Depression's correlation with stroke risk
A new study sheds light on the intricate relationship between depression and stroke risk, suggesting that addressing both mental health and cardiovascular health could be key to reducing stroke risk.
The research, involving nearly 27,000 participants from the INTERSTROKE study spanning 32 countries, found that symptoms of depression can increase the risk of stroke. According to the study, people with symptoms of depression before a stroke had a 46% higher chance of stroke compared to those without depression.
The study's lead author, Robert P. Murphy MBBS, stated that the findings provide deeper insights into how depressive symptoms contribute to stroke.
Depression, a persistent feeling of sadness that interferes with daily life and takes joy from pleasurable experiences, is linked to an increased risk of various serious ailments, including cancer, diabetes, hypertension, and stroke.
Researchers have also discovered that depression can influence physical capability and quality of life in stroke survivors, with hypertension playing a significant moderating role in these effects.
In a bid to lower stroke risk, a two-pronged approach is suggested, focusing on both the health of blood vessels and mood.
Omega-3 fatty acids, such as those found in fatty fish, fish oil, or krill oil, may protect the brain from stroke by counteracting inflammation in blood vessels. Clinical trials report that omega-3 supplementation can significantly reduce depressive symptoms, sometimes with effects comparable to antidepressants.
The process, known as resolution of inflammation, is believed to be how omega-3s protect the brain from stroke. A 2015 study found that taking omega-3 supplements improved mood and lowered cortisol levels in participants with late-life depression.
Phosphatidylserine, a phospholipid vital for neuronal membrane integrity and cognitive function, may also support brain health and potentially aid in cognitive recovery post-stroke and mitigating depressive symptoms through improved neuronal function. However, more specific evidence would be required to confirm this.
In conclusion, depression increases stroke risk by elevating cardiovascular risk factors and inflammation. Omega-3 fatty acids can reduce depressive symptoms and inflammation, which may lower stroke risk indirectly. Phosphatidylserine may support brain cell function and cognitive health, potentially complementing interventions aimed at stroke recovery and depression.
Thus, supplementing with omega-3s and possibly phosphatidylserine can be part of a multi-faceted approach to reduce depression-related stroke risk, primarily by improving mood, decreasing inflammation, and supporting neuronal health. Additionally, passive stretching can help keep blood vessels at their best and blood flowing smoothly, decreasing arterial stiffness in as little as 12 weeks.
Physicians should look for symptoms of depression to help guide health initiatives focused on stroke prevention. By addressing both mental health and cardiovascular health, we can work towards reducing the number of strokes and improving the quality of life for those affected.
The findings of the study suggest that addressing both mental health and cardiovascular health, including inflammation, could be essential in reducing stroke risk. Omega-3 fatty acids, known to counteract inflammation in blood vessels, may indirectly lower stroke risk by reducing depressive symptoms, as reported in clinical trials.
