A recent study led by the American Institute of Medicine has discovered that traumatic brain injury suffered by soldiers in combat can trigger Alzheimer's.
Other symptoms have also been found to reflect those found in patients with Parkinson's disease and associated disorders, leading the organisation to attempt to understand the link between the disease and a possible cure.
The chairman of the committee which authored the report, George W Rutherford, explained that explosive devices which triggered the symptoms were becoming much more common due to the modern nature of war.
Mr Rutherford explained that non-penetrating brain trauma was more common due to the use of roadside bombs in Iraq and Afghanistan.
He continued: "It is important to identify and understand any long-term health effects of these injuries so that wounded service members do not lose valuable time for therapy and rehabilitation."
Sunday marked the 67th anniversary of the Pearl Harbor attack which led to the entry of the United States into the Second World War, with many wounded war veterans in attendance.
