Insight in obsessive-compulsive disorder: a study of an Italian sample

Insight is a complex phenomenon that can be interpreted according to a dimensional model. Given the controversial data of insight in obsessive-compulsive disorder (OCD), our study aimed to investigate insight in an Italian sample of patients with OCD by means of the specific item on the Yale-Brown obsessive-compulsive scale (Y-BOCS) and to explore the possible correlations between it and clinical features. One hundred and seventeen out-patients with a DSM-IV diagnosis of OCD and different comorbid psychiatric disorders were included in the study and assessed by means of the Y-BOCS, Hamilton rating scale for depression (HRSD) and the global clinical impression. The results showed that almost 50% of the patients had an excellent level of insight and 15% had a little or no insight. No correlation between levels of insight and clinical features was observed, except for a negative trend with the presence of somatic obsessions. In addition, a trend towards a lower level of insight was observed in those bipolar patients with a positive history of repeated manic or hypomanic episodes. Further studies seem to be necessary in order to establish whether or not OCD patients with poor insight represent a distinct sub-group of patients.     

Kleptomania: clinical features and comorbidity in an Italian sample.

Kleptomania, listed in DSM-IV as an impulse control disorder not elsewhere classified, is a psychiatric condition still poorly understood and subject of only a few systematic studies. The aim of this research was, therefore, to evaluate the clinical features and comorbidity of Italian patients with a DSM-IV diagnosis of kleptomania. Twenty outpatients with a lifetime diagnosis of kleptomania by DSM-IV criteria, were included in the study and underwent a specially designed semistructured interview and the Family History Research Diagnostic Criteria. The majority of patients reported an early and abrupt onset and an episodic course of the disorder, with no gender preponderance. Lifetime comorbidity for other axis I disorders was high, in particular for mood, anxiety, and impulse control disorders. Family history also showed a high prevalence of psychiatric disorders. Our study indicates clear connections between kleptomania and different psychiatric disorders, the exact nature of which has yet to be clarified.     

Rey-Osterrieth complex figure: normative values in an Italian population sample

The Rey-Osterrieth complex figure test (ROCF) is a neuropsychological test extensively used in clinical practice to investigate visuospatial constructional functions, visuographic memory and some aspects of planning and executive function. The aim of the present study was to collect normative values in an Italian normal population sample (n=280) for the direct copying and delayed (10 min) reproduction of the ROCF. Multiple regression analysis revealed significant effects of age and education on performance of both copying tasks, whereas sex appeared to affect only performance on the delayed copying task. Inferential cut-offs have been determined and equivalent scores computed. The availability of equivalent scores for the ROCF will prove useful in clinical assessment since it allows the comparison of a subject's performance on the ROCF with that on other neuropsychological tests for which normative values collected with similar methods are already available for the Italian population.

Mini mental Parkinson test: standardization and normative data on an Italian sample

The mini mental Parkinson (MMP) is a test built to overcome the limits of the mini mental state examination (MMSE) in the short-time screening of cognitive disorders in individuals with Parkinson’s disease (PD). In fact, in this scale, items tapping executive functioning are included to better capture PD-related cognitive changes. Some data sustain the sensitivity and validity of the MMP in the short neuropsychological screening of these individuals. Here, we report normative data on the MMP we collected on a sample of 307 Italian healthy subjects ranging from 40 to 91 years. The results document a detrimental effect of age and an ameliorative effect of education on the MMP total performance score. We provide for correction grids for age and literacy that derive from results of the regression analyses. Moreover, we also computed equivalent scores in order to allow a direct and fast comparison between the performance on the MMP and on other psychometric measures that can be administered to the subjects.     

Prevalence of CT-detected cerebral abnormalities in an elderly Swedish population sample

Objective – To measure the prevalence of computed tomography (CT)‐detected cerebral lesions in a population‐based sample of elderly persons living in Göteborg, Sweden. Methods – Cerebral CT‐scans were performed in the case of 466 women (mean age 74.3 ± 5.1 years) and 191 70‐year‐old men. A single rater assessed white matter lesions (WML) using four different scales, lacunar lesions, large infarcts, cortical atrophy, and basal ganglia calcifications. Results – White matter lesions frequency assessed by different scales ranged between 54.5% and 68.5%. Lacunar lesions were detected in 46.7% (30.1% had lacunes >5 mm) and cerebral infarcts in 3.0% of participants. Overall, 72.8% of participants evidenced cerebral vascular abnormalities. Severe cortical atrophy was more common in temporal (6.4%) and frontal (6.7%) lobes, than in parietal (1.7%) and occipital (1.1%) lobes. Basal ganglia calcifications were found in 38.7% of participants. WML, lacunar lesions, large infarcts, and degree of cortical atrophy correlated positively with age. More lacunes, basal ganglia calcifications, and occipital lobe atrophy were associated with male gender. Conclusions – Vascular and other brain lesions are very common on CT‐scan in an elderly population, but large vascular lesions are rare. This study provides the first reference for the prevalence of CT‐detected abnormalities in an elderly Swedish population.     

