Sin embargo, muchos atletas j\u00f3venes muestran s\u00edntomas antes de que aparezca esta prote\u00edna, lo que ha llevado a investigadores liderados por Jonathan Cherry, de la Escuela de Medicina de la Universidad de Boston (EE UU), a indagar en las primeras alteraciones cerebrales.<\/p>\n<p><a><\/a><\/p>\n<h2>An\u00e1lisis de tejido cerebral<\/h2>\n<p>El equipo analiz\u00f3 tejido cerebral de 28 personas menores de 51 a\u00f1os: ocho sin antecedentes de traumatismo, nueve deportistas sin rastro de tau y once atletas con CTE incipiente.
