Mild cognitive impairment: A systematic review
2007
MCI is a nosological entity proposed as an intermediate state between normal aging and dementia. The syndrome can be divided into two broad subtypes: amnestic MCI ( aMCI) characterized by reduced memory, and non- amnestic MCI ( naMCI) in which other cognitive functions rather than memory are mostly impaired. aMCI seems to represent an early stage of AD, while the outcomes of the naMCI subtypes appear more heterogeneous - including vascular dementia, frontotemporal dementia or dementia with Lewy bodies- but this aspect is still under debate. MCI in fact represents a condition with multiple sources of heterogeneity, including clinical presentation, etiology, and prognosis. To improve classifi…
Striato-amygdaloid transition area lesions reduce the duration of tonic immobility in the lizard Podarcis hispanica.
2002
Neuroanatomical data suggest that the lizard striato-amygdaloid transition area is homologous with the mammalian central amygdala. In order to investigate possible functional similarities, tonic immobility was induced in adult lizards and its duration recorded. Each lizard was then randomly assigned to one of three treatments: (1) bilateral striato-amygdaloid transition area lesions, (2) bilateral dorsal cortex lesions or (3) untreated controls. Three days after trial 1, each lizard was subjected to a second trial and the tonic immobility duration recorded. The mean tonic immobility duration in lizards with striato-amygdaloid transition area lesions was significantly shorter (80.5%; p < 0.0…
Differences in visual information processing style between Idiopathic Generalized Epilepsy with and without photosensitivity.
2021
Purpose: Recently, altered visual cortical processes i.e., lack of habituation to visual evoked potentials (VEP), has been highlighted in both photosensitive epilepsy and in a specific i.e., analytic mode of processing visual inputs. In this study we aimed at evaluating the relationship between photosensitivity (PS) and analytic style of processing visual information, in a sample of 30 patients with Idiopathic Generalized Epilepsy (IGE) and matched healthy controls. Methods: At our Epilepsy unit of the Sapienza University of Rome, we consecutively enrolled 15 patients with IGE with PSand matched them with 15 patients with IGE without PS and 15 Healthy Volunteers. All patients underwent EEG …
Family-Based Intervention Program for Parents of Substance-Abusing Youth and Adolescents.
2016
Theuse of drugs among adolescents/youth often results in a high degree of distress for the familymembers who live with them. This in turn can lead to a deterioration of mental (psychological) health, hindering any attempt to successfully cope with the situation. The goal of our research was to study the effect of the Community Reinforcement and Family Training (CRAFT) program on parents of adolescents/young adult drug users. Study volunteers (𝑛�� = 50) were parents fromValencia (Spain) that were divided into two groups. The experimental group (𝑛�� = 25) was made up of parents whose sons and daughters exhibited problems with drug use and the constructed noncausal baseline group (𝑛�� = 25)…
Challenging behaviour, and staff responses to it, in residential environments for people with intellectual disability in Finland
2002
The frequency and severity of challenging behaviour in all 261 adult residents of a single special care district in Finland were assessed using the modified version of the Scales of Independent Behavior Problem Behavior Inventory. The results showed that 70% of the residents with intellectual disability exhibited challenging behaviour that was considered to be more than a mild problem by the staff. The incidence of dangerous behaviour was 10%. Some form of negative intervention (restraints, punishment or environmental restrictions) was used for 56% of cases in which challenging behaviour was exhibited. Punishment was the most common consequence for dangerous behaviour. The staff in the smal…
Altered receptor binding densities in experimental antiphospholipid syndrome despite only moderately enhanced autoantibody levels and absence of beha…
2013
Abstract Experimental antiphospholipid syndrome (eAPS) in Balb/c mice causes neuropsychiatric abnormalities including hyperactivity, increased explorative behavior and cognitive deficits. Recently, we have demonstrated that these behavioral changes were linked to an upregulation of serotonergic 5-HT1A receptor binding densities in cortical and hippocampal regions while excitatory and inhibitory neurotransmitter receptors remain largely unchanged. To examine whether the observed behavioral features depend on a critical antibody concentration, mice with only moderately enhanced antiphospholipid antibodies (aPL), about 50–80% of high levels, were analyzed and compared to controls. The staircas…
Computerspielsucht: Ein psychopathologischer Symptomkomplex im Jugendalter
2008
OBJECTIVE Cases of excessive computer gaming are increasingly reported by practitioners in the psychiatric field. Since there is no standardized definition of this symptom complex, the aim of this study is to access excessive computer gaming in German adolescents as an addictive disorder and its potential negative consequences. METHOD Psychopathological computer gaming behavior was diagnosed by applying the adapted diagnostic criteria of substance-related-addictions as defined by the ICD-10. At the same time demographic variables, state of clinical anxiety and underlying cognitive mechanisms were analyzed. RESULTS 6.3 % of the 221 participating pupils - mostly boys with a low educational ba…
P-110 - Gaming addiction - disturbed impulse control in internet addicts and pathological gamblers
2012
Internet Addiction (IA) is proposed to be added as a research diagnosis to the upcoming DSM-V while Pathological Gambling (PG) is proposed to be subsumed under the new section “Addiction and related disorders” as first behavioral addiction. The outpatient clinic for behavioral addiction of the clinic for psychosomatic medicine in Mainz offers counseling and treatment to patients suffering from IA and PG. Deficits in impulse control are suggested to be a key factor to addiction. Studies in PG have shown deficits in the ability to control impulses, for example in decision making, resisting temptation or behavioral inhibition. For Internet addiction previous research on impulse control is spar…
Physical exercise neuroprotects ovariectomized 3xTg-AD mice through BDNF mechanisms.
2014
Postmenopausal women may be more vulnerable to cognitive loss and Alzheimer's disease (AD) than premenopausal women because of their deficiency in estrogens, in addition to their usually older age. Aerobic physical exercise has been proposed as a therapeutic approach for maintaining health and well-being in postmenopausal women, and for improving brain health and plasticity in populations at high risk for AD. To study the neuroprotective mechanisms of physical exercise in a postmenopausal animal model, we submitted previously ovariectomized, six-month old non-transgenic and 3xTg-AD mice to three months of voluntary exercise in a running wheel. At nine months of age, we observed lower grip s…
