Hydro-alcoholic extract of Crocus sativus L. versus fluoxetine in the treatment of mild to moderate depression: a double-blind, randomized pilot trial.

Depressive disorders are very common in clinical practice, with approximately 11.3 of all adults afflicted during any a year. Saffron is the world's most expensive spice and apart from its traditional value as a food additive, recent studies indicate several therapeutic effects for saffron. It is used for depression in Persian traditional medicine. Our objective was to compare the efficacy of hydro-alcoholic extract of Crocus sativus (stigma) with fluoxetine in the treatment of mild to moderate depression in a 6-week double-blind, randomized trial. Forty adult outpatients who met the Diagnostic and Statistical Manual of Mental Disorders, fourth edition for major depression based on the structured clinical interview for DSM-IV and with mild to moderate depression participated in the trial. In this double-blind, single-center trial and randomized trial, patients were randomly assigned to receive capsules of saffron 30 mg/day (BD) (Group 1) and capsule of fluoxetine 20 mg/day (BD) (Group 2) for a 6-week study. Saffron at this dose was found to be effective similar to fluoxetine in the treatment of mild to moderate depression (F = 0.13, d.f. = 1, P = 0.71). There were no significant differences in the two groups in terms of observed side effects. The results of this study indicate the efficacy of Crocus sativus in the treatment of mild to moderate depression. A large-scale trial is justified.

Artificial neural networks in prediction of bone density among post-menopausal women.

Artificial neural networks (ANN) are promising tools in learning complex interplay of factors on a particular outcome. We performed this study to compare the predictive power of ANN and conventional methods in prediction of bone mineral density (BMD) in Iranian post-menopausal women. A database of 10 input variables from 2158 participants was randomly divided into training (1400), validation (150) and test (608) groups. Multivariate linear regression and ANN models were developed and validated on the training, and validation sets and outcomes (femoral neck and lumbar T-scores) were predicted and compared on the test group using different numbers of input variables. Results were evaluated by comparing the mean square of differences between predicted and reference values (non-central chi-square test) and by measuring area under the receiver operating characteristic curve (AUROC) around cut-off value of -2.5 for T-scores. For models with less than 3 input variables in femoral neck and 4 variables in spinal column, performance of regression and ANN models was almost the same. As more variables imported into models, ANN outperformed linear regression models. AUROC varied in 2 to 10 variable models as follows: for ANN in spine, from 0.709 to 0.774; linear models in spine, from 0.709 to 0.744; ANN in femoral neck, from 0.801 to 0.867; linear models in femoral neck, from 0.799 to 0.834. The ANN model performed better than five established patient selection tools in the test group. Superior performance of neural networks than linear models demonstrate their advantage especially in mass screening applications, when even a slight enhancement in performance results in significant decrease in number of misclassifications.

Comparison of mirtazapine and fluoxetine in the treatment of major depressive disorder: a double-blind, randomized trial.

BACKGROUND: Depression is an international public health problem. The aim of this study was to compare the efficacy and tolerability of mirtazapine and fluoxetine treatment in a sample population consisting of Iranian patients suffering major depressive disorder. METHODS: Thirty-six inpatients and outpatients with a diagnosis of major depressive disorder (Diagnostic and Statistical Manual of Mental Disorders-IV) and a score > or = 18 on the 17-item Hamilton Rating Scale for Depression (HAM-D-17) were randomly assigned to 6 weeks of treatment with mirtazapine (30 mg/day) or fluoxetine (20 mg/day). Efficacy was assessed by HAM-D-17. Information about adverse events was obtained by questioning of participants and/or their examination. Assessments were performed at weeks 0, 1, 2, 3, 4 and 6. RESULTS: Sixteen of mirtazapine-treated patients and fifteen of fluoxetine-treated patients completed the 6-week study period. Both treatment groups were well matched at baseline with respect to demographic and disease characteristics. Both drugs showed a significant improvement over the 6 weeks of treatment (P < 0.001). There was no statistically significant difference between the mean +/- SEM HAM-D scores of two groups at weeks 1, 2, 3, 4, and at the end point. There were no significant differences between two groups in terms of response to treatment (> or = 50% decrease from baseline in HAM-D-17 total score) and remission (HAM-D-17 score of < or = 7). None of the differences in reported adverse events was statistically significant. CONCLUSION: In this study, mirtazapine and fluoxetine were equally effective and well tolerated after 6 weeks of treatment in patients with major depressive disorder.

