Positive Occipital Sharp Transients of Sleep are typically found in which age group?

Positive Occipital Sharp Transients of Sleep (POSTS) are a distinctive type of brainwave pattern observed during sleep, particularly during NREM sleep stages. These patterns are typically present in the sleep EEG of children and adolescents, especially between the ages of 1 and 12 years.

While the age group 13 to 25 years does include some overlap with adolescence, the patterns are more commonly associated with an earlier age range where they are seen prominently. As individuals progress into their teenage years and early adulthood, particularly past the age of 12, the prevalence of these transient sharp waves decreases significantly. Therefore, the focus on the earlier ages is essential for correctly identifying the typical age group associated with POSTS.

In summary, the observation of Positive Occipital Sharp Transients of Sleep predominantly in younger individuals explains why the age group of 0 to 12 years old is the most accurate answer to this clinical question regarding transient patterns in an EEG.
