BACKGROUND
Fratricide is the killing of one's own bother. It's a type of homicide rarely seen on psychiatric practice. This is still a theme which is poorly studied, and not well understood by the scientific literature.
OBJECTIVE
To report a case of a men, with paranoid schizophrenia that murdered his own bother and had a psychiatric forensic evaluation to establish his penal responsibility.
METHODS
A psychiatric interview was carried out and the psychiatric diagnosis was established based on the interview and analysis of forensic and medical records, using the DSM-IV-TR criteria. Literature review was held about the theme.
RESULTS
The examinee was considered not guilty by reason of insanity, due to the presence of a mental disorder that affected her entire understanding and volition of the practiced act.
CONCLUSIONS
The study of such cases may illustrate and identify motivating factors related to homicidal behavior in individuals with severe mental disorders.

Most paranoid patients have traditionally been diagnosed as schizophrenic, although considerable evidence points to the dissimilarities between paranoid and nonparanoid schizophrenic patients and to commonalities between paranoid and affective disorder groups. Based on a review of research, it is suggested that paranoid schizophrenia, at least in some of its varieties, may more fruitfully be conceptualized as a phenotypic expression of an underlying depressive mode than as a schizophrenic form. This formulation is presented within the framework of a broad examination of diagnostic issues.

The aim of this study was to search for correlates of cognitive impairment in patients with paranoid schizophrenia among clinical, demographic, anamnestic and biochemical markers (NSE, S100B protein, BDNF, hs-CRP). Patients with paranoid schizophrenia (n=125) were examined using the Brief Assessment of Cognitive Function in Schizophrenia, the Rey-Osterrieth Complex Figure task, and a number of clinical scales including the Positive and Negative Syndrome Scale. The majority of patients demonstrated cognitive impairment. The type of impairment was highly heterogeneous and individual. Relationships were found between the degree of executive functioning and family history of mental illness; working memory and age of onset of schizophrenia; and visual memory and psychopathological symptomatology. Negative and affective symptoms were not significantly associated with cognitive functioning. Treatment with first generation antipsychotics was associated with a more frequent impairment of motor skills, and concomitant anticholinergic drugs, with reduced accuracy. Use of second-generation antipsychotics only was associated with better accuracy, working memory and speech fluency. Among the patients, 21.4% had signs of a systemic inflammatory response, indicating a possible role of inflammatory response in the development of schizophrenia. CRP, S100B and NSE levels reflected features of the course of illness and therapeutic response. Patients with lower concentrations of BDNF were characterized by lower processing speeds.

Previous investigations of the influence of paranoia on facial affect recognition in schizophrenia have been inconclusive as some studies demonstrate better performance for paranoid relative to non-paranoid patients and others show that paranoid patients display greater impairments. These studies have been limited by small sample sizes and inconsistencies in the criteria used to define groups. Here, we utilized an established emotion recognition task and a large sample to examine differential performance in emotion recognition ability between patients who were actively paranoid (AP) and those who were not actively paranoid (NAP). Accuracy and error patterns on the Penn Emotion Recognition test (ER40) were examined in 132 patients (64 NAP and 68 AP). Groups were defined based on the presence of paranoid ideation at the time of testing rather than diagnostic subtype. AP and NAP patients did not differ in overall task accuracy; however, an emotion by group interaction indicated that AP patients were significantly worse than NAP patients at correctly labeling neutral faces. A comparison of error patterns on neutral stimuli revealed that the groups differed only in misattributions of anger expressions, with AP patients being significantly more likely to misidentify a neutral expression as angry. The present findings suggest that paranoia is associated with a tendency to over attribute threat to ambiguous stimuli and also lend support to emerging hypotheses of amygdala hyperactivation as a potential neural mechanism for paranoid ideation.

During stages of remission, patients with paranoid schizophrenia seldom show severe attentional or information-processing dysfunctions, except in cases of long-term chronicity. The diagnostic specificity of four putative psychological vulnerability indicators of schizophrenia - the Span of Apprehension, the degraded stimulus Continuous Performance Test (dsCPT), the degraded stimulus visual backward masking task and the Wisconsin Card Sorting Test (WCST) - was examined in a group of patients with paranoid schizophrenia. Since no single test seems to identify all patients, the use of a combination of measures may be a useful strategy. Accordingly, the four tests were administered to 18 paranoid schizophrenic patients, 18 depressed patients and 18 normal subjects. Paranoid schizophrenic patients could be distinguished from normal subjects primarily on the basis of their performance on the backward masking task and secondarily by the dsCPT and the WCST. Paranoid schizophrenic and depressed patients could be differentiated to some extent by their performance on an information-mask condition of the backward masking task. Thus, of the four measures studied, only the degraded stimulus backward masking appeared to be a specific indicator of paranoid schizophrenia.

Epidemiological data available on paranoid schizophrenia are noteworthy for their paucity and poor quality. Although it is commonly said that the paranoid subtype is less common in developing countries, published studies are contradictory. It has also been said that paranoid schizophrenia occurs more frequently among educated persons, but the evidence is not conclusive. Two Scandinavian studies suggest that the paranoid subtype increased in frequency during this century. Assertions that some cultures produce large numbers of paranoid persons are of great interest since schizophrenic symptomatology is partly dependent on culture. The most famous such culture, the Dobuans, are found to be a product of ethnographic bias and probably do not exist as described. This leaves the question of cultural influence on paranoid schizophrenia wide open. Two studies on the seasonality of paranoid schizophrenic births found that their birth pattern does not differ from the seasonal pattern previously established for schizophrenic births as a whole. It is concluded that the epidemiology of paranoid schizophrenia is an area of potentially fruitful inquiry and one that is mostly terra incognita.
