   FULL STORY   
   ==========================================================================   
   Regular physical activity and exercise may reduce bleeding in individuals   
   with intracerebral hemorrhage, a University of Gothenburg study shows. The   
   researchers emphasize the importance of physical activity to protect   
   the brain.   
      
   The study, published in the journal Stroke and Vascular Neurology,   
   analyzed data on 686 people treated for intracerebral hemorrhage at   
   Sahlgrenska University Hospital in Gothenburg during the years 2014   
   to 2019.   
      
   The results are based on a retrospective analysis. Causal connections   
   cannot be identified, but the findings are nonetheless clear: Those who   
   reported regular physical activity had smaller hemorrhages than those   
   who reported being inactive.   
      
   Physically active was defined as engaging in at least light physical   
   activity, such as walking, cycling, swimming, gardening, or dancing,   
   for at least four hours weekly.   
      
   50 percent less bleeding volume The main author of the study is Adam   
   Viktorisson, a PhD student in clinical neuroscience at Sahlgrenska   
   Academy, University of Gothenburg, and doctor in general practice at   
   Sahlgrenska University Hospital.   
      
   "We found that individuals who engage in regular physical activity had,   
   on average, bleeding volumes that were 50 percent smaller upon arriving   
   to the hospital. A similar connection has previously been seen in animal   
   studies, but no prior study has demonstrated this in humans."  Everyone   
   who comes to the hospital with a suspected intracerebral hemorrhage   
   undergoes a computerized tomography (CT) scan of the brain. Depending on   
   the severity of the hemorrhage, neurosurgery may be required. However,   
   in most cases, non-surgical methods and medications are used to manage   
   symptoms and promote patient recovery.   
      
   Intracerebral hemorrhage is the most dangerous type of stroke and can   
   lead to life-threatening conditions. The risk of severe consequences   
   from the hemorrhage increases with the extent of the bleeding.   
      
   "In cases of major intracerebral hemorrhages, there is a risk of   
   increased pressure within the skull that can potentially lead to fatal   
   outcomes" says Thomas Skoglund, associate professor of neurosurgery at   
   the University of Gothenburg, neurosurgeon at the University Hospital,   
   and one of the study's co- authors.   
      
   Better understanding of intracerebral hemorrhages The findings were   
   significant regardless of the location within the cerebrum.   
      
   Physically active individuals exhibited reduced bleeding in both the   
   deep regions of the brain, which are often associated with high blood   
   pressure, and the surface regions, which are linked to age-related   
   conditions like dementia.   
      
   The study creates scope for further research on intracerebral hemorrhages   
   and physical activity. Katharina Stibrant Sunnerhagen, professor of   
   rehabilitation medicine at the University of Gothenburg and senior   
   consultant physician at Sahlgrenska University Hospital, oversees   
   the study.   
      
   "We hope that our findings contribute to a deeper understanding of   
   intracerebral hemorrhages and aid in the development of more effective   
   preventive measures" she concludes.
