Autism spectrum disorder (ASD) is a condition with onset in early childhood characterized by marked deficits in interpersonal interactions and communication and by a restricted and repetitive range of interests and activities. This review points out key recent findings utilizing molecular imaging including magnetic resonance spectroscopy (MRS) and nuclear neuroimaging techniques such as positron emission tomography (PET) and single-photon emission computed tomography (SPECT). MRS indicates an excitatory/inhibitory imbalance in high-functioning autism...

Addiction is composed of three phases: intoxication, withdrawal, and craving. Negative reinforcement, strengthening a behaviour by removing an aversive stimulus, has been associated with the withdrawal phase. An imbalance of neurotransmitters within the brain's stress (nociceptin, neuropeptide Y) and anti-stress (CRF, norepinephrine, etc.) system is attributed to negatively reinforced compulsive behaviours associated with relapse. Similarly, post-traumatic stress disorder is characterized by an overactive stress system...

Schizophrenia is a chronic psychiatric disorder generally preceded by a so-called prodromal phase, which is characterized by attenuated psychotic symptoms. Advances in clinical research have enabled prospective identification of those individuals who are at clinical high risk (CHR) for psychosis, with the power to predict psychosis onset within the near future. Changes in several brain neurochemical systems and molecular mechanisms are implicated in the pathophysiology of schizophrenia and the psychosis spectrum, including the dopaminergic, γ-aminobutyric acid (GABA)-ergic, glutamatergic, endocannabinoid, and immunologic (i...

Currently, the differential diagnosis between atypical parkinsonisms and classical idiopathic Parkinson's disease can be quite difficult because of the significant overlap of clinical presentation and symptoms. Neurodegenerative conditions, including progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and frontotemporal dementia (FTD), are primarily characterized by accumulation of tau protein in the brain. Recent imaging developments for tau pathology may provide a promising tool for the assessment of diagnosis, prognosis, and progression of these neurodegenerative disorders...

This study reviews previous studies that employ positron emission tomography (PET) imaging assessments in Parkinson's disease (PD) patients with and without Impulsive Compulsive Behaviours (ICB). This begins with a summary of the potential benefits and limitations of commonly utilized ligands, specifically D2/3 receptor and dopamine transporter ligands. Since previous findings emphasize the role of the ventral striatum in the manifestation of ICBs, this study attempts to relate these imaging findings to changes in behaviour, especially emphasizing work performed in substance abuse and addiction...

The prevalence of mood disorders in the rapidly-growing older adult population merits attention due to the likelihood of increased medical comorbidities, risk of hospitalization or institutionalization, and strains placed on caregivers and healthcare providers. Magnetic resonance spectroscopy (MRS) quantifies biochemical compounds in vivo, and has been used specifically for analyses of neural metabolism and bioenergetics in older adults with mood disorders, usually via proton or phosphorous spectroscopy. While yet to be clinically implemented, data gathered from research subjects may help indicate potential biomarkers of disease state or trait or putative drug targets...

Ovarian hormones, particularly oestrogen and progesterone, undergo major fluctuations across the female lifespan. These hormone transition periods, such as the transition from pregnancy to postpartum, as well as the transition into menopause (perimenopause), are also known to be times of elevated susceptibility to depression. This study reviews how these transition periods likely influence neurochemical changes in the brain that result in disease vulnerability. While there are known associations between oestrogen/progesterone and different monoaminergic systems, the interactions and their potential implications for mood disorders are relatively unknown...

Colin B Josephson, Nathalie Jetté
Psychiatric comorbidities, including mood, anxiety, and psychotic disorders, are common in epilepsy, often occurring at rates 2-3-fold or higher than in the general population without epilepsy. This article discusses the epidemiology of psychiatric disorders in epilepsy, hypotheses regarding the pathogenesis of these comorbidities, and treatment implications. More specifically, it addresses: (1) How common are major depressive disorder, anxiety disorders, and psychotic disorders in epilepsy? (2) How does one screen for these psychiatric disorders in persons with epilepsy? (3) Why do psychiatric conditions occur in epilepsy? (4) Is the treatment of psychiatric comorbidity in epilepsy associated with seizures? The important topic of suicide and suicidal ideation in epilepsy, risk factors for their occurrence, and how to screen for these co-existent conditions is also discussed...

