1.Pharmacological Treatment in Alcohol-induced Cognitive Disorder.
Journal of the Korean Medical Association 2008;51(1):84-89
Alcohol-induced cognitive disorder is a very severe problem in problem alcohol drinker and alcohol itself seems to be one of the main causalities in the development of senile dementia. However, the spectrum of alcohol induced cognitive disorder is quite broad, for example, it covered from alcohol-induced persistent amnestic disorder to Wernicke-Korsakoff syndrome and alcohol-induced persistent dementia. By that reason, broad spectrum of cognitive impairment by excessive alcohol drinking is regarded as alcohol related dementia. The pharmacological treatment is not well established yet in alcohol related dementia, except Wernicke-Korsakoff syndrome which is definitely related to thiamine deficiency. Therefore we introduced that some reports about the clinical efficacies by rivastigmine or donepezil trial and recent outcomes of memantine trial by authors in this review.

A 57-year-old man who was diagnosed with Wernicke-Korsakoff syndrome showed severe impairment of cognitive function and a craving for alcohol, even after sufficient supplementation with thiamine. After completing 10 sessions of 10 Hz repetitive transcranial magnetic stimulation (rTMS) at 100% of the resting motor threshold over the left dorsolateral prefrontal cortex, dramatic improvement in cognitive function and a reduction in craving for alcohol were noted. This is the first case report of the efficacy of a high-frequency rTMS in the treatment of Wernicke-Korsakoff syndrome.

Thiamine deficiency is known to lead to certain neurological sequelae including Wernicke-Korsakoff syndrome. Signs attributable to this condition include ataxia, ophthalmoplegia, nystagmus, and mental confusion. The prompt use of thiamine prevents progression of the disease and reverses those lesions that have not yet progressed to the point of fixed structual change. We have experienced a case of Wernicke-Korsakoff syndrome associated with hyperemesis gravidarum, which seemed to be developed by prolonged thiamine-free dextrose therapy, we emphasise the need for thiamine supplementation in hyperemesis gravidarum patient.

Despite epidemiological studies reporting no negative effects of mild to moderate alcohol drinking on cognitive functioning, a recent well-controlled study showed that chronic mild drinking diminished the volume of the brain and was associated with cognitive decline that worsened as a function of the amount of alcohol consumed. Animal studies have demonstrated that neural cell damage follows chronic alcohol intake and withdrawal. In addition, acute excessive alcohol intake has been shown to result in temporary impairment of memory, and chronic alcohol drinking is often related to neuronal damage and cognitive disorders. Even though a diverse spectrum of cognitive disorders can develop after sustained alcohol drinking, no definite diagnostic criteria existed before those proposed by Oslin; the availability of these criteria will provide more structured clinical and academic approaches to alcohol-related cognitive decline, including dementia. In general, diminished cognitive functioning has been related to excessive alcohol consumption, with cognitive functioning gradually recovering over time. With the exception of the administration of thiamine in Wernicke-Korsakoff syndrome, only supportive pharmacotherapies have been provided for patients with alcohol-related cognitive disorders. However, experimental trials with rivastigmine or donepezil have been conducted for special populations with persistent cognitive impairments, and these studies reported favorable outcomes. We administered memantine for alcohol-related dementia and observed improvements in verbal memory and scores on the mini-mental status exam. We anticipate that novel and appropriate therapeutic agents for various conditions in this domain will be developed based on systematic diagnostic criteria and the accumulation of neurobiological evidence about alcohol-related cognitive decline.

PURPOSE: The authors hereby describe a case of Wernicke-Korsakoff syndrome with accompanying ocular findings that is caused by hyperernesis gravidarum. METHODS: We experienced a 27-year-old female at 12 weeks of pregnancy, who visited our clinic because of weight loss, gait disturbance, decreased mentality and dizziness after prolonged vomiting for 2 months. Neurological examination demonstrated ataxia of gait and loss of orientation. Ophthalmologic examination showed decreased visual acuity, upbeat nystagmus, diplopia and retinal hemorrhage. RESULTS: We report a relatively rare case of Wernicke-Korsakoff syndrome with ophthalmic symptoms induced by hyperemesis gravidarum. CONCLUSIONS: If a pregnant women has symptoms of severe vomiting along with other ocular findings such as retinal hemorrhage or restricted extraocular movement, one must suspect the diagnosis of Wernicke-Korsakoff syndrome, and should start appropriate treatment immediately.

A 24-year-old pregnant woman started to have severe hyperemesis gravidarum at 6 weeks' gestation. Six weeks later, dizziness, ataxia, visual disturbance, diplopia and confusion were developed. On admission, she presented ophthalmoplegia, nystagmus, deaeased tendon reflex, intention tremor, ataxia, confusion and memory disturbance. She was diagnosed to Wernicke-Korsakoff syndrome and 100mg of thiamine was administered intravenously daily till 28 weeks gestation and then intramuscularly. Her ocular symptns, together with neurological signs, were gradually improved. Memory disturbance slightly improved but remained at the time of delivery. The case will be presented in more details with a brief revie of literatures.

