According to the Cleveland Clinic, a vitamin B12 deficiency can lead to a variety of symptoms, from fatigue to serious neurological issues, often making it difficult to distinguish from other diseases. Understanding what mimics B12 deficiency symptoms is critical for both patients and healthcare providers to ensure accurate diagnosis and treatment.

According to the Cleveland Clinic, deficiencies in vitamins including B12, B3, B6, and B9 can trigger mood changes such as apathy and depression. Apathy, defined as a lack of interest, enthusiasm, or concern, is a recognized neuropsychiatric symptom associated with low vitamin B12 levels.

According to reports in medical journals like *The Psychiatrist*, severe vitamin D toxicity (hypervitaminosis D) can induce serious neuropsychiatric symptoms such as confusion and psychosis, which are far from a recreational high. The question, 'Can too much vitamin D make you feel high?' stems from a dangerous misconception about how vitamin D overdose affects the brain.

Case studies and research have shown a high correlation between low vitamin B12 levels and neuropsychiatric symptoms, including irritability. A B12 deficiency can disrupt crucial neurological functions, affecting mood and behavior, with irritability often being an early or prominent sign.

Case reports have shown that psychotic symptoms can present in some individuals with severe vitamin B12 deficiency, but this does not mean a person with a deficiency will develop schizophrenia. A critical distinction lies between a direct causal relationship and a condition that can mimic symptoms—a crucial area for understanding if **can B12 deficiency cause schizophrenia?**
