Commentary

Cerebral small vessel disease (CSVD) is a term that refers to a group of illnesses that damage the brain's tiny arteries, arterioles, venules, and capillaries. Recent tiny subcortical infarcts, lacunes, white matter hyperintensities, perivascular spaces, microbleeds, and brain atrophy are some of the neuroimaging characteristics of CSVD. Stroke, cognitive decline, dementia, mental problems, aberrant gait, and urine incontinence are the most common clinical symptoms of CSVD. There are currently no particular preventative or treatment strategies available to help with this disease. The pathogenesis, clinical features, neuroimaging, advances in CSVD therapy and prevention studies, and current CSVD treatment. Small arteries, capillaries, arterioles, and venules are frequently damaged in the advanced vascular net of brain vessels. The pathophysiology of CSVD is caused by oxidative processes, which promote the degeneration of the epithelial layer. Cerebral small vessel disorders are divided into various categories, including Binswanger's disease, leukoaraiosis, cerebral microbleeds (CMBs), and lacunar strokes. The features of CSVD and the effect of current information are presented in this study. Cerebral small vessel disease is becoming more common, with a wide range of radiological and clinical manifestations. The primary neuroimaging indicators of small vessel disease include tiny subcortical infarcts, lacunes, cerebral microbleeds, cortical microinfarcts, and white matter hyperintensity of assumed vascular origin. Increased small artery disease load is linked to an increased risk of stroke, dementia, and other neuropsychiatric symptoms.

Current research focuses on elucidating the processes behind small vessel disease development and conducting clinical trials of therapeutic medicines to alleviate the clinical symptoms of cerebral small vessel disease. Cerebral small vessel disease is widespread in the elderly and is a key risk factor for a variety of acute and chronic neurologic illnesses. Increased recognition of cerebral small vessel disease as a modifiable risk factor has the potential to reduce neurologic disease morbidity and mortality in a variety of populations in the United States and throughout the world. The prevalence of the disease rises with age, affecting approximately 5% of those aged 50 to nearly 100% of those over 90. Age, hypertension, branch atheromatous disease, cerebral amyloid angiopathy, radiation exposure, immune-mediated vasculitides, some infections, and numerous hereditary disorders are all known causes and risk factors. CSVD can be asymptomatic, but lesions can induce mild cognitive impairment, dementia, mood problems, motor and gait difficulties, and urine incontinence, depending on where they are located. Brain imaging biomarkers such as recent tiny subcortical infarcts, white matter hyperintensities, lacunes, cerebral microbleeds, increased perivascular gaps, and cerebral atrophies are used to diagnose CSVD. Advanced imaging modalities can identify illness symptoms far sooner than traditional imaging methods. Changes in white matter connection may be detected using diffusion tensor imaging, and reduced vascular reactivity can be seen using blood oxygenation level-dependent imaging. Pathogenesis is considered to start with an etiologically specific insult, with or without genetic predisposition that leads to the development of the disease.

Uncertainties about the aetiology of the disease have slowed the discovery of viable treatments. The most commonly acknowledged therapeutic strategy is to strictly regulate well-established vascular risk factors, the most significant of which is hypertension. Specific treatments may develop as a result of a greater knowledge of pathophysiology. Advanced imaging allows for the early detection of pathologic features, which allows for the prevention of disease development before symptoms appear. Cerebral small vessel disease is characterised by lacunar infarcts and white matter hyperintensities on MRI and is hereditary in around 5% of individuals. Cerebral small vessel disease and stroke are caused by a number of monogenic genetic disorders.

The goal of this systematic review is to give a framework for deciding whether molecular genetic testing should be considered in individuals with small vessel disease and stroke. Collagen type IV mutations (including PADMAL), retinal vasculopathy with cerebral leukodystrophy, Fabry disease, hereditary cerebral haemorrhage with amyloidosis and fork-head box C1 mutations is also described. Early-onset stroke is a common symptom of these monogenic diseases, as are migraines, mood swings, vascular dementia, and, in certain cases, gait abnormalities. Extra-cerebral symptoms, such as microangiopathy of the eyes and kidneys, are also seen in certain patients. Many of them have clinically identifiable syndromes.

A complete family medical history, medical history, neurological examination, and neuroimaging are all part of the investigation,which is typically complemented by specific exams such as vision, retinal abnormalities, and kidney and heart function. Molecular genetic analysis, on the other hand, is the gold standard of diagnosis. Despite its different aetiology, CSVD has neuroimaging indicators in common, such as a recent minor subcortical infarct, a lacune of supposed vascular origin, white matter hyperintensity of presumed vascular origin, perivascular space, and cerebral microbleeds. Neuroimaging indicators have radiological characteristics that can help with etiological investigation. Furthermore, the overall CSVD burden is a strong predictor of stroke occurrences, global cognitive impairment, mental problems, and later life quality in sporadic arteriosclerotic aetiology related CSVD. The goal of this study is to highlight the radiological features of CSVD indicators, as well as their clinical implications and neuroimaging interpretation for CSVD symptomatology elderly. CSVD is a significant cause of cognitive impairment and dementia, especially in the elderly, and accounts for one in every five strokes globally. One of the most prevalent kinds of cognitive impairment is post-stroke cognitive impairment (PSCI). PSCI's fundamental processes aren't fully understood. CSVD appears to play a significant role in the pathophysiology of PSCI, according to an increasing body of data. The progress in research on the connection between CSVD and PSCI is reviewed in this article.
