Progress in understanding the underlying neurobiology of obsessive-compulsive disorder (OCD) has stalled in part because of the considerable problem of heterogeneity within this diagnostic category, and homogeneity across other putatively discrete, diagnostic categories. As psychiatry begins to recognize the shortcomings of a purely symptom-based psychiatric nosology, new data-driven approaches have begun to be utilized with the goal of solving these problems: specifically, identifying trans-diagnostic aspects of clinical phenomenology based on their association with neurobiological processes...

The reliability and validity of traditional taxonomies are limited by arbitrary boundaries between psychopathology and normality, often unclear boundaries between disorders, frequent disorder co-occurrence, heterogeneity within disorders, and diagnostic instability. These taxonomies went beyond evidence available on the structure of psychopathology and were shaped by a variety of other considerations, which may explain the aforementioned shortcomings. The Hierarchical Taxonomy Of Psychopathology (HiTOP) model has emerged as a research effort to address these problems...

Hypersexuality refers to abnormally increased or extreme involvement in any sexual activity. It is clinically challenging, presents trans-diagnostically and there is extensive medical literature addressing nosology, pathogenesis and neuropsychiatric aspects. Classification includes deviant behaviours, diagnosable entities related to impulsivity, and obsessional phenomena. Some clinicians view an increase in sexual desire as 'normal' while psychodynamic theorists consider it ego-defensive at times alleviating unconscious anxiety rooted in intrapsychic conflicts...

Since 1998, two developments have led to concerns that the EDS nosology needs to be substantially revised. The first development was the clinical and molecular characterization of several new EDS variants, which substantially broadened the molecular basis underlying EDS. The second was the growing concern, in the absence of genetic diagnosis, that the hypermobile type of EDS had an expanded phenotype, may be genetically heterogeneous, and that the diagnostic criteria currently in use were inadequate. Furthermore, there is a dire need for the development of guidelines for management for each type of EDS to allow both the specialist and the generalist to care for affected individuals and their families...

There has been a surge in interest in and research on narcissism and narcissistic personality disorder (NPD). Despite or because of this increased attention, there are several areas of substantial debate that surround the construct, including descriptions of grandiose and vulnerable dimensions or variants, questions regarding the existence of a consensual description, central versus peripheral features of narcissism, distinctions between normal and pathological narcissism, possible etiological factors, the role of self-esteem narcissism, where narcissism should be studied, how it can be assessed, and its representation in diagnostic nosologies...

Emil Kraepelin (1856-1926) is considered one of the founders of modern psychiatric nosology. However, his conceptualization of obsessive-compulsive phenomena is relatively understudied. In this article, we compare and contrast excerpts from the eighth edition (1909-1915) of Kraepelin's Textbook of Clinical Psychiatry focusing on what Kraepelin called "obsessive neurosis" and related "original pathological conditions" with the current DSM-5 criteria for obsessive-compulsive disorder (OCD). Consistently with DSM-5 OCD, Kraepelin described obsessive neurosis as characterized by obsessive ideas, compulsive acts, or both together...

This short review highlights significant changes and recent findings incorporated to varying extent in the WHO 2016 definition of a variety of tumours, including peripheral nerve sheath tumours, meningiomas, mesenchymal non-meningothelial tumours, melanocytic tumours, lymphomas and histiocytic tumours, germ cell tumours and non-neuroendocrine pituitary tumours. Most notable classification changes include: adding "hybrid nerve sheath tumours" to the spectrum of benign nerve sheath tumours; an updated definition of atypical meningioma (WHO grade II), including cases with brain invasion; recognizing dural solitary fibrous tumour (SFT) and haemangiopericytoma (HPC) as a single tumour entity characterized by NAB2 and STAT6 gene fusions for which the term solitary SFT/HPC was chosen; recognizing that pituitary granular cell tumour, spindle cell oncocytoma, and pituicytoma all share nuclear expression of TTF-1, possibly representing a spectrum of a single nosological entity derived from posterior pituitary glial cells...

The Kraepelinian syndromal approach to diagnosis taken by DSM-III and its successors, which defines disorders by their clinical phenomenon, has come under rising criticism with increasing calls for an etiologically based nosology. The relative virtues of a syndromal versus etiologic psychiatric nosology have actually been debated within our field for a long time. To deepen and historically contextualize our current discussion, I review in detail the proposal for etiologic diagnostic systems for insanity by David Skae (1814-1873)...

BACKGROUND: Current group-average analysis suggests quantitative but not qualitative cognitive differences between schizophrenia (SZ) and bipolar disorder (BD). There is increasing recognition that cognitive within-group heterogeneity exists in both disorders, but it remains unclear as to whether between-group comparisons of performance in cognitive subgroups emerging from within each of these nosological categories uphold group-average findings. We addressed this by identifying cognitive subgroups in large samples of SZ and BD patients independently, and comparing their cognitive profiles...