Fibromyalgia (FM) is a central sensitization syndrome characterized by chronic widespread pain. FM is often comorbid with psychiatric disorders, as well as psychological distress that worsens the quality-of-life of people affected. The aim was to collect current evidence about the management of FM from a psychosomatic perspective. The literature was synthesized and summarized in a narrative format. The literature search was carried out in PubMed; review articles, meta-analysis, overview, and guidelines published in the last 10 years written in English were included...

The association between panic disorder (PD) and cardiovascular diseases (CVD) has been extensively studied in recent years and, although some studies have shown anxiety disorders co-existing or increasing the risk of heart disease, no causal hypothesis has been well established. Thus, a critical review was performed of the studies that evaluated the association between PD and cardiovascular diseases; synthesizing the evidence on the mechanisms mediators that theoretically would be the responsible for the causal pathway between PD and CVD, specifically...

The psychiatric, psychosocial, and existential/spiritual pain determined by chronic medical disorders, especially if in advanced stages, have been repeatedly underlined. The right to approach patients as persons, rather than symptoms of organs to be repaired, has also been reported, from Paul Tournier to Karl Jaspers, in opposition and contrast with the technically-enhanced evidence-based domain of sciences that have reduced the patients to 'objects' and weakened the physician's identity deprived of its ethical value of meeting, listening, and treating subjects...

The declaration of a caliphate by Islamic State in June 2014 witnessed the recruitment of increasing numbers of foreign terrorist fighters drawn from a diverse range of nations across the globe. This paper seeks to explore the appeal of extreme groups and how recruiters persuade young people to risk either their lives or lengthy terms of imprisonment. The processes of radicalization and recruitment are differentiated and compared with conventional means of encouraging individuals to enlist in state-sanctioned armed forces...

#17
Roger Griffin
The psychiatrist Robert Lifton developed his model of 'doubling' to account for the capacity of some human beings to commit atrocities in one compartment of their lives, while continuing to maintain normal social relations in their domestic sphere, a phenomenon which he encountered both in interviews with former Nazi doctors working in concentration camps, and with terrorists belonging to the Japanese Aum Shinrikyo cult. By supplementing this model with a theory of heroization based on existential anthropology and Jung's concept of the Shadow, a composite heuristic explanatory paradigm is formed, 'heroic doubling', which may contribute to the empathetic understanding of acts of extreme violence being carried out by individuals who do not present symptoms of psychiatric disorder and maintain normal existences, yet are prepared to kill and be killed for a cause that confers on their lives a sense of transcendent purpose and sacrality...

Neil Krishan Aggarwal
Scholars, politicians, and policy-makers have increasingly pointed to the role of narratives in recruiting militants and justifying violence, highlighting the need for counter-narratives that promote peace. However, few have offered concrete guidelines on how to construct counter-narratives. This exploratory study uses prototype theory from social psychology to analyse Taliban narratives written in Arabic on the historical figure Maḥmūd of Ghaznī (971-1030), who is portrayed as a figure worthy of emulation...

Recent high-profile cases and scientific research on lone actor terrorist attackers have indicated that there may be an association with mental illness. Simultaneously, countering violent extremism (CVE) initiatives have recently been placing more emphasis on building intervention (aka secondary prevention) programmes to address this matter, with mental health professionals possibly playing important roles in preventing lone actor terrorist attacks. Mental health professionals can contribute to intervention programmes, as practitioners and as leaders, but more so by drawing upon the threat assessment model, than because of a possible association with mental illness...

Immigration to Italy has been increasing exponentially in the last decades due to the international political changes and conflicts in the Middle East. The relationship between immigration and crimes is a debated issue, and violent radicalization of second or third generations of migrants is under increased scrutiny. Consequently, many politicians and political parties use nationalist and xenophobic language. Inevitably, this will have an impact on reactions of the larger population, as well as that of migrants...
