Alcohol Related Dementia

What is Korsakoff’s Syndrome and alcohol related dementia?

Excessive alcohol consumption can lead to certain forms of dementia, including Wernicke–Korsakoff syndrome. This condition occurs when alcohol interferes with the body’s ability to absorb thiamine (vitamin B1), a nutrient essential for healthy brain function. A deficiency in vitamin B1 can cause severe and long-lasting damage to the brain. Wernicke–Korsakoff syndrome progresses through two distinct stages.

What are the two stages of Wernicke–Korsakoff syndrome?

The first stage, known as ‘Wernicke’s encephalopathy’, involves intense inflammation of the brain over a brief period. Without prompt treatment, this condition can evolve into a more persistent and debilitating disorder called ‘Korsakoff’s syndrome’, which shares many symptoms with dementia.

Can you recover from Wernicke–Korsakoff syndrome?

Recovery from Wernicke–Korsakoff syndrome varies. About 25% of those who receive treatment experience a full recovery, while around 50% make a partial recovery and require ongoing support. Unfortunately, the remaining 25% may not recover and could need long-term care in a specialist residential care home.

What causes Wernicke encephalopathy?

Wernicke’s encephalopathy arises when the brain doesn’t receive enough thiamine, often due to excessive alcohol consumption. Alcohol hinders the absorption of thiamine in the gut, preventing it from being used effectively by the body and increasing its loss through urine.

What are the symptoms of Wernick’s encephalopathy?

Recognising the symptoms of Wernicke’s encephalopathy can be challenging, especially if the person is still intoxicated. Symptoms can sometimes be mistaken for alcohol withdrawal and include:

• Disorientation, confusion of mild memory loss
• Difficulty controlling eye movements
• Poor balance, being unsteady and walking with their legs apart
• Undernourishment

While not everyone with Wernicke’s encephalopathy will display all these symptoms, most will experience disorientation and confusion. Given the seriousness of this condition, diagnosis typically occurs in a hospital, where doctors may also perform a brain scan to confirm their diagnosis.

Is there a treatment for Wernicke’s encephalopathy?

Yes, there is a treatment. The individual must immediately stop drinking alcohol and will be given several injections of high doses of thiamine and other B vitamins.

What is Korsakoff’s Syndrome?

Korsakoff’s syndrome is a long-term condition that develops if Wernicke’s encephalopathy is not treated promptly. Over time, the brain damage becomes more challenging to reverse.

What are the main conditions of alcohol related dementia?

The primary symptoms of Korsakoff’s syndrome include confusion and memory loss, particularly concerning events that occurred after the onset of the condition. Individuals may repeatedly ask the same questions, as they are unable to form new memories. In some cases, memories from the distant past may become distorted or lost.

Other symptoms include:

• Difficulty understanding new information or learning new skills
• Changes in personality – the person may become apathetic (lacking emotional reactions), become very talkative, or do the same things over and over
• Lack of insight into their condition
• Confabulation – a person’s brain might fill gaps in their memory with things that didn’t happen. It is important to remember that the person thinks this is a real memory. It may seem that they are purposefully lying, but often this isn’t the case.
• Problems with concentration, planning, making decisions or solving problems.

How do individuals get diagnosed with Korsakoff’s syndrome?

A person may be diagnosed with Korsakoff’s syndrome if they show some of the symptoms and have a history of drinking too much. A brain scan can be helpful but is not always necessary. People with Korsakoff’s syndrome are often diagnosed in hospital after they have been admitted for other medical reasons.
