Irritability in stroke: a protocol for a prospective study.
Front Neurol
December 2024
Department of Medicine and Therapeutics, The Chinese University of Hong Kong, Hong Kong, Hong Kong SAR, China.
Background: Poststroke irritability (PSI) is common among stroke survivors and can lead to a poor quality of life, difficulties in social interactions, criticism from caregivers, and caregiver stress. The planned study will evaluate the clinical, neuropsychological, and magnetic resonance imaging (MRI) correlates of PSI in a cohort of stroke survivors. In addition, the study will examine the 15-month progression of PSI.

Medicine (Baltimore)
December 2024
Department of Neurology, Shaoxing Second Hospital, Shaoxing, Zhejiang, China.
Rationale: Bilateral thalamic infarction is a rare type of posterior circulation stroke, and it often presents with a reduced level of consciousness in the elderly. Arteriosclerosis is the primary etiology of bilateral thalamic infarction, including conditions such as native vessel stenosis or arterial-to-arterial embolism. Cardiogenic or paradoxical embolism can also lead to thrombosis of the perforator branches innervating the thalamus, and these emboli tend to disintegrate and lead to multiple lesions, even in elderly patients.

Central post-stroke pain (CPSP) is a chronic neuropathic pain syndrome that commonly occurs after cerebral stroke, and it severely impairs the daily activities of stroke patients. A number of fundamental and clinical studies support the theory that CPSP is mainly caused by ischemic and hemorrhagic injury of the spinal-thalamic-cortical neural pathway. However, the underlying reasons of CPSP genesis and development are far from clear.

Quant Imaging Med Surg
December 2024
Department of Radiology, First Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Background: The lenticulostriate artery-neural complex (LNC), which includes the lenticulostriate artery (LSA) and surrounding neural structure, is a new concept proposed by neurologists and plays a pivotal role in hypertension-induced stroke. Conventional low-magnitude magnetic resonance imaging (MRI) has not been successfully used to reveal the microstructural changes of the LNC. This study aimed to evaluate the microstructural changes of the LNC in patients with prestroke hypertension using 7-Tesla (7-T) MRI and to identify the potential MRI biomarkers for monitoring hypertension-related neurological disorders.

Department of Neurology, Nakamura Memorial Hospital.
The patient was a 69-year-old right-handed woman. She had sensory aphasia, and the brain MRI revealed a subacute phase hemorrhage in the left subcortical temporal lobe. We speculated that the patient had post-ictal aphasia due to symptomatic epileptic seizures associated with cerebral hemorrhage.
