To better understand the natural history of poststroke apathy, the authors tested 96 patients undergoing acute rehabilitation for stroke using the Apathy Inventory. A total of 28% of patients had apathy. Their Apathy Inventory scores improved a mean of 1 point by week 2 and 2 points by week 3, with the majority of patients remaining apathetic at discharge. Apathy severity correlated with aphasia, weakness, and impaired cognition but did not correlate with depression. These findings suggest that acute rehabilitation is an optimal setting for clinical trials for poststroke apathy, because apathy is associated with poor outcomes and shows only a small degree of spontaneous improvement.

There has been a lack of clarity about the mechanisms of widespread network dysfunctions after stroke. This study aimed to reveal dynamic functional network alternations following stroke based on lesion and brain perfusion. We prospectively enrolled 125 acute ischaemic stroke patients (25 were transient ischemic attack (TIA) patients) and 49 healthy controls with assessed the severity of their depression, anxiety, fatigue, and apathy.

Article Synopsis
- Approximately 50 million people live with dementia worldwide, a number expected to triple by 2050, with vascular contributions affecting around 20 million people currently.
- Vascular Cognitive Impairment (VCI) includes a range of cognitive decline due to cerebrovascular issues, often co-occurring with Alzheimer's disease, yet remains a neglected area in research with limited treatment options.
- Management focuses on preventing strokes and controlling vascular risk factors, while ongoing research aims to introduce new treatment strategies and emphasizes the need for cognitive assessments in cardiovascular studies.

Purpose: Post-stroke (PS) cognitive impairment (CI) is frequent and its devastating functional and vital consequences are well known. Despite recent guidelines, they are still largely neglected. A large number of recent studies have re-examined the epidemiology, diagnosis, imaging determinants and management of PSCI.

Problem-solving therapy (PST) is a potential psychological intervention aimed at preventing and treating psychological issues in stroke patients, although its efficacy is not clearly established. This systematic review assessed the effectiveness of PST in improving mental health, functioning, quality of life, and mortality in this population. Six databases were searched for literature indexed through March 2024, including the Cochrane Library, PubMed, Scopus, CINAHL, NeuroBITE, and OTseeker.
