Can You Lose Track Of The Day Because Of Lack Of B12?

I asked Google AI, the title of this post and received this answer.

Yes, you can absolutely lose track of the day, forget appointments, or feel generally disoriented due to a lack of vitamin B12.
Vitamin B12 is crucial for nerve function and cognitive health, and a deficiency often manifests as “brain fog,” memory loss, confusion, and difficulty concentrating.

Here is how a B12 deficiency can affect your sense of time and mental clarity:

Brain Fog and Confusion: A common symptom of low B12 is a feeling of mental sluggishness, confusion, or lack of focus, often described as “brain fog”.

Memory Issues: It can cause significant forgetfulness or memory lapses, making it difficult to remember what day it is, what you are doing, or what tasks you have completed.

Cognitive Decline: Long-term, untreated deficiency can lead to severe cognitive impairment that may mimic dementia or Alzheimer’s in older adults.

Gradual Onset: Because the body stores B12 in the liver (often enough for 2–5 years), the deficiency develops slowly. As a result, you might not notice the gradual loss of mental sharpness or confusion until it starts significantly impacting your daily life.

The source of the report was the NHS web site.
