Wernicke-Korsakoff syndrome: Year of the Zebra

Watch video only
Wernicke-Korsakoff syndrome is a rare neurological condition that causes degeneration of brain cells, or neuronal atrophy.
It is caused by thiamine, or vitamin B1, deficiency. Thiamine is a vitamin absorbed in the intestines and used for energy metabolism to support growth, development, and cellular functioning, especially in the brain and nervous system.
Thiamine deficiencies are commonly seen with conditions that lead to malnutrition, such as chronic alcohol use. The condition includes two stages: Wernicke encephalopathy, which is the acute and reversible stage; and Korsakoff syndrome, which is when the condition progresses to a chronic and irreversible stage.Now, Wernicke-Korsakoff syndrome commonly presents with the triad of altered mental status, including confusion and memory deficits; nystagmus, or involuntary, rapid, and repetitive movement of the eyes; and ataxia, or impaired coordination of voluntary movements, balance, and speech.
Other symptoms that may develop include agitation, hallucinations, and confabulation, which is when affected individuals create stories they believe to be true, to fill gaps in their memory.
The diagnosis of Wernicke-Korsakoff syndrome is typically based on the individual’s history and physical examination. Laboratory tests like a complete blood count, liver function tests, and thiamine levels are also commonly done.
In some cases, diagnosis may be confirmed with an MRI of the brain showing degeneration of the mammillary bodies, which are two areas in the brain responsible for memory.Now, the treatment for Wernicke encephalopathy is to consider it a medical emergency; and it must be addressed immediately to prevent the development of Korsakoff syndrome.
Treatment involves intravenous thiamine administration as soon as there is clinical suspicion of Wernicke-Korsakoff syndrome.
If Wernicke encephalopathy is treated promptly, affected individuals can begin to improve within two to three weeks of treatment.
However, if Wernicke encephalopathy progresses to Korsakoff syndrome, affected individuals may require life-long treatments that include oral thiamine and rehabilitation.
##SummaryAlright, as a quick recap, Wernicke-Korsakoff syndrome is a rare neurological condition that causes neuronal atrophy due to thiamine, or vitamin B1, deficiency and is commonly seen in chronic alcoholism.
It consists of a classic triad of altered mental status, nystagmus, and ataxia. Diagnosis is usually based on clinical evaluation.
Lastly, treatment involves the prompt administration of thiamine, addressing any underlying cause, and long-term care as needed.
