They also do not have delusions.</p><p>People with SPD may be very disturbed. They may also have unusual preoccupations and fears, such as fear of being monitored by government agencies.</p><p>More commonly, people with this disorder behave oddly and have unusual beliefs (such as aliens). They cling to these beliefs so strongly that they have difficulty forming and keeping close relationships.</p><p>People with SPD may also have depression. A second personality disorder, such as <a test="test" href="./000935.htm">borderline personality disorder</a>, is also common.