The criteria for posttraumatic stress disorder PTSD have changed considerably with the newest edition of the American Psychiatric Association's (APA) Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Changes to the diagnostic criteria from the DSM-IV to DSM-5 include: the relocation of PTSD from the anxiety disorders category to a new diagnostic category named "Trauma and Stressor-related Disorders", the elimination of the subjective component to the definition of trauma, the explication and tightening of the definitions of trauma and exposure to it, the increase and rearrangement of the symptoms criteria, and changes in additional criteria and specifiers...

Classical EDS is a heritable disorder of connective tissue. Patients are affected with joint hypermobility, skin hyperextensibilty, and skin fragility leading to atrophic scarring and significant bruising. These clinical features suggest consideration of the diagnosis which then needs to be confirmed, preferably by genetic testing. The most recent criteria for the diagnosis of EDS were devised in Villefranche in 1997. [Beighton et al. (1998); Am J Med Genet 77:31-37]. The aims set out in the Villefranche Criteria were: to enable diagnostic uniformity for clinical and research purposes, to understand the natural history of each subtype of EDS, to inform management and genetic counselling, and to identify potential areas of research...

In the last decade, growing attention has been placed on joint hypermobility and related disorders. The new nosology for Ehlers-Danlos syndrome (EDS), the best-known and probably the most common of the disorders featuring joint hypermobility, identifies more than 20 different types of EDS, and highlights the need for a single set of criteria to substitute the previous ones for the overlapping EDS hypermobility type and joint hypermobility syndrome. Joint hypermobility is a feature commonly encountered in many other disorders, both genetic and acquired, and this finding is attracting the attention of an increasing number of medical and non-medical disciplines...

A longstanding nosological question in the clinical literature is whether substance use disorders (SUDs) are best conceptualized as categorical or dimensional phenomena. Taxometric analysis is a statistical approach uniquely developed to address this issue. To date, no taxometric studies have been conducted with SUDs in adolescents. The current taxometric study investigated the latent structure of SUDs in adolescents for four different substances: marijuana, analgesics, hallucinogens, and inhalants. Interview-derived data for DSM-IV SUD symptoms were drawn from the National Survey on Drug Use and Health, pooled across the years 2004 to 2013 (unweighted n = 181,573; 48...

BACKGROUND: Mild behavioral impairment (MBI) is a construct that describes the emergence at ≥50 years of age of sustained and impactful neuropsychiatric symptoms (NPS), as a precursor to cognitive decline and dementia. MBI describes NPS of any severity, which are not captured by traditional psychiatric nosology, persist for at least 6 months, and occur in advance of or in concert with mild cognitive impairment. While the detection and description of MBI has been operationalized in the International Society to Advance Alzheimer's Research and Treatment - Alzheimer's Association (ISTAART-AA) research diagnostic criteria, there is no instrument that accurately reflects MBI as described...

Mixed features specifier (MFS) is a new nosological entity defined and operationalized in the Diagnostic and Statistical Manual of Mental Disorders (DSM), 5th Edition. The impetus to introduce the MFS and supplant mixed states was protean, including the lack of ecological validity, high rates of misdiagnosis, and guideline discordant treatment for mixed states. Mixed features specifier identifies a phenotype in psychiatry with greater illness burden, as evidenced by earlier age at onset, higher episode frequency and chronicity, psychiatric and medical comorbidity, suicidality, and suboptimal response to conventional antidepressants...

The reliability and validity of psychiatric diagnoses have always been a major concern. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) reliability field trials yielded ambiguous results, with some diagnostic categories scoring well below par. We argue that the emphasis on the reliability of psychiatric diagnoses, which has dominated psychiatric nosology and guided the endeavor of improving the DSM in its consecutive editions, is misguided and lacks in structural validity. In this article, we defend a pragmatic view on psychiatric disease as the most fruitful approach to an understanding of what the categorical distinctions in the DSM (can) represent...

The treatment of post-ictal psychosis has foundered on uncertainty in diagnosis of psychotic phenotypes, and equivocal efficacy of first and second generation antipsychotics. This article presents a case history of comorbid temporal lobe epilepsy and psychosis, suggests the applicability of the continental, cycloid psychosis diagnostic conceptualization to post-ictal psychoses, and demonstrates the efficacy of lithium in their treatment. Clinical studies of comorbidity of epilepsy and psychosis offer great potential as a basis for modelling brain-mind relationships, and neuropsychiatric nosology, pathophysiology and treatment...
