When a patient has features of several different types without meeting criteria for any specific personality disorder, a diagnostician may use the category "personality disorder not otherwise specified. Genetic research suggests that a mixture of a genetic diathesis and environmental influences accounts for personality disorders in roughly equal proportions (Cloninger et al. Research geared to identifying single genes that are associated with single personality traits has been frustrating. Complex polygenetic mechanisms with multiple allelic variations seem to be at work (Rutter and Plomin, 1997). While one would expect that biological markers might be linked to genetic factors in personality, the search for clear linkages has proven elusive. Because of space limitations in this chapter, we will summarize what we know about the neurobiology of the three personality disorders that have been most studied: antisocial, borderline, and schizotypal. For each of these conditions, we will review the genetic, epidemiological, and neurobiological research. Although the diagnosis is not applied until a person is 18 years of age, to warrant the diagnosis one must have evidence of conduct disorder with onset before the age of 15. An important epidemiological feature is that the disorder is far more likely to be diagnosed in men than in women. Hence the three studies together offer strong support for a specific interaction between a genotype and traumatic events early in life. Ninety-three families had monozygotic twins, 99 had dizygotic twins, 95 had ordinary siblings, 181 had full siblings in stepfamilies, 110 had half-siblings in stepfamilies, and 130 were characterized by genetically unrelated siblings in stepfamilies. Approximately 60% of the variance in adolescent antisocial behavior could be accounted for by negative and conflictual parental behavior directed specifically at the adolescent. The investigators suggested that certain heritable characteristics of the children evoke harsh and inconsistent parenting. By contrast, siblings without those heritable characteristics did not evoke negative parental behavior, and these siblings seemed to experience a protective effect when harsh parental behavior was directed at the other sibling. It could: (1) enhance desirable features of the child; (2) exacerbate troublesome behavior of the child; (3) lead parents to back off from the difficult child in an attempt to protect the siblings with better prospects; or (4) protect the child from the negative outcomes related to difficult behavior. The term "psychopathy," according to Hare and Harpour (1991), defines a subgroup of antisocial patients with more severe clinical manifestations and more striking resistance to treatment. Approximately 25% of the incarcerated offender populations would qualify as psychopaths (Hare and Harpour, 1991). These patients appear to have substantial neurobiological differences compared with patients who do not meet criteria for psychopathy. They are both more ruthless and more incapable of any type of emotional attachment to others. In addition, a good deal of research has linked the risk of criminal behavior to lowered autonomic nervous system responsiveness (Raine et al. In fact, heightened autonomic nervous system responsiveness appears to be protective against criminal behavior in prospective follow-along studies of teenagers. The brain volume of antisocial subjects may actually be different from that in normal controls. These investigators concluded that this structural deficit may relate to the low autonomic arousal, lack of conscience, and problematic decision-making typical of antisocial and psychopathic individuals. The subjects with psychopathy were characterized by decreased electrodermal responsiveness, the absence of a startle reflex, and less facial expression. The researchers noted that the psychopathic individuals had a pronounced lack of fear in response to events and a general deficit in processing emotional information. They noted that the emotional hyporesponsiveness was highly specific to the individuals with psychopathy. Those with psychopathy had a statistically significant increase in callosal white-matter volume, as well as in callosal length. In addition, they showed a 15% reduction in callosal thickness and an increased functional interhemispheric connectivity. The researchers suggested that atypical neural development processes involving an arrest of early axonal pruning or increased white-matter myelination may be responsible for these corpus callosum abnormalities in psychopathy. The understanding of early environmental factors that influence the expression of genes has the potential to lead to preventive treatment at an early age. Family therapy or individual psychotherapy with parents may lead to alterations in parental behavior that could decrease the likelihood of subsequent antisocial behavior in the children. These individuals can be distinguished from other groups by the overall degree of their multifaceted emotional pain (Stiglmayr et al. Another aspect of their affective disturbance is their tremendous mood reactivity; patients often move from one interpersonally reactive mood state to another, with great rapidity and fluidity, experiencing several dysphoric states and periods of euthymia during the course of one day. In terms of Axis I disorders, major depression, substance misuse, posttraumatic stress disorder, other anxiety disorders, and eating disorders are all common in these individuals (Oldham et al. Various types of adverse event during childhood, including ongoing experiences of neglect and abuse, are reported by many patients (Zanarini et al. The severity of borderline psychopathology has also been linked to severity of childhood sexual abuse (Silk et al. Patients engage in two types: deliberately physically self-destructive, and more general forms of impulsivity. Self-mutilation, suicidal communication, and suicide attempts are the constituent elements of the first type of impulsivity, and common forms of the second are substance abuse, disordered eating, spending sprees, verbal outbursts, and reckless driving. Fourth is intense unstable relationships, which are characterized by two separate but interlocking types of problem. The first is a profound fear of abandonment, which tends to manifest itself in desperate efforts to avoid being left alone.
