Abulia, or aboulia for nonphysiological occurances, is generally referred to as the absence of the ability and/or will to make decisions independently. This is not to be confused with simple indecisiveness, as abulia is physiological. Aboulia, however, can be synonomous with extreme indecisiveness. 

The decision making process involves several area of the cerebral cortex, and damage to these areas can reduce their function, but the extent of the damage typically is extreme in most cases.
