Teen borderline personality disorder refers to a mental
condition in which teens manifest impulsive behaviors, intense mood swings,
problems with relationships and possibly tendencies towards self-harm. It is
controversial as to whether teens can really have borderline personality
disorder (BPD), since their personalities are generally not considered to be
fully formed. However, teens with BPD have been the focus of quite a bit of new
research. BPD can look different in teens versus adults, although it has a
similar root cause. It also appears that BPD occurs much more prevalently in
teens than in adults.