Psychological well-being and metacognition in the fourth age: an explorative study in an Italian oldest old sample

Objectives: The research largely aimed at exploring the impact of marital status, cognitive efficiency, gender, physical health and sociocultural context on self-rated emotional competence, depression, memory and cognitive measures.Method: Ninety-four healthy adults aged 75–99 were recruited in the Sardinian province of Ogliastra, where a collectivistic culture prevails, and in northern Italy, which in turn is characterized by the prevalence of individualistic cultural traits. Participants were administered self-referent metacognitive efficiency, subjective wellness and depression measures.Results: Sardinian elders self-rated lower levels of depression and cognitive failures and had greater levels of emotional competence.Conclusions: Perceived psychological well-being, metacognitive efficiency and depression seem to be affected by sociocultural context.     

Self-injury,psychiatric symptoms,and defense mechanisms: Findings in an Italian nonclinical sample

IntroductionThis study provides data on the rates, characteristics, and correlates of self-injury (SI) in an Italian nonclinical sample, a population previously unexamined within the SI literature. This study examined the associations between SI and defense mechanisms, as well as the differences between self-injurers (episodic and recurrent) and non self-injurers with regard to the severity and variety of their psychiatric symptoms and psychological distress.Materials and methodsFive hundred and seventy-eight university students (82.5% female; mean age = 22.3; S.D. = 3.4) were administered a battery of self-report questionnaires, including the “Deliberate Self Harm Inventory” for SI, the Response Evaluation Measure-71 for defense mechanisms, and the “Symptom Checklist-90-Revised” for psychological distress and psychiatric symptoms.ResultsOne hundred and nineteen participants (20.6%) reported having engaged in SI at least once during their lifetime. Individuals with recurrent SI (SI ≥ 5) reported significantly higher levels of all psychiatric symptoms and many maladaptive defense mechanisms than individuals without SI. Results also provided evidence for differences between individuals with recurrent and episodic SI.ConclusionResults suggest that recurrent self-injurers are distinguished from both episodic self-injurers and non self-injurers by their greater use of maladaptive defense mechanisms, rather than their lesser use of adaptive defenses. Further, results suggest that recurrent self-injurers differ from episodic self-injurers not in terms of the severity of their psychiatric symptoms, but the variety and number of these symptoms.     

The Frontal Assessment Battery (FAB): normative values in an Italian population sample

Abstract The Frontal Assessment Battery (FAB) is a short cognitive and behavioural six-subtest battery for the bedside screening of a global executive dysfunction; although recently devised, it is already extensively used thanks to its ease of administration and claimed sensitivity. The aim of the present study was to derive Italian normative values from a sample of 364 control subjects (215 women and 149 men) of different ages (mean: 57.4±17.9 years; range: 20–94 years) and educational level (mean: 10.4±4.3 years.; range: 1–17 years); the Mini Mental State Examination (MMSE) was concurrently administered. Multiple linear regression analysis revealed significant effects for age and education whereas gender was not significant; thus, from the derived linear equation, a correction grid for FAB raw scores was built. Based on nonparametric techniques, inferential cut-off scores were subsequently determined and equivalent scores (ES) computed. Test–restest and interrater reliabilities were both satisfactory. Interestingly, MMSE was significantly correlated with FAB raw scores, whereas adjusted scores were not. The present data may improve the accuracy in the use of the FAB both for clinical and research purposes.     

Epilepsy: an overview

According to Epilepsy Canada (2001), one to two per cent of Canadians have epilepsy and 75 to 80 per cent of these people develop it before the age of 18. Despite the fact that many famous and successful people throughout history have had epilepsy, misunderstanding and prejudice about this common neurological disorder remain prevalent. In our experience, some people diagnosed with epilepsy do not tell others about their medical condition because of their fear of being stigmatized and shunned.     

Mini-Mental State Examination (MMSE): sensitivity in an Italian sample of patients with dementia

The sensitivity of the Mini-Mental State Examination (MMSE) was assessed in a sample of patients with dementia of the Alzheimer type or vascular dementia. The MMSE identified the majority of pts with diffuse cognitive impairment but did not discriminate between the two types of dementia. It failed to detect mild deterioration or forms in which only some cognitive functions were impaired. The test is therefore not sufficient for distinguishing deteriorated from non deteriorated pts, although it is still useful in mass screening or for a quick assessment of deterioration in the course of clinical neurological examination.

---

Sommario Sono state valutate le prestazioni al Mini-Mental State Examination (MMSE) in un campione di soggetti affetti da demenza tipo Alzheimer o da demenza vascolare. Il MMSE individua la maggior parte dei pt. compromessi diffusamente sul piano cognitivo, senza peraltro discriminare fra i due tipi di demenza. Non vengono diagnosticati, invece, deterioramenti di lieve entità o in cui la compromissione è presente solo in alcune funzioni cognitive. Il test non è pertanto sufficiente per distinguere deteriorati da non deteriorati, benchè conservi un'utilità per indagini di massa o per una rapida valutazione del deterioramento durante l'esame neurologico clinico.

