We describe a patient with seizures following a stroke in whom on ictal 99mTc-HMPAO single-photon emission computed tomography demonstrated cerebral blood flow "schistotaxis", i.e., focal hyperaemia corresponding to an epileptogenic focus together with an extensive hypoperfused area in the same hemisphere. This phenomenon may have been caused by haemodynamic alternation and a remote transneural effect during the seizures.

Non-Traumatic Intracranial Hemorrhage and Risk of Incident Dementia in U.S. Medicare Beneficiaries.

To study the risk of incident dementia after a non-traumatic intracranial hemorrhage in a diverse US population, and evaluate if this risk is different for the subtypes of intracranial hemorrhage. We performed a retrospective cohort study using both inpatient and outpatient claims data on Medicare beneficiaries between January 1, 2008 and December 31, 2018. The exposure was a new diagnosis of non-traumatic intracranial hemorrhage, defined as a composite of intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and subdural hemorrhage (SDH).

There is limited data on ultra-early hematoma growth dynamics and its clinical relevance in primary intracerebral hemorrhage (ICH). We aimed to estimate the incidence of hematoma expansion (HE) within the hyperacute period of ICH, describe hematoma dynamics over time, investigate the associations between ultra-early HE and clinical outcomes after ICH, and assess the effect of tranexamic acid on ultra-early HE. We performed a planned secondary analysis of the STOP-MSU international multicenter randomized controlled trial.

Purpose: We aimed to verify the impact of functional remediation (FR) on serum brain-derived neurotrophic factor (BDNF) and tyrosine kinase receptor B (TrkB) levels, to explore the biomechanism of FR intervention in patients with euthymic bipolar disorder (BD).
Patients And Methods: This is a randomized controlled, 12-week intervention study with participants randomized into the FR group (n=39) and the treatment as usual group (TAU, n=42) at the 1∶1 ratio. 17-Hamilton Depression Rating Scale-17 (HDRS-17), Young Mania Rating Scale (YMRS), and Measurement and Treatment Research to Improve Cognition in Schizophrenia (MATRICS) Consensus Cognitive Battery (MCCB) were used to assess affective symptoms and cognitive functioning both at baseline and week 12, respectively.

Introduction: Resting state-fMRI, provides a sensitive method for detecting changes in brain functional integrity, both with respect to regional oxygenated blood flow and whole network connectivity. The primary goal of this report was to examine alterations in functional connectivity in collegiate American football players after a season of repetitive head impact exposure.
Methods: Collegiate football players completed a rs-fMRI at pre-season and 1 week into post-season.

Intracerebral hemorrhage (ICH) is the most common subtype of hemorrhagic stroke causing significant morbidity and mortality. Previously clinical treatments for ICH have largely been based on a single pathophysiological perspective, and there remains a lack of curative interventions. Following the rupture of cerebral blood vessels, blood metabolites activate resident immune cells such as microglia and astrocytes, and infiltrate peripheral immune cells, leading to the release of a series of inflammatory mediators.
