Background: The association between left hemisphere stroke and acute speech and language impairment is well documented in adults. However, little is known about this association in childhood arterial ischemic stroke. Here we examined potential predictors of acute speech (dysarthria and apraxia) and language impairments after childhood arterial ischemic stroke, including site of lesion.Methods: Children with radiologically confirmed acute arterial ischemic stroke, admitted to a tertiary pediatric hospital from 2004 to 2012, were identified from an institutional registry. We examined the prevalence of dysarthria, apraxia, and language impairment within two weeks of the stroke. Associations with age at stroke event, lesion side (left, right, or bilateral), and arterial territory affected (anterior, posterior, or both) were assessed using logistic regression.Results: Sixty-two children with mean age eight years (range three to 17 years) were identified. Strokes were located in the left (32%), right (44%), or both hemispheres (24%). Dysarthria (74%) and language impairment (50%) were frequent. Verbal dyspraxia was less common (11%). There was little evidence that variables of interest, including site of lesion, were significantly associated with increased odds of dysarthria or language impairment (all P > 0.49).Conclusions: Regardless of age, children are at high risk of communication disorders after stroke. Unlike adults, left hemisphere stroke was not associated with either speech or language impairment in our cohort, suggesting there may be bihemispheric contribution to language function. Future studies are needed to examine whether the predictors examined here determine long-term outcomes. [ABSTRACT FROM AUTHOR]

Intervention at the earliest illness stage, in ultra or clinical high-risk individuals, or indicated prevention, currently represents the most promising strategy to ameliorate, delay or prevent psychosis. We review the current state of evidence and conduct a broad-spectrum meta-analysis of various outcomes: transition to psychosis, attenuated positive and negative psychotic symptoms, mania, depression, anxiety, general psychopathology, symptom-related distress, functioning, quality of life, and treatment acceptability. 26 randomized controlled trials were included. Meta-analytically pooled interventions reduced transition rate (risk ratio [RR] = 0.57, 95%CI 0.41–0.81) and attenuated positive psychotic symptoms at 12-months (standardized mean difference = −0.15, 95%CI = -0.28–-0.01). When stratified by intervention type (pharmacological, psychological), only the pooled effect of psychological interventions on transition rate was significant. Cognitive behavioral therapy (CBT) was associated with a reduction in incidence at 12-months (RR = 0.52, 95%CI = 0.33–0.82) and 18–48-months (RR = 0.60, 95%CI = 0.42–0.84), but not 6-months. Findings at 12-months and 18–48-months were robust in sensitivity and subgroup analyses. All other outcomes were non-significant. To date, effects of trialed treatments are specific to transition and, a lesser extent, attenuated positive symptoms, highlighting the future need to target other symptom domains and functional outcomes. Sound evidence supports CBT in reducing transition and the value of intervening at this illness stage. Research Registry ID: reviewregistry907. • This meta-analysis of 26 randomized controlled trials (N = 2351) examined the efficacy of interventions for ultra-high risk for psychosis. • Psychological interventions pooled, and cognitive behavioral, reduced transition to psychosis at 12-months and up to 4 years follow-up. • Treatments also had a small effect on attenuated positive psychotic symptoms at 12-months. • It is feasible to prevent or delay the onset of psychotic disorders through preventive interventions that are safe and effective. • A broad range of head-to-head treatment studies that target the full spectrum of clinical and functional outcomes is needed.

Objective: To examine predictors of speech disorder resolution versus persistence at age 7 years in children with speech errors at age 4 years.Study Design: Participants were drawn from a longitudinal, community cohort. Assessment at age 4 years (N?=?1494) identified children with speech errors. Reassessment at age 7 years allowed categorization into resolved or persistent categories. Logistic regression examined predictors of speech outcome, including family history, sex, socioeconomic status, nonverbal intelligence, and speech error type (delay vs disorder).Results: At age 7 years, persistent errors were seen in over 40% of children who had errors at age 4 years. Speech symptomatology was the only significant predictor of outcome (P?=?.02). Children with disordered errors at age 4 years were twice as likely to have poor speech outcomes at age 7 years compared with those with delayed errors.Conclusions: Children with speech delay at age 4 years seem more likely to resolve, and this might justify a "watch and wait" approach. In contrast, those with speech disorder at age 4 years appear to be at greater risk for persistent difficulties, and could be prioritized for therapy to offset long-term impacts.

Highlights • The communication profile in Klinefelter syndrome is variable. • Language, literacy and social-pragmatic deficits are common. • More notable deficits in older boys, relating to increased academic/social demands. • Persistent phonological errors in speech production is a novel finding. Abstract Background Speech and language deficits are frequent in males with Klinefelter syndrome (KS), yet the research base is slim and specific strengths and deficits in communication have not been well characterised. Nor have studies examined communication abilities across a wide age-range from infancy to adolescence. Objective To characterise communication in children and adolescents with KS. Method Twenty-six males, aged 1;1–17;4 years, took part in the study. Oromotor, speech, language, literacy and pragmatic abilities were assessed. Results Communication impairment was seen in 92% of cases (24/26), with salient findings being impairments in social-pragmatic language (15/18; 83%), language-memory (12/15; 80%) and literacy (13/17; 76%). Mild to severe receptive and expressive language deficits were common (16/23; 70%), although performance was varied across linguistic domains of semantics, syntax, and morphology. Oromotor impairment (21/21; 100%) and speech impairments were evident from preschool through to adolescence. Whilst speech was highly intelligible (22/26; 85%), articulation errors (12/26; 46%), phonological delay (12/26; 46%), phonological disorder (5/26; 19%) and dysarthria (2/23 8.7%) were observed. Other atypical, yet mild, speech features were noted such as hyponasality (16/23; 70%). Conclusions Language, literacy and social-pragmatic deficits are common in KS. Data suggested a trend for more notable deficits with age and increasing academic and social demands. We added novel data on the nature of speech production deficits, including persistent phonological errors in a number of cases. Earlier detection and intervention of phonological errors may reduce the risk for later language and literacy challenges and optimise academic, and ultimately social and behavioural difficulties later in life.
