Expert Insights

Stroke remains one of the most significant medical and social issues of our time – it is the second leading cause of death and a major driver of disability worldwide. At the same time, science continues to expand our understanding of stroke mechanisms, risk factors, treatment options, and rehabilitation. In the following five expert quotes and opinions extracted from recent scientific literature, you will find the most essential insights for understanding and navigating this complex medical issue. Each opinion is accompanied by a clarifying question or heading to help orient patients and their families.

1. What is a stroke, and why is it now classified as a neurological disorder?

"Stroke is a neurological disorder characterized by blockage of blood vessels. Clots form in the brain and interrupt blood flow, clogging arteries and causing blood vessels to break, leading to bleeding. Rupture of the arteries leading to the brain during stroke results in the sudden death of brain cells owing to a lack of oxygen. Stroke can also lead to depression and dementia… The reclassification of stroke as a neurological disorder has led to more accurate documentation of data and statistical analysis, supporting improvements in acute healthcare and acquisition of research funding for stroke."

Explanation: Today, stroke is no longer viewed solely as a vascular disease but as a neurological one, which reveals its broad range of consequences – not just physical but also cognitive and psychosocial.

2. What are the main risk factors for stroke, and which ones can we change?

"The major modifiable risk factors for stroke are hypertension, diabetes, lack of physical exercise, alcohol and drug abuse, cholesterol, diet management and genetics… Hypertension is one of the predominant risk factors for stroke… A 5–6 mm Hg reduction in BP lowered the relative risk of stroke by 42%."

Explanation: This means that controlling blood pressure, blood sugar, diet, and physical activity can significantly reduce the risk of stroke – especially in people with a family history or those who have already experienced a transient ischemic attack (TIA).

3. What do we know about the brain damage mechanisms in stroke?

"Other key events contributing to stroke pathology are inflammation, energy failure, loss of homeostasis, acidosis, increased intracellular calcium levels, excitotoxicity, free radical-mediated toxicity, cytokine-mediated cytotoxicity, complement activation, impairment of the blood–brain barrier, activation of glial cells, oxidative stress and infiltration of leukocytes."

Explanation: Stroke damage is caused not only by interrupted blood flow but also by a cascade of biochemical processes that lead to inflammation, damage to nerve cells, and impaired brain function. This is why new therapeutic targets and strategies are being explored beyond standard blood flow restoration.

4. What are the current treatment and recovery options after a stroke?

"Stroke therapy primarily focuses on restoring blood flow to the brain and treating stroke-induced neurological damage… The most effective IVT drug, recombinant tissue plasminogen activator (rt-PA, or alteplase), was developed… this drug was effective in reducing clot diameter in stroke patients within three hours of incidence. The Safe Implementation of Thrombolysis in Stroke Monitoring Study (SITS-MOST) confirmed the efficacy and safety of alteplase within the designated time frame… Rehabilitation aims to reinforce the functional independence of people affected by stroke. It includes working with patients and families to provide supportive services and post-stroke guidance after 48 h of stroke attack in stable patients. Stroke rehabilitation may involve physical, occupational, speech and/or cognitive therapy."

Explanation: The gold standard is timely blood flow restoration with thrombolysis in the first few hours after stroke, followed by comprehensive rehabilitation – not just physical but also cognitive, involving a multidisciplinary team. Family support is also crucial.

5. What’s next in stroke research and therapy?

"Advancements in stem cell technologies and genomics have led to regenerative therapy to rebuild neural networks and repair damaged neurons due to ischemic insult… Numerous natural compounds have proven to be beneficial for stroke prevention and treatment… The Utstein methodology is a process of standardizing and reporting research on out-of-hospital stroke and defining the essential elements of management tools… Optimized delivery of stroke care systems and access to rehabilitation services are the future of healthcare for stroke."

Explanation: The future lies in personalized medicine, the use of stem cells, new natural compounds, digital technologies (telemedicine), standardization of treatment, and early, individualized rehabilitation.

Q&A

1. Does stroke only affect older adults? What are the trends among younger people?

Answer: Stroke is traditionally more common in older adults, with incidence doubling after age 55. However, global data reveal a troubling trend – the share of younger people (ages 20 to 54) among all stroke cases increased from 12.9% in 1990 to 18.6% in 2016. This means stroke is increasingly affecting people in their prime, emphasizing the need for early prevention regardless of age.

2. Why are women more vulnerable to stroke, and what are the specific risks for them?

Answer: Women are at higher risk for stroke in certain age groups, particularly during pregnancy, when using hormonal contraceptives or undergoing hormone therapy, and with migraine with aura. After age 75, stroke risk increases further for women, partly due to a higher rate of atrial fibrillation. Moreover, women often delay seeking medical help when stroke symptoms appear, which can worsen outcomes.

3. Can heredity play a role in stroke? What genetic factors are known?

Answer: Yes, genetics is a significant factor. If you have a family history (a parent or close relative with stroke), your risk is higher. Specific genetic mutations (e.g., in gene 9p21) and rare inherited diseases can directly cause stroke or increase its likelihood as a complication. Genetics also influence the age of onset, gender, and racial predisposition to stroke.

4. What are the possible side effects and limitations of stroke medications?

Answer: Many drugs developed as potential stroke therapies (e.g., sodium and calcium channel blockers, antioxidants, neuroactive agents) show promising results in lab settings or animal models but often fail to demonstrate effectiveness and safety in humans. Reasons include differences between animal models and real clinical conditions, and the emergence of side effects like bleeding (with thrombolytics) or worsened brain damage (with some blockers). This means every therapy must be strictly individualized and administered under medical supervision.

5. What can I do as a patient to support better recovery after stroke?

Answer: The most important thing is to start rehabilitation as soon as your condition stabilizes (usually within 48 hours after stroke). Rehabilitation should be multidisciplinary – involving physical therapists, occupational therapists, speech-language pathologists, and psychologists. The goal is to restore as much independence as possible, improve motor and cognitive abilities, and support social reintegration. Family support, adapting the home, and consistently following the therapeutic plan significantly increase the chances of successful recovery.

Conclusion

Stroke is not a one-dimensional medical issue but a complex condition with many facets – from genetic and social factors to biochemical mechanisms and individualized recovery paths. As shown in the review by Dr. Kuriakose and Prof. Dr. Xiao, it is crucial for patients to know their risk factors, seek immediate medical help at the first signs of stroke, and actively participate in the recovery process, supported by loved ones and healthcare teams. At the same time, science continues to explore new paths for treatment and prevention, and an informed patient is the key to a better quality of life after stroke. Current research trends suggest that the future belongs to an integrated approach – combining new technologies, personalized medicine, early and individualized rehabilitation, and the broader implementation of scientific discoveries into daily clinical practice. That is why it is vital for patients and their families to have access to the latest, evidence-based information to make informed decisions and take full advantage of treatment and recovery opportunities.
