To evaluate long-term efficacy and tolerability of the serotonin 5-HT1A receptor agonist, gepirone extended release (ER), a multicenter, randomized, placebo-controlled relapse prevention study was performed in patients with recurrent major depression (DSM-IV criteria). Patients 18 to 70 years, with a primary diagnosis of recurrent major depression (DSM-IV; 296.3) and a screening and baseline HAMD-17 total score >/=20 were eligible. After a 3- to 14-day (dependent on pretrial medication) single-blind placebo washout period, eligible patients entered an 8- or 12-week (depending on time to remission) open-label gepirone ER treatment period. They initially received a dose of 20 mg/d gepirone ER and were titrated to a dose of 40 to 80 mg/d. Patients who achieved remission (HAMD-17 total score </=8) were randomized to double-blind continuation of their gepirone ER treatment or placebo for 40 to 44 weeks. The primary end point was a comparison of the relapse rates between gepirone ER and placebo. Relapse was defined as a HAMD-17 total score >/=16 or discontinuation for lack of efficacy. A total of 420 patients were treated in the open-label phase. Of these, 303 (72.1%) completed the open-label phase and 250 (59.5%) fulfilled the criteria for remission and were randomized into the double-blind continuation phase (gepirone ER: n = 126; placebo: n = 124). The mean (+/-SD) final titrated dose of gepirone ER was 61.9 (+/-17.0) mg/d in the double-blind continuation phase. The relapse rate in the gepirone ER group was statistically significantly lower than that in the placebo group, 23.0% versus 34.7%, respectively (P = 0.024). During the open-label phase, adverse events that occurred in more than 5% of patients were nausea (15.7%), dizziness (13.1%), headache (12.9%), insomnia (6.2%), and vertigo (6.0%). During the continuation phase, the incidence of newly or re-emerging adverse events was similar with gepirone ER (43.7%) and placebo (42.7%). Adverse events different from those occurring during the open-label phase were not apparent. All adverse events occurred in less than 5% of patients with the exception of flu syndrome and headache. In conclusion, gepirone ER at a dose range of 40 to 80 mg/d is effective for relapse prevention in patients with recurrent major depression. It is well tolerated during long-term treatment for up to approximately one year.

Investigations of migraine comorbidity have confirmed its association with diverse psychiatric conditions. This association appears to be strongest for major depression and anxiety disorders (particularly panic and phobia), but increased comorbidity has also been reported with substance abuse and certain mood disorders. This literature also indicates that greater psychiatric comorbidity exists for migraine sufferers with aura than without. Some support is found for the notion that psychiatric comorbidity is higher in transformed migraine than in simple migraine (particularly in the case of chronic substance abuse). However, research into the possible mechanisms underlying these associations remains limited. Studies examining the order of onset and the cross-transmission of migraine and psychiatric disorders in families have been unable to distinguish fully between causal and common aetiological models of association. The conclusions are discussed in light of both methodological and conceptual issues relevant to understanding migraine comorbidity.

Migraine is a common chronic disorder that presents with recurrent attacks of headache and associated symptoms. Various somatic and psychiatric conditions have been reported as comorbid conditions with migraine. Among the psychiatric disorders that have been reported as comorbid with migraine are major depression, anxiety, panic disorder, and bipolar disorder. Recent studies discussing the comorbidity of headache and psychiatric disorders are reviewed here.

