Mental Confusion or Forgetfulness
Vitamin B12 deficiency is the most common vitamin deficiency in the United States. It can cause several symptoms, including forgetfulness. Furthermore, because B12 is only found in animal products, fortified foods, and a few plants such as alfalfa and tempeh, vegetarians and vegans may be more likely to have B12 deficiencies than omnivores.
A B12 deficiency can cause memory problems and confusion. Many people who believe they have a B12 deficiency have other types of dementia or brain damage. However, the two conditions share some symptoms, so it can be difficult for doctors to determine which one the patient has. In addition, people with a vitamin B12 deficiency may complain of brain fog, which includes forgetfulness, confusion, and difficulty concentrating.
People with cognitive dysfunction might get stuck on words while speaking or forget things they did or places they’ve just been to. These are symptoms of B12 deficiency but could also indicate other conditions that affect the brain, such as Alzheimer’s disease or traumatic brain injury (TBI).
