board (Ireland) and a European Research Council Consolidator Award.

Investir em educação para a primeira infância é melhor ‘estratégia anticrime’, diz Nobel de Economia
James Heckman já era vencedor do Nobel de Economia quando começou a se dedicar ao assunto pelo qual passaria a ser realmente conhecido: a primeira infância (de 0 a 5 anos de idade), sua relação com a desigualdade social e o potencial que há nessa fase da vida para mudanças que possam tirar pessoas da pobreza.

O glioblastoma é o tipo de tumor primário mais comum no cérebro, altamente agressivo e maligno. Pacientes com esse tipo de câncer geralmente são submetidos a ressecção seguida de radioterapia e quimioterapia. Apesar do tratamento, a sobrevida é de 12 a 18 meses a partir da data do diagnóstico. Novos tratamentos têm sido desenvolvidos e um deles tem se mostrado promissor. O estudo da referência aborda uma técnica que envolve a aplicação de ultrassom focal na região tumoral através do crânio intacto associada à aplicação de uma substância que sensibiliza as células para os efeitos prejudiciais do som. A terapia sonodinâmica representa uma grande promessa para o tratamento de cânceres que se espalharam para áreas sensíveis do corpo (metástases) e, em particular, do cérebro. 📑♒🧠Este tema será abordado no módulo Tratamento & Reabilitação do Cérebro da @mybrainuniversity

The human brain builds structures in 11 dimensions, discover scientists
The brain continues to surprise us with its magnificent complexity. Groundbreaking research that combines neuroscience with math tells us that our brain creates neural structures with up to 11 dimensions when it processes information. By “dimensions,” they mean abstract mathematical spaces, not other physical realms. Still, the researchers “found a world that we had never imagined,” said Henry Markram, director of the Blue Brain Project, which made the discovery.
YOUR BRAIN IS NOT FULLY DEVELOPED UNTIL AGE TWENTY-FIVE
We may like to assume that we are adults when we turn eighteen; however, the truth is our brain is still undergoing a significant amount of construction until our mid-twenties. Research has shown that the brain is not fully developed until a person reaches about the age of twenty-five. For males, full development can extend until the age of twenty-eight. What does this mean for you? If you are under twenty-five, this means every decision you make, every thought you have, every action you take, all the food you eat, the amount of sleep you get and everything else you do throughout your day has significant impact on your developing brain.

Estoy segura que todos conocemos a una persona que siempre está con una actitud negativa. Esa persona que pensamos que siempre ve el vaso vacío a la mitad, pero que insiste en ser un realista. En mi caso, esa persona es una amiga desde la infancia, Sam.
