Positive occipital sharp transients of sleep (POSTS) are well recognized as a normal electroencephalographic phenomenon in young to middle-aged persons, but little comment has been made concerning their occurrence in geriatric age groups. This study encompassing 365 electroencephalograms, showing POSTS among patients aged 22 to 86 years, demonstrates that the presence of POSTS is not an age limited occurrence, but extends over a wide age range into the later decades of life. Though the incidence of POSTS declined with advancing age, the diminution was not striking until after age 70. POSTS appeared only in normal and mildly abnormal EEGs. POSTS did not occur in markedly abnormal EEGs, and thus they resemble other features of normal sleep including sleep spindles and K-complexes.
枕区睡眠期阳性尖波（POSTS）在中青年人群中被公认为是一种正常的脑电图现象，但关于其在老年人群中的出现情况却鲜有评论。这项研究涵盖了365份脑电图，这些脑电图来自年龄在22岁至86岁之间且显示有POSTS的患者，结果表明POSTS并非仅限于特定年龄出现，而是在很宽的年龄范围内都会出现，一直到生命的后几十年。虽然POSTS的发生率随年龄增长而下降，但直到70岁以后这种下降才较为明显。POSTS仅出现在正常和轻度异常的脑电图中。POSTS不会出现在明显异常的脑电图中，因此它们类似于正常睡眠的其他特征，包括睡眠纺锤波和K复合波。
