<unk>  encephalopathy is a severe syndrome characterised by ataxia, ophthalmoplegia, confusion and loss of short-term memory.
It is linked to damage to the medial thalamic nuclei, mammillary bodies, periaqueductal, and periventricular brainstem nuclei , and superior cerebellar vermis.  In the brain, it is the result of inadequate intake or absorption of thiamine (Vitamin B) coupled with continued carbohydrate ingestion.
The most common cause of an onset is prolonged alcohol consumption that is sufficient enough to cause a thiamine deficiency. Alcoholics are therefore particularly at risk, but it may also occur due to other causes of malnutrition. Other causes of thiamine deficiency may be found in patients with carcinoma, chronic gastritis, or continuous vomiting.
