Retrograde amnesia is a form of amnesia where someone is unable to recall events that occurred before the development of the amnesia, even though they may be able to encode and memorize new things that occur after the onset.
Nobody , was a man, in his late twenties and with a slight Yorkshire English accent but no other identification, who awoke in a Toronto hospital in with what appeared to be severe retrograde or global amnesia.
After various attempts to obtain Canadian citizenship and to legally change his name, he turned out to be a Romanian called Sywalkd Skeid , and to exhibit no clinical evidence of amnesia at all. The famous anterograde amnesia case is known as "H. 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.

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. There is currently no cure or treatment for this disease. Both large strokes and repeated small strokes can cause damage to the brain. Depending on where the damage occurs, memory problems may result.
Two types of memory that can be affected by stroke include verbal memory and visual memory. Any type of seizure can cause damage to the brain and cause memory problems. Some seizures affect the whole brain and some only affect a small area. Seizures in certain parts of the brain, especially the temporal and frontal lobes, are a common cause of memory problems in people with epilepsy.
Cardiac arrest causes people to stop breathing, which means their brain may be deprived of oxygen for several minutes. This can lead to serious brain damage, which may cause retrograde amnesia or other cognitive deficits. To diagnose retrograde amnesia, your doctor will need to perform a full medical exam to look for all the possible causes of memory loss. There are no specific medications used to treat retrograde amnesia. Generally, your treatment will focus on the underlying cause of the amnesia.
For example, if you have epilepsy, you and your doctor will work to reduce your number of seizures. Treatment for other types of dementia generally focus on support and coping. Some people with amnesia work with an occupational therapist to learn new information and try to replace what was lost. They work with the therapist to use their older, intact memories as a basis for storing new memories. Therapists can help people develop organizational strategies that make it easier to remember new information.
Someone may recall experiences from childhood or know the names of past presidents, but not be able to name the current president, know what month it is or remember what was for breakfast.
Isolated memory loss doesn't affect a person's intelligence, general knowledge, awareness, attention span, judgment, personality or identity. People with amnesia usually can understand written and spoken words and can learn skills such as bike riding or piano playing. They may understand they have a memory disorder.
Amnesia isn't the same as dementia. Dementia often includes memory loss, but it also involves other significant cognitive problems that lead to a decline in daily functioning.
A pattern of forgetfulness is also a common symptom of mild cognitive impairment MCI , but the memory and other cognitive problems in MCI aren't as severe as those experienced in dementia. Anyone who experiences unexplained memory loss, head injury, confusion or disorientation requires immediate medical attention.
A person with amnesia may not be able to identify his or her location or have the presence of mind to seek medical care. If someone you know has symptoms of amnesia, help the person get medical attention. Normal memory function involves many parts of the brain. Any disease or injury that affects the brain can interfere with memory. Amnesia can result from damage to brain structures that form the limbic system, which controls your emotions and memories.
These structures include the thalamus, which lies deep within the center of your brain, and the hippocampal formations, which are situated within the temporal lobes of your brain. Amnesia caused by brain injury or damage is known as neurological amnesia. Possible causes of neurological amnesia include:. Head injuries that cause a concussion, whether from a car accident or sports, can lead to confusion and problems remembering new information. This is especially common in the early stages of recovery.
Mild head injuries typically do not cause lasting amnesia, but more-severe head injuries may cause permanent amnesia. Another rare type of amnesia, called dissociative psychogenic amnesia, stems from emotional shock or trauma, such as being the victim of a violent crime. In this disorder, a person may lose personal memories and autobiographical information, but usually only briefly. Amnesia varies in severity and scope, but even mild amnesia takes a toll on daily activities and quality of life.
