The American Stroke Association has published research that highlights the significant role of nontraditional risk factors in unexplained strokes among young adults. According to a study published in Stroke, the peer-reviewed scientific journal, adults under 50 years old have more than double the risk of having a stroke from migraine or other nontraditional stroke risk factors compared to traditional risks such as high blood pressure.

Previous research indicates that the rate of ischemic (clot-caused) strokes among adults aged 18-49 is increasing, propelled by a corresponding rise in cryptogenic strokes (strokes of unknown cause) in adults without traditional risk factors. Up to half of all ischemic strokes in younger adults are of unknown causes and more common in women.

Researchers analyzed data from over 1,000 European adults aged 18-49, with a median age of 41 years. Half of the participants had experienced a cryptogenic ischemic stroke, while half had no history of stroke. The study examined the associations of 12 traditional risk factors, 10 nontraditional risk factors, and five risk factors specific to women.

The analysis found that:

* Non-traditional risk factors contributed significantly to unexplained strokes in younger adults.
* Migraine headaches emerged as one of the leading risk factors for stroke development in this age group.
* The study’s results should inform healthcare professionals to develop a more tailored approach to risk factor assessment and management.

Lead study author Jukka Putaala emphasized the importance of careful and routine assessment of both traditional and nontraditional risk factors in younger people, as well as screening after they have had a stroke to prevent future strokes. American Heart Association chair Tracy E. Madsen noted that recognizing specific risks that affect women and those not commonly seen could change our approach to screening for these risks and educating patients throughout their lives.

The study’s limitations include being an observational study, which means it was a review and analysis of existing health data on patients enrolled in another trial or database, and the reliance on patient-reported risk factors. The findings may not be applicable to other populations due to the predominantly white European participant pool.

Overall, this research highlights the critical need for healthcare professionals to consider nontraditional risk factors, especially migraine headaches, when assessing stroke risk in younger adults, particularly women.

Discovery Uncovers Common Protein Link Between Parkinson’s Disease and Skin Cancer

A groundbreaking study has revealed that a small protein called alpha-synuclein plays a crucial role in both neurodegenerative diseases like Parkinson’s and skin cancers such as melanoma. The research, led by Oregon Health & Science University (OHSU), suggests new avenues for drug development to reduce the risk of developing both conditions by targeting this protein.

The study found that alpha-synuclein helps to repair DNA double-strand breaks in brain cells known as neurons, which is essential for preventing cell death. However, in melanoma cells, alpha-synuclein does its job too well, allowing cancerous cells to proliferate uncontrollably. This contrasts with Parkinson’s disease, where an overabundance of alpha-synuclein leads to cellular death.

In melanomas, alpha-synuclein remains within the cell’s nucleus and recruits a different type of protein called 53BP1 to repair DNA double-strand breaks. This can lead to runaway cellular replication – cancer.

Senior author Vivek Unni, M.D., Ph.D., an associate professor of neurology in the OHSU School of Medicine, said that developing drugs targeting alpha-synuclein may be useful in treating both Parkinson’s disease and melanoma. Alternatively, researchers are exploring other avenues to boost the recruitment of 53BP1 protein as a possible treatment for Parkinson’s.

The study provides new insights into the link between Parkinson’s disease and melanoma, offering potential therapeutic targets in melanoma focused on reducing alpha-synuclein-mediated nucleolar double-strand break repair. The research was supported by various institutions, including the National Institute on Aging, National Institute of Neurological Disorders & Stroke, and National Cancer Center.

This discovery has significant implications for the development of novel treatments for both neurodegenerative diseases and skin cancers, highlighting the importance of further research into the role of alpha-synuclein in these conditions.

Stroke Deaths on the Rise: Understanding Racial Disparities and Shifts in Care

A recent study has highlighted disturbing trends in ischemic stroke mortality rates in the United States over the past two decades. The research, published in PLOS One, found that nearly three in 10 deaths from this type of stroke occur at home, with significant increases among racial minorities and rural residents.

Stroke remains a leading cause of death in the US, with around 140,000 people dying from it each year. Understanding the trends behind these fatalities is crucial for improving end-of-life care and addressing healthcare inequities.

The study analyzed data from the Centers for Disease Control and Prevention’s Wide-ranging Online Data for Epidemiologic Research (CDC WONDER) database, which included over 237,000 recorded ischemic stroke deaths between 1999 and 2020. The results showed that age-adjusted mortality rates have increased across all urbanization levels since 2009, with the most pronounced rises in non-metropolitan areas.

A striking shift has also been observed in where people are dying from ischemic stroke – more are now passing away at home instead of in hospitals or other medical facilities. From 1999 to 2020, the percentage of at-home deaths increased from 8.44% to 29.31%. This trend is particularly concerning among Black/African American individuals and those living in rural areas.

The authors note that it’s unclear whether this shift towards dying at home is due to personal preference or a lack of access to hospital-based or specialized care. They conclude that rising stroke mortality and increased reliance on home-based end-of-life care call for new assessments of the factors impacting stroke outcomes.

This study highlights the need for targeted health policy interventions to address disparities in stroke care. By understanding these trends, policymakers can work towards improving access to care and reducing healthcare inequities, ultimately saving lives.
