La influencia genetica es mas marcada en pacientes con formas graves de trastornos depresivos y sintomas de depresion endogena. El riesgo de morbilidad en parientes en primer grado (padres, hermanos o hijos) esta incrementado en todos los estudios que Se han llevado a cabo, y es independientes de los efectos del ambiente o educacion. marcadores geneticos potenciales para los trastornos talantes han sido localizados en los cromosomas X, 4, 5, 11, 18 y 21.
Se encontro que un polimorfismos funcional en la region promotora del gen del trasportador de la serotonina (5-HHT)modelaba influencia de los eventos estresantes cotidianos en la depresion.

There is a higher genetic influence in patients with severe depressive disorders and endogenous depressive symptoms. The risk of mortality in patients in the first degree (parents, brothers, children) is noticeably increased in many studies, and are independent from factors such as environment and education. Some genetic markers that potentialize the depressive disorders have been found in chromosomes x, 4, 5, 11, 18, and 21.
It has also been found that a functional polymorphism in the premotor region of the transporter gene of serotonin (5-HHT) models influence of every day stressful events in depression.

Drug Addiction/ Adiccion a las Drogas
The next topic on this blog will be about Drug Addiction.
Addiction is a complex disorder characterized by compulsive drug use. People who are addicted feel an overwhelming, uncontrollable need for drugs or alcohol, even in the face of negative consequences. This self-destructive behavior can be hard to understand. Why continue doing something that’s hurting you? Why is it so hard to stop?
The answer lies in the brain. Repeated drug use alters the brain—causing long-lasting changes to the way it looks and functions. These brain changes interfere with your ability to think clearly, exercise good judgment, control your behavior, and feel normal without drugs. These changes are also responsible, in large part, for the drug cravings and compulsion to use that make addiction so powerful.
The path to drug addiction starts with experimentation. You or your loved one may have tried drugs out of curiosity, because friends were doing it, or in an effort to erase another problem. At first, the substance seems to solve the problem or make life better, so you use the drug more and more.
But as the addiction progresses, getting and using the drug becomes more and more important and your ability to stop using is compromised. What begins as a voluntary choice turns into a physical and psychological need. The good news is that drug addiction is treatable. With treatment and support, you can counteract the disruptive effects of addiction and regain control of your life.
La adicción es un trastorno complejo caracterizado por el uso compulsivo de drogas. Las personas que son adictas se tienen un sentimiento abrumador e incontrolable de necesidad por las drogas o el alcohol, aun cuando tienen consecuencias negativas. Este comportamiento auto-destructivo puede ser difícil de entender. ¿Por qué continúan haciendo algo que les daña? ¿Por qué es tan difícil de parar?
