Mean Scale Score for CSTs. This is the arithmetic mean or average of the scale scores for all students who took each grade-and/or content-specific CST without modifications. The scale scores for each grade and subject area range between 150 (low) to 600 (high).
Causes of central precocious puberty can include: 1  damage to the inhibitory system of the brain (due to infection, trauma, or irradiation), 2  hypothalamic hamartoma produces pulsatile gonadotropin-releasing hormone (GnRH), 3  Langerhans cell histiocytosis, or.  McCuneâAlbright syndrome.
In precocious puberty, there is early activation of nerve cells in the hypothalamus producing gonadotrophin-releasing hormone or excess gonadotrophin production from the pituitary gland as a result of a pituitary tumour. In both cases, the pattern of pubertal development is usually normal, but premature or precocious.
