“…In schizotypal personality disorder, an alteration in dopaminergic function is suggested while disturbance in serotonergic activity is suggested in subjects with borderline personality and antisocial personality disorders [27,43,44]. The observation of different clusters of personality disorders in psychotic Saudi patients irrespective amphetamine-related or not coincides with literature data of expected personality disorders in psychotic patients whether they were schizophrenic or non-schizophrenic [45,46]. Although the psychotic condition of many patients had stabilized before assessment of personality disorders, the significant high incidence of cluster B personality disorder especially antisocial personality in amphetamine positive psychotic patients (37%) raises the question of whether cluster B disorder observed is just related to the psychotic element or an extension to the acute amphetamine use.…”

“…It is often assumed that negative symptoms are abnormal conditions, but normative studies have not been conducted. In addition, negative symptoms are very close to the specific criteria for a number of personality disorders (i.e., Schizoid, Avoidant and Schizotypal personality disorders) 4,5 .…”

Premorbid Negative Symptoms in First-Episode Psychosis

Background and Objectives: Negative symptoms emerge in many patients with psychotic disorders long before the onset of the acute illness. These symptoms are often impossible to differentiate from certain Cluster A personality traits. Methods: The current study examines the extent to which premorbid negative symptoms are contributing factors to the development of primary and secondary negative symptomatology. Participants were 84 neuroleptic-naïve patients experiencing the occurrence of their first acute psychotic episode. Symptoms of psychopathology were assessed at two points: at admission and after remission of the acute episode. The Spanish version of the PANSS scale was administered. Premorbid personality assessment was considered as a proxy measure to evaluate each participant's negative symptomatology prior to the onset of the illness. Potential causes of secondary negative symptomatology, such as depression and extrapyramidal symptoms, were also examined. Results: 'Non-respondent' or 'residual' negative symptoms at discharge were significantly predicted by primary negative symptoms. To a lesser extent, disorganization and depressive symptoms at discharge and the Schizoid dimension of premorbid personality predicted residual negative symptoms. Conclusions: The severity of negative symptoms at the onset of the psychotic episode varied across patients. After controlling for 'respondent' and 'non-respondent' primary negative symptoms and other potential causes of negative symptoms, premorbid negative symptoms had a slight, but significant predictive relationship with residual negative symptoms.

“…Another reason for the discrepancy might be that schizophrenia overlaps with various personality disorders [24,25], and the personality types incidentally included might also be different. Although personality disorder functioning styles have been studied less in schizophrenia, a reduced openness to experiences including feelings, values and actions [26], more hypochondriasis and hysteria [27], and more harm avoidance [28] have been reported for this disorder.…”

Objectives: Personality disorder functioning styles might contribute to the inconclusive findings about alexithymic features in schizophrenia. We therefore studied the relationship between alexithymia and personality styles in paranoid schizophrenia. Methods: We administered the Chinese versions of the Toronto Alexithymia Scale (TAS-20), the Parker Personality Measure (PERM), the Positive and Negative Syndrome Scale as well as the Hamilton Anxiety and Depression Scales to 60 paranoid schizophrenia patients and 60 healthy control subjects. Results: Patients scored significantly higher on the Positive and Negative Syndrome Scale, TAS ‘difficulty identifying feelings’ and ‘difficulty describing feelings’, Hamilton Depression Scale and most PERM scales. In healthy subjects, difficulty identifying feelings predicted the PERM ‘dependent’ style, and the Hamilton Anxiety Scale predicted difficulty identifying feelings and difficulty describing feelings. In patients, difficulty identifying feelings nonspecifically predicted all the PERM scales; by contrast, the PERM ‘antisocial’ style predicted difficulty identifying feelings, the ‘avoidant’ style predicted difficulty describing feelings, and the ‘histrionic’ and ‘paranoid (–)’ styles predicted ‘externally oriented thinking’. Conclusions: Personality disorder functioning styles – instead of anxiety, depression, psychotic symptoms or disease duration – were specifically associated with alexithymia scales in our patients, which sheds light on a cognitive-personological substrate in paranoid schizophrenia on the one hand, and calls for a longitudinal design to discover how premorbid or postacute residual personality styles contribute to the sluggish disorder on the other.
