Korsakoff Syndrome. Korsakoff syndrome is a chronic memory disorder caused by severe deficiency of thiamine (vitamin B-1). Korsakoff syndrome is most commonly caused by alcohol misuse, but certain other conditions also can cause the syndrome.
While Wernicke-Korsakoff syndrome is sometimes referred to as alcoholic dementia or alcohol related dementia, it is caused by thiamine deficiency, rather than being a direct result of alcohol abuse. Wernicke's encephalopathy affects eye movement and vision, balance and coordination, and causes confusion.
Alcohol-related 'dementia' is a type of alcohol-related brain damage (ARBD). If a person has alcohol-related 'dementia' they will struggle with day-to-day tasks. This is because of the damage to their brain, caused by regularly drinking too much alcohol over many years.
Alcoholic Dementia Life Expectancy
While there are no specific life expectancy projections for alcohol-related dementia in general, a study shows that the life expectancy for someone with Wernicke-Korsakoff Syndrome is eight years for 50% of people who have this form of alcohol-related brain damage.
Overall, 50% of patients would be expected to die within 8 years of WE episode and main causes of death included serious bacterial infections (44.5%) and cancer (33.3%).
People who are diagnosed with ARBD are usually aged between about 40 and 50. This is younger than the age when people usually develop the more common types of dementia, such as Alzheimer's disease. It is not clear why some people who drink too much alcohol develop ARBD, while others do not.
Excessive alcohol consumption over a lengthy time period can lead to brain damage, and may increase your risk of developing dementia. However, drinking alcohol in moderation has not been conclusively linked to an increased dementia risk, nor has it been shown to offer significant protection against developing dementia.
WKS consists of two stages: Wernicke encephalopathy, a sudden and severe (acute) brain disorder. Korsakoff syndrome, a long-term (chronic) memory disorder.
An individual with Wernicke-Korsakoff syndrome classically presents with (1) ocular disturbances which may include diplopia, painless vision loss, or strabismus, (2) gait abnormalities that include a wide-based, short-stepped gait and an inability to stand or ambulate without assistance, and (3) mental status changes ...
The main difference between this Alcohol-related Dementia and Vascular Dementia is their cause and alcohol-induced Dementia can regress whilst the latter can't.
Alcoholic Korsakoff's syndrome is characterized most notably by cognitive impairments in memory (i.e., anterograde amnesia—an inability to remember new information for more than a few seconds) as well as deficits in abstraction and problem-solving (Jacobson et al. 1990).
Alcoholism plus dementia causes faster decline in skills needed to function independently, worsens behavioral problems, and raises safety concerns for the person with dementia and the people caring for them. Alcohol and medication are also a dangerous combination.
First there will be a brief time when a person has intense inflammation (swelling) of their brain. This is known as 'Wernicke's encephalopathy'. If this condition isn't treated quickly, the person may develop a more long-term condition called 'Korsakoff's syndrome'. This has many of the same symptoms of dementia.
The disorder affects slightly more males than females, and is evenly distributed between ages 30 and 70.
There are three main types of alcohol related brain damage; Wernicke's encephalopathy, Korsakoff's syndrome and alcoholic dementia. Both Wernicke's and Korsakoff's can occur singularly or in combination when it is called Wernicke-Korsakoff syndrome.
In this nationwide cohort study, we found that sustained mild drinkers had a 21% decreased risk of all-cause dementia, and sustained moderate drinkers had a 17% decreased risk of all-cause dementia compared with sustained nondrinkers, whereas sustained heavy drinkers had an 8% increased risk.
The cerebellum, an area of the brain responsible for coordinating movement and perhaps even some forms of learning, appears to be particularly sensitive to the effects of thiamine deficiency and is the region most frequently damaged in association with chronic alcohol consumption.
Aging can lower the body's tolerance for alcohol. Older adults generally experience the effects of alcohol more quickly than when they were younger. This puts older adults at higher risks for falls, car crashes, and other unintentional injuries that may result from drinking.
The risk of dementia was greater among alcohol abstainers than occasional, light-moderate-, and moderate-heavy drinkers, as well as among men. Notably, this result was consistent among female subjects when fully adjusted and competing risk models were employed.
Alcohol overdose can lead to permanent brain damage or death.
The cognitive deficits seen in Korsakoff syndrome are thought to be primarily due to damage to the following areas- the anterior nucleus of the thalamus, mammillary bodies, and corpus callosum.
Without treatment, Wernicke-Korsakoff syndrome gets steadily worse, and can be life threatening. With treatment, it is possible to control symptoms (such as uncoordinated movement and vision difficulties). This disorder can also be slowed or stopped.