This study compared the stabilized duloxetine dose through approximately 12 weeks of treatment in patients initiating duloxetine therapy with that in patients switching to duloxetine from selective serotonin reuptake inhibitors or venlafaxine. All patients met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria for major depressive disorder. Patients (n = 112) exhibiting suboptimal response or poor tolerability to their current antidepressant medication (citalopram, escitalopram, fluvoxamine, paroxetine, sertraline, or venlafaxine) were switched to duloxetine 60 mg once daily (QD) without intermediate tapering or titration ("switching" group). A comparator group (n = 137), comprising patients not currently receiving antidepressant medication, was randomized to receive duloxetine 30 or 60 mg QD ("initiating" group). At the end of week 1, patients receiving 30 mg QD had their dose increased to 60 mg QD. During the remainder of the study, each patient's duloxetine dose could be titrated on the basis of degree of response within a range from 60 to 120 mg QD, with 90 mg QD as an intermediate dose. At the study end point, approximately one third of the patients in each treatment group were stabilized at each of the 3 studied duloxetine doses (60, 90, and 120 mg QD), and the distribution of stabilized doses among patients initiating duloxetine therapy did not differ significantly from that observed in patients switching to duloxetine. The efficacy of duloxetine in patients switching from selective serotonin reuptake inhibitor/venlafaxine did not differ significantly from that observed in untreated patients initiating duloxetine therapy (baseline-to-end point mean changes: 17-Item Hamilton Rating Scale for Depression total score, -13.1 vs. -13.5; Hamilton Rating Scale for Anxiety, -10.6 vs. -10.3; and Clinical Global Impression of Severity, -2.22 vs. -2.38, respectively). The rate of discontinuation caused by adverse events among patients switched to duloxetine was significantly lower than that in patients initiating duloxetine therapy (6.3% vs. 16.1%, P = 0.018). Treatment-emergent adverse events occurring in more than 10% of patients in both treatment groups were nausea, headache, dry mouth, insomnia, diarrhea, and constipation. In the first week of therapy, patients switched to duloxetine reported significantly lower rates of headache and fatigue compared with patients initiating duloxetine. Thus, the efficacy of duloxetine in switched patients was comparable to that observed in patients initiating duloxetine therapy. Immediate switching from a selective serotonin reuptake inhibitor or venlafaxine to duloxetine (60 mg QD) was well tolerated.

This study investigated the impact of migraine on health-related quality of life (HRQoL) among patients with major depressive disorder (MDD). We prospectively enrolled 151 consecutive psychiatric out-patients meeting DSM-IV criteria for MDD. Migraine and other headache types were diagnosed based on the International Classification of Headache Disorders, 2nd edition (2004). The Short Form-36 (SF-36) was administered as a generic instrument of HRQoL. Among 151 patients with MDD, migraine (N = 73, 48.3%) was very common. Comorbidity of migraine predicted a significantly negative impact on all physical subscales and vitality but not on the other mental subscales of the SF-36 after controlling for depression, age and gender. The presence of migraine should be considered as an important physical symptom in clinic-based MDD samples. Simultaneous management of depression and severe headaches, especially migraine, might improve HRQoL in patients with MDD.

Our objective was to assess the effectiveness and safety of the combination of duloxetine and bupropion for treatment-resistant major depressive disorder (TRD). A retrospective chart review was conducted to identify patients with major depressive disorder (MDD) who had not experienced full remission of symptoms following an adequate trial of either duloxetine (n = 3) or bupropion (n = 7), and who then received the combination of these two antidepressants for TRD. Ten patients [37.2 +/- 11.3 years of age, five women, baseline Clinical Global Impressions (CGI) scale score 4.4 +/- 1.1], seven of whom had not remitted following treatment with bupropion (330 +/- 67 mg, 20.5 +/- 12.2 weeks), and three of whom had not remitted following treatment with duloxetine (90 +/- 30 mg, 18 +/- 2 weeks) received at least 4 weeks of combination treatment. The CGI was administered when the combination was first prescribed, and following 8.8 +/- 4.0 (range, 4-16) weeks of treatment. There was a significant decrease in CGI-S (Severity) scores (4.4 +/- 1.1 to 2.1+/-0.9, P <.0001) following combination treatment. Three (30%) patients were remitters at follow-up, and six (60%) were responders who did not achieve full symptom remission. The mean maximum adjunctive duloxetine and bupropion doses were 60.0 +/- 17.3 mg and 175.0 +/- 114.5 mg, respectively. Side effects reported during combination treatment were nausea (n = 2), dry mouth (n = 2), jitteriness/agitation (n = 2), fatigue/drowsiness (n = 2), increased blood pressure (n = 1), increased sweating (n = 1), insomnia (n = 1), pruritus (n = 1), headache (n = 1), sexual dysfunction (n = 1), and weight gain (n = 1). Although preliminary, these results suggest a possible role for the combination of duloxetine and bupropion for TRD.

