topiramate and Mood-Disorders

Alcohol dependence is a major health problem worldwide. Various pharmacological agents have been used in the management of alcohol dependence. This review looks at the role of topiramate and other anticonvulsants in the management of alcohol dependence. Topiramate is the most widely used anticonvulsant in the treatment of alcohol dependence. The literature on topiramate is reviewed and critically analyzed, along with its proposed mechanism of action in alcohol dependence. A review of data available on other anticonvulsants like carbamazepine, oxcarbazepine, sodium valproate, gabapentin and levetiracetam are presented and their potential in the treatment of alcohol dependence is considered, together with future research directions.

This article deals with the effect of antiepileptic drugs on mood when applied in epileptic patients. The author points that depressive symptoms occur significantly more frequently in epilepsy and there are more common factor in the mechanism of action of the antiepileptic and antidepressive agents. The relevant literature is surprisingly poor. Primary and large analysis regarding affective disorders coexisting with epilepsy is still lacking. From this aspect some antiepileptic drugs have not been investigated at all. The consequences of the papers originates from indirect sources like adverse events profiles of the study drugs or from psychometric tests performed for avoiding exclusion criteria of psychological nature. On the other hand the paper deals also with the difficulties of such kind of investigations concerning the classification of depressive signs presenting with epilepsy, special considerations of inclusion of appropriate patients and particular limits of the measuring and follow-up of the observed effect. As the result of the detailed analysis of the literature the author recommends lamotrigine, carbamazepine and oxcarbazepine as first choice antiepileptic drug for epileptic patients suffering from depressive disorder, too. On the contrary, phenobarbital, topiramate and vigabatrin are able to worsen the affective symptoms. Aimed, randomized, controlled studies are necessary for recognizing the whole spectrum of psychotropic effects of antiepileptic drugs and for their successful and individually tailored application in patients in their comorbid states. Author calls the attention for the importance of the treatment of depressive states frequently occurring in epileptic patients. These symptoms modify patient compliance and are able to influence even the epileptic process itself.

To review the evidence of weight loss with use of topiramate in patients with mood disorders.. Literature search included MEDLINE (1966-December 2003), International Pharmaceutical Abstracts (1970-December 2003), and EMBASE (1980-December 2003). Search terms included topiramate, weight loss, adverse effect, mood disorders, bipolar disorder.. Weight gain is a common adverse effect of many agents used to treat mood disorders. Topiramate has been evaluated in the management of some mood disorders, and weight loss may be a beneficial side effect in these patients. Case reports, letters to the editor, prospective investigations, and retrospective observational studies were reviewed to identify evidence of weight loss with topiramate use in patients with mood disorders.. Current evidence suggests an association between topiramate and weight loss. Based on the limited data, controlled studies need to be conducted to define the role of topiramate in patients with mood disorders who would also benefit from weight reduction.

The increasing use of anticonvulsant drugs in psychiatry has prompted greater awareness of their effects on a range of psychiatric domains, including cognition. Older versus newer antiepileptic drugs have been reported to either worsen or enhance cognitive performance in clinical populations, and the extent to which cognitive disturbances may reflect iatrogenic factors versus psychopathology is subject to debate. We review current information about the role of anticonvulsants in cognition, with particular emphasis on newer compounds (such as lamotrigine, gabapentin, and topiramate), the cognitive dimensions of affective illness, and the clinical approach to evaluating cognition in psychiatric patients taking anticonvulsant drugs over time.

Benzodiazepines are the standard pharmacotherapies for ethanol detoxification, but concerns about their abuse potential and negative effects upon the transition to alcohol abstinence drive the search for new treatments. Glutamatergic activation and glutamate receptor up-regulation contribute to ethanol dependence and withdrawal. This study compared 3 antiglutamatergic strategies for ethanol detoxification with placebo and to the benzodiazepine, diazepam: the glutamate release inhibitor, lamotrigine; the N-methyl-D-aspartate glutamate receptor antagonist, memantine; and the AMPA/kainite receptor inhibitor, topiramate.. This placebo-controlled randomized single-blinded psychopharmacology trial studied male alcohol-dependent inpatients (n=127) with clinically significant alcohol withdrawal symptoms. Subjects were assigned to 1 of 5 treatments for 7 days: placebo, diazepam 10 mg TID, lamotrigine 25 mg QID, memantine 10 mg TID, or topiramate 25 mg QID. Additional diazepam was administered when the assigned medication failed to suppress withdrawal symptoms adequately.. All active medications significantly reduced observer-rated and self-rated withdrawal severity, dysphoric mood, and supplementary diazepam administration compared with placebo. The active medications did not differ from diazepam.. This study provides the first systematic clinical evidence supporting the efficacy of a number of antiglutamatergic approaches for treating alcohol withdrawal symptoms. These data support the hypothesis that glutamatergic activation contributes to human alcohol withdrawal. Definitive studies of each of these medications are now needed to further evaluate their effectiveness in treating alcohol withdrawal.

