http://en.wikipedia.org/wiki/Decompensating
Decompensation is the functional deterioration of a previously working structure or system. Decompensation may occur due to fatigue, stress, illness, or old age. When a system is "compensated", it is able to function despite stressors or defects.
Decompensation describes an inability to compensate for these deficiencies. It is a general term commonly used in medicine to describe a variety of situations.
For example, cardiac decompensation may refer to the failure of the heart to maintain adequate blood circulation, after long-standing (previously compensated) vascular disease (see heart failure).
In psychiatry, decompensation is the deterioration of mental health in a patient with previously maintained psychiatric illness, leading to a diminished ability to think and carry on daily activities.
