Small cell lung cancer (SCLC) is the most malignant pathological type of lung cancer with the highest mortality, and the incidence of brain metastasis (BM) is in high frequency. So far, prophylactic cranial irradiation (PCI) has been suggested as an effective treatment for preventing brain metastasis of SCLC. PCI has long been applied to limited-stage SCLC (LS-SCLC) patients who have achieved complete remission after radiotherapy and chemotherapy as a standard treatment. However, the neurocognitive decline is a major concern surrounding PCI. New therapeutic approaches targeting PCI-induced neurotoxicity, including hippocampal protection or memantine, have been increasingly incorporated into the therapeutic interventions of PCI. Helical tomotherapy, RapidArc, and Volumetric-modulated arc therapy (VMAT) with a head-tilting baseplate are recommended for hippocampal protection. Besides, in the MRI and immunotherapy era, the significance of PCI in SCLC patients is controversial. SCLC patients with PCI should be recruited in clinical trials since this is the only way to improve the existing standard of care. This review summarizes the current therapeutic strategy and dilemma over PCI for SCLC, providing a theoretical basis for clinical decision-making and suggestions for PCI practice in clinical.

BACKGROUND: Cognitive dysfunction may be one of the hazardous late effects among survivors of pediatric hematological malignancies. Our study aimed to explore cognitive performance and assess the global and regional brain volume changes in survivors of hematological malignancies.
METHODS: This case-control study was conducted on 68 survivors of hematological malignancies, with a median follow-up period of 2 years (ranging from 1 to 6.2 years). Stanford-Binet Test was used for cognitive assessment. A quantitative volumetric assessment of the brain was done using the NeuroQuant Brain Magnetic Resonance. Age and sex-matched 68 children were selected as a comparison group.
RESULTS: Cancer survivors showed significantly lower levels of IQ and their subtests than the control group. Global brain atrophy was observed in the majority of the survivors. Many risk factors significantly affected different IQ subtests, such as radiotherapy (RTH), high cumulative doses of methotrexate (MTX), and prednisone. At the same time, low white matter volume (WMV) was observed with higher cumulative doses of MTX and anthracyclines.
CONCLUSIONS: Hematological malignancies have a negative impact on cognition. Neurocognitive impairment and related brain changes were evident in those who received RTH, HDMTX, or high cumulative doses of steroids.

UNASSIGNED: We evaluated the effects of kidney failure etiology, dialysis, and sociodemographic factors on the subdomains of intellectual functioning in pediatric kidney transplant candidates.
UNASSIGNED: This retrospective study included 78 pediatric kidney transplant candidates who completed a Wechsler Intelligence Scale assessment during pre-transplant neuropsychological evaluation between 1/1/2010 and 10/31/2022. Linear regression models were employed to examine the effects of kidney failure etiology, dialysis status, neighborhood area deprivation, and race on subdomains of intellectual functioning.
UNASSIGNED: The mean scores of various intellectual functioning domains in pediatric kidney transplant candidates were significantly lower than in the general population (ps <0.001). After adjusting for covariates, patients with congenital anomalies of the kidney and urinary tract had significantly lower processing speed (M=85; 95% CI: 79-91) compared to patients with nephrotic syndrome (M=99; 95% CI: 90-107) and other etiologies (M=84; 95% CI: 78-90) (p=0.003). Patients living in high-level deprivation neighborhoods showed lower working memory performance (M=84, 95% CI: 77-91) than patients living in median-level (M=91, 95% CI: 87-95) and low-level (M=98, 95% CI: 92-104) neighborhood area deprivation (p=0.03). Patients from marginalized racial groups demonstrated lower verbal skills (M=80, 95% CI: 74-87) than White patients (M=92, 95% CI: 88-97) (p=0.02). Additionally, patients receiving dialysis showed higher reasoning skills (M=98, 95% CI: 90-104) than patients without dialysis (M= 90, 95% CI: 86-95) (p=0.04).
UNASSIGNED: Neurocognitive development in pediatric kidney transplant candidates is associated with medical and sociodemographic factors. Strategies to monitor, treat, and accommodate neurocognitive concerns need to be considered to optimize long-term medical and social outcomes.

