Vitamin B12 deficiency: Study shows personality disorder, other uncommon symptoms linked to this
The link between vitamin deficiency and neurological disorders cannot be imagined. However, vitamin B12 deficiency can lead to some neurological side effects. A 2018 study found a rare association of acute paroxysmal psychosis, brain atrophy, severe anemia with coronary insufficiency, and premature graying of hair in a 55-year-old man with vitamin B12 deficiency. .
The patient presented with complaints of unrelated talking for 10 days. The study report states that he was advised by his cardiologist to have a coronary angiogram because there was evidence of coronary insufficiency in his electrocardiogram. His memory is disturbed, his judgment is impaired, and his personality changes because he becomes isolated, apathetic and withdrawn. He also doesn’t want to think and get depressed, the report added.