     

Epilepsy and EEG paroxysmal abnormalities in autism spectrum disorders

The occurrence of epilepsy in autism is variable; nevertheless, EEG paroxysmal abnormalities (PA) are frequently recorded in patients with autism, although the influence of epilepsy and/or EEG PA on the autistic regression has not been clarified yet. We examine a large sample of 345 inpatients with autism, divided into three groups: (1) patients without epilepsy and EEG PA; (2) patients with EEG PA but no seizures; (3) patients with epilepsy including febrile convulsions. The prevalence of epilepsy (24.9%) and EEG PA (45.5%) was higher than that reported in the general population. The significant differences among the three groups concerned autistic regression (comparison between groups 1 and 2, p < 0.05; comparison between groups 1 and 3, p < 0.01), cerebral lesions (comparison between groups 1 and 2, p < 0.05; between groups 1 and 3, p < 0.001), and symptomatic autism (comparison between groups 1 and 2 as much as comparison between groups 1 and 3, p < 0.001), which were prevalent in groups 2 and 3; while severe/profound mental retardation was more frequent in group 3 compared to group 1 (p < 0.01). Focal epilepsy (43.0%) and febrile convulsions (33.7%) were frequent in the third group with epilepsy. EEG PA were mainly localized in temporal and central areas (31.4%). Only 2.6% of patients had subcontinuous/continuous EEG PA during sleep. Seizures and EEG PA were not related to autistic regression. EEG PA occurred mainly in childhood, while epilepsy tended to occur (p < 0.001) as age increased. The age at onset of seizures had two peaks: between 0 and 5 and between 10 and 15 years with no difference between idiopathic and symptomatic cases. In 58.5% of subjects aged ?20 years, epilepsy including febrile seizures occurred at some point of their lives, while cases with only EEG PA were less frequent (9.7%). The relationship among autism, EEG PA and epilepsy should be clarified and investigated. In autism, seizures and EEG PA could represent an epiphenomenon of a cerebral dysfunction independent of apparent lesions.     

Epilepsy in pervasive developmental disorder without brain MRI abnormalities

Background: Epilepsy has been reported in patients with pervasive developmental disorder (PDD), with an incidence ranging from 5% to 40%; however most of the studies included patients with brain magnetic resonance imaging (MRI) abnormalities (e.g., tuberous sclerosis) and patients with epilepsy whose seizure onset was in the first year of life. Methods: We retrospectively examined 67 patients (45 males, 22 females) with PDD and epilepsy, who did not have brain MRI abnormalities. Patients who had seizures in the first year of life were excluded. We divided the patients into two groups: group A included 34 patients with an IQ < 50, and group B included 33 patients with an IQ ? 50. Results: The median age of epilepsy onset was higher in group A than group B (8.8 vs. 5.2 years, P < 0.01). Only one patient (3%) in group A and nine patients (27%) in group B were classified with generalized epilepsy (P < 0.05). At the last observation, 16 patients (47%) in group A and 25 patients (76%) in group B were seizure-free for ?1 year (not statistically significant). Conclusion: The relationship between PDD and epilepsy may be different between patients with lower (group A) and higher (group B) IQs in patients who do not have brain MRI abnormalities.     

Validation of a screening questionnaire for alcoholism (MAST) in an Italian sample

One hundred fifty subjects (75 index cases and 75 controls) completed the Italian version of the Michigan Alcoholism Screening Test (MAST). Using Relative Operating Characteristic (ROC) analysis, the 5/6 cut-off point was found to be the best as for discriminating between "cases" and "non-cases" in terms of balance between sensitivity (96%) and specificity (89%). The positive predictive value, the negative predictive value, and the overall misclassification rate were 90%, 95%, and 7% respectively. Using item by item assessment of discriminating capacity, we developed a brief ten item Italian version (2/3 cut-off point). This discriminated between alcoholics and non-alcoholics as well as the longer version, and is thus superior in situations where a brief evaluation is necessary.     

Health-related quality of life and depression in an Italian sample of multiple sclerosis patients

Only few publications have been reported on Health-related Quality of Life (HRQoL) in patients with multiple sclerosis (MS). EDSS is the most common outcome measure for either impairment or disability of MS, but it is not able to catch other aspects of MS impact on HRQoL.The authors performed a cross-sectional study on the group of all patients with MS who were diagnosed at least 4 years before 1998 in Catania (South Italy). One hundred and eighty patients out of 308 were enrolled in the study. SF-36 was used to catch the HRQoL of MS patients. EDSS, Beck Depression Inventory (BDI) and time since diagnosis were investigated as variables affecting the HRQoL of MS patients.The patients showed significant lower mean scores for all SF-36 health dimensions compared with sex- and age-adjusted scores in a general healthy Italian population (p<0.001). EDSS scores correlated only with physical functioning (r=-0.76 p<0.001). As expected, the more severe was the disease, the longer its duration and the lower the patients' skillness on HRQoL. BDI showed high partial correlations with all SF-36 health domains with r=-0.38 to -0.65 (p<0.001).This study showed that SF-36 is able to assess the HRQoL of MS patients. Depression strongly influenced the HRQoL of MS patients. EDSS and time since diagnosis also affected the HRQoL of MS patients. Our results are comparable with other European studies.