Efficacy of theophylline compared to methylphenidate for the treatment of attention-deficit hyperactivity disorder in children and adolescents: a pilot double-blind randomized trial.

Attention-deficit hyperactivity disorder (ADHD) is a common disorder of childhood that affects 3-6% of school children. Conventional stimulant medications are recognized as useful symptomatic treatments by both specialists and parents. Nevertheless, approximately 30% of ADHD children treated with them do not respond adequately or cannot tolerate the associated adverse effects. Such difficulties highlight the need for alternative, safe and effective medications in the treatment of this disorder. Theophylline is a psychomotor stimulant most widely used as a broncodilator. Purinergic modulation may be therapeutically beneficial in the treatment of psychiatric disorders. We hypothesized that theophylline would be beneficial for the treatment of ADHD and report results of a trial of theophylline compared with methylphenidate for the treatment of ADHD. A total of 32 children with ADHD as defined by DSM IV were randomized to theophylline and methylphenidate dosed on an age and weight-adjusted basis at 4 mg/kg/day (under 12 years) and 3 mg/kg/day theophylline (over 12 years) (group 1) and 1 mg/kg/day methylphenidate (group 2) for a 6-week double-blind and randomized clinical trial. The principal measure of the outcome was the Teacher and Parent ADHD Rating Scale. Patients were assessed by a child psychiatrist, at baseline and at 14, 28 and 42 days after start of the medication. No significant differences were observed between theophylline and methylphenidate on the Parent and Teacher Rating Scale scores over the trial (t = 0.49, d.f. = 24 P = 0.62 and t = 0.19, d.f. = 24 P = 0.54 respectively). Although the number of dropouts in the methylphenidate group was higher than the theophylline group, there was no significant difference between the two protocols in terms of the dropouts. In addition, headaches were observed more often in the methylphenidate group. The results suggest that theophylline may be a useful for the treatment of ADHD. In addition, a tolerable side-effect profile is one of the advantages of theophylline in the treatment of ADHD. Nevertheless, our study is small and our results would need to be confirmed in a larger study.

Cyproheptadine in the treatment of autistic disorder: a double-blind placebo-controlled trial.

OBJECTIVE: Autism is a childhood-onset disorder of unknown, possibly of multiple aetiologies. The core symptoms of autism are abnormalities in social interaction, communication and behaviour. The involvement of neurotransmitters such as 5-HT has been suggested in neuropsychiatric disorders and particularly in autistic disorder. Increased platelet 5-HT levels were found in 40% of the autistic population, suggesting that hyperserotonaemia may be a pathologic factor in infantile autism. Therefore, it is of interest to assess the efficacy of cyproheptadine, a 5-HT2 antagonist in the treatment of autistic disorder. In this 8-week double-blind, placebo-controlled trial, we assessed the effects of cyproheptadine plus haloperidol in the treatment of autistic disorder. METHODS: Children between the ages 3 and 11 years (inclusive) with a DSM IV clinical diagnosis of autism and who were outpatients from a specialty clinic for children at Roozbeh Psychiatric Teaching Hospital were recruited. The children presented with a chief complaint of severely disruptive symptoms related to autistic disorder. Patients were randomly allocated to cyproheptadine + haloperidol (Group A) or haloperidol + placebo (Group B) for an 8-week, double-blind, placebo-controlled study. The dose of haloperidol and cyproheptadine was titrated up to 0.05 and 0.2 mg/kg/day respectively. Patients were assessed by a third-year resident of psychiatry at baseline and after 2, 4, 6 and 8 weeks of starting medication. The primary measure of the outcome was the Aberrant Behaviour Checklist-Community (ABC-C) and the secondary measure of the outcome was the Childhood Autism Rating Scale (relating to people and verbal communication). Side effects and extrapyramidal symptoms were systematically recorded throughout the study and were assessed using a checklist and the Extrapyramidal Symptoms Rating Scale, administered by a resident of psychiatry during weeks 1, 2, 4, 6 and 8. RESULTS: The ABC-C and the Childhood Autism Rating Scale scores improved with cyproheptadine. The behaviour of the two treatments was not homogeneous across time (groups-by-time interaction, Greenhouse-Geisser correction; F = 7.30, d.f. = 1.68, P = 0.002; F = 8.21, d.f. = 1.19, P = 0.004 respectively). The difference between the two treatments was significant as indicated by the effect of group, and the between-subjects factor (F = 4.17, d.f. = 1, P = 0.048; F = 4.29, d.f. = 1, P = 0.045 respectively). No significant difference was observed between the two groups in terms of extrapyramidal symptoms (P = 0.23). The difference between the two groups in the frequency of side effects was not significant. CONCLUSION: The results suggest that the combination of cyproheptadine with a conventional antipsychotic may be superior to conventional antipsychotic alone for children with autistic disorder. However the results need confirmation by a larger randomized controlled trial.

