According to first author Laura Kwako from the National Institute on Alcohol Abuse and Alcoholism in Bethesda, Maryland, although treatment options exist, capitalizing on the burgeoning knowledge of the neurobiological origins of addiction could help find treatments that address the diversity within the addiction diagnosis. The ANA is an effort to meet the need for a neuroscience-based framework for diagnosis which the researchers hope will advance understanding of how addictive disorders emerge and how to classify them.. Past efforts have been made to categorize addictive disorders based on the substance of abuse, for example, alcohol versus cocaine. But differences and similarities between addictions are not constrained by the type of drug. In the review, the researchers propose a dimensional framework, incorporating behavioral measures with brain imaging and genetic data. "It is evident that the current diagnostic categories are broad and encompass enormous clinical heter...

This versatile wearable sensor may be worn on the arm to detect alcohol degree. Credit score: UC San Diego Engineers on the College of California San Diego have developed a versatile wearable sensor that may precisely measure an individual's blood alcohol degree from sweat and transmit the info wirelessly to a laptop computer, smartphone or different cellular gadget. The gadget may be worn on the pores and skin and may very well be utilized by medical doctors and cops for steady, non-invasive and real-time monitoring of blood alcohol content material. The gadget consists of a brief tattoo -- which sticks to the pores and skin, induces sweat and electrochemically detects the alcohol degree -- and a transportable versatile digital circuit board, which is related to the tattoo by a magnet and might talk the knowledge to a cellular gadget by way of Bluetooth. The work, led by nanoengineering professor Joseph Wang and electrical engineering professor Patrick Merci...
