The only common symptom I can see that is found in both borderline personality disorder and ME/CFS is
emotional lability (also called emotional instability, or the pseudobulbar affect).
So given this dissimilarity (ie, that there are so few symptoms in common), you probably would not expect to find much comorbidity between BPS and ME/CFS.
Here are the symptoms of BPD:
Specific Symptoms of Borderline Personality Disorder
A person with this disorder will also often exhibit impulsive behaviors and have a majority of the following symptoms:
- Frantic efforts to avoid real or imagined abandonment
- A pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation
- Identity disturbance, such as a significant and persistent unstable self-image or sense of self
- Impulsivity in at least two areas that are potentially self-damaging (e.g., spending, sex, substance abuse, reckless driving, binge eating)
- Recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior
- Emotional instability due to significant reactivity of mood (e.g., intense episodic dysphoria, irritability, oranxiety usually lasting a few hours and only rarely more than a few days)
- Chronic feelings of emptiness
- Inappropriate, intense anger or difficulty controlling anger (e.g., frequent displays of temper, constant anger, recurrent physical fights)
- Transient, stress-related paranoid thoughts or severe dissociative symptoms
I think may of slightly changed the diagnostic criteria since I was given a wrong diagnoses of this. I may be wrong but I thought was previously - fear of abandonment being part of the diagnostic criteria.
In fact many of the questions they ask a ME person and the answers a ME person may give.. may end up leading to a BPD diagnoses not just on the grounds of emotional instability being in both illnesses.
eg I got asked "Do you feel abandoned?" and as I dont have much support for severe ME I said yes to this. I have been abandoned by some family members. So that got me a tick on their diagnostic criteria checklist for BPD
I was seeing that psych due to trying to suicide (around the ME issues).. so that got me another tick on their diagnostic criteria for BPD checklist (cause I'd tried to suicide more then once)
I had emotional instability due to my other health issues including I do when I eat wrongly and get negatively affected by foods or if Im very crashed with my ME i get emotional instability too.. so that gave me another tick on their BPD checklist.
as ME had taken so much away from me and I feel like Ive lost the person I was (of cause like most of us I had to leave my job, had to leave my studies and so much else). They probably gave me a tick in the BPD indentity crisis area too.
I had gone impulsive when I became suicidal.. so did do once do some reckless driving while wishing I was dead and not then caring if I lived or died. So I also got a tick in that area. (Im usually not at all impulsive though unless Im having a major emotional crisis at the time and hence had had a emotional breakdown.. but anyway, they gave me a tick for that area too). oh I was impulsive if I ate wrong and caused a mood swing due to an hyperinsulinemia spike but they didnt care that it was caused by other medical conditon.
They asked about my relationships with family.. something which I gave some negative responses too just to how some of my family have been around the ME.. so I suppose they also give me a tick for interpersonal relationship issues.
"Inappropriate, intense anger "
and a ME patient storming out of a drs surgery after being told to just push harder and exercise. You could score point towards BPD diagnostic criteria as a psych view that response as being unreasonable so now you get put down as having inappropiate anger.. another point towards getting a BPD diagnoses then.
We see a lot of anger among the ME community over the ME/CFS situation in which many who do not understand this, will view as emotionally inappropriate.
In the previous diagnostic stuff, they used to look for black and white thinking and I do have that (but I had that due to Aspergers which they had missed at the time).
So in my case I ended up with a wrong BPD diagnoses due to the questions they asked and my replies,
they didnt care if the abandonment thing was true. They didnt care that one was really in true need of family support etc. They didnt consider if the person was going through anything else major which could lead to a person feeling or being suicidal. I personally believe that a high number of "severe" ME patients feel suicial at times and I guess many have tried to suicide at some point with severe ME due too too much pain or the situation of being completely housebound or bedridden.
i personally that many with ME who do not have BPD at all may be ending up with this diagnoses added to the list of diagnoses they have.
