![]() This would avoid the use of antidepressants that unnecessarily increase cardiac risk in MD. The DSM-5 symptoms exhibited by the patient may help the choice of adequate pharmacological treatment. As SD is associated with the non-somatic cluster, these patients are at risk of committing suicide. Among the secondary DSM-5 criteria, the somatic cluster discriminated ND from MD and the non-somatic cluster SD from MD patients.ĭiscussion: The presence of the somatic cluster in MD may indicate decreased vagal tone and/or increased sympathetic tone, leading to higher cardiovascular risk. Results: Discriminant analysis showed that Depressed Mood was the most reliable symptom to discriminate ND from MD. MD and ND subjects were randomly sampled to match the demographic variables of the SD group. ND was defined considering both the absence of DSM-5 criteria for depression and the HAMD score. ![]() In depressed subjects, MD and SD were defined considering the HAMD scores. Material and Methods: Depression was diagnosed based on the Structured Clinical Interview for DSM-5® Disorders. Objective: To verify whether the DSM-5 symptoms would be able to discriminate SD from MD and MD from non-depressed (ND) subjects. However, clinicians usually do not use scales. Previously, we reported that patients with moderate depression (MD) exhibit greater impairments in cardiac-autonomic modulation than severely depressed (SD) patients. Therefore, it is commonly assessed with scales such as the Hamilton Depression Rating Scale (HAMD). ![]() In contrast, depression severity is a continuous variable. Although the secondary symptoms can be divided into somatic and non-somatic clusters, the DSM-5 identify depression in all or none fashion. One of them must be either Depressed mood or Anhedonia, named main criteria. ![]() Background: Depression diagnosis requires five or more symptoms (Diagnostic and Statistical Manual of Mental Disorders-DSM-5). ![]()
