If you have dementia and have a big intake of sugar at one sitting can it lead to aggressive behaviour? I have a family member who brings a whole packet of biscuits and large bag of lollies to his nursing home that he can devour in one sitting. Later he seems to become quite aggressive? Or is this just normal behaviour for dementia patients?
Hi, Large intake of sugar has been linked to aggressive behavior in both child Chat Doctor.  There have been many studies to confirm this, but results are inconclusive. In my view, since you have clearly noticed a temporal relationship between sugar intake and aggressive behavior, it will make sense to restrict his sugar intake and see what difference it makes. Please ask your family member to reduce the quantity of sweets he brings and if possible, replace them with nuts,
