Overview

Anterograde amnesia refers to a decreased ability to retain new information. This can affect your daily activities. It may also interfere with work and social activities because you might have challenges creating new memories.

顺行健忘症是健忘症。In such cases, the amnesia (memory loss) has already occurred. It’s caused by damage to memory-making parts of your brain. In some cases amnesia may be temporary, but in other cases it may be permanent. Some types of therapies can help you cope with this type of memory loss.

Proactive, anterograde, and retrograde amnesia

Anterograde amnesia, according to theMayo Clinic，是健忘症的两个主要特征之一。具有此功能的人很难根据遇到的经验和信息来创造新的回忆。

The other feature is called retrograde amnesia. This refers to the inability to remember events and people from your past. It can also cause you to forget well-established daily information, such as what time you go to work.

Proactive amnesia is another term that refers to anterograde amnesia.

Amnesia is sometimes confused with失智。The latter is a degenerative disease that affects your memory and information about yourself. However, dementia also leads to brain damage that can lead to more cognitive challenges. Such challenges affect everyday functions, such as work and playing sports.

顺行健忘症更具体地涉及记住new信息。在这一点上，您可能已经难以长期记忆了。

顺行健忘症的症状主要影响短期记忆加工。这可能会引起混乱和沮丧。例如，有这种失忆症形式的人可能会忘记：

  • someone they’ve recently met
  • 一个新电话号码
  • a recent meal
  • 名字的名字
  • newly made changes to a routine, such as school or job changes

这种症状与逆行性健忘症不同，这可能包括忘记您在失忆症之前已经知道的信息。例如，您可能会忘记阅读以前阅读的书。此外，发生了遗忘症的症状后你已经开始出现记忆丧失。

2010年发表的一项研究 Neuropsychology found that 7 out of 10 patients with anterograde amnesia were capable of temporarily retaining new information. However, a phenomenon called “retroactive interference” occurred. This is when new information interferes with the previously memorized information. For example, you might remember a number, but learn a new number shortly after, which cancels out the original information.

总体而言，失忆症是由对大脑损害造成的。这会影响大脑的记忆力部分，例如丘脑。在您开始经历某些疾病症状（例如短期记忆力丧失）之后，顺行健忘症往往会发生。这是由于对大脑的一定损害造成的，导致保留新信息的方式差异。

MRI测试或CT扫描可以帮助您的医生诊断出恢复顺行性健忘症的身体原因。这些可以帮助他们寻找对大脑的变化或损害。

健忘症是由脑损伤引起的。目前没有可以治愈失忆症的治疗方法，而是疗法集中在疾病管理上。

治疗重点是有助于改善生活质量的疗法和技术。选项包括：

  • 维生素B1补充剂, in case of a deficiency
  • occupational therapy
  • memory training
  • 技术帮助，例如提醒应用程序

目前没有FDA批准的药物来治疗失忆症。

Your risk for developing any form of amnesia may increase if you’ve had one or more of the following:

轻度的脑损伤可能导致短期记忆力丧失，并且随着大脑愈合而导致的症状可能会改善。中度至重度受伤会导致永久性失忆症。

Amnesia may be permanent, according to theMayo Clinic。这意味着随着时间的流逝，顺行健忘症的症状可能会恶化。但是，即使脑部受伤，症状也可以改善或保持不变。

Some cases of amnesia are temporary. Known as transient global amnesia, temporary memory loss may improve after an injury or illness. However, anterograde amnesia is most often associated with permanent memory loss.

根据经验，您应始终寻求医疗帮助，以确保任何无法解释的记忆丧失或最近的头部受伤。您的医生可以检测到大脑的任何变化，并在适当时提供治疗建议。
