Therefore, initial warning signs can often be missed, or even ignored due to conventional wisdom that suggests it's better to wait for true behavioral deterioration and prolonged patterns of abnormality before diagnosing and treating a mental illness. But experts warn that waiting until someone is so ill that the psychological sickness is unmistakable can be detrimental and can lead to long-term health concerns. In an effort to end the waiting game, Northwestern Medicine behavioral health experts from the Stone Institute of Psychiatry at Northwestern Memorial Hospital and Northwestern University Feinberg School of Medicine have launched First Contact, a program aimed at preventing the onset of long-term disability due to severe mental illness by increasing awareness of signs and symptoms and encouraging people to seek help earlier. http://medicalxpress.com/news/2012-04-contact-early-intervention-key-diagnosis.html Psychology & Psychiatry Mon, 16 Apr 2012 13:53:10 EST news253803160 As they work together to form body parts, cells in developing organisms communicate like workers at a construction site. The discovery of a new signaling molecule in flies by Brown University biologists not only helps explain how cells send many long-haul messages, but also provides new clues for researchers who study how human development goes awry, for instance in cases of cleft lip and palate. http://medicalxpress.com/news/2012-04-newly-protein-cells-tissues.html Medical research Mon, 02 Apr 2012 11:03:20 EST news252583391 A second mutation found in the tumors of patients with BRAF-mutated metastatic melanoma does not contribute to resistance to BRAF inhibitor drugs, a finding that runs counter to what scientists expected to be true. http://medicalxpress.com/news/2012-04-mutation-braf-mutated-melanoma-doesnt-contribute.html Cancer Sun, 01 Apr 2012 14:39:18 EST news252509939 Conventional wisdom tells us that in the business world, "you are who you know" — your social background and professional networks outweigh talent when it comes to career success.
