Parents Psychopathology of Children with Attention Deficit Hyperactivity Disorder.

Attention Deficit Hyperactivity Disorder (ADHD) is a disorder with extremely complex etiology, not yet well defined but certainly multi-factorial. This study investigated the possible etiopathogenetic role of ADHD symptoms and psychopathology disorders in parents of children with ADHD. We present a case-control study of parents of 50 children affected by ADHD and of 45 healthy children, matched to age and gender. Parents of ADHD children reported higher levels of ADHD symptoms, depressive disorders and Depressive Personality Disorders than parents of healthy children. Mothers displayed greater presence of depression, while fathers showed problems concerning alcohol use. The occurrence of ADHD symptoms, psychopathology and personality disorders in parents highlights the importance to integrate the treatment programs in the ADHD children with the screening and treatment for psychopathological symptoms of the parents.

Tolerability and safety profile of risperidone in a sample of children and adolescents.

The aim of this prospective observational study was to verify the tolerability and safety profile of risperidone in a sample of antipsychotic-naive children/adolescent patients having a different psychiatric diagnosis. Twenty-two (mean age of 12±3.2) antipsychotic-naive patients who started therapy with risperidone were recruited. The assessment involved anthropometric data (weight, height, BMI, BMI z-score and BMI percentile), cardiovascular parameters (blood pressure and QTc interval) and blood tests (levels of glucose, triglycerides, total cholesterol, glutamic oxaloacetic and pyruvic transaminases, &ggr;-glutamyl transferase, prolactin, free triiodothyronine, free thyroxine, thyroid-stimulating hormone, thyroglobulin, antithyroid peroxidase and antithyroglobulin). After an average follow-up of 6 months of risperidone therapy, a statistically significant increase in weight and body composition was observed. Furthermore, an increase in serum levels of prolactin was observed in 50% of patients. No other significant changes in metabolic and cardiovascular parameters were found. Although an increase in these parameters was detected, it remained in the normal range. This study suggests the use of specific protocols for monitoring children/adolescents treated with second-generation antipsychotics to manage the metabolic long-term complications and progression to more severe disease states.

Psychopathology in children and adolescents with primary headaches: categorical and dimensional approaches.

Background Recurrent headache is common in childhood, but there is not a great amount of data on the associations between headaches and psychopathology in children. Objective The aim of this study is to examine the relationships between primary headaches and psychopathology in children, using both the categorical and dimensional assessment. Methods The sample consisted of 70 patients with primary headache compared to a matched sample of 50 healthy children. Psychiatric comorbidity was defined according to the diagnostic criteria of the Diagnostic and Statistical Manual of Disorders. Child psychopathology outcomes were assessed using child- and parent-reported standardized instruments. Results Internalizing and externalizing problems were significantly represented among children with headaches compared to the control group, respectively 63% and 27%, without significant differences between migraine and tension-type headache children. Moreover, a total of 26% of the children with a headache reported psychiatric comorbidity such as anxiety and mood disorders. Conclusion The dimensional approach improves accuracy in the recognition of emotional and behavioral problems compared to the categorical approach; however, the use of both of these approaches could be useful for clinical practice, treatment and research.

Familial liability, obstetric complications and childhood development abnormalities in early onset schizophrenia: a case control study

BackgroundGenetic and environmental risk factors and gene-environment interactions are linked to higher likelihood of developing schizophrenia in accordance with the neurodevelopmental model of disease; little is known about risk factors and early development in early-onset schizophrenia (EOS) and very early-onset schizophrenia (VEOS).MethodsWe present a case-control study of a sample of 21 patients with EOS/VEOS and a control group of 21 patients with migraine, recruited from the Child Neuropsychiatry Unit, Department of Neurologic and Psychiatric Science, University of Bari, Italy. The aim was to assess the statistical association between VEOS/EOS and family history for psychiatric disorders, obstetric complications and childhood developmental abnormalities using 2 × 2 tables and a Chi Squared or Fisher test.ResultsThe results show a statistical association between EOS/VEOS and schizophrenia and related disorders (P = 0.02) and personality disorders (P = 0.003) in relatives, and between EOS/VEOS and developmental abnormalities of early relational skills (P = 0.008) and learning (P = 0.04); there is not a statistically relevant difference between cases and controls (P > 0.05) for any obstetric complications (pre, peri and postpartum).ConclusionsThis study confirms the significant role of familial liability but not of obstetric complications in the pathogenesis of VEOS/EOS; the association between childhood developmental abnormalities and EOS/VEOS supports the neurodevelopmental model of disease.

Prolactin variations during risperidone therapy in a sample of drug-naive children and adolescents

The aim of this prospective observational study was to investigate the variations of serum prolactin hormone (PRL) in a sample of 34 drug-naive patients (mean age 13 years) who started risperidone therapy assuming that several factors may favor the increase in serum PRL. Serum PRL and hyperprolactinemia clinical signs were examined at baseline (T0) and after almost 3 months of treatment (T1). We considered sex, pubertal status, risperidone dosage, psychiatric diagnosis, and any personal/family history of autoimmune diseases. The mean serum PRL value increased between T0 and T1 (P=0.004). The mean serum PRL was higher in females in the pubertal/postpubertal stage and for risperidone dosage up 1 mg/day. Hyperprolactinemia was found in 20% of patients at T0 and in 38% of patients at T1 (P=0.03). The mean serum PRL increase was greater in early-onset schizophrenia spectrum psychosis patients compared with no-early-onset schizophrenia spectrum psychosis patients (P=0.04). The increase in PRL was higher in patients with a personal and a family history of autoimmune diseases. This study suggests that the increase in serum PRL in patients treated with risperidone may be linked not only to the drug and its dosage but also to several risk factors such as sex, pubertal stage, psychiatric disease, and autoimmune disorders.

