Importance: Individuals with sickle cell disease (SCD) are at heightened risk of poor neurocognitive and academic outcomes. The relationship between fine motor skills and academic outcomes is not well understood.

Objective: To compare the fine motor skills of individuals with SCD with normative expectations, test whether demographic and medical factors are associated with fine motor performance, and determine the impact of fine motor performance on academic performance.

Design: Cross-sectional.

Setting: St. Jude Children's Research Hospital.

Participants: Individuals with SCD (N = 376; ages 8-24 yr).

Outcomes And Measures: Fine motor outcomes included visual-motor integration, manual dexterity, and graphomotor speed. Academic outcomes included math fluency and word reading. Demographic and medical variables were obtained via medical records and interviews.

Results: Compared with normative expectations, the performance of individuals with SCD on all fine motor measures was lower than expected. Male sex, lower socioeconomic status, and lower oxygen saturation was associated with slower graphomotor speed. Lower socioeconomic status and older age were associated with lower visual-motor integration scores. Performance on all fine motor measures was positively associated with math fluency and word reading.

Conclusions And Relevance: Individuals with SCD exhibited poorer than expected fine motor skills across multiple motor domains, and these deficits were associated with poorer academic outcomes. Early referral to intervention services for fine motor skills may facilitate improved academic outcomes for individuals with SCD. Plain-Language Summary: This study had three objectives: (1) Compare the fine motor skills of people with sickle cell disease (SCD) with normative expectations, (2) test whether demographic and medical factors are associated with fine motor performance, and (3) determine the impact of fine motor performance on academic performance. We found that SCD is a risk factor for lower than expected fine motor performance across multiple fine motor domains and that these deficits also affect functional academic skills.

Background: A 69-year-old retired businessman, born in 1954, with 12 years of education, had been participating in cognitive enhancement sessions for the past 5 years. His medical history included two ischemic strokes, left hemiplegia, as well as disturbances in the left visual field. This study aimed to examine the individual's cognitive performance over the course of these 5 years, including the COVID-19 pandemic period.

Background: Children with Autism exhibit impairment of fine motor co-ordination and sensory sensibilities and hence can directly affect the toothbrushing leading to poor oral hygiene.

Aim: This current systematic review and meta-analysis (SRMA) aims to evaluate the effectiveness of Video-based intervention of toothbrush training over other methods on improvement of oral hygiene in children with autism spectrum disorders (ASD) MATERIALS AND METHODS: Prospero no: (CRD42023450168). 'PubMed', 'Cochrane', 'Ovid' databases were searched from 1 January 1980 to 1 August 2023 using pre-defined search strategy.

Background: Those with neurological disorders like cerebral palsy (CP) may experience an altered impact of social determinates of health on child functioning and well-being. We investigated the relationship between relative social advantage and medical and functional outcomes in a large cohort of children, adolescents and young adults with CP (n = 1269, aged 2-84 years).

Methods: We extracted data from the Cerebral Palsy Research Registry and dichotomized a range of independent factors (income, ethnicity and race) into advantaged and disadvantaged/vulnerable and a range of medical and functional outcomes (gross motor, manual ability, behaviour, breathing, nutritional intake, hearing, seizures, language and vision) and computed odds ratios using logistic regression.

Children with attention deficit hyperactivity disorder (ADHD) exhibit various degrees of motor and cognitive impairments in fine and gross motor skills. These impairments impact social functioning, while also hindering academic achievement, self-esteem, and participation. Specifically, motor impairments are not fully addressed by current therapies.
