1 : Wernicke-Korsakoff syndrome
2 : Overview Wernicke-Korsakoff syndrome is a brain disorder due to thiamine deficiency.
3 : Symptoms *Inability to form new memories *Loss of memory, can be severe *Loss of muscle coordination (ataxia) *Unsteady, uncoordinated walking *Making up stories (confabulation) *Seeing or hearing things that aren't really there (hallucinations) *Vision changes & Abnormal eye movements *Double vision & Eyelid drooping
4 : Treatment *Comatose & Lethargic *Unconscious & Confusion or delirium *Difficulties with vision and eye movement *Lack of muscle coordination The goals of treatment are to control symptoms as much as possible and to prevent the disorder from getting worse. Some people may need to stay in the hospital early in the condition to help control symptoms. Monitoring and special care may be needed if the person is:
5 : Causes Wernicke's encephalopathy and Korsakoff syndrome are believed to be two stages of the same condition. Wernicke's encephalopathy is caused by damaging changes in the brain, usually due to a lack of vitamin B1 (thiamine).A lack of vitamin B1 is common in people with alcoholism. Heavy alcohol use affects the breakdown of thiamine in the body. Even if someone who drinks alcohol heavily follows a well-balanced diet, most of the thiamine is not absorbed. Korsakoff syndrome, or Korsakoff psychosis, tends to develop as Wernicke's symptoms go away. Korsakoff psychosis involves damage to areas of the brain involved with memory.
6 : Tests & diagnosis *Decreased or abnormal reflexes *Problems with walk (gait) and coordination *Muscle weakness and atrophy (loss of tissue mass) *Abnormal eye movement & Long-term dialysis *Low blood pressure & Low body temperature *Fast pulse (heart rate) & Pyruvate *Serum B1 levels & Transketolase activity *AIDS & Cancers that have spread throughout the body *Extreme nausea and vomiting during pregnancy (hyperemesis gravidarum) *Heart failure (when treated with long-term diuretic therapy) *Long periods of intravenous (IV) therapy without receiving thiamine supplements *Very high thyroid hormone levels (thyrotoxicosis)
7 : Prognosis Without treatment, Wernicke-Korsakoff syndrome gets steadily worse and can be life threatening. With treatment, you can control symptoms (such as uncoordinated movement and vision difficulties), and slow or stop the disorder from getting worse. Some symptoms -- especially the loss of memory and thinking skills -- may be permanent. Other disorders related to alcohol abuse may also occur.
8 : Prevention Not drinking alcohol or drinking in moderation and getting enough nutrition reduce the risk of developing Wernicke-Korsakoff syndrome. If a heavy drinker will not quit, thiamine supplements and a good diet may help prevent this condition, but not if damage has already occurred.
9 : Complications *Alcohol withdrawal *Difficulty with personal or social interaction *Injury caused by falls *Permanent alcoholic neuropathy *Permanent loss of thinking skills *Permanent loss of memory *Shortened life span
10 : When to contact a doctor Call your health care provider if you have symptoms of Wernicke-Korsakoff syndrome, or if you have been diagnosed with the condition and your symptoms get worse or return. Also call if new symptoms develop, especially symptoms of alcohol withdrawal. Alcohol withdrawal can be fatal, so call the local emergency number (such as 911) or go to the emergency room if any severe symptoms occur . Symptoms of alcohol withdrawal include:
