Functional and Dissociative Neurological Symptoms : a patient's guide


Causes / Mechanisms

Figure 1 - Contralateral hypoactivation Vuilleimie

Brain imaging is beginning to show us how the nervous system can go wrong in patients with functional and dissociative symptoms.,

This picture shows a SPECT scan of patients who had functional weakness and sensory symptoms on one side of their body. The scan shows that when they had these symptoms, there was a part of the opposite side of the brain which was not working properly (shown in yellow)

These types of scan show that the nervous system and brain function does go wrong in these illnesses. But it doesn't mean that you can't do anything about it
