Siblings' brain scans may hold key to addictions By Kate Kelland LONDON | Thu Feb 2, 2012 2:10pm EST (Reuters) - Drug addicts and their non-addicted siblings share certain features in the brain, suggesting a susceptibility to addiction is inherited but is also a flaw that can be overcome, scientists said on Thursday. Researchers who scanned the brains of 50 pairs of brothers and sisters of whom one was a cocaine addict found that both siblings had brain abnormalities that make it more difficult for them to exercise self-control. The findings increase understanding of why some people with a family history of drug abuse have a higher risk of addiction than others and could point to new treatments to help vulnerable people learn how take control before addictions set in. "If we could get a handle on what makes unaffected relatives of addicts so resilient we might be able to prevent a lot of addiction from taking hold," said Paul Keedwell a consultant psychiatrist at Britain's Cardiff University, who was not involved in the research but was encouraged by its findings.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
