INTRODUCTION:

Functional disorders have been recognized over time in a segmental way, and therefore, incompletely, from diagnosis to treatment. Examples of such disorders are: migraine, irritable bowel syndrome, biliary dyskinesia, fibromyalgia, chronic fatigue syndrome, irritable bladder, mitral valve prolapse syndrome, orthostatic intolerance, orthostatic postural tachycardia, vasovagal syncope or, in conclusion, the so-called dysautonomia.

PROPOSALS:

Functional disorders, such as the syndrome called dysautonomia, could have its origin in the rapid and inappropriate responses that the amygdala makes before certain stimuli in relation to emotional memory. It is proposed to name such disorders as “dysfunctional response syndrome (REDIS)”, in order to avoid diagnostic errors in cases of secondary dysautonomia. In addition, it is proposed to establish a clinical diagnosis of these conditions and to select only those for the tilt test in case of poor response to the initial treatment, where the serotonin reuptake inhibitors seem to perform an adequate control of the symptoms.
