Realidades Sobre el SГndrome de Angelman:
InformaciГіn para Familias

En 1965, el Dr. Harry Angelman, un mГ©dico inglГ©s, describiГі por primera vez a tres niГ±os con caracterГsticas, ahora conocidas, como el SГndrome de Angelman (AS)1 . Г‰l notГі que todos tenГan rigidez, andar espГЎstico, ausencia de habla, risa excesiva y crisis convulsivas.Otros casos fueron publicados2,8 de forma esporГЎdica pero la caracterГstica fue considerada sumamente rara y muchos mГ©dicos dudaron de su existencia. Los primeros informes de AmГ©rica del Norte aparecieron a principio de los aГ±os 809-10 y en los diez Гєltimos aГ±os ha aparecido mucha informaciГіn nueva.11,18 El Dr. Angelman relata lo siguiente con respecto a su descubrimiento de este sГndrome(19) ... Sin embargo, estando de vacaciones en Italia, vi una pintura al Гіleo en el museo de Castelvecchio en Verona llamada . . un Muchacho con una muГ±eca. La cara de sonrisa del muchacho y el hecho de que mis pacientes mostraran movimientos rГgidos, me dieron la idea de escribir un artГculo sobre los tres niГ±os con el tГtulo de NiГ±os MuГ±eca ... El sГndrome de Angelman, normalmente, no se detecta en el reciГ©n nacido o en la infancia, dado que los problemas de desarrollo son inespecГficos durante este tiempo. Los padres, en primera instancia, pueden sospechar el diagnГіstico despuГ©s de leer sobre SA o ver a un niГ±o de esas caracterГsticas. La edad mГЎs comГєn de diagnГіstico estГЎ entre tres y siete aГ±os cuando las conductas caracterГsticas y rasgos se hacen mГЎs evidentes. Un resumen del desarrollo y las caracterГsticas fГsicas ha sido recientemente publicado21 con el propГіsito de establecer criterios clГnicos para el diagnГіstico; Г©stos estГЎn pueden verse mГЎs adelante. Todos los rasgos no necesitan estar presentes para que el diagnГіstico pueda ser hecho y el diagnГіstico, a menudo, es lo primero que se sospecha cuando las conductas tГpicas son reconocidas. ...
