Neurologist Warns of Serious Cognitive Effects from Vitamin B12 Deficiency

A Slovak neurologist has outlined the severe neurological consequences of vitamin B12 deficiency, describing how the condition can progress from fatigue to severe dementia. According to the medical expert, when the brain lacks sufficient vitamin B12, nerve cells enter a hibernation-like state that causes noticeable personality and cognitive changes in patients. The neurologist detailed the progression of symptoms, explaining how untreated B12 deficiency can lead to increasingly serious neurological complications, ultimately resulting in severe cognitive impairment and dementia-like conditions.
