According to a 2020 review in the journal *Nutrients*, low vitamin B12 levels are associated with a greater risk of developing a range of neurological issues beyond the common fatigue and nerve tingling. This highlights the importance of recognizing what are the rare symptoms of B12 deficiency to ensure timely diagnosis and treatment, which can prevent more severe complications.

Research indicates that up to 30% of older adults may suffer from a functional vitamin B12 deficiency. Understanding the wide-ranging clinical consequences of vitamin B12 deficiency is crucial, as this often-overlooked condition can severely impact the nervous system, blood cell production, and mental health.

According to a report from Harvard-affiliated Massachusetts General Hospital, a severe deficiency in Vitamin B12 can lead to serious neurological and psychiatric symptoms, including paranoia and delusions. While no specific vitamins can stop paranoia, addressing nutritional imbalances through a healthy *nutrition diet* can play a crucial supporting role in overall brain health and mental wellness alongside professional medical care.

Case reports have documented that paranoid psychoses can be caused by vitamin B12 deficiency, a condition that can affect the central nervous system even without anemia. Research shows that other nutritional inadequacies, such as low levels of zinc and vitamin D, may also contribute to or exacerbate paranoia and other psychiatric symptoms.

According to a 2024 systematic review, vitamin B12 deficiency is an increasingly recognized cause of hallucinations, particularly visual and auditory ones. This critical nutritional imbalance can profoundly affect neurological function and is a key answer to the question, "What deficiency causes visual hallucinations?".
