If you suffer from memory loss, you may have a difficult time remembering where you placed something, a recent conversation or something that happened years ago. Memory loss can occur as the result of several factors, such as an illness, medication and head injury. Deficiencies in certain vitamins and minerals can result in a condition called metabolic-related dementia, in which you have significant memory loss, according to NetWellness. These nutritional deficiencies can result from a poor diet or a condition that interferes in your absorption of these nutrients.
Vitamin B1
Your body uses vitamin B1, also known as thiamine, to maintain your nervous system function. If you do not have enough of this vitamin in your diet, you may suffer from memory loss. Foods, such as pork, whole grains, legumes and rice, contain vitamin B1. The University of Maryland Medical Center notes that a deficiency in vitamin B1 can occur in alcoholics. If you drink heavily and have a vitamin B1 deficiency, you may develop a condition called Wernicke-Korsakoff syndrome. A two-part disorder, Wernicke-Korsakoff syndrome starts with Wernicke's encephalopathy, in which you have confusion and changes in your vision. When the disorder progresses to Korsakoff syndrome, memory loss occurs, in which you cannot remember the past and cannot create new memories. Due to the memory loss, Wernicke-Korsakoff syndrome patients confabulate, in which they make up stories.
Vitamin B6
Vitamin B6 plays several roles in the brain, such as helping with the formation of the neurotransmitter serotonin. The vitamin occurs naturally in several types of foods, such as fortified cereals, chicken, potatoes and salmon. Without enough vitamin B6 in your diet, you may experience some problems with your memory. For example, patients with Alzheimer's disease, a type of dementia, have a deficiency in vitamin B6, along with other vitamins associated with memory, according to the Linus Pauling Institute. While vitamin B6 supplements may help with memory, not enough evidence exists to prove its effectiveness.
Niacin
Niacin occurs in several different groups of food, such as peanuts, turkey, salmon, enriched pasta, lentils and brewed coffee. You may develop a niacin deficiency if you do not eat enough niacin-rich foods or if you have a condition that affects your absorption of tryptophan, which your body uses to make the coenzyme nicotinamide adenine dinucleotide, which is from a derivative of niacin, notes the Linus Pauling Institute. If you have a severe niacin deficiency, you can develop a condition called pellagra in the late stage of the deficiency. Pellagra affects several parts of your body, including your nervous system. This can result in memory loss, as well as disorientation, fatigue and depression.
Folate
Besides causing a vitamin B1 deficiency, alcoholism can also cause a deficiency in folate. A folate deficiency can also occur if you do not eat enough foods that contain the vitamin, such as lima beans, spinach, lentils and pasta. The Linus Pauling Institute notes that people who had lower levels of folate had a increased risk of problems with their short-term memory.
Vitamin B12
Vitamin B12 is another B vitamin associated with memory loss. Foods, such as milk, salmon, clams, chicken and beef, contain vitamin B12. Not eating enough of these foods or having a condition that causing malabsorption of vitamin B12 can result in a deficiency. A vitamin B12 deficiency can affect the nervous system, causing damage to the nerves, as well as memory loss and dementia. Treating your memory loss with vitamin B12 supplements, even if it is the cause, may not also reverse the damage, according to the Linus Pauling Institute.
Iron
The Centers for Disease Control and Prevention notes that in the United States, the most common nutritional deficit is iron deficiency. This deficiency can occur if your body needs extra iron and you do not increase your intake or if you do not absorb enough iron. Clams, soybeans, beef, white beans and fortified cereals all contain iron. If you are a teenager, a deficiency in iron can cause memory problems. An iron deficiency can also cause fatigue and problems with work performance.
Vitamin E
Another vitamin deficiency that can result in a metabolic-related dementia is a vitamin E deficiency, according to NetWellness. An antioxidant, vitamin E helps protect your body from free radicals. Several foods, such as vegetable oils, corn, olives, spinach and wheat germ, provide vitamin E. MedlinePlus adds that while the mechanism is not known, vitamin E may help fight dementia.