Major depression is a mood disorder characterized by a sense of inadequacy, despondency, decreased activity, pessimism, anhedonia and sadness where these symptoms severely disrupt and adversely affect the person's life, sometimes to such an extent that suicide is attempted or results. Antidepressant drugs are not always effective and some have been accused of causing an increased number of suicides particularly in young people. Magnesium deficiency is well known to produce neuropathologies. Only 16% of the magnesium found in whole wheat remains in refined flour, and magnesium has been removed from most drinking water supplies, setting a stage for human magnesium deficiency. Magnesium ions regulate calcium ion flow in neuronal calcium channels, helping to regulate neuronal nitric oxide production. In magnesium deficiency, neuronal requirements for magnesium may not be met, causing neuronal damage which could manifest as depression. Magnesium treatment is hypothesized to be effective in treating major depression resulting from intraneuronal magnesium deficits. These magnesium ion neuronal deficits may be induced by stress hormones, excessive dietary calcium as well as dietary deficiencies of magnesium. Case histories are presented showing rapid recovery (less than 7 days) from major depression using 125-300 mg of magnesium (as glycinate and taurinate) with each meal and at bedtime. Magnesium was found usually effective for treatment of depression in general use. Related and accompanying mental illnesses in these case histories including traumatic brain injury, headache, suicidal ideation, anxiety, irritability, insomnia, postpartum depression, cocaine, alcohol and tobacco abuse, hypersensitivity to calcium, short-term memory loss and IQ loss were also benefited. Dietary deficiencies of magnesium, coupled with excess calcium and stress may cause many cases of other related symptoms including agitation, anxiety, irritability, confusion, asthenia, sleeplessness, headache, delirium, hallucinations and hyperexcitability, with each of these having been previously documented. The possibility that magnesium deficiency is the cause of most major depression and related mental health problems including IQ loss and addiction is enormously important to public health and is recommended for immediate further study. Fortifying refined grain and drinking water with biologically available magnesium to pre-twentieth century levels is recommended.

General population studies suggest a non-casual association (comorbidity) between migraine, major depression and anxiety disorders (panic attack disorder, obsessive-compulsive disorder, generalised anxiety disorder). The risk of developing affective and anxiety disorders is not increased uniformly in the different migraine subtypes, but it is more elevated in migraine with aura patients. The relationship between migraine and depression is "bi-directional" (i. e., migraineurs have a more than three-fold risk of developing depression compared with non-migraine patients, while depression patients that have never suffered from migraine before have a more than three-fold risk of developing migraine compared with nondepressed patients) and specific (i. e., the presence of migraine or severe non-migraine headache increases a patient's risk of developing depression or panic attack disorder, whereas the presence of depression or panic attack disorder is associated with a greater risk of developing migraine, but not severe non-migraine headache). Comorbidity with psychiatric disorders has also been described for chronic tension-type headache and for chronic daily headache, although these findings are based only on clinical population data.

In a European, multicenter, double-blind study, 244 adolescents, 13 to 18 years old, with major depression were randomized to treatment with citalopram (n = 124) or placebo (n = 120). One third of the patients in both groups withdrew from the study. No significant differences in improvement of scores from baseline to week 12 between citalopram and placebo were found. The response rate was 59% to 61% in both groups according to the Schedule for Affective Disorders and Schizophrenia for school-aged children-Present episode version (Kiddie-SADS-P) (depression and anhedonia scores < or =2) and Montgomery Asberg Depression Rating Scale (MADRS) (> or =50% reduction). Remission (MADRS score < or =12) was achieved by 51% of patients with citalopram and 53% with placebo. A post hoc analysis revealed that more than two thirds of all patients received psychotherapy during this study. For those patients not receiving psychotherapy, there was a higher percentage of Kiddie-SADS-P responders with citalopram (41%) versus placebo (25%) and a significantly higher percentage of MADRS responders and remitters with citalopram (52% and 45%, respectively) versus placebo (22% and 19%, respectively). Mild to moderate treatment-emergent adverse events were reported in 75% citalopram and 71% of placebo patients, most commonly headache, nausea, and insomnia. Serious adverse events occurred in 14% to 15% in both groups. Suicide attempts, including suicidal thoughts and tendencies, were reported by 5 patients in the placebo group and by 14 patients in the citalopram group (not significant) with no pattern with respect to duration of treatment, time of onset, or dosage. In contrast, the suicidal ideation (Kiddie-SADS-P) single item showed worsening more frequently in the placebo (18%) than in the citalopram group (8%).