Borderline personality disorder (BPD) is a complex mental disease associated with severe serious functional impairment, affective instability, and impulsive aggression. The aim of this study was to compare the efficacy of topiramate versus placebo in the treatment of aggression in men with borderline personality disorder.. We conducted an 8-week, double-blind, placebo-controlled study of topiramate in 42 male subjects (42 of 44) meeting DSM-IV criteria for BPD. The Structured Clinical Interview (SCID I and II) was carried out. The subjects were randomly assigned to topiramate (n = 22) or placebo (n = 20).. Significant changes on four STAXI scales (State Anger, p < .01; Trait Anger, p < .05; Anger Out, p < .01; Anger Control, p < .01) were observed in the subjects treated with topiramate. A nonsignificant difference was found on the Anger In scale (p = .86). Additional significant weight loss was observed (difference in weight loss between the both groups was 5.0 kg, p < .01, 95% confidence interval = [-6.5 to 3.4]). All subjects tolerated topiramate relatively well.. Topiramate appears to be an effective agent in the treatment of anger in men with BPD. Mild weight loss can be expected.

The weight-gain caused by many psychotropic drugs is a major cause for poor compliance with such medications and could also increase cardio-vascular morbidity among psychiatric patients. Recent reports have shown that the anticonvulsant topiramate causes weight loss in various patient groups. The drug has also shown effectiveness in open trials as a mood stabilizer in patients with affective disorders, but not in controlled trials in the acute treatment of mania. We used topiramate to treat 12 patients with affective disorders who had a body-mass index > 30 kg/m2.. Topiramate was prescribed as part of our routine clinical practice, as an add-on medication, or as a replacement of a mood stabilizer. Patients' weight was recorded in 1 to 2 monthly intervals. Patients were followed up for between 6 and 12 months. The final dose of topiramate varied from 200 to 600 mg/day.. Topiramate was effective in reducing the weight in 10 out of the 12 patients. At six months the 12 patients had lost a mean of 7.75 kg (SD = 6.9 kg, p < 0.001) and at 12 months 9 patients had lost a mean of 9.61 kg (SD = 6.7 kg, p = 0.003). Three patients stopped the treatment: one due to side effects, one due to possible side effects, and one suffered a manic relapse and showed no sustained weight loss. There were no other clear changes in the course of illness of the patients.. The evidence of a strong weight-reducing potential of topiramate is indisputable and clinically significant. Topiramate could be considered in the treatment of bipolar patients who are overweight, or whose concerns about weight gain compromise their compliance with long-term prophylactic medication. So far there is no evidence that topiramate has anti-manic effect and it should not be used as monotherapy.

Mood-modulating profiles of antiepileptic drugs (AEDs) have been classified by Ketter, Post, and Theodore [Neurology 1999; 53 (5, Suppl. 2) S53-76] into two classes: the first class is assumed to have deactivating effects related to GABA potentiation, and the second class is assumed to have activating effects that are associated with glutamate attenuation. We tested this hypothesis by reviewing the multiple mechanisms of action of topiramate (TPM) and levetiracetam (LEV) together with clinical behavioral side effects of patients who had been treated with TPM and LEV in a tertiary referral center for epilepsy. We found LEV to manifest activating and deactivating side effects equally and TPM to act as a deactivating AED, with tiredness/sleepiness side effects being predominant. TPM, in comparison to LEV, was found to be associated with a high incidence of side effects. Testing the hypothesis of Ketter et al. (1999) the deactivating effects of TPM may be coupled to a predominance of potentiation of GABA, but the oversimplified basis of the model needs to be acknowledged.

Whereas the efficacy of the newer antiepileptic drugs (AEDs) is well established, there remain questions regarding their cognitive side effects. Therefore, we performed a comparative open randomized trial with TPM and TGB as add-on therapy, with particular consideration of cognition, mood, and health-related quality of life (HRQOL).. Forty-one patients with refractory epilepsy were randomly assigned to one of the two treatment groups (TPM vs TGB) and received neuropsychological testing at baseline (T1), after titration (3 months, T2), and during the maintenance phase (another 3 months, T3). Tests included measures of intelligence, attention, working memory, episodic memory, language, and self-report questionnaires regarding mood and HRQOL. Twenty patients (8 TPM, 12 TGB) discontinued the trial for different reasons (no group difference).. Seizure outcome (intention-to-treat analysis) was comparably good in both groups (8.1% seizure free, 29.7% seizure reduction>50%). From baseline to after the titration paired sample t tests revealed significant deterioration in verbal fluency, language comprehension, working memory, and visual block tapping under TPM and a deterioration in verbal memory (delayed free recall) in the TGB group. These functions remained stable in the maintenance phase. Self-report measures initially indicated concerns about AED side effects in both groups and concerns about worse cognitive functioning and depression under TPM. In the maintenance phase the TGB group reported feeling a lack of energy, whereas patients on TPM demonstrated improvement on all QOLIE scales on a descriptive level.. This study demonstrates the comparable efficacy of TPM and TGB. Consistent with previous reports, TPM but not TGB appears to be associated with persistent negative cognitive side effects on frontal lobe-associated functions, the degree of which may be estimated by the fact that this effect was observed with a very small sample size. In contrast, in patients taking TPM, initially negatively affected HRQOL returns to baseline in the long run on a descriptive level. The latter finding may be interpreted in accordance with the observation that objective performance and subjective self-report under TPM can be dissociated.

