The term “pushing on a string” relies on the metaphor of trying to move two objects joined by a string. One can pull on one of the objects, relying on the string to tug the other object along, but good luck getting any kind of movement by pushing instead. In fact, no movement is likely to occur until the two objects bump against one another.
The metaphor seems to aptly describe the situation many families face when PD reaches a point marked by inactivity and passivity. Many partners respond to this situation with strong pressure on the person with PD to become more actively engaged in their life again. However, the effect is nearly always that of pushing on a string.
Passivity can arise with a change in the functional integrity of the neural pathways facilitating communication between deep brain structures and areas involved in high level cognitive processing. Insult to these neurological pathways can result in a decline in self-initiated, motivated behaviors. This is one aspect of the organic state known as executive dysfunction. To date, no medications are available to treat this amotivational syndrome.
Amotivational syndrome is somewhat mysterious to a neurologically-intact (“normal”) person. It is not the case that a person with the condition is lazy or doesn’t care about doing those speech or physical therapy exercises at home. Rather, sometimes he or she simply does not think to do them. Depending on the severity of the condition, there may be difficulty breaking through the cognitive inertia necessary to get started even when a reminder brings the need to do something to mind.
Our clinical experience is that some degree of amotivational syndrome is very common in PD and that it may come surprisingly early in the disease process. Individuals challenged by PD early in life may not be spared and in some cases we have found that this presentation, as well as other forms of executive dysfunction, may appear long before motor symptoms drive a person to see a neurologist for the first time. We must qualify qualify this hypothesis by saying that our sampling is likely to be biased because so many of the people who present for therapy and neurocognitive evaluations do so precisely because they are experiencing life problems. Many of their reports about “thinking problems” are retrospective and therefore not rigorous in a scientific sense. On the other hand, we have a lot of conversations with families who are not actively seeking our services but still report elements of cognitive dysfunction that have a flavor of amotivational syndrome. The volume of reported problems has been great enough to get our attention.
Amotivational syndrome can look a lot like depression and frequently co-exists with it. It is always important to rule out or treat this psychiatric disorder because the two conditions can operate in tandem to amplify behavioral inertness. Depression is potentially treatable through a combination of pharmacology and psychotherapy. It is also important to determine if the loved one is experiencing dementia, a far more serious condition that produces a more pervasive decline in executive function.
Amotivational syndrome in a non-demented, non-depressed individual can be managed if one avoids pushing a string. Take it as gospel that demanding, arguing, begging, wheedling, or haranguing is likely to produce a minimal effect at best. Expect copious amounts of frustration and resentment from everyone.
It is important to accept that the problem is present, permanent, and now a fact of life. The situation calls for flexibility, ingenuity, and patience. When amotivational syndrome is truly the reason the loved one struggles with meeting the demands of the day, the dynamics of the relationship have changed and it may become necessary to be gently directive but not overly reactive. Doing things that are within the person’s behavioral repertoire may actually reinforce the behavioral inertia by building up a sense of helplessness.
Open communication is the key to avoid pushing a string. Negotiate a schedule for regular daily activities; mutually establish a list of household chores the person with PD can reasonably manage; make it clear that diminished motivation is not the equivalent of diminished responsibility. It is fair and perfectly reasonable to set timers, post reminders, and to cue with statements like “the trash needs to go out.” If the negotiated activities are not done, it is also reasonable to hold the person accountable by reminding them that that the lack of performance has consequences they alone must accept. Individuals with amotivational syndrome struggle with emotional and behavioral inertia but they are not incapable of doing what is in their best interest when it is clear it is their own responsibility. Amotivational syndrome encumbers but it does not prohibit.
Amotivational syndrome presents challenges to a family with Parkinson’s. It is a potential source of stress but it is also an opportunity to enrich relationships and build stronger bonds. The best response is to avoid pushing a string.
