These issues do not sound like BPD to me. I didn’t know it, but I actually suffered from it myself for most of my adolescence, and didn’t receive a medical diagnosis until very recently. I also was diagnosed with major depressive disorder, ADHD and anxiety/panic disorders a while ago, but I’ve been taking medications for them and don’t suffer from my previous BPD symptoms (although I do have problems with disassociating now). BPD is very widely misunderstood, and there are many possible symptoms of it, and even with the common symptoms seen in social interactions and perceptions by those with the disorder, each individual is unique in the way that BPD manifests in their lives and behavior. The easiest way to tell signs of it in others is in the way they interact with others.
The symptoms you’ve described are more apparently behavioral patterns indicating a mental disorder, rather than a personality disorder, as they don’t seem to be affected by external stimuli or social/intimate interactions.
To me, (and I’m not at all a psychiatric professional, I just have a lot of personal familiarity with mental disorders and have studied psychology) these symptoms almost appear to be possibly Schizophrenic. Those with Schizophrenia often suffer from memory loss (aka forgetfulness), paranoia (they believe that others are always out to harm them and often believe supernatural forces are used against them, like black magic), narcissism (they believe they are special or have inhuman powers/capabilities or that have been “chosen” by a higher power for something important, or are better than everyone else for some reason), violent mood swings (often random and not seemingly caused by anything, with manic episodes involving some of the things you mentioned, like the shaking and crying etc).
If he has suffered other psychiatric disorders then he may be at risk for developing Schizophrenia, as it is more common in males than females, and most often doesn’t develop until later in life, often symptoms begin showing between ages 16 and 30. It seems as though he may be showing signs of early developing dilusional behaviors.
You should contact his psychiatrist and speak with him privately about these issues, as they could be indicators of something more serious, and if it is Schizophrenia, the best hope of catching it before it becomes a seriously debilitating disorder is as early as possible.
Like I said, I’m no professional, but I do know that it’s important to speak with one as soon as possible. Even if it’s something completely different, these symptoms and behavior definitely seem troublesome and potentionally serious, and should be addressed now so he can receive the proper psychiatric care for his wellbeing and for the safety and wellbeing of those around him
I don't know, kinda sounds like some of the symptoms, but thie information you have provided could have a number of causes. Bipolar and ADD have some of the symptoms you describe. Any drug or alcohol abuse? Does he do any sort of self mutilation...even severe nail biting or finger picking? Do a little more research if you want, but definitely get him in to see someone who specializes in mood disorders or a psychiatrist. Think of this though....if you are spending a lot time trying to diagnose him and he doesn't feel there is a problem, you should consider your personal options. Good luck!
I would say no honestly.. I looked up on Wikipedia what the official symptoms are and they are as follows:
Unstable interpersonal relationships, affective distress, marked impulsivity, and unstable self-image are the primary features of BPD.
Individuals with BPD tend to experience frequent, strong and long-lasting states of aversive tension, often triggered by perceived rejection, being alone or perceived failure.They may show lability (changeability) between anger and anxiety or between depression and anxiety and temperamental sensitivity to emotive stimuli.
The negative emotional states specific to BPD fall into four categories: destructive or self-destructive feelings; extreme feelings in general; feelings of fragmentation or lack of identity; and feelings of victimization.[8]
Individuals with BPD can be very sensitive to the way others treat them, reacting strongly to perceived criticism or hurtfulness. Their feelings about others often shift from positive to negative, generally after a disappointment or perceived threat of losing someone. Self-image can also change rapidly from extremely positive to extremely negative. Impulsive behaviors are common, including alcohol or drug abuse, promiscuous and intense sexuality, gambling and recklessness in general Attachment studies have revealed a strong association between BPD and insecure attachment style, the most characteristic types being "unresolved", "preoccupied", and "fearful". Evidence suggests that individuals with BPD, while being high in intimacy- or novelty-seeking, can be hyper-alert to signs of rejection or devaluation and tend toward insecure, avoidant or ambivalent, or fearfully preoccupied patterns in relationships.They tend to view the world as generally dangerous and malevolent.
Some mental health professionalsdescribe individuals with BPD as deliberately manipulative or difficult, but analysis and findings generally trace behaviors to inner pain and turmoil, powerlessness and defensive reactions, or limited coping and communication skills.
Suicidal or self-harming behavior is one of the core diagnostic criteria in with a BPD diagnosis.
I don't know the person you're inquiring about and am no doctor but I do have BPD and from what you described, doesn't really sound like he fits. I would of course suggest a meetting with a doctor of course. Luck to you.
