A medida que crec\u00edan, sus niveles de dopamina cerebral aumentaban de forma constante pero r\u00e1pida, coincidiendo con la disminuci\u00f3n de su consumo de sustancias.<\/p>\n<p>\u00abLa cuesti\u00f3n clave no es qui\u00e9n experimenta, sino qui\u00e9n contin\u00faa y qui\u00e9n escala su uso hasta la edad adulta\u00bb, dijo Parr. \u00abAl rastrear a los adolescentes a lo largo del tiempo, pudimos identificar marcadores cerebrales y conductuales tempranos que ayudan a distinguir experimentos temporales y t\u00edpicos del desarrollo de patrones que pueden se\u00f1alar un mayor riesgo a largo plazo.\u00bb<\/p>\n<p>La investigadora principal Beatriz Luna, profesora de psiquiatr\u00eda en la Universidad de Pittsburgh, afirm\u00f3 que asumir riesgos es una parte normal de la adolescencia.<\/p>\n<p>\u00abPara la mayor\u00eda de los ni\u00f1os es una fase que alcanza su punto \u00e1lgido y luego se relaja\u00bb, dijo en un comunicado de prensa.<\/p>\n<p>\u00abLos padres pueden ayudar dirigiendo ese impulso por nuevas experiencias gratificantes hacia salidas sociales positivas como los deportes de equipo, para que los adolescentes puedan perseguir esa &#8216;recompensa&#8217; en lugares m\u00e1s saludables\u00bb, dijo Luna.<\/p>\n<p>M\u00e1s informaci\u00f3n<\/p>\n<p>La Cleveland Clinic tiene m\u00e1s informaci\u00f3n sobre la dopamina.<\/p>\n<p>FUENTES: Nota de prensa de la Universidad de Pittsburgh, 11 de junio de 2026; Nature Communications, 11 de junio de 2026<\/p>\n","protected":false},"excerpt":{"rendered":"<p>VIERNES, 12 de junio de 2026 (HealthDay News) &#8212; Probando marihuana, alcohol o fumar.