Double-blind comparison of fluoxetine and nortriptyline in the treatment of moderate to severe major depression.

BACKGROUND: Depression is an international public health problem. Impairment in social and occupational functioning, increased comorbidity with other psychiatric and medical conditions, and an increased risk of mortality are a few of its consequences. Some psychiatrists have the impression that selective serotonin re-uptake inhibitors may not work as well as tricyclic anti-depressants in severe depression and/or melancholia. On the contrary, there is a general belief that selective serotonin re-uptake inhibitors are superior to the tricyclic anti-depressants in having fewer side-effects, particularly cardiovascular effects. The objective of this double-blind study was to compare the efficacy and safety of fluoxetine and nortriptyline in patients with moderate to severe major depression. METHODS: A total of 48 adult outpatients who met the Diagnostic and Statistical Manual of Mental Disorders (DSM IV), forth edition for major depression, based on the structured clinical interview for DSM IV participated in the trial. Patients had a baseline Hamilton Rating Scale for Depression score of at least 20. In this double-blind, single-center trial, patients were randomly assigned to receive nortriptyline 150 mg/day (group 1) or fluoxetine 60 mg/day (group 2) for 6-weeks. The outcome of the two groups was assessed using Hamilton Depression Rating Scale, a side-effect checklist and a regular ECG assessment. RESULTS: The results suggest that the efficacy of nortriptyline is superior to fluoxetine in this group of major depressed patients. No significant differences were observed between dropout rates in the two groups but anti-cholinergic side-effects were significantly more frequent with nortriptyline than with fluoxetine but there was no significant difference in cardiovascular effects in particular QTc prolongation. CONCLUSION: The results of the current study suggest that nortriptyline was more effective than fluoxetine in the treatment of moderate to severe depression. A larger study is warranted.

Salvia officinalis extract in the treatment of patients with mild to moderate Alzheimer's disease: a double blind, randomized and placebo-controlled trial.

BACKGROUND: Alzheimer's disease is characterized by a slow, progressive decline in cognitive function and behaviour. Acetylcholine esterase inhibitors are the only agents approved by the Food and Drug Administration for the treatment of Alzheimer's disease. All other agents prescribed for the treatment of Alzheimer's disease are used on an off-label basis. Current research into new drugs is focused on agents that will prevent, slow down and/or halt the progress of the disease process. Salvia officinalis has been used in herbal medicine for many centuries. It has been suggested, on the basis of traditional medicine, its in vitro cholinergic binding properties and modulation of mood and cognitive performance in humans, that Salvia officinalis might potentially provide a novel natural treatment for Alzheimer's disease. The objective of this study was to assess the efficacy and safety of Salvia officinalis extract using a fixed dose (60 drops/day), in patients with mild to moderate Alzheimer's disease, over a 4-month period. METHODS: This was a 4-month, parallel group, placebo-controlled trial undertaken in three centres in Tehran, Iran. Patients with mild to moderate Alzheimer's disease aged between 65 and 80 years (n = 42, 18 women) with a score of > or = 12 on the cognitive subscale of Alzheimer's Disease Assessment Scale (ADAS-cog) and < or = 2 on the Clinical Dementia Rating (CDR) were randomized to placebo or fixed dose of S. officinalis extract. Over the 16 weeks, the main efficacy measures were the change in the ADAS-cog and CDR-Sum of Boxes scores compared with baseline. In addition, side-effects were systematically recorded throughout the study using a checklist. RESULTS: At 4 months, S. officinalis extract produced a significant better outcome on cognitive functions than placebo (ADAS-cog: F = 4.77, d.f. = 1, P = 0.03) (CDR-SB: F = 10.84, d.f. = 1, P < 0.003). There were no significant differences in the two groups in terms of observed side-effects except agitation that appears to be more frequent in the placebo group (P = 0.09). CONCLUSIONS: The results of this study indicate the efficacy of S. officinalis extract in the management of mild to moderate Alzheimer's disease. Moreover, S. officinalis may well reduce agitation of patients but this needs to be confirmed.

