[Do psychomotor symptoms predict the treatment response of patients with depressive disorders?]
Background:
Patients with depressive disorders may present with typical psychomotor symptoms such as retardation and/or agitation. So far, however,the prognostic significance of these symptoms is unclear.
Aim:
To present an overview in which we assess to what extent psychomotor symptoms can predict the effect of the type of treatment that patients with depressive disorders receive.
Method:
We searched the literature using Medline.
Results:
Psychomotor symptoms might predict that the patient will respond more favourably to treatment with dopaminergic antidepressants and broad-spectrum antidepressants (TCAs) and particularly to electroconvulsive therapy than to 'single-acting serotonergic antidepressants' - but, so far, the scientific evidence for the foregoing is limited.
Conclusion:
In our view psychomotor symptoms do have a predictive value with regard to treatment response, but further research is needed.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
