Vitamin B12 deficiency can cause dementia-like symptoms

He was then treated with B12 deficiency, along with doxepin and lorazepam, which are used to treat depression and anxiety.

Approximately five weeks later, the patient showed a significantly better performance IQ and improved cognitive speed.

It’s important to note that the case report does not conclusively show that B12 deficiency was the primary cause of the man’s decline but it strongly suggests the vitamin contributed.

More research needs to be carried out to understand the link but it’s yet more evidence of a worrying trend.

For example, patients with Alzheimer’s disease have been found to have lower vitamin B12 levels compared to patients without dementia.
