Down syndrome is the most common genetic cause of intellectual disability and Alzheimer's disease. In the general population, common mental disorders (CMDs), including anxiety, depression and obsessive–compulsive disorder, are linked to cognitive decline and higher risk for dementia. It is not known how CMDs affect longer-term cognitive outcomes in Down syndrome, and there is often diagnostic uncertainty in older people with Down syndrome and psychiatric comorbidity.

To study the influence of CMDs on cognitive ability and whether they are related longitudinally to development of clinical signs of Alzheimer's disease in Down syndrome.

We followed 115 individuals with Down syndrome, 27 of whom were diagnosed with a CMD, over approximately 3 years. Changes in cognitive and behavioural outcomes between baseline and follow-up assessment were analysed, with comparisons made between those with and without a comorbid CMD. Age, gender, apolipoprotein E status and level of intellectual disability were included as covariates.

No significant association between presence of a CMD and poorer performance on cognitive tasks or informant-rated decline over time was observed (P > 0.05).

Our results suggest that a diagnosis of a CMD does not have a significant negative effect on long-term cognitive or behavioural outcomes in individuals with Down syndrome. In individuals with stable or treated CMD, subsequent cognitive decline is likely indicative of Alzheimer's disease rather than a consequence of mental disorder.

Controversial data exist about the impact of Down syndrome on outcomes after surgical repair of atrioventricular septal defect.

(A) assess trends and outcomes of atrioventricular septal defect with and without Down syndrome and (B) determine risk factors associated with adverse outcomes after atrioventricular septal defect repair.

We queried The National Inpatient Sample using International Classification of Disease codes for patients with atrioventricular septal defect < 1 year of age from 2000 to 2018. Patients’ characteristics, co-morbidities, mortality, and healthcare utilisation were evaluated by comparing those with versus without Down syndrome.

In total, 2,318,706 patients with CHD were examined; of them, 61,101 (2.6%) had atrioventricular septal defect. The incidence of hospitalisation in infants with atrioventricular septal defect ranged from 4.5 to 7.5% of all infants hospitalised with CHD per year. A total of 33,453 (54.7%) patients were associated with Down syndrome. Double outlet right ventricle, coarctation of the aorta, and tetralogy of Fallot were the most commonly associated with CHD in 6.9, 5.7, and 4.3% of patients, respectively. Overall atrioventricular septal defect mortality was 6.3%. Multivariate analysis revealed that prematurity, low birth weight, pulmonary hypertension, and heart block were associated with mortality. Down syndrome was associated with a higher incidence of pulmonary hypertension (4.3 versus 2.8%, p < 0.001), less arrhythmia (6.6 versus 11.2%, p < 0.001), shorter duration for mechanical ventilation, shorter hospital stay, and less perioperative mortality (2.4 versus 11.1%, p < 0.001).

Trends in atrioventricular septal defect hospitalisation had been stable over time. Perioperative mortality in atrioventricular septal defect was associated with prematurity, low birth weight, pulmonary hypertension, heart block, acute kidney injury, and septicaemia. Down syndrome was present in more than half of atrioventricular septal defect patients and was associated with a higher incidence of pulmonary hypertension but less arrhythmia, lower mortality, shorter hospital stay, and less resource utilisation.

Co-morbid psychiatric disorders are common in Down syndrome (DS). Evidence is limited for pharmacotherapy, specifically antipsychotics, for psychiatric co-morbidity in DS.

To describe a case of a patient with DS who developed a first-episode psychosis (FEP) and who responded to lurasidone in monotherapy and to review recent literature on the treatment of psychosis in patients with DS.

(1) Case report: FEP in DS patient treated with lurasidone 37 mg/day. (2) Narrative review on the treatment of psychosis in DS patients through PubMed database (1990-2020). Key terms: “psychosis”, “Down Syndrome”, “pharmacological treatment”, “antipsychotic drugs”.

A 21-year-old woman with DS, without psychiatric history, presenting with behavioural anomalies, aggressiveness, soliloquies, and unmotivated laughs was referred to our outpatient clinic by her general practitioner. Symptoms began one year prior and progressively worsened, impairing her daily functionality. Previous blood workup was normal. She was diagnosed with FEP and began treatment with lurasidone 37 mg. At 4-week follow-up, she showed total remission of the psychotic symptoms, had no tolerability complaints, and returned to baseline functionality levels. Discussion: No reports of lurasidone use in psychosis in DS have been published. To treat psychotic symptoms in DS, most literature reports describe the use of typical antipsychotics, which are usually effective, but often poorly tolerated; atypical antipsychotics such as risperidone and aripiprazole have also been used.

