Complications occur frequently, and include heart arrhythmia caused by enlarged atria with an increased tendency to atric fibrillation. Excessive training is common. This is detectable not only in an increased resting pulse, but also when the sufferer regularly falls asleep at parties («a social disaster»).
Many tend to have a problematic family and sex life. One heavily afflicted sufferer told me that his wife had given him an ultimatum: «The skis or me!» He told me that this was an easy choice: it ended in a ski-sm. Many sufferers do the Birkebeiner Ski Marathon. Before the start at Rena, many tend to have trouble expressing themselves clearly, so-called ski-sophasia. At the finish line in Lillehammer one can often observe post-Birkebeiner cramps or failure-to-win-the-badge depressions. Here, an increased risk of suicide should be taken into account. In serious cases an anti-depressive drug should be considered, preferably Ski-pramil or Ski-pralex. Some sufferers lose all contact with reality and develop ski madness, so-called ski-zophrenia. The preferred treatment is Ski-ordinol.
For skiencephalic persons, the summer season can be a major strain. Many suffer from abstinence and summer melancholia. Most of them dislike the sun and warm weather, since the sun is the bane of all snow. Many go chasing the snow, even in summer.
Most of the afflicted persons have run out of nourishment on at least one occasion. They will then eat anything available. One acquaintance told me that of all the ski waxes, green Swix had the best taste.