OBJECTIVE: To assess in patients with 1-10 brain metastases, each of which has been treated by neurosurgery or stereotactic radiosurgery, whether hippocampal sparing whole brain radiotherapy (HS-WBRT) better spares neurocognitive function (NCF) than standard WBRT. Further, to assess whether a phase III randomised trial of HS-WBRT would be feasible in the UK.
METHODS: A multicentre, randomised, open label phase II trial was undertaken, randomising patients to 30Gy in 10 fractions of WBRT or HS-WBRT. The primary endpoint was decline in Total recall using Hopkins Verbal Learning Test Revised (HVLT-R) at 4 months post treatment. To assess this, we aimed to recruit 84 patients over 3 years. Secondary endpoints included further measures of NCF, quality of life, duration of functional independence, local control of treated metastases, development of new metastases, disease control within the hippocampal regions, overall survival, steroid and antiepileptic medication requirements, and toxicity.
RESULTS: The trial closed prematurely due to slower than anticipated recruitment. From April 2016 to January 2018, 23 patients were randomised. Follow up was a median of 25 months. Fifteen patients (6 WBRT, 9 HS-WBRT) were assessed for the primary endpoint; of these, 1 in each arm experienced significant decline in the 4-month HVLT-R Total recall score (p = 0.8). Patients in the HS-WBRT arm experienced less insomnia (p < 0.01) and drowsiness (p < 0.01). There were no differences in other secondary endpoints.
CONCLUSIONS: A phase III randomised trial of HS-WBRT was shown not to be feasible at this time in the UK. As most randomised trials of HS-WBRT reported to date share common endpoints, including NCF, an individual patient data meta-analysis should be undertaken.

Victoria has new legislation, the Mental Health and Wellbeing Act 2022 (Vic) (MHWA) to govern the care and treatment of people with mental illness that came into effect on 1 September 2023. It takes a human rights approach with a focus on person-centred care. The definition of mental illness encompasses conditions such as dementia even though it is rarely used to manage such conditions. How would the management of dementia and associated conditions change if these conditions were managed under the MHWA? This article uses dementia to examine the differences between the new MHWA, the Medical Treatment Planning and Decisions Act 2016 (Vic) and the Guardianship and Administration Act 2019 (Vic) and how the human rights approach taken by the MHWA might inform future directions in managing dementia.

Encephalopathy is part of the clinical triad of Susac syndrome, but a detailed understanding of the neurocognitive and neuropsychiatric profile of this condition is lacking. Existing literature indicates that cognitive deficits range in severity from subtle to profound. Executive function and short-term recall are affected frequently. Psychiatric manifestations may be absent or may include anxiety, mood disorders or psychosis. If psychiatric phenomena develop during the disease course, it can be hard to disentangle whether symptoms directly relate to the pathology of Susac syndrome or are secondary to treatment-related side effects. In this article, we review what is known about the cognitive and psychiatric morbidity of Susac syndrome and identify areas where knowledge is deficient. Importantly, we also provide a framework for future research, arguing that better phenotyping, understanding of pathophysiology, evaluation of treatments on cognitive and psychiatric outcomes, and longitudinal data capture are vital to improving patient outcomes.

The Tower of London, Drexel Version, Second Edition (TOL-DX) is purported to measure multiple aspects of executive functions, although it also possesses inherent non-executive demands. Such complexity makes it useful in detecting impairment but difficult in interpreting the neurocognitive cause of impairment, particularly in children. This study investigated the developmental, neurocognitive, and symptom correlates of the TOL-DX in children and adolescents with neuropsychiatric disorders. Two-hundred and thirty-three children and adolescents (7-21 years old) completed the TOL-DX during a neuropsychological evaluation as part of clinical care within a children\'s psychiatric hospital. Pearson correlation, regression models, and receiver operating characteristic curve (ROC) analyses examined the association among variables. Visuospatial and executive functions (EF) were most consistently related to total moves, execution time, and violations. TOL-DX variables were associated with attention in younger participants and EF in older participants. No TOL-DX scores were related to parent-reported symptoms. The TOL-DX possesses inherent visuospatial and attention/executive demands in children and adolescents which are difficult to differentiate, differ by age group, and not associated to clinical symptoms. Taken together, the TOL-DX is complex to interpret, but psychometrically sound and sensitive to neurocognitive impairment in children and adolescents with transdiagnostic neuropsychiatric disorders.