Lurasidone may be a useful option in patients with FEP in DS. Further research is warranted on treatment of psychosis in this population.

Down syndrome (DS) is a complex condition that causes various health problems and it is accepted that treadmill training is a therapy method for some of them.

The objective was to evaluate the effectiveness of various results of treadmill training in children and adults with DS.

We included studies in which participants with DS from every age group received treadmill training, alone or combined with physiotherapy and could optionally be compared to a control group with patients with DS who did not use treadmill training. The search was conducted in medical databases: PubMed, PEDro, Science Direct, Scopus and Web of Science and involved trials published until July 2021. Following PRISMA criteria, the Risk of Bias assessment was conducted using a tool developed by the Cochrane Collaboration for RCT. The included studies presented multiple outcomes and various methodologies therefore we were not able to conduct any sort of data synthesis, we presented measures of treatment effect as mean differences and corresponding 95% confidence intervals.

5 studies with a total number of 687 participants were included. 10 trials reported on walking onset, 8 on gait parameters or cardiovascular functions, 4 on anti-inflammatory effect and 3 on executive or cognitive functions. We came across 25 different outcomes in different age groups which are presented in a narrative manner. In all outcomes we have observed a positive result favouring the treadmill training.

Introducing treadmill exercise into typical physiotherapy generates improvements of mental and physical health of people with DS of all ages.

We aimed to characterise the impact of Down syndrome on myocardial performance and loading conditions in infants with Down syndrome and CHD over the peri-operative period by comparing them with infants matched for cardiac lesion with a normal microarray.

Left ventricular global longitudinal strain, right ventricular free wall longitudinal strain, left ventricular end-systolic wall stress, and right ventricular systolic pressure were measured in the two groups over the peri-operative period.

Fifty-five infants had a diagnosis of Down syndrome and these were compared with 29 control infants. Left ventricular global longitudinal strain decreased in both groups post-operatively with the Down syndrome group demonstrating some recovery pre-discharge (18 ± 3 versus 16 ± 3 %, p = 0.01). Right ventricular longitudinal strain significantly decreased in both groups post-operatively with the control group demonstrating better recovery by hospital discharge (14 ± 4 versus 18 ± 6 %, p < 0.01). End-systolic wall stress was lower and right ventricular systolic pressure was higher in the Down syndrome group throughout the study period (all p < 0.05). Down syndrome was an independent predictor of the duration of ventilation, post-operative use of inotropes, and intensive care stay. Right ventricular longitudinal strain was an independent predictor of duration of intensive care stay.

This study demonstrates the difference between the two groups in relation to left and right ventricular function, particularly prior to discharge, and outlines the additional impact a diagnosis of Down syndrome has on myocardial performance during the peri-operative period.

According to Vygotsky, children with special needs follow the same trajectory of development as normally developing children, although some of the skills can be observed in a later period. This statement can be implemeted to the children with Down syndrome. The number of such children in Russia is around 25 thousand.

The aim is to study the conditions of negation formation in children with Down syndrome.

The sample consisted of 22 dyads of children with Down syndrome of 24-36 months old and their mothers. The research methods included: parents’ questionnaire; analysis of problematic situations; Tkacheva’s inventory Parent’s Psychological Type; Varga &Stolin Inventory of Parental Attitude; Toronto Alexithymia Scale, Bass-Darky Hostility Questionnaire, Leonhard-Schmieschek Test, Spielberger’s Test Anxiety Inventory.

Firstly, we have studied how a child expresses his or her negative reaction: whether he or she uses a gesture or a sound for “no” or reacts with the whole body. According to those results we have divided the sample into two groups and then have compared them. The research shows the connection between mother’s aggressiveness and formation of the child’s negation reaction (gesture/sound or the whole body) as well as differences in the level of alexithymia and anxiety: all the characteristics are lower in the first group.

Mothers of the children with Down syndrome demonstrate a high and a medium level of anxiety. However, the mothers of the children who expresses negation with a gesture/sound show a lower anxiety level comparing with the mothers whose children react with the whole body.
