Mysterious nodding disease afflicts young Ugandans

Uganda this week hosts a four-day international conference on nodding syndrome that health officials believe will lead to a clearer understanding of the mysterious disease. The disease is calling nodding syndrome, or nodding head disease, because those who have it nod their heads and sometimes go into epileptic-like fits. The disease stunts children and destroys their cognition, rendering them unable to perform small tasks. (AP Photo/Stephen Wandera)
