Abulia

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 synonymous 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.
