Motor functioning during early recovery after childhood Arterial ischemic stroke is associated with intellectual abilities.
Appl Neuropsychol Child
December 2024
Division of Neurology, The Hospital for Sick Children, Toronto, Ontario, Canada.
Article Synopsis
- Motor impairments are common after childhood arterial ischemic stroke (C-AIS), affecting the understanding of how these impairments relate to intellectual abilities in children.
- A study of 34 children with C-AIS found that motor functioning in early recovery significantly correlates with various intellectual skills, including verbal and perceptual reasoning abilities.
- The results suggest that early motor deficits may influence intellectual development due to neuroplastic changes after injury, while motor functions assessed closer to testing reflect recovery and improvement potentially aided by interventions.
Recurrent Falls as the Only Clinical Sign of Cortical-Subcortical Myoclonus: A Case Report.

Some authors use the term cortical-subcortical myoclonus to identify a specific type of myoclonus, which differs from classical cortical myoclonus in that the abnormal neuronal activity spreads between the cortical and subcortical circuits, producing diffuse excitation. The EEG shows generalized spike-and-wave discharges that correlate with the myoclonic jerks. We report the case of a 79-year-old patient with a history of right thalamic deep hemorrhagic stroke, with favorable evolution.

Child Health Evaluative Sciences Program, Hospital for Sick Children Research Institute, Toronto, Canada (G.D.).
Article Synopsis
- The study investigates how the age at which a pediatric patient suffers an arterial ischemic stroke affects their long-term neurological outcomes and how this interacts with the location and extent of the brain injury.
- Conducted at the Hospital for Sick Children in Toronto, the research followed 285 children diagnosed with strokes from 1996 to 2016 and used various models to analyze outcomes based on age groups and infarct characteristics.
- Results show that older children have worse outcomes, particularly when the stroke affects multiple areas of the brain, with significant differences in outcomes noted between age-at-stroke and specific brain regions impacted.
An ANN models cortical-subcortical interaction during post-stroke recovery of finger dexterity.

Finger dexterity, and finger individuation in particular, is crucial for human movement, and disruptions due to brain injury can significantly impact quality of life. Understanding the neurological mechanisms responsible for recovery is vital for effective neurorehabilitation. This study explores the role of two key pathways in finger individuation: the corticospinal (CS) tract from the primary motor cortex and premotor areas, and the subcortical reticulospinal (RS) tract from the brainstem.
