Even with treatment, some symptoms, such as gait changes, confabulation, or memory loss, may not improve. The neuropsychology of WKS has been the subject of more extensive investigation. Patients typically demonstrate profound anterograde amnesia and impaired recall of past events, with a temporally graded deficit in which recall is better for more remote time periods 58.

It accounts for only 3 to 5 percent of dementia cases overall, though it’s responsible for a higher number, as many as 10 percent, of those with the early-onset form of dementia.
Condition Spotlight
It is well established that excessive and prolonged alcohol use can lead to permanent damage to the structure and function of the brain 1. Despite this, there is little consensus on the characteristics of a dementia syndrome related to sustained alcohol abuse or its relationship to Wernicke-Korsakoff syndrome (WKS). After a long period of neglect, research interest has increased in recent years and has been spurred on by clinical demand, increased reported rates of alcohol abuse in older people, and alcohol related dementia increasing alcohol consumption by women 2, 3. In this paper, we aim to review the neuropathology, nosology, epidemiology, clinical features, and neuropsychology of alcohol-related dementia (ARD) and WKS.
Korsakoff syndrome symptoms
Cognitive and behavioral changes specific to ARD have received limited investigation. However, the ARD groups had poorer performance on visuospatial measures, including clock drawing and copying tasks. Deficits on tasks of working memory 44, motor speed 34, and executive Sobriety function (verbal abstract reasoning 44 and letter fluency 34) have also been observed in ARD samples in comparison with healthy controls. This was supported by a recent SPECT (single-photon emission computed tomography) study that reported reduced regional cerebral blood flow in the frontal cortices, basal ganglia, and thalami of patients with ARD 42. While some damage may be irreversible, treatment for Korsakoff syndrome is focused on managing symptoms and preventing further progression. High-dose thiamine is usually given, via injections, especially in the early stages, and stopping alcohol use entirely is critical to prevent further brain damage.
- SLPs use spaced-retrieval training to support safety information and memory therapy to maintain meaningful social connections.
- Nutritional support is important, particularly thiamine (Vitamin B1) supplementation, as deficiencies in this vitamin are common among individuals with alcohol dependence and contribute to cognitive impairments.
- Evidence also suggests that people who regularly drink heavily are more likely to develop Alzheimer’s earlier in life.
When someone loses the ability to speak fluently, they often withdraw, so therapy helps rebuild that community. Several high-profile reviews looked at the research into alcohol and dementia risk. They all found that people who drank heavily or engaged in binge drinking were more likely to develop dementia than those who drank only moderate amounts. A small number of studies seem to suggest that drinking moderate amounts of alcohol reduces dementia risk compared to not drinking at all.
Outpatient treatment involves going to regular physical and mental health appointments to get treatment and learn how to overcome alcohol addiction while otherwise keeping any work and social obligations. Inpatient treatment requires more dedication and involves living in a rehab center to get intensive treatment that is more likely to have a lasting effect. No matter the duration, rehab can be an essential step toward regaining control over one’s life.
