Orbital+Frontal+Personality

THE ORBITAL FRONTAL PERSONALITY

Focal tumors of the orbital regions have also been reported to give rise to gelastic seizures; that is, seizures which induce uncontrolled laughter. In fact, with lesions localized to the orbital frontal lobes patients may become -Disinhibited -Hyperactive -Euphoric -Extroverted -Labile -Overtalkative -Witzelsucht - telling of inappropriate caustic or facetious jokes -Decisions made without regard for consequences -Distractability and develop perseveratory tendencies

It may also be observed -Proneness to criminal behavior -Promiscuity -Gradiosity -Paranoia have also been observed

In general, right orbital damage seems to result in the most severe alterations in mood and emotional functioning, which in turn is likely a function of the greater role of the right frontal lobe and the right hemisphere including the right inferior frontal lobe, in the regulation of emotion and arousal

However, although they may easily swear, laugh, joke, and make threats, they may also become inordinately apathetic and listless, spending much of their time doing nothing.

<span style="color: #000000; font-family: 'Times New Roman',serif;">The term **acquired sociopathy** has been proposed in the context of this syndrome. There is an apparent relationship between the orbitofrontal lobe and antisocial personality disorder and similarities with intermittent explosive disorder and episodic dyscontrol syndrome although these often entail a degree of guilt with tends not to be present in sociopathy. Functional imaging have shown murderers tend to have prefrontal metabolic deficits including the orbitofrontal cortices. It seems injury to the orbitofrontal regions disturb not only the regulation of limbic drives but also their insight in the deficit. In contrast those who have behavior dysregulation on the basis of the interictal syndrome of temperolimbic epilepsy appear to have a preserved, if not excessive, sense of guilt.
