Depression is a common psychiatric problem associated with epilepsy. Interictal depressive symptoms are more frequent and severe in epileptic patients than in subjects with comparable chronic neurologic diseases or physical handicaps. Epileptic depression was characterized as major or dysthymic:
bipolar depression
is rarely described. Several Authors are of opinion that interictal depression is more frequent in epileptics with temporal lobe foci and, in particular, with temporal left hemisphere lesions. The pathogenetic significance of depression in epileptics is unclear. Some suggest the hypothesis that depression represents behavioral effects of neurochemical responses to brain injury for
asymmetrical
hemispheric distribution of neural substrate for mood. We think that depression in epileptic patients does not represent a psychological reaction to a particular cognitive or physical impairment, but it is in some way related to the type of epilepsy. In addition, some antiepileptic drugs may have psychotropic effects: the most positive findings were associated with carbamazepine.

Bipolar patients with a rapid cycling clinical course constitute an interesting sub-group for studies focused on the pathophysiology of the disorder, since several switches can be studied by the investigators in a short period of time. At present, functional neuroimaging techniques, as SPECT and PET, may be used for the neurobiological study of affective disorders. Few longitudinal functional neuroimaging studies assessing the different phases of bipolar disorder have been carried out. However, the published data suggest an
asymmetrical
temporal lobe dysfunction in depressive and manic phases of
bipolar depression
. Further studies with larger samples of patients are needed in order to improve our knowledge of the pathophysiology of bipolar disorder.