Melissa officinalis extract in the treatment of patients with mild to moderate Alzheimer's disease: a double blind, randomised, placebo controlled trial.

OBJECTIVE: To assess the efficacy and safety of Melissa officinalis extract using a fixed dose (60 drops/day) in patients with mild to moderate Alzheimer's disease. DESIGN: A four month, parallel group, placebo controlled trial undertaken in three centres in Tehran, Iran. METHODS: Patients with mild to moderate Alzheimer's disease aged between 65 and 80 years (n = 42; 18 women, 24 men) with a score of >or= 12 on the cognitive subscale of Alzheimer's disease assessment scale (ADAS-cog) and <or= 2 on the clinical dementia rating (CDR) were randomised to placebo or fixed dose of Melissa officinalis extract. The main efficacy measures were the change in the ADAS-cog and CDR-SB scores compared with baseline. Side effects were systematically recorded. RESULTS: At four months, Melissa officinalis extract produced a significantly better outcome on cognitive function than placebo (ADAS-cog: df = 1, F = 6.93, p = 0.01; CDR: df = 1, F = 16.87, p < 0.0001). There were no significant differences in the two groups in terms of observed side effects except agitation, which was more common in the placebo group (p = 0.03). CONCLUSIONS: Melissa officinalis extract is of value in the management of mild to moderate Alzheimer's disease and has a positive effect on agitation in such patients.

Diazoxide in the treatment of schizophrenia: novel application of potassium channel openers in the treatment of schizophrenia.

OBJECTIVE: Schizophrenia is a very common disorder, affecting 1% of the world population. People who develop schizophrenia experience severe suffering and approximately 10% commit suicide. The causes of schizophrenia are still largely unknown. The relative ineffectiveness of dopamine antagonists to treat some symptoms of schizophrenia has promoted many investigators to postulate the involvement of the neuronal system in the pathophysiology of this disease. It has been suggested that the dopamine-coupled adenosine triphosphate (ATP)-sensitive channels may function by hyperpolarizing cells during metabolic stress, a function that may be disrupted in people with schizophrenia. Therefore, application of potassium channel openers/activators may be beneficial in schizophrenia. Diazoxide is a benzothiadiazine derivative related to the thiazide diuretics and a potassium channel opener. The purpose of the present investigation was to assess the efficacy of diazoxide, as an adjuvant agent in the treatment of schizophrenia. METHODS: Forty-two patients who met the DSM IV criteria for chronic schizophrenia completed the study. Patients were randomized to haloperidol 20 mg/day plus diazoxide 200 mg/day (21 subjects) or to haloperidol 20 mg/day plus placebo (21 subjects) in this 8-week double-blind study. RESULTS: Although both protocols significantly decreased the score of the positive, negative and general psychopathological symptoms over the trial period, the combination of haloperidol and diazoxide showed a significant superiority over haloperidol alone in the treatment of positive and general psychopathology symptoms as well as positive and negative syndrome scale (PANSS) total scores. In addition, in the diazoxide group a rapid onset of action on the positive symptoms was observed in week 2, whereas in the placebo group there was no significant effect at week 2. No significant differences were observed between the two protocols on the negative scores. CONCLUSION: The results of this study present a novel application for potassium channel openers/activators in the neuropsychiatric disorders and diazoxide may be an effective adjuvant agent in the management of schizophrenia.

Baclofen versus clonidine in the treatment of opiates withdrawal, side-effects aspect: a double-blind randomized controlled trial.

OBJECTIVE: Baclofen is known for the alleviation of signs and symptoms of spasticity. Reports from our previous study have suggested that it may be at least as effective as clonidine in the management of physical symptoms of opiate withdrawal syndromes and superior to clonidine in the management of mental symptoms. We now report on a randomized double-blind comparison of baclofen vs. clonidine in view of side-effects profile. METHODS: A total of 62 opiates addicts were randomly assigned to treatment with baclofen or clonidine during a 14-day, double-blind clinical trial. All patients met the DSM IV criteria for opioid dependence. Maximum daily doses were 40 mg for baclofen and 0.8 mg for clonidine. This trial medication was given three times per day in divided doses. The severity of side-effects was measured in days 0, 1, 2, 3, 4, 7 and 14. RESULTS: There was no significant difference between two treat7ments in terms of retention in treatment (dropout) and overall side-effect. Nevertheless, significantly more problems relating to hypotension were encountered with subjects on clonidine. CONCLUSION: We conclude that, the low incidence of hypotension with baclofen suggests that the drug may be suitable for outpatient ambulatory treatment of withdrawal from opiates.

