sometimes associated with avolition?
editSince avolition is associated with mental diseases such as clinical depression, schizophrenia, and bipolar disease, how does it relate to a damaged vagus nerve? Sufferers of hypervagaltonia, subject to triggering conditions, can have episodes of plummeting heart rate and blood pressure, a cold and clammy diaphoresis, marked pallor or even cyanosis, dizziness, and may actually experience syncope (passing out) for a time. The whole episode is very similar to shock and the effects may last as long as shock, debilitating the victim from an hour to many hours afterward.
On the other hand, avolition (the opposite of volition) is defined as a symptom of psychological or psychiatric distress characterized by a lack of motivation or drive. People with avolition have difficulty starting and completing tasks, and may be disinterested in the world around them to the point where they adopt alogia (diminished to absent speech). [1] (Negative Symptoms in Schizophrenia: Avolition and Occam's Razor", http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2833114/) Avolition is due to their mental state, not from the debilitating effect of a low heart rate and blood pressure. You must have meant to simply say fatigue and/or weakness.
