Discussion
Different types of insomnia react differently when exposed to other factors such as MDD for example it does not in any way cause primary insomnia however in cases of secondary insomnia, it is considered as being the most crucial factors based on studies related to DSM.
This study did not really determine whether a correlation exists between insomnia and depression since they have common symptoms, yet the use of BD1-II did perceive the symptoms of depression in insomniacs.
The PSQI has a high sensitivity and specificity for
insomnia patients in comparison to healthy controls, thus
underscoring that it is a good measure for differentiating
between good sleepers and patients suffering from sleep
disturbances. Our data suggest, however, that the cut-off
score should be set to 6 in order to maximize specificity
while only modestly reducing sensitivity. In sum, the PSQI
proved to be a valuable adjunct to clinical work on insomnia
and is a useful first-line, easy-to-handle, and time-efficient
questionnaire to evaluate sleep disturbances.