BACKGROUND: X-Linked Myotubular Myopathy (XLMTM) is a severe congenital myopathy, potentially fatal within the first years. Patients present several complications and their cognitive development has never been explored deeply so far. An in-depth knowledge on the disease natural history, including the neurocognitive and adaptive profile, is essential in light of the promising new therapeutic perspectives.
METHODS: We included all XLMTM patients seen in our clinical Unit between January 2021 and December 2023, irrespective to their disease\'s severity. Demographic and clinical data, including motor, respiratory and swallowing functions were collected. Patients were assessed with gold-standard international scales, according to their age and communication skills.
RESULTS: We assessed nine patients in total, four with a severe phenotype, four with an intermediate phenotype and one with mild phenotype. The cognitive profile was within the lower limits or lower than the norm, with a global adaptive deficit for the majority of patients. A perseverative behavioural trait was also observed in some patients.
CONCLUSIONS: This study shows that XLMTM patients in the cohort had a neurodevelopmental profile within the lower limits of the norm, irrespective to the disease\'s severity, while the adaptive difficulties seems to be related to patients\' global clinical impairment. Our observation would deserve a confirmation on a wider range of patients and we consider it essential for better defining the XLMTM phenotype, also considering the incoming promising therapeutic approaches.

A common infection, human cytomegalovirus (HCMV) has been associated with a variety of human diseases, including cardiovascular disease and possibly certain cancers. HCMV has also been associated with cognitive, psychiatric, and neurological conditions. Children with congenital or early-life HCMV are at risk for microcephaly, cerebral palsy, and sensorineural hearing loss, although in many cases sensorineural loss may resolve. In addition, HCMV can be associated with neurodevelopmental impairment, which may improve with time. In young, middle-aged, and older adults, HCMV has been adversely associated with cognitive function in some but not in all studies. Research has linked HCMV to Alzheimer\'s and vascular dementia, but again not all findings consistently support these associations. In addition, HCMV has been associated with depressive disorder, bipolar disorder, anxiety, and autism-spectrum disorder, although the available findings are likewise inconsistent. Given associations between HCMV and a variety of neurocognitive and neuropsychiatric disorders, additional research investigating reasons for the considerable inconsistencies in the currently available findings is needed. Additional meta-analyses and more longitudinal studies are needed as well. Research into the effects of antiviral medication on cognitive and neurological outcomes and continued efforts in vaccine development have potential to lower the neurocognitive, neuropsychiatric, and neurological burden of HCMV infection.

OBJECTIVE: Young offenders experience higher rates of neurodevelopmental and mental health disorders than the general population, and significant access barriers to health treatment. Treatment combining Cognitive Remediation Therapy (CRT) and Social Cognition Remediation Therapy (SCRT) has demonstrated benefits for functional improvements and social development. However, there is limited information regarding group treatment programs in custodial settings for young offenders. This pilot study explores the effectiveness and feasibility of a group treatment program for youth offenders with cognitive deficits and mental health concerns in youth detention.
METHODS: The School-Link Advantage pilot study designed and tested a 10-week group treatment program combining CRT and SCRT for young offenders in custody. The closed groups incorporated interactive activities focussed on emotional recognition and regulation skills, optimizing executive functioning, understanding values, exploring belief systems, improving relationships, and safety planning.
RESULTS: Of the 22 male participants recruited in an Australian Youth Justice Centre, 12 completed all aspects of the treatment program, reflecting a 54.5% completion rate in a typically challenging to engage population cohort. Results demonstrated significant improvements in the ability to store and retrieve information, recognize information, and control emotions. Planning and organizing skills also showed considerable development.
CONCLUSIONS: This pilot study suggests that a combined CRT and SCRT group treatment program has the potential to effectively target cognitive challenges associated with mental health disorders in young offenders in custody. These promising outcomes suggest exploring randomized controlled trials with increased cultural sensitivity for diverse populations.
