PURPOSE OF REVIEW: New psychoactive substances (NPS) continue to emerge globally and present a threat to public health. This article summarizes the most recent literature on approaches for monitoring NPS use and adverse events related to use. RECENT FINDINGS: A variety of approaches have recently been employed for surveillance of NPS use and associated harms, including the use of toxicology testing of patients in emergency departments, surveys of sentinel populations, drug checking and syringe services programs, wastewater-based epidemiology, and retrospective analyses of clinical samples and toxicology reports...

PURPOSE OF REVIEW: Controversy remains about the difference in mental health status among children and adolescents between one-child and multichild families in China. Thus, we conducted a meta-analysis of studies comparing mental health status between both groups and explored their potential moderating factors. RECENT FINDINGS: Totally, 113 eligible studies encompassing 237 899 participants (one-child families: 83 125; multichild families: 154 774) were included...

PURPOSE OF REVIEW: The assumption has been made that urbanization adversely affects mental health, primarily attributed to the lack of access to nature. Our objective is to examine whether nature-based interventions can reduce psychopathology within an urban setting. RECENT FINDINGS: Nature-based interventions are generally categorized as either physical or virtual. Physical interventions engage participants in various activities like passive exposure, outdoor swimming, or physical activities in natural environments...

PURPOSE OF REVIEW: About one in four children in China is a migrant child. This population has a higher risk of experiencing loneliness. However, existing studies present conflicting findings regarding the levels of loneliness among migrant children as compared to local urban children in urban China. This review performs a meta-analysis of studies comparing loneliness levels between these two groups. RECENT FINDINGS: A literature search of major Chinese- and English-language databases revealed 27 eligible comparative studies...

PURPOSE OF REVIEW: Social withdrawal syndrome, known as "hikikomori," has been highlighted since the late 1990 s in Japan. Hikikomori is more common in urban areas, and often comorbid with mental disorders, and now spreading throughout the world. In the post-COVID-19 era, not outing is no longer considered pathological in itself as the "new normal," and a novel concept of hikikomori is needed. This review summarizes the concept of hikikomori, and presents the latest methods for identification of hikikomori...

PURPOSE OF REVIEW: Schizophrenia Spectrum Disorders (SSD) are severe conditions that frequently produce significant impairment in cognitive performance, social skills and psychosocial functioning. As pharmacological treatment alone often provides only limited improvements on these outcomes, several psychosocial interventions are employed in psychiatric rehabilitation practice to improve of real-world outcomes of people living with SSD: the present review aims to provide a critical overview of these treatments, focusing on those that show consistent evidence of effectiveness...

PURPOSE OF REVIEW: This review aims to provide an update on the association between urbanization and psychotic spectrum disorders, focusing on specific aspects of the urban environment that could be a bane or boon for the risk of psychosis. RECENT FINDINGS: Majority of the included studies support previous evidence suggesting that urbanization is linked to a higher risk of psychotic experiences and psychotic spectrum disorders. A small minority, however, have also found specific factors in the urban environment that could give rise to positive outcomes, such as better social functioning and lower mortality rates in psychotic spectrum disorders, or mitigate the risks associated with urbanization...

PURPOSE OF REVIEW: Economic development and urbanisation have prompted many Chinese parents to move from rural to urban regions for better job opportunities. Their children, who remain behind in rural regions, become left-behind children (LBC). With absent parents, children and adolescents are unable to maintain the secure attachment required for healthy social and emotional development, increasing the risk of mental illness. This study aimed to compare risk of self-harm and suicidal ideation in LBC and non-LBC in China...

PURPOSE OF REVIEW: Urbanization is a multifaceted process that can have both positive and negative effects on mental health, especially in adolescents. This paper attempts to summarize the impact of urbanization on youth mental health in Hong Kong. RECENT FINDINGS: Several studies have shown that urbanization is associated with an increased risk of youth mental health problems in Hong Kong. Psychosocial factors like perceived stress, social isolation, and exposure to environmental pollutants may contribute to a negative association between urbanization and mental health issues...

PURPOSE OF REVIEW: To provide a summary of the most up-to-date thoughts about treatment for schizophrenia at different stages of illness. RECENT FINDINGS: The use of Coordinated Specialty Care clinics has arisen as the standard for early on in the treatment of psychosis, providing the notion that recovery is possible. New medications that do not depend on postsynaptic dopamine receptor blockade are soon becoming available. SUMMARY: A focus should be made by clinicians to personalize treatment plans for each patient who has the possibility of being diagnosed with a primary psychosis and the plan should be to predict outcomes based on biological markers that include genetic vulnerability, early psychosocial combined with pharmacological treatments as needed and then a plan to determine or maintain treatments going forward into the future...

