You can complete your general education classes before applying to nursing school. However, take only the courses required by the nursing schools to which you plan to apply. Competitive nursing schools may not accept your application if you submit a transcript with prerequisites the school doesn't require.
Abstract. Psychophysiological insomnia is arguably the most common form of insomnia, outside of insomnia âdue toâ medical or psychiatric illness.
Insomnia can be grouped into primary and secondary, or comorbid, insomnia. Primary insomnia is a sleep disorder not attributable to a medical, psychiatric, or environmental cause. It is described as a complaint of prolonged sleep onset latency, disturbance of sleep maintenance, or the experience of non-refreshing sleep.nsomnia can be classified as transient, acute, or chronic. 1  Transient insomnia lasts for less than a week. 2  It can be caused by another disorder, by changes in the sleep environment, by the timing of sleep, severe depression, or by stress.
