Un equipo de investigadores de Escocia evaluó la capacidad mental de 465 personas que habían participado en un test de inteligencia a los 11 años, en 1947.
Los voluntarios fueron sometidos a una nueva prueba entre 2000 y 2002, cuando tenían 64 años de edad. Aproximadamente 50% eran fumadores. "Los fumadores tuvieron resultados mucho peores en cinco tests diferentes de conocimientos que los ex fumadores y los que nunca habían fumado", indicaron los autores de este estudio.
"Cuando factores sociales y sanitarios como la educación, la ocupación y el consumo de alcohol se tomaban en cuenta, fumar surgía como un elemento que provocaba una caída en la capacidad cognitiva de hasta 1%", afirma dicho estudio.
