Borderline Personality Disorder (BPD) is a disorder which causes emotional instability, such as frequent anger etc.
I once got a friend who suffers BPD and shows abrupt of anger many times without sufficient reason. After reading some materials, I found that there is possible link between BPD and lack of sleep, that is the function of brain in BPD looks similar with people which have lack of sleep. I hypothesize that perhaps the serotonin level in BPD is also affected by lack of sleep.
And recently I found a paper in J. Clin. Sleep Med. 2008 which seems to support the connection between BPD and lack of quality sleep, see http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2576314/.
Does it mean that BPD can be associated with lack of sleep? Does it mean that a person who suffers BPD should increase their sleep time and also get sleep medication? Your comments are welcome.
Here is a researcher who has studied your question:
Chronic sleep disturbances and borderline personality disorder symptoms. Selby, Edward A.. Journal of Consulting and Clinical Psychology 81.5 (Oct 2013): 941-947.
I was of the understanding that poor sleep was more of a symptom of BPD rather than a causal factor. In my limited experience, BPD sufferers at the peak of the symptoms don't feel like they deserve a good night sleep, consequently don't get them. That is from anecdotal and limited experience though
Thank you Barry. Yes, perhaps sleep disorder is symptom of BPD, or may be there is deeper cause here? Best wishes