PURPOSE OF REVIEW: Urbanization, a complex global phenomenon, has a significant bearing on schizophrenia/psychosis burden through various socioeconomic and environmental factors. This review focuses on recent evidence (2019-2023) linking urbanization, schizophrenia, and the role of green space. RECENT FINDINGS: This review analyzed 43 articles that examined the correlation between urban birth or upbringing, urban living (urbanicity), and various schizophrenia/psychosis-related outcomes such as incidence, psychotic experiences, etc...

PURPOSE OF REVIEW: Perinatal mental health research provides an important perspective on neurobehavioral development. Here, we aim to review the association of maternal perinatal health with offspring neurodevelopment, providing an update on (self-)regulation problems, hypothesized mechanistic pathways, progress and challenges, and implications for mental health. RECENT FINDINGS: (1) Meta-analyses confirm that maternal perinatal mental distress is associated with (self-)regulation problems which constitute cognitive, behavioral, and affective social-emotional problems, while exposure to positive parental mental health has a positive impact...

PURPOSE OF REVIEW: This review summarizes recent evidence related to the cognitive trajectories of aging, the factors associated with the different trajectories, and the effect of sex on cognitive decline. RECENT FINDINGS: Trajectories of cognitive aging identified in different studies vary in number, in the proportion of individuals falling into each of the classes and in the predictors of class membership. Trajectories observed include types with 'rapid decline', those with 'gradual decline' and those with 'maintenance of high level' of cognitive performance...

PURPOSE OF REVIEW: Tourette syndrome (TS) and chronic tic disorders, collectively referred to as TS, are relatively common childhood onset neuropsychiatric conditions associated with functional impairment and distress. Over the past several years, clinical research has contributed to the advancement of the field's understanding of mechanisms and clinical correlates of TS. This progress has led to the development of key assessment tools and the implementation of novel interventions for individuals with TS...

PURPOSE OF REVIEW: To offer an integrative overview of mental health services in urban areas across different social groups and underscore the challenges and potential solutions to improve access to mental health services in urban areas. RECENT FINDINGS: The process of urbanization places a lot of tolls on the current mental health services system. Challenges to both mental health and mental health services include the elevated risk of some mental and behavioral health issues, the increased demand for mental health services, and the intensification of mental health inequalities...

PURPOSE OF REVIEW: Noninvasive brain stimulation (NIBS) is a promising method for altering cortical excitability with clinical implications. It has been increasingly used in children, especially in neurodevelopmental disorders. Yet, its safety and applications in the developing brain require further investigation. This review aims to provide an overview of the safety of commonly used NIBS techniques in children, including transcranial electrical stimulation (tES) and transcranial magnetic stimulation (TMS)...

PURPOSE OF REVIEW: The circular interactions between type 2 diabetes (TMD2) and major depressive disorder (MDD) are well documented but the understanding of their mechanisms has only recently gained more clarity. Latest research indicates, that the association between TMD2 and MDD is largely mediated by insulin resistance (IR). RECENT FINDINGS: A metabolic subtype of MDD can be distinguished from other MDD subpopulations, that is characterized by predominantly atypical clinical presentation, IR and different responsiveness to antidepressant interventions...

PURPOSE OF REVIEW: Attention deficit hyperactivity disorder (ADHD) is a common psychiatric disorder and is associated with an increased risk of suicidal behavior, especially in females. The differences in the presentation of ADHD in females, factors contributing to suicidality and the effects of therapeutic interventions are presented in this review to highlight the relationship between ADHD and suicidality and self-harm behavior. RECENT FINDINGS: Impulsivity, an inherent symptom of ADHD, commonly acts as a risk factor of suicidality and is associated with both suicidal behavior and nonsuicidal self-injury...

PURPOSE OF REVIEW: Displaced persons around the world have intensified in the previous decade and are predicted to rise further with greater global instability. The mental health issues involved with fleeing one's home, and attempting to make a new life in a host country need to be understood and addressed. RECENT FINDINGS: Prevalence of anxiety and mood disorders, including posttraumatic stress disorder appear to be higher for displaced peoples than for the population in the host country...
