The road to alcohol and drug addiction starts with the voluntary decision to take a drink or to take a drug. However, over time, some do not have control over that once-voluntary action. The reason lies within the brain, in parts that affect reward, motivation, learning, memory and behavior. They are critical areas changed because of alcohol and drugs. As Dr. Nora D. Volkow, Director of the National Institute on Drug Abuse (NIDA) explains, addiction is a disease that affects the brain, and thus, behavior.

Dr. Volkow is a pioneer in the use of brain imaging to investigate the toxic and addictive properties of abusive drugs. She recently sat down with Latino Leaders to talk about her work, the addiction problem plaguing the Latino community, what can be done about it, and her role as a leader in the fight.

Her family history, deliciously rich in both medicine and politics, stoked her ambition to study science and have a positive influence on others. Born in Mexico City, Dr. Volkow is the great-granddaughter of Russian revolutionary leader Leon Trotsky. The patriarch immigrated to Mexico because it was the only place that would grant the leader asylum. Dr. Volkow's father, Esteban Volkow, is the son of Leon Trotsky's elder daughter, Zinaida Volkova.

It was an obvious career choice for me, but it was more than that. I am a very inquisitive person. I like to explore things in depth and understand how and why they work. My desire was to marry science with improving the lives of people."

After earning her medical degree from the National University of Mexico in Mexico City, where she received the Robin award for the best medical student of her generation, Dr. Volkow completed her psychiatric residency at New York University (NYU). There, she was presented with the Laughlin Fellowship Award and recognized as one of the 10 outstanding Psychiatric Residents in the United...
