This is the type of all the "partial" Aboulias.

There may be no lack in determination and effort, yet the action may be impossible.
But, in contrast with this, there is a more grave defect called "general" Aboulia.

Here we find a weakening of resolution, of determination, associated with some lack of self-control showing itself frequently by a certain hesitation or indecision.

The patient says: "I can not make up my mind," "I can not decide." In exaggerated cases it becomes a form of mania called "insanity of doubt." The patient stands before a door for an hour hesitating as to whether he can open it or not, or carries to its extreme the experience we all sometimes have of finding it necessary to return again and again to make sure that we have locked the door or shut the draught of the furnace.
With these illustrations our notice of mental defects may terminate.
The more complex troubles, the various insanities, manias, phobias, etc., can not be briefly described.

Moreover, they are still wrapped in the profoundest obscurity.
