A cohort of 199 individuals with mental retardation referred for behavioral and psychiatric crisis intervention services was studied to determine attributes differentiating physically aggressive behavior from other behavioral problems. Individuals with aggressive and nonaggressive behavior had similar neurological histories and current medical status and similar levels of seizure disorders and CNS abnormalities. Aggressive individuals more often had psychiatric diagnoses of organic brain syndrome, but frequencies of this diagnosis in each group were small. Current aggression was predicted by gender, level of mental retardation, and history of previous institutional placement; the strongest predictor was history of aggression. These data suggest a complex equation to describe social inadequacy involving interactions between CNS functioning and developmental cognitive and social variables that are only partially defined at this time. Further work to characterize this interaction almost certainly must include a prospective longitudinal analysis of social and developmental functions early in life.

Magnetic resonance imaging (MRI) of the brain is a sensitive method to detect parenchymal tissue lesions. Its value in the diagnosis of central nervous system (CNS) lupus is disputed. To address this question, we have conducted an open and prospective study in a population of 44 SLE patients. We investigated 24 patients (mean age 33 +/- 13 yr) with past or active CNS lupus (group A) that included organic brain syndrome (12), migraine (8), focal neurological signs (7), seizures (2), myelopathy (1) and narcolepsy-cataplexy (1), and 20 patients (mean age 32 +/- 12 yr) without CNS lupus (group B). Health controls comprising nine females and one male aged 31 +/- 9 yr were also studied for comparison (group C). MRI was performed using sagittal T1-weighted images, axial and coronal spin density, and T2-weighted images. All scans were read blindly. Thirteen patients in group A and 10 in group B had well-identified lesions on sequences with long repetition time. Lesions were mostly multiple, small, punctate areas of increased signal at periventricular or subcortical white matter of both cerebral hemispheres. The number and location of lesions were not significantly different in both groups. None of the group C patients had MRI lesions. The presence of lesions was significantly associated with age at study and disease duration, but not with the presence of CNS lupus. In summary, MRI abnormalities are detected in neurologically asymptomatic SLE patients. Whether this represents subclinical brain involvement remains unknown.

Five patients with chronic psychosis and episodic aggressive dyscontrol were treated with electroconvulsive therapy (ECT). Four patients also demonstrated clinical evidence of seizure disorder. ECT resulted in marked reduction of both episodic aggressive dyscontrol and clinical seizures, with modest improvement of psychosis. No patient developed clinical signs of organic brain syndrome during ECT. Albeit in a small number of patients, our findings indicate that ECT may have short-term therapeutic effects on episodic aggressive dyscontrol in patients with chronic psychoses.

Neuropsychiatric systemic lupus erythematosus (NPSLE) has become a popular term designing all neurological and psychiatric complications in patients with systemic lupus erythematosus (SLE). It occurs in up to two thirds of all SLE patients and it covers a vast array of disorders ranging from peripheral neuropathy to stroke, psychosis, and dementia. Mechanisms associated with the pathogenesis of NPSLE include anti-neuronal antibodies, antiphospholipid antibody associated thrombosis, emboli from cardiac source and, rarely, vasculitis by immune complex depositions. Although the most common manifestations is cognitive dysfunction (50%), NPSLE may also present itself as peripheral neuropathy (15%), psychosis (10%), or other central nervous system abnormalities (stroke, organic brain syndrome, seizures). In lupus patients, one should always look for secondary causes of the neuropsychiatric manifestation, including infection, toxic metabolic abnormalities, and hypertension. We present two cases of SLE, which developed neuropsychiatric manifestations.

The aim of this study is to determine S100B protein levels in serum and cerebrospinal fluid (CSF) in patients with different forms of neruopsychiatric systemic lupus erythematosus (NPSLE). There were 157 SLE patients (65 with and 92 without NPSLE, and 20 patients without rheumatic diseases served as controls) recruited in the present study. Serum and CSF S100B protein levels were measured by ELISA assay. Serum S100B protein levels in patients with NPSLE (0.179 +/- 0.095 microg/l) were significantly higher than the levels in patients without NPSLE (0.110 +/- 0.091 microg/l; p < 0.001) and in controls (0.103 +/- 0.065 microg/l; p = 0.005). Thus, the differences in serum levels between non-NPSLE patients and controls had no statistical significance. The serum and CSF S100B protein contents in patients with organic brain syndrome, seizures, cerebral vascular accident, and psychosis were significantly higher than those in controls (all p < 0.001). However, there was no significant difference in serum and CSF S100B protein levels among patients with headache, patients with neuropathy, and controls. In conclusion, serum and CSF S100B levels were raised in NPSLE, especially concerning patients with organic brain syndrome, seizures, cerebral vascular accident, and psychosis. The results obtained imply that S100B protein is possibly an available and complementary biochemical marker within evaluation of NPSLE and deserves further study.

Acute intermittent porphyria (AIP) is a metabolic disease characterized by recurrent attacks of neurological and psychiatric dysfunction. It is a rare disorder of heme metabolism that usually presents with abdominal pain, gastrointestinal symptoms and autonomic nervous system disturbances. Exposure to certain drugs, dieting, starvation and infection during pregnancy may precipitate AIP attacks. Psychiatric manifestations of AIP include mood changes, organic brain syndrome and psychosis. Here, we present a 21-year-old female patient with AIP and major depression. She had a caesarean section under general anesthesia with pentothal and her recovery time from anesthesia took longer than usual. She had a blood transfusion because of severe anemia following the operation. Three days after her discharge she was readmitted to the hospital with confusion and seizure. It was her first AIP attack and it started 6 days after caesarean section. Two months after her first attack, we saw her for anxiety and depressive symptoms. She was in severe anxiety and depression and she was put on fluoxetine (20 mg/day liquid form). Following the treatment she did not develop any other porphyria attack. Her symptoms vanished and she improved functionally. She stayed on fluoxetine for 6 months without any new AIP attack. Despite limited data regarding fluoxetine therapy in porphyria patients, it seems to be safe for the treatment of depressive and anxiety symptoms in these patients.
