[Multidisciplinary Approach to Depression. Preliminary Results].

In the present study, clinical interview, Visual Evoked Potentials, psychological tests, TRH test, plasmatic MHPG dosage were investigated in 30 depressed patients with major depressive disorders. All the explorations were realised before and after 28 days of an antidepressant treatment. Thanks to analysis we found out the value of psychological tests. The study of evoked potentials brings to light the existence of electrophysiological variables, subordinate to the clinical state. On the contrary, "TRH Test" does not give us any useful indication, and plasmatic MOPEG dosage, although it confirms the existence of two groups of depressed patients, does not suggest any relationship with evolutive types.
