Some neurologists recommend medications typically prescribed for Alzheimer's disease to help a patient retrieve memories and ward off memory deficits immediately after a head injury. However, Dr. Hart emphasizes, these medications are prescribed off-label-meaning the FDA hasn't approved the drugs for this use.

There's no specific treatment for amnesia, but techniques for enhancing memory and psychological support can help people with amnesia and their families cope.
Most people with amnesia have problems with short-term memory — they can't retain new information. Recent memories are most likely to be lost, while more remote or deeply ingrained memories may be spared. 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. This affects memory-making parts of your brain, such as the thalamus. Anterograde amnesia tends to occur after you start experiencing some symptoms of the disease, such as short-term memory loss.
These can help them look for changes or damages to the brain. Amnesia is caused by brain damage. Treatment focuses on therapies and techniques that help improve quality of life.
Options include:. Mild brain injuries may lead to short-term memory loss and your symptoms may improve as your brain heals. Moderate to severe injuries can lead to permanent amnesia. Amnesia may be permanent, according to the Mayo Clinic. This means that symptoms of anterograde amnesia can worsen over time. However, symptoms can also improve or stay the same, even following a traumatic brain injury.
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. As a rule of thumb, you should always seek medical help for any unexplained memory loss or for recent head injuries. Your doctor can detect any changes in the brain and offer treatment recommendations when appropriate. Vitamin B deficiencies can cause a wide range of symptoms. Learn the importance of each B vitamin, their deficiency symptoms, and the best food….
Your hippocampus plays an important role in forming memories. Transient global amnesia TGA is a poorly understood condition. If you develop it, you will experience confusion or agitation that comes and goes repeatedly over the course of several hours. You may experience memory loss in the hours before the attack, and you will probably have no lasting memory of the experience. Scientists think that TGA occurs as the result of seizure-like activity or a brief blockage of the blood vessels supplying your brain.
It occurs more frequently in middle-aged and older adults. This common phenomenon is called infantile or childhood amnesia. To lose old memories, you must have widespread brain deterioration. People with dementia usually lose more recent memories first and keep older memories longer.
A depletion of oxygen levels can also affect your entire brain and lead to memory loss. This condition is called anoxia. Your hippocampus is a part of the brain and limbic system responsible for memory. Its activities include forming memories, organizing memories, and retrieving them when needed. When your hippocampus is impaired, you will have difficulty forming new memories. If your hippocampus is damaged in both halves of your brain, you can develop complete anterograde amnesia.
Traumatic head injuries, as well as stroke, tumors, and infections, can also cause damage to your brain. This damage can include permanent memory problems. Concussions commonly disrupt memories of the hours, days, or weeks before and after you were injured.
Short-term alcohol use can cause blackout. This is a temporary form of anterograde amnesia. Long-term alcoholism can cause Wernicke-Korsakoff syndrome. If you develop this condition, you will have difficulty forming new memories but may not be aware of it.
Severe trauma or stress can also cause dissociative amnesia.
