A deficiency in vitamin B12 can lead to cognitive impairment, including forgetfulness and confusion, which may be mistaken for dementia. Unlike dementia, this condition is reversible with proper treatment. Older adults, individuals on specific medications like metformin or proton pump inhibitors, and those with gastrointestinal issues or who have undergone stomach surgery are at higher risk. Symptoms can include fatigue, mental fogginess, and in severe cases, paranoia, all of which can be confused with dementia symptoms. AI