Hypermesis gravidarum is a complication defined as vomiting severe enough to require hospital admission during early pregnancy. Thiamine deficiency is known to lead to certain neurological seguelae including Wernicke-Korsakoff syndrome. Wernicke's encephalopathy is an illness of acute onset characterized by global confusion, paralysis of eye ball movements, and gate ataxia due to a deficiency of thiamine. The immediate administration of thiamine prevents progression of the disease and reverses brain lesions that have not yet progressed to the point of fixed structural change. We have experienced a case of Wernicke-Korsakoff syndrome associated with hyperemesis gravidarum, which seemed to be developed by prolonged thiamine-free fluid therapy. We emphasize the need for thiamine supplementation in hyperemesis gravidarum patients.

Chronic alcohol use may have direct or indirect neurotoxic effects on the brain that can lead to cognitive impairment. However, the precise relationship between alcohol and dementia remains unclear. There are several epidemiological studies suggest that the protective effect of light-moderate alcohol drinking in dementia. But obviously the heavy alcohol drinking can lead to brain damage and increase the risk of various types of dementia. The clinicopathological issues and criteria regarding so-called 'alcoholic dementia' remain under debate. Alcohol-induced persisting amnestic disorder, alcohol-induced persisting dementia, and Wernicke-Korsakoff syndrome (thiamine deficiency) may constitute distinct disease entities, but they may also share some common features. Based on this theory, Oslin and colleagues proposed the broader diagnostic scheme and criteria for Alcohol Related Dementia (ARD), which may include cases of Wernicke-Korsakoff syndrome and also other cases of dementia that appear to be alcohol-related. In pathogenesis of the alcoholic dementia, the chronic exposure to ethanol results in the adaptive up-regulation of NMDA receptor sensitivity, which can result in an increased vulnerability to glutamate induced excitotoxicity. Despite the clinical importance of ARD, few medical treatments for ARD have been proposed and studied. Most of all, the gold standard of the treatment in alcoholic dementia is the maintaining abstinence. Some therapeutic trials with cholinesterase inhibitors (donepezil and rivastigmine) and memantine (NMDA receptor antagonist) have been conducted for the patients with Wernicke-Korsakoff syndrome and alcohol-related dementia, and these studies reported favorable outcomes. Especially memantine can be a more effective agent in the treatment of alcoholic dementia because of anti-craving effect reported in several studies.

Thiamine deficiency is known to lead to certain neurologic sequales including Wernicke-Korsakoff syndrome. Wernicke's encephalapathy is charac-terized by ataxia, ophthalmoplegia, nystagmus, and mental change. Although classically associated with chronic alcoholism, a number of other predisposing conditions exist such as hyperemesis gravidarum, thyrotoxicosis, starvation, anorexia nervosa, prolonged total parenteral nutrition, gastric plication and renal dialysis. We have experienced a case of Wernicke's encephalopathy associated with prolonged starvation which was misdiagnosed by hyponatremic ence-phalopathy at first, and which seemed to be developed by thiamine-free dextrose infusion in 39-year-old male patient. We report the case with review of the literature and emphasize the need for thiamine supplementation with slow correction of hyponatremia before the infusion of dextrose solution in the prolonged starved hyponatremic patient.

OBJECTIVE: To correlate the MRI findings in acute and chronic stage of Wemicke encephalopathy with the well-known clinical and pathologic findings. Background. Wemicke encephalopathy is an acute phase of Wemicke-Korsakoff syndrome. Pathologic findings change between acute and chronic phases. Only a few MRI studies have been done in this disease to date. METHODS: Ten consecutive patients with Wemicke encephalopathy were evaluated with MRI; seven within 24 hours of thiamine treatment, and three between 2 and 4 days. They presented with confusion, ophthalmoplegia and gait ataxia which improved with intravenous thiamine. Korsakoff psychosis became evident on followup. Tl-, proton- and T2-weighted axial images were obtained with additional 5 mmthick Tl-weighted sagittal and coronal images to evaluate the morphology and size of the mammillary body. RESULTS: Increased T2 signal was seen in the periaqueductal area in seven(sometimes involving superior colliculus); medial thalamus in five; and splenium of the corpus callosum in two. Among the seven patients with T2 signal abnormalities, five had follow-up MRI in 2 to 70 days, which showed complete resolution of the abnormalities. Seven patients showed atrophy of mammillary body on the initial MRI. In the three patients who had normal mammillary body in size on initial scan, follow up MRI revealed atrophic change of mammillary body. Tlweighted sagittal image showed superior cerebellar vermis atrophy in seven. Four patients revealed dilatation of the third ventricle. CONCLUSION: MRI findings of Wernicke encephalopathy appear diagnostic in acute stage and may reflect the pathological evolution in acute and chronic phases of Wernicke-Korsakoff syndrome.
