   Frontotemporal dementia linked to high BMI, carb consumption

   NEW YORK (Reuters Health) - Patients with two subtypes of frontotemporal   
   dementia consume more sugar and other carbohydrates than normal and they have   
   a higher-than-average BMI and waist circumference, a new study has found.   
   Patients with the behavioral variant of the disease and another subtype,   
   semantic dementia, have been known to change their eating habits, and this new   
   research measures some of those changes.   
      
   "Our findings would suggest that it is important to address these eating   
   changes and try to regulate food intake, given their widespread impact on   
   health," senior author Dr. Olivier Piguet, a neuropsychiatrist at the   
   University of New South Wales in    
   Sydney, Australia, told Reuters Health by email.   
      
   "These changes are associated with changes in other measures of health, such   
   as increased cholesterol, triglycerides, insulin resistance, as well as   
   increased body mass index. So, it looks like eating changes may have an impact   
   on future health in these    
   patients, and may impact on disease progression," said Dr. Pigquet.   
      
   The findings were published online October 20 in JAMA Neurology.   
   The researchers evaluated 75 patients, whose caregivers administered   
   questionnaires. Twenty-one patients had behavioral variant frontotemporal   
   dementia, 26 had semantic dementia and 28 had Alzheimer's disease.   
   Compared to the Alzheimer's patients, patients with the behavioral variant had   
   significantly higher scores in every field of eating habits measured,   
   including swallowing, appetite and eating habits.   
      
   But there were few significant differences between the other groups.   
   The researchers measured the patients' hunger by combining the numerical   
   results from questions about hunger, satiety and how much more the patient   
   said he or she could eat. When looking at any one of the day's three meals,   
   there were no significant    
   differences between any of the groups.   
      
   But after combining each day's scores into a daily average, patients with   
   behavioral variant frontotemporal dementia had significantly higher score,   
   meaning that they were hungrier on average, than either of the other dementia   
   groups, though not than a    
   control group.   
      
   The study found a trend among the two groups of patients with frontotemporal   
   dementia that suggests they eat more calories, but it was not statistically   
   significant. The significant differences were in the kinds of calories   
   consumed.   
   Patients with the behavioral variant consumed more carbohydrates than the   
   controls at 251 g/d compared to 170 g/d. And the patients with semantic   
   dementia consumed more sugar than the controls at 114 g/d compared to 76 g/d.   
      
   There were no significant differences between the groups in fat and protein   
   consumption.   
      
   Both groups of patients with frontotemporal dementia had higher BMI and waist   
   circumference compared with the controls.   
      
   Patients with the behavioral variant had an average BMI of 29.65 and waist   
   circumference of 106.2 cm. The semantic dementia patients had a BMI of 28.71   
   and waist circumference of 101.3 cm, while the controls had a BMI of 24.05 and   
   waist circumference of    
   91.2 cm.
