As mentioned, the main symptom is memory loss, particularly for events arising after the onset of the condition. Sometimes memories of the more distant past can also be affected. Lack of insight into the condition. Inventing events to fill the gaps in memory. This is more common in the early stages of the illness and is known as 'confabulation'.
Some people are apathetic, others are talkative and repetitive.
However, a positive feature is that people usually retain the skills they acquired before developing the disorder so they are often able to get by with appropriate support. They will also be observed to see whether their condition progresses without alcohol. If their condition does not change, they may be diagnosed with a form of dementia, such as Alzheimer's disease. It is possible to have both Korskoff's and a dementia. Women can also be affected.
