Six patients with primary degenerative dementias and frontal or frontotemporal hipoperfusion are reported. Five were diagnosed as Frontal Progressive Dementia (FPD), characterized by striking changes in personality and social behavior. The last patient had a progressive aphasia and a moderate cognitive impairment. We discuss the heterogeneity of FPD that includes Pick's disease, frontal lobe type dementia (Neary) and progressive subcortical gliosis. The usefulness of Spect and the need of a brain bank are remarked

El aprendizaje procedural y episódico es estudiado en un paciente masculino de 41 años, portador de un síndrome de Korsakoff crónico post-traumático y cuya tomografía computarizada mostró dilatación bilateral de los cuernos frontales y agrandamiento ventricular. Se realizaron 10 sesiones diarias, entrenando la lectura de logotomas y párrafos invertidos. Hubo una significativa disminución del número de errores en el tiempo de lectura, a pesar de no recordar los entrenamientos previos. Esto confirma la disociación entre el episodio olvidado y la preservación de la memoria procedural, disociación que podría ser útil en el entrenamiento conductual