Passionflower in the treatment of opiates withdrawal: a double-blind randomized controlled trial.

OBJECTIVE: Clonidine-based therapies have been utilized as the main protocol for opiate detoxification for several years. However, detoxification with clonidine has its limitations, including lack of efficacy for mental symptoms. Accumulating evidence shows the efficacy of Passiflora incarnata extract in the management of anxiety. In our continuing study of traditional medicines, which have neurotropic effects, this plant had an anxiolytic effect, which may be used as an adjuvant agent in the detoxification of opiates by clonidine. We present the results of a double-blind randomized controlled trial of clonidine plus passiflora extract vs. clonidine plus placebo in the outpatient detoxification of 65 opiates addicts. METHODS: A total of 65 opiates addicts were assigned randomly to treatment with passiflora extract plus clonidine tablet or clonidine tablet plus placebo drop during a 14-day double-blind clinical trial. All patients met the DSM IV criteria for opioid dependence. The fixed daily dose was 60 drops of passiflora extract and a maximum daily dose of 0.8 mg of clonidine administered in three divided doses. The severity of the opiate withdrawal syndrome was measured on days 0, 1, 2, 3, 4, 7 and 14 using the Short Opiate Withdrawal Scale (SOWS). CONCLUSION: Both protocols were equally effective in treating the physical symptoms of withdrawal syndromes. However, the passiflora plus clonidine group showed a significant superiority over clonidine alone in the management of mental symptoms. These results suggested that passiflora extract may be an effective adjuvant agent in the management of opiate withdrawal. However, a larger study to confirm our results is warranted.

Passionflower in the treatment of generalized anxiety: a pilot double-blind randomized controlled trial with oxazepam.

OBJECTIVE: Passionflower (Passiflora incarnata) is a folk remedy for anxiety. A double-blind randomized trial compared the efficacy of Passiflora incarnata extract with oxazepam in the treatment of generalized anxiety disorder. METHODS: The study was performed on 36 out-patients diagnosed with GAD using DSM IV criteria. Patients were allocated in a random fashion: 18 to the Passiflora extract 45 drops/day plus placebo tablet group, and 18 to oxazepam 30 mg/day plus placebo drops for a 4-week trial. RESULTS: Passiflora extract and oxazepam were effective in the treatment of generalized anxiety disorder. No significant difference was observed between the two protocols at the end of trial. Oxazepam showed a rapid onset of action. On the other hand, significantly more problems relating to impairment of job performance were encountered with subjects on oxazepam. CONCLUSION: The results suggest that Passiflora extract is an effective drug for the management of generalized anxiety disorder, and the low incidence of impairment of job performance with Passiflora extract compared to oxazepam is an advantage. A large-scale trial is justified.

Schizophrenia: etiology and pharmacotherapy.

Schizophrenia is one of the major psychiatric disorders. Psychosis, in its narrow definition, is restricted to delusions or hallucinations in the absence of insight into their pathological nature. Impairment in psychosocial function is an essential feature of schizophrenia. Research in the last decade has confirmed that schizophrenia is a brain disorder that cannot be attributed solely to psychosocial factors. It is widely accepted from twin and adoption studies that schizophrenia has a significant genetic component. In addition, it is a general belief that schizophrenia is caused by a biological abnormality, even though all attempts to identify that abnormality have been unsuccessful. A major landmark in the history of the understanding and treatment of schizophrenia was the discovery that dopamine D2-blocking agents can control the hallucinations and delusions of schizophrenic patients. However, clinicians have noticed that classical antipsychotics are generally ineffective against the negative symptoms that are prominent in patients with a chronic course. In this article, we will focus on the etiology and pharmacotherapy of schizophrenia.

The 5-HT hypothesis of schizophrenia.

