Comorbid anxiety and depressive features are common in clinical practice, and DSM-IV has included mixed anxiety-depression in its appendix of conditions needing nosological refinement. The presence of comorbid anxiety has prognostic implications. For example, prospective studies of patients with depression have found that the co-occurrence of panic attacks was correlated with a poor outcome (Coryell et al. 1988 van Valkenburg et al. 1984). Some evidence suggests that such patients do better with MAOls. Likewise, patients with depression and obsessive-compulsive disorder may be more resistant to treatment, even with SSRls (Hollander et al. 1991)... 

Psychiatry - INH-induced common psychiatric conditions include psychosis, obsessive-compulsive disorders and mood alterations. INH-induced delirium (with all clinical features of delirium according to Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria) has been reported recently [47 ].
