Hyperthymesia is a form of pathological hypermnesia that is also called hyperthymestic syndrome. Neither the underlying cause nor the disease process are currently known. This condition is characterized by great episodic memory capacity, that is the inability to forget autobiographical memories, which then pervade a large amount of the patient's thoughts. Sufferers remember all the events of their life, no matter how old, down to the smallest detail.
