Cardiac arrest survivors experience ongoing stress from cognitive changes and fear of decline, while their caregivers feel burdened by supporting them, according to a 2025 qualitative study of 19 survivor-caregiver pairs. Both groups successfully use coping strategies including peer support, exercise, and organizational tools, and they want more education about nutrition, emotional management, and how cardiac arrest affects the brain.
When someone survives a cardiac arrest, their brain can be affected in ways that create stress for both them and their family caregivers. According to Gram Research analysis, a new study talked to 19 cardiac arrest survivors and their caregivers to understand what worries them most and how they cope. The survivors reported memory problems and fear of getting worse, while caregivers felt stressed from helping. The good news? People are already using helpful strategies like exercise, support groups, and organizational tools. Researchers found that survivors and caregivers want more information about nutrition, managing emotions, and understanding how cardiac arrest affects the brain.
Key Statistics
A 2025 qualitative study of 19 cardiac arrest survivor-caregiver pairs found that survivors reported cognitive changes, fear of further decline, and concerns about caregiver stress as primary sources of brain health-related stress.
According to research reviewed by Gram, cardiac arrest survivors and caregivers reported using multiple coping strategies including peer support, professional mental health treatment, physical activity, and compensation strategies like organizational aids and task delegation.
A 2025 study of 19 dyads found that survivors and caregivers specifically requested additional program content on nutrition and diet, managing emotional distress, and psychoeducation about cardiac arrest’s impact on the brain.
Research from 19 cardiac arrest survivor-caregiver pairs conducted between September 2024 and May 2025 showed that both survivors and caregivers endorsed a proposed brain health lifestyle intervention program and provided recommendations for enhancement.
The Quick Take
- What they studied: What stresses cardiac arrest survivors and their family caregivers experience related to brain health, and what strategies help them cope
- Who participated: 19 pairs of cardiac arrest survivors and their caregivers (9 pairs in focus groups, 10 pairs in interviews) recruited between September 2024 and May 2025, intentionally including people from different racial and ethnic backgrounds
- Key finding: Survivors experience cognitive changes and fear of decline, while caregivers feel stressed from supporting them. Both groups use coping strategies like peer support, exercise, and organizational tools, and want more education about nutrition and emotional health
- What it means for you: If you’ve survived cardiac arrest or care for someone who has, you’re not alone in experiencing brain-related challenges. Strategies like joining support groups, staying physically active, and using organizational tools can help. Talk to your doctor about getting more information on nutrition and managing emotions after cardiac arrest
The Research Details
Researchers conducted focus groups and one-on-one interviews with 19 pairs of cardiac arrest survivors and their caregivers. They asked open-ended questions to understand what stresses these people face related to brain health and how they manage. The researchers specifically recruited people from different racial and ethnic backgrounds to ensure diverse perspectives. They then carefully reviewed all the conversations to find common themes and patterns in what people said.
This qualitative approach—where researchers listen to people’s stories rather than measure numbers—is valuable for understanding complex, personal experiences. It allowed survivors and caregivers to describe their real-world challenges and solutions in their own words, which numbers alone couldn’t capture.
The study was conducted between September 2024 and May 2025, with participants recruited through the Sudden Cardiac Arrest Foundation and healthcare providers. This ensured they were talking to people with actual experience living with cardiac arrest recovery.
Understanding what cardiac arrest survivors and caregivers actually experience is crucial for designing helpful programs and support. Rather than guessing what problems matter most, researchers asked the people living with these challenges directly. This helps ensure that future interventions address real needs and include strategies that people already find helpful.
This is a qualitative study, which means it provides rich, detailed information about people’s experiences but involves a smaller number of participants than large statistical studies. The sample size of 19 dyads is appropriate for this type of in-depth research. The researchers intentionally included diverse racial and ethnic backgrounds, which strengthens the findings. The study was recently conducted (2024-2025), so findings reflect current experiences. However, results may not apply equally to all cardiac arrest survivors, and the findings need testing in larger studies to confirm their broader relevance
What the Results Show
Cardiac arrest survivors reported three main sources of stress related to brain health: experiencing cognitive changes (like memory problems or difficulty concentrating), fear that their brain problems would get worse, and worry about the stress their condition places on their caregivers. These concerns were ongoing and affected daily life.
Caregivers experienced their own stressors, primarily related to supporting the survivor’s recovery and managing the emotional burden of caregiving. They worried about the survivor’s cognitive decline and felt responsible for helping them manage these challenges.
Despite these stressors, both survivors and caregivers reported using multiple coping strategies that helped them manage. These included connecting with peer support groups (talking to other survivors and caregivers), getting professional mental health treatment, practicing acceptance of their situation, and staying physically active. For daily challenges, they used compensation strategies like having the caregiver take on more tasks, using organizational tools (like calendars or reminder apps), using visual aids, and pacing activities to avoid overwhelming the survivor.
When researchers presented a proposed brain health lifestyle program to the participants, they strongly supported the idea. Survivors and caregivers endorsed the program’s content and made specific recommendations for additions. They particularly wanted more information on three topics: nutrition and diet’s role in brain health, strategies for managing emotional distress, and education about how cardiac arrest specifically affects the brain. These recommendations suggest that survivors and caregivers recognize the importance of these areas but feel they lack adequate information.
This study fills an important gap in research. While previous studies have examined cognitive problems after cardiac arrest, few have directly asked survivors and caregivers what they experience and what they need. By including both survivors and caregivers as partners in understanding the problem, this research provides a more complete picture than studies focusing on survivors alone. The emphasis on coping and compensation strategies aligns with research showing that people develop practical solutions to manage health challenges, though these strategies deserve more formal study and support.
The study included only 19 pairs of survivors and caregivers, which is a small number. This means findings may not apply to all cardiac arrest survivors—for example, survivors with more severe cognitive problems or those without family caregivers may have different experiences. The study relied on people’s memories and self-reports, which can be affected by mood and perspective. Additionally, because participants were recruited through specific organizations and providers, the sample may not represent all cardiac arrest survivors. The study was conducted in 2024-2025, so long-term outcomes beyond this timeframe are unknown. Finally, while the study intentionally included diverse racial and ethnic backgrounds, the overall sample size limits how much we can understand differences between groups
The Bottom Line
If you’re a cardiac arrest survivor: Stay physically active, connect with peer support groups, consider professional mental health support, and talk with your healthcare team about nutrition and brain health. If you’re a caregiver: Seek support through caregiver groups, consider your own mental health needs, and use organizational tools to manage tasks. Both survivors and caregivers should ask their doctors for education about how cardiac arrest affects the brain and strategies for managing emotional challenges. Confidence level: Moderate—these strategies are supported by this research and align with general health recommendations, but larger studies are needed to confirm effectiveness
This research is most relevant to cardiac arrest survivors experiencing cognitive changes and their family caregivers. It’s also important for healthcare providers, social workers, and program designers creating support services for this population. People who have experienced other types of brain injury or cognitive decline may find some insights relevant. This research is less directly applicable to people who haven’t experienced cardiac arrest or those with only mild or no cognitive effects
Cognitive and emotional recovery after cardiac arrest is a long-term process. Some people see improvements in the first weeks to months, while others experience ongoing challenges. Coping strategies and support typically help people manage stress and maintain quality of life within weeks to months of starting them. However, expecting complete recovery of all cognitive function may not be realistic for everyone. Work with your healthcare team to set realistic goals and monitor progress over time