Anti-brain autoantibodies in the serum of schizophrenic patients: A case-control study

Schizophrenia is considered a neurodevelopmental disorder with a multifactorial pathogenesis where autoimmune factors may play a significant role. The aim of this study was to verify the presence of anti-brain autoantibodies in the serum of schizophrenic patients compared to healthy controls. Autoantibodies against brain were detected by the immunofluorescence method, utilizing sections of rat hippocampus and hypothalamus and of monkey cerebellum. Three different fluorescence patterns were observed, staining the nucleus-cytoplasm of neurons, the neuroendothelial of blood vessel and the neurofilaments. Search for other organ-specific and non organ-specific autoantibodies was performed in all sera by indirect immunofluorescence method, enzyme linked immunosorbent assay and chemiluminescence immunoassay. Results showed a significant association between schizophrenia and anti-brain autoantibodies against the neuroendothelium of blood vessel in hypothalamus, hippocampus and cerebellum; a significant nuclear and cytoplasmic staining of neurons was assessed only for the hippocampus. No other significant association was found, except between schizophrenia and anti-nuclear autoantibodies on HEp-2 cells. In conclusion, these results support the hypothesis of a significant association between schizophrenia and circulating anti-brain autoantibodies, suggesting a diffuse reactivity against the neuroendothelium of blood vessel and highlighting a nuclear and cytoplasmic staining of the neurons of hippocampus.

Aggressive behavior, cognitive impairment, and depressive symptoms in elderly subjects

Patients with dementia often have neuropsychiatric symptoms. The objective of this study was to evaluate the relationship between neuropsychiatric symptoms and progressive cognitive decline by assessing cognitive impairment, depressive symptoms, and aggressive behavior in a sample of elderly subjects. The study sample consisted of 201 subjects admitted to nursing homes. For the purpose of the present study each subject was evaluated using the Mini-Mental State Examination, the Geriatric Depression Scale, and the Modified Overt Aggression Scale. The results show that aggressive behavior and depressive symptoms are associated with progressive cognitive decline in elderly subjects. Early assessment of these conditions can promote rational therapeutic strategies that may improve the quality of life and delay institutionalization for elderly patients.

Circulating anti-brain autoantibodies in schizophrenia and mood disorders

In recent years, an inflammatory autoimmune process, autoantibodies mediated, has been porposed as having a role in the development of different psychiatric disorders. The aim of this study was to assay organ-specific and non organ-specific circulating autoantibodies in schizophrenia, mood disorders and healthy controls; among organ-specific autoantibodies we focused on different fluorescence patterns of anti-brain autoantibodies against rat and monkeys sections of hippocampus, hypothalamus and cerebellum. Serum samples from 50 acutelly ill patients (30 schizophrenia and 20 mood disorders) and from 20 healthy controls were collected. Autoantibodies were assayed by indirect immunofluorescence, enzyme linked immunosorbent assay and chemiluminescence immunoassay. We found a significant difference for circulating autoantibodies to hypothalamus, hippocampus and cerebellum and for anti-nuclear autoantibodies in both schizophrenia and mood disorders when compared to the control group. Referring to the two groups of patients only, circulating antibodies anti-hypothalamus were found significant higher in mood disorders rather than in schizophrenia, with specific regard to nuclear and cytoplasmic staining of the neurons. These data suggest an aspecific diffuse brain involvement of anti-brain autoantibodies in acute phases of schizophrenia and mood disorders. The greater involvement of the hypothalamus in mood disorders highlights the close relationship between autoimmunity, hypothalamic-pituitary-adrenal axis and affective disorders.

Ophthalmoplegic migraine: Migraine or oculomotor neuropathy?

Background Ophthalmoplegic migraine (OM) is a rare condition characterized by the association of headaches and an oculomotor nerve palsy. The third cranial nerve is commonly involved in recurrent attacks, whereas involvement of the sixth and fourth nerves is uncommon. It is still debated whether an uncontrolled migraine or an oculomotor neuropathy may be the primary cause of ophthalmoplegic migraine. Cases We report two patients affected by OM with normal magnetic resonance imaging findings and a history of uncontrolled migraine before an attack of OM. Conclusion The cases reported allow us to hypothesize that OM may be considered a form of migraine rather than a cranial neuralgia. It is possible that different factors such as inflammatory or structural factors, may represent a vulnerability of the nerve during a severe migraine attack causing ophthalmoplegia.

Antibasal Ganglia Antibodies and Antistreptolysin O in Noncomorbid ADHD

Objective: An association between streptococcal infections, ABGA positivity, and no comorbidity ADHD (nc-ADHD) has been little investigated. The aim of this study was to evaluate the streptococcal infection frequency, defined entitled serum antistreptolysin O (ASO), and frequency of serum ABGA positivity in a sample of patients with nc-ADHD. Method: In all 40 participants were investigated the ASO titer and ABGA. Results: The results showed that ABGA positivity was statistically significantly higher in patients affected by ADHD than in patients of a control group, and pathological values of ASO were statistically more frequent in the ADHD group than the control group. Conclusion: These data suggest that streptococcal infections and autoimmune reactions against the basal ganglia are more frequent in ADHD patients than patients in a control group.