Schizophrenia is a serious psychiatric illness that is responsible for a substantial proportion of mental illness worldwide. Symptoms include hallucination, delusions, thought disorder and negative symptoms, including poverty of thought and emotion, and social withdrawal. Early theories of schizophrenia implicated disturbed serotonin (5-HT) neurotransmission, but these were largely overshadowed by the dopamine theory of schizophrenia, which became established after the introduction of chlorpromazine. However, the importance of 5-HT in CNS function is once again being recognized. The ability of antipsychotic drugs to diminish positive symptoms has been correlated with their ability to block dopamine D(2) receptors, although negative symptoms are not as effectively treated by typical neuroleptics. There is increasing interest in the correlation between negative symptoms of schizophrenia and 5-HT(2) receptors. The rationale for these studies is the hypothesis that abnormal neurotransmission at 5-HT(2) receptors may be involved in the pathophysiology of schizophrenia. This review highlights recent pharmacological and clinical advances in the understanding of the potential use of serotonin 5-HT(2) receptor antagonists in the treatment of schizophrenia.

Dipyridamole in the treatment of schizophrenia: adenosine-dopamine receptor interactions.

OBJECTIVE: There is growing interest in investigating the adenosine-dopamine interaction in the ventral striatum. Adenosine plays a role opposite to dopamine in the striatum and adenosine antagonists, like caffeine, produce similar effects to increased dopaminergic neurotransmission in the striatum. In particular, a strong antagonistic interaction between adenosine A2A and dopamine D2 receptors takes place in the striopallidal GABAergic neurones. Therefore, adenosine agonists or uptake inhibitors provide a potential new treatment for schizophrenia. We undertook a pilot trial to investigate whether the combination of haloperidol with dipyridamole, an uptake inhibitor of adenosine, was more effective than haloperidol alone. METHODS: Thirty patients who met the DSM IV criteria for schizophrenia completed the study. Patients were allocated in a random fashion, 16 to haloperidol 20 mg/day plus dipyridamole 75 mg/day and 14 to haloperidol 20 mg/day plus placebo. RESULTS: Although both protocols significantly decreased the score of the positive, negative and general psychopathological symptoms over the trial period, the combination of haloperidol and dipyridamole was significantly better than haloperidol alone in decreasing positive and general psychopathology symptoms as well as PANSS total scores. CONCLUSION: Dipyridamole may be of therapeutic benefit in treating schizophrenia in combination with neuroleptics. However, a larger study to confirm our results is warranted.

Double-blind randomized controlled trial of baclofen vs. clonidine in the treatment of opiates withdrawal.

BACKGROUND: A variety of detoxification methods have been utilized for the treatment of opiate withdrawal syndrome, of which alpha-adrenergic agonists have attracted considerable attention over the last two decades. However, accumulating evidence in rats shows the efficacy of the GABAB receptor agonist, baclofen, in reducing alcohol intake and self-administration of cocaine. OBJECTIVE: To examine the ability of baclofen, in the management of opiate withdrawal. METHOD: A total of 62 opiate addicts randomly assigned to treatment with baclofen or clonidine during a 14-day, double-blind clinical trial. All patients met the DSM IV criteria for opioid dependence. Maximum daily doses were 40 mg for baclofen and 0.8 mg for clonidine given three times a day in divided doses. The severity of the opiate withdrawal syndrome was measured on days 0, 1, 2, 3, 4, 7 and 14 using the Short Opiate Withdrawal Scale (SOWS). RESULTS: Baclofen and clonidine were equally effective in treating the physical symptoms of withdrawal syndromes. However, baclofen showed a significant superiority over clonidine in the management of mental symptoms. CONCLUSION: These results suggest that baclofen might be a novel therapeutic agent for opiate withdrawal syndrome. However, a larger study to confirm our results is warranted.

Is it time to have another look at lithium maintenance therapy in bipolar disorder?

1. Bipolar disorder is typically a chronic disease entailing an episodes course, whereby psychiatric status alternates between periods of normal functioning and periods of illness. Lithium is well established and approved for the treatment of bipolar disorder. However, its efficacy in practice is not as great as expected. This retrospective record study was undertaken to determine the efficacy of lithium in bipolar disorders. 2. 48 patients who met DSM-III-R diagnostic criteria for bipolar I disorder and had been admitted once before lithium therapy and twice or more after that, were included in this study. 3. No significant difference in length between episode (frequency) was observed before and after lithium maintenance therapy. In addition, the percentages of manic episode after lithium therapy were much greater than before that. 4. The results indicate that it is worth re-examining the efficacy of lithium in bipolar disorders.
