Central retinal artery occlusion (CRAO) is a painless ophthalmologic emergency with potential for irreversible vision loss. Similar to ischemic stroke, CRAO occurs when there is sudden obstruction of the central retinal artery, leading to ischemic injury to the retina and subsequent cell death. Continuous occlusion and ischemia of the retina progresses to permanent damage to retinal cells and loss of vision.

More than 80% of patients after a stroke have limited daily activity due to a complex polymorphic motor deficiency of various nature and severity, which leads to postural disorders (PD) [1]. Because of paresis, develops different changes in the musculoskeletal system (MSS) such as PD, restrictions of movements in the joints, impaired

Neurogenic lower urinary tract dysfunction (NLUTD) is highly prevalent in poststroke patients, leading to major impact on the quality of life (QoL) and healthcare resources. Pelvic floor muscle training (PFMT) has, over the past two decades, been recommended as first-line treatment for neurologically healthy patients with lower urinary tract symptoms (LUTS). 

Cryptogenic stroke (CS) refers to the cerebral infarcts for which no definite cause is identified after adequate diagnostic evaluation. It accounts for 10-15% of all
strokes. Most of the cryptogenic strokes are embolicappearing non-lacunar infarcts based on the radiographic pattern. 

Uromodulin (UMOD) is a glycoprotein expressed by the epithelial cells of the thick ascending limb of Henle’s loop in the kidney. Research has shown that increased uromodulin expression may be associated with lower risk of cardiovascular disease in adults.

Stroke is a common and very serious illness where timely evaluation and intervention can have dramatic effects on patient outcomes.

While TCD is an indicator of risk, not a biopsy diagnosis (such as proof of cancer), at some point in the velocity spectrum the high velocity detected by TCD reaches what many believe is an unacceptable risk of stroke.

HIV is a known risk factor for both ischemic and hemorrhagic stroke. Even with the widespread use of antiretroviral therapy, stroke incidence is higher in patients with HIV compared to non-HIV control subjects.

Stroke is the second largest cause of death worldwide, with a world annual mortality incidence of about 5.5 million people, and it is also the leading cause of disability worldwide with 50% of survivors being chronically disabled.

Joubert syndrome (JS) is a rare congenital neurodevelopmental disease which is basically a primary Ciliopathy. It’s characteristic manifestation on imaging is so called ‘molar tooth sign’ in the brainstem and cerebellum. JS can involve multiple organs, mainly including retina, kidney, bone and liver. Clinical signs of early onset JS include hypotonia, developmental delay, breathing abnormalities, and ocular motor apraxia. 

The case of a young girl with Dengue fever presenting with seizures and bilateral visual loss is presented. At the time of presentation, she had right hemiplegia and dysarthria but was not dysphasic. Fundoscopy revealed presence of macular and disc oedema in the right eye and vitreous haemorrhage in the left eye.

Brain-computer interfaces (BCIs) are a rapidly advancing field which utilizes brain activity to control external devices for a myriad of functions, including the restoration of motor function. Clinically, BCIs have been especially impactful in patients who suffer from stroke-mediated damage. However, due to the rapid advancement in the field, there is a lack of accepted standards of practice.

Stroke is a debilitating neurologic condition characterized by an interruption or complete blockage of blood flow to certain areas of the brain. While the primary injury occurs at the time of the initial ischemic event or hemorrhage, secondary injury mechanisms contribute to neuroinflammation, disruption of the blood-brain barrier (BBB), excitotoxicity, and cerebral edema in the days and hours after stroke.

Mechanical thrombectomy (MT) has established its role as a standard care of acute ischemic stroke due to large vessel occlusion (LVO). Current early stroke management guidelines have defined certain selection criteria for LVO patients undergoing MT to achieve the most benefit. However, it is still uncertain if some other LVO patients who do not meet these criteria can also benefit from MT.

Stroke is the most common cause of acquired epilepsy, with up to 30 percent of stroke survivors developing epilepsy over time. However, the mechanisms leading to neuronal hyperexcitability and epilepsy in stroke survivors are not fully understood. In a recently published work, we demonstrate that ischemic stroke induces homeostatic plasticity regulation in the surviving neurons in the peri-stroke area.