Duloxetine has demonstrated efficacy for the treatment of major depressive disorder (MDD) at a dose of 60 mg/day (given once daily). Whereas the target dose for the majority of patients is 60 mg/day, higher duloxetine doses (up to 120 mg/day) have been studied using a twice-daily dosing schedule. To further investigate the pharmacological profile of duloxetine within a once-daily dosing regimen at doses above 60 mg, we examined the safety and tolerability of duloxetine during a dose escalation from 60 mg/day to 120 mg/day. This single-arm, non-placebo-controlled study incorporated a 7-week dose escalation phase, in which patients and investigators were blinded as to timing of dose increases, followed by an open-label extension phase of up to 2 years duration. Patients (age >or=18 years) meeting DSM-IV criteria for MDD (n=128) received placebo for 1 week, followed by duloxetine (60 mg/day) titrated after 1 week to 90 mg/day, and after a further week to 120 mg/day. The dose of 120 mg/day was then maintained for 4 weeks. The extension phase comprised an initial 6-week dose stabilization period, during which duloxetine was tapered to the lowest effective dose, followed by continuation therapy at the stabilized dose. We assessed safety using spontaneously reported treatment-emergent adverse events (TEAEs), changes in vital signs, electrocardiograms (ECGs), laboratory analytes, and visual analogue scales (VAS) for gastrointestinal (GI) disturbance. Efficacy measures included the 17-item Hamilton Rating Scale for Depression (HAM-D-17) total score, the Clinical Global Impression of Severity (CGI-S) and Patient Global Impression of Improvement (PGI-I) scales, and VAS assessments of pain severity and interference. The rate of discontinuation due to adverse events during the acute phase of the study was 15.6%. The most frequently reported TEAEs were nausea, headache, dry mouth, dizziness, and decreased appetite. The majority of TEAEs were associated with initial duloxetine dosing; further escalations in dose produced few additional adverse events. VAS measures of GI disturbance worsened significantly compared with baseline values after 1 week of duloxetine treatment. Subsequent assessments of GI disturbance, following dose escalation to 90 mg/day and 120 mg/day, showed either no significant difference or a significant improvement from baseline. Significant improvements (P<.001) were observed in all assessed depression efficacy measures, and in five of six VAS pain outcomes, during acute phase treatment. During 2 years of extension phase therapy, the rate of discontinuation due to adverse events was 11.9%, and the only TEAEs reported by >10% of patients were upper respiratory tract infection (13.1%), headache (10.7%), and insomnia (10.7%). Mean changes from baseline to the end of the extension phase in supine systolic and diastolic blood pressure were 3.8 and 0.5 mm Hg, respectively, and there were no reports of sustained hypertension. Mean increase in heart rate was 5.9 bpm, while patients exhibited a mean weight increase of 3.1 kg over 2 years of treatment. Results from this study suggest that rapid dose escalation of duloxetine (60 mg/day --> 90 mg/day --> 120 mg/day) is safe and tolerable. Despite weekly escalation, the majority of adverse events were mild and transient and occurred in the first week of duloxetine dosing (at 60 mg once daily). Long-term treatment at a stabilized duloxetine dose was associated with a relatively low incidence of TEAEs and treatment discontinuation due to adverse events. Time course profiles of body weight and heart rate showed modest increases during 2 years of treatment [ClinicalTrials.gov number, NC T000 42575].
