Problematic internet use: Proposed classification and diagnostic criteria

DEPRESSION AND ANXIETY, Issue 4 2003
Nathan A. Shapira M.D., Ph.D.
Abstract Since the mid-1990s, there have been frequent reports of individuals whose use of the computer and internet is problematic. Given the recent expansion and the expected increase in internet availability and usage in the coming years, it is important that healthcare professionals be informed about this behavior and its associated problems. Recently, psychological and psychiatric literature has described individuals that exhibit problematic internet use who often suffer from other psychiatric disorders. In the face of this comorbidity, it is essential to evaluate whether these individuals represent a distinct class of disorder, or a manifestation/coping mechanism related to other underlying diagnosis. In either event, problematic internet use negatively impacts social and emotional functioning. Based on the current limited empirical evidence, problematic internet use may best be classified as an impulse control disorder. It is therefore imperative that problematic internet use be appropriately identified among symptomatic individuals. For these reasons, we propose specific diagnostic criteria that will allow for consistent identification and assist in further study of this behavior.

The dimensionality of alcohol use disorders and alcohol consumption in a cross-national perspective

ADDICTION, Issue 2 2010
Guilherme Borges
ABSTRACT Aims To replicate the finding that there is a single dimension trait in alcohol use disorders and to test whether the usual 5+ drinks for men and 4+ drinks for women and other measures of alcohol consumption help to improve alcohol use disorder criteria in a series of diverse patients from emergency departments (EDs) in four countries. Design Cross-sectional surveys of patients aged 18 years and older that reflected consecutive arrival at the ED. The Composite International Diagnostic Interview Core was used to obtain a diagnosis of DSM-IV alcohol dependence and alcohol abuse; quantity and frequency of drinking and drunkenness as well as usual number of drinks consumed during the last year. Setting Participants were 5195 injured and non-injured patients attending seven EDs in four countries: Argentina, Mexico, Poland and the United States (between 1995,2001). Findings Using exploratory factor analyses alcohol use disorders can be described as a single, unidimensional continuum without any clear-cut distinction between the criteria for dependence and abuse in all sites. Results from item response theory analyses showed that the current DSM-IV criteria tap people in the middle,upper end of the alcohol use disorder continuum. Alcohol consumption (amount and frequency of use) can be used in all EDs with the current DSM-IV diagnostic criteria to help tap the middle,lower part of this continuum. Even though some specific diagnostic criteria and some alcohol consumption variables showed differential item function across sites, test response curves were invariant for ED sites and their inclusion would not impact the final (total) performance of the diagnostic system. Conclusions DSM-IV abuse and dependence form a unidimensional continuum in ED patients regardless of country of survey. Alcohol consumption variables, if added, would help to tap patients with more moderate severity. The DSM diagnostic system for alcohol use disorders showed invariance and performed extremely well in these samples. [source]

Classification System for the Completely Dentate Patient

JOURNAL OF PROSTHODONTICS, Issue 2 2004
Thomas J. McGarry DDS
The American College of Prosthodontists (ACP) has developed a classification system designed for use by dental professionals in the diagnosis and treatment of completely dentate patients. This classification is the third in a series and is similar to the Classifications for Complete Edentulism and Partial Edentulism previously developed by the ACP. These guidelines are intended to aid practitioners in the systematic diagnosis of each patient which, in turn, should lead to an appropriate treatment. Four categories of a completely dentate situation are defined (Class I,IV), differentiated by specific diagnostic criteria, with Class I representing an uncomplicated clinical situation and Class IV representing the most complex clinical situation. Potential benefits of the system include (1) improved intraoperator consistency, (2) improved professional communication, (3) insurance reimbursement commensurate with complexity of care, (4) an improved screening tool for dental school admission clinics, (5) standardized criteria for outcomes assessment and research, (6) enhanced diagnostic consistency, and (7) a simplified aid in the decision-making process associated with referral.

Case for and against specificity of depression in Alzheimer's disease

PSYCHIATRY AND CLINICAL NEUROSCIENCES, Issue 4 2010
Christian Even MD
Aims:, The aims of this study were to assess the epidemiological, phenomenological, and pathophysiological evidence that suggests the specificity of depression associated with Alzheimer's disease (AD). Methods:, We reviewed the English-language literature. Results:, Depression occurs significantly more often in patients with AD than in the general elderly population. While development of depression in response to the disability and emotional stress of AD may be a contributory factor in some patients, several studies showed that depression was not, or was only seldom, related to self-awareness of AD and these studies could not explain the high prevalence figures. To overcome the overlapping phenomenology of the two diseases, specific diagnostic criteria have been developed for depression in this context. Mixed findings have come from neuropathological and neuroimaging studies, with some evidence linking the underlying neural substrate of AD and depression, suggesting an overlapping cause of primary depression and depression comorbid with AD. Few randomized controlled trials for depression associated with AD have been conducted, with rather poor results for the use of antidepressants. Conclusions:, Currently, depression associated with AD is not considered a separate disorder by regulatory authorities and is unlikely to be considered as such in the near future. Several obstacles remain to support such a specific position, including the heterogenous nature of depression in general and within AD itself, the lack of a distinct set of symptoms, and limited treatment.
