   A team of scientists at the Danish Dementia Research Center in Copenhagen,   
   Denmark have discovered that regular physical activity can provide patients   
   with Alzheimer's with considerable relief regarding the neuropsychiatric   
   symptoms of the disease. (

   People suffering from Alzheimer's disease may benefit from regular exercise in   
   terms of lowering the levels of dementia and memory loss, according to new   
   research presented at the Alzheimer's Association International Conference   
   (AAIC) in Washington, DC.   
      
   A new clinical study performed by researchers from Denmark suggests that   
   physical exercise can provide patients with Alzheimer's and other forms of   
   dementias with various health benefits that could help improve the quality of   
   their lives and extend their    
   independence.   
      
   Earlier studies have presented evidence that regular exercise can lower the   
   risk of suffering cognitive decline and even lower the risk of several mental   
   impairments, such as Alzheimer's disease and dementia. Some studies have also   
   pointed to an    
   improvement of cognition in healthy older people as a result of physical   
   activity.   
      
   For a long time, it remained largely unknown for scientists whether regular   
   physical activity among Alzheimer's patients could help improve symptoms of   
   the disease, or if it could provide them with a positive impact regarding   
   their brain's physical    
   changes as a result of the disease.   
      
      
   The study presented at the AAIC offered findings that show the benefits of   
   physical activity to people who already have Alzheimer's disease.   
      
      
   Researchers at the Danish Dementia Research Center (DDRC) in Copenhagen   
   provided the results of their Danish ADEX Study, which featured a large,   
   controlled study of the benefits of high and moderate intensity workout for   
   Danish people diagnosed with mild    
   to moderate forms of Alzheimer's.   
      
   In their study, 200 Alzheimer's patients, between 50 to 90 years old, were   
   assigned randomly to either a supervised program of aerobic exercise or a to a   
   control group.   
      
   The exercise program featured thrice-a-week 60-minute sessions for 16 weeks   
   and monitored by experienced physiotherapists. The control group, on the other   
   hand, featured a standard program with no additional exercise involved.   
      
   After undergoing a four-week adaptive exercise regimen, participants in the   
   exercise group were asked to perform aerobic exercise at a set intensity of 70   
   to 80 percent of the maximum heart rate for the remainder of the program.   
      
   By the end of the study, the researchers discovered that participants who were   
   part of the exercise group experienced relatively fewer neuropsychiatric   
   symptoms which include depression, anxiety and irritability, compared to those   
   who belonged to the    
   control group.   
      
   While members of the control group were shown to have deteriorated in terms of   
   their psychiatric symptoms, those of the intervention group experienced a   
   slight improvement.   
      
   Another finding showed that patients who took part in more than 80 percent of   
   the exercise sessions and were able to raise their regular heart rate to   
   beyond 70 percent of their maximum rate experienced improvements on their   
   attention and mental speed.   
      
   Those who participated in the physical activity program became more physically   
   fit and improved their physical function and ability to perform dual tasks.   
   They also showed an improvement in their self-efficacy.   
      
   DDRC researcher Dr. Steen Hasselbalch said that symptoms of Alzheimer's   
   disease, such as depression, anxiety and irritability, have been the cause of   
   significant distress for patients and their caregivers.   
      
   He explained that while their findings have yet to be verified in larger and   
   more diverse study groups, the beneficial impact of physical activity shown in   
   the research could become an effective combination or compliment with   
   anti-dementia medication.
