The Swiss physician Adolf Lukas Vischer described a psychiatric syndrome among prisoners of war, the 'barbed-wire disease' that follows a long-term incarceration and which involved boredom, confusion, clouding of consciousness and amnesia. Vischer first identified this as an important clinical issue. Later in life, he became one of the first geriatricians and gerontologists.
