These incidents do not usually occur but they can happen. He possibly will not be able to learn skills that are not familiar to him before the incident, and may not be able to remember experiences that may happen on the same day and so on. It is, nevertheless, traumatic because it can hinder even simple daily tasks. Anterograde and retrograde amnesia can both be present in one individual which makes it very difficult to deal with.
The management for both anterograde and retrograde amnesia is significantly complex and cannot be summarized. The disorder should be assessed from all angles, and the management must be introduced in the same approach. For home care, the most essential thing is the patience and support that the family and friends provide to the patient.
Anterograde amnesia, on the other hand, involves the lack of the ability to form the latest memories of all varieties after the disorder developed. The conditions are both very serious and they differ accordingly. The person may not be able to recognize a number of people and will not have even a single memory about them; he can lose some essential skills such as encoding in retrograde amnesia. In anterograde amnesia, he possibly will not be able to learn skills that are not familiar to him before the incident, and may not be able to remember experiences that may happen on the same day and so on.

People with retrograde amnesia have trouble accessing memories from before the onset of amnesia. Retrograde amnesia is usually temporally graded, which means that your most recent memories are affected first and your oldest memories are usually spared.
The extent of retrograde amnesia can vary significantly. Some people may only lose memories from the year or two prior to having the injury or disease.
Other people may lose decades of memories. But even when people lose decades, they typically hang on to memories from childhood and adolescence. Focal retrograde amnesia, also known as isolated or pure retrograde amnesia, is when someone only experiences retrograde amnesia with few or no symptoms of anterograde amnesia.
This means that the ability to form new memories is left intact. This is a rare type of retrograde amnesia resulting from an emotional shock. Symptoms include:. Retrograde amnesia can result from damage to different parts of the brain responsible for controlling emotions and memories. These include the thalamus , which is deep in the center of the brain, and the hippocampus , which is in the temporal lobe.
Most traumatic brain injuries are mild, resulting in concussion. But a severe injury, like a serious blow to the head, can damage the memory-storing areas of the brain and lead to retrograde amnesia.
Depending on the level of damage, the amnesia could be temporary or permanent. Check out the best traumatic brain injury blogs of the year. Thiamine deficiency, which is typically caused by chronic alcohol misuse or serious malnutrition, can lead to a condition called Wernicke encephalopathy. If left untreated, Wernicke encephalopathy progresses into a condition called Korsakoff psychosis , which presents with both anterograde and retrograde amnesia.
Learn the symptoms of a vitamin B deficiency. Encephalitis is inflammation in the brain caused by a viral infection, such as herpes simplex.
It can also be caused by a cancer-related or non-cancer-related autoimmune reaction. This inflammation can cause damage to the memory-storing parts of the brain.
Below infographic shows more details of the difference between anterograde and retrograde amnesia. Anterograde amnesia and retrograde amnesia are two major types of amnesia. Anterograde amnesia refers to the incapability of forming new memories due to brain damage while retrograde amnesia refers to the incapability of recalling past memories due to brain damage.
Thus, this is the key difference between anterograde and retrograde amnesia. Barclay, Rachel. Org, , Available here. Samanthi Udayangani holds a B. Degree in Plant Science, M.