The relative cognitive and behavioral effects of lamotrigine (LTG) and topiramate (TPM) are unclear.. The authors directly compared the cognitive and behavioral effects of LTG and TPM in 47 healthy adults using a double-blind, randomized crossover design with two 12-week treatment periods. During each treatment condition, subjects were titrated to receive either LTG or TPM at a target dose of 300 mg/day for each. Neuropsychological evaluation included 17 measures yielding 41 variables of cognitive function and subjective behavioral effects. Subjects were tested at the end of each antiepileptic drug (AED) treatment period and during two drug-free conditions (pretreatment baseline and 1 month following final AED withdrawal).. Direct comparison of the two AEDs revealed significantly better performance on 33 (80%) variables for LTG, but none for TPM. Even after adjustment for blood levels, performance was better on 19 (46%) variables for LTG, but none for TPM. Differences spanned both objective cognitive and subjective behavioral measures. Comparison of TPM to the non-drug average revealed significantly better performance for non-drug average on 36 (88%) variables, but none for TPM. Comparison of LTG to non-drug average revealed better performance on 7 (17%) variables for non-drug average and 4 (10%) variables for LTG.. Lamotrigine produces significantly fewer untoward cognitive and behavioral effects compared to topiramate (TPM) at the dosages, titrations, and timeframes employed in this study. The dosages employed may not have been equivalent in efficacy. Future studies are needed to delineate the cognitive and behavioral effects of TPM at lower dosages.

Limited population-based data are available on antiepileptic drug (AED) treatment patterns in women of childbearing age with epilepsy; the current population risk is not clear.. To examine the AED treatment patterns and identify differences in use of valproate sodium and topiramate by comorbidities among women of childbearing age with epilepsy.. A retrospective cohort study used a nationwide commercial database and supplemental Medicare as well as Medicaid insurance claims data to identify 46 767 women with epilepsy aged 15 to 44 years. The eligible study cohort was enrolled between January 1, 2009, and December 31, 2013. Data analysis was conducted from January 1, 2017, to February 22, 2018.. Cases required an International Classification of Diseases, Ninth Revision, Clinical Modification-coded epilepsy diagnosis with continuous medical and pharmacy enrollment. Incident cases required a baseline of 2 or more years without an epilepsy diagnosis or AED prescription before the index date. For both incident and prevalent cases, focal and generalized epilepsy cohorts were matched by age, payer type, and enrollment period and then compared.. Antiepileptic drug treatment pattern according to seizure type and comorbidities.. Of the 46 767 patients identified, there were 8003 incident cases (mean [SD] age, 27.3 [9.4] years) and 38 764 prevalent cases (mean [SD] age, 29.7 [9.0] years). Among 3219 women in the incident epilepsy group who received AEDs for 90 days or more, 3173 (98.6%) received monotherapy as first-line treatment; among 28 239 treated prevalent cases, 18 987 (67.2%) received monotherapy. In 3544 (44.3%) incident cases and 9480 (24.5%) prevalent cases, AED treatment was not documented during 180 days or more of follow-up after diagnosis. Valproate (incident: 35 [5.81%]; prevalent: 514 [13.1%]) and phenytoin (incident: 33 [5.48%]; prevalent: 178 [4.53%]) were more commonly used for generalized epilepsy and oxcarbazepine (incident: 53 [8.03%]; prevalent: 386 [9.89%]) was more often used for focal epilepsy. Levetiracetam (incident: focal, 267 [40.5%]; generalized, 271 [45.0%]; prevalent: focal, 794 [20.3%]; generalized, 871 [22.2%]), lamotrigine (incident: focal, 123 [18.6%]; generalized, 106 [17.6%]; prevalent: focal, 968 [24.8%]; generalized, 871 [22.2%]), and topiramate (incident: focal, 102 [15.5%]; generalized, 64 [10.6%]; prevalent: focal, 499 [12.8%]; generalized, 470 [12.0%]) were leading AEDs prescribed for both focal and generalized epilepsy. Valproate was more commonly prescribed for women with comorbid headache or migraine (incident: 53 of 1251 [4.2%]; prevalent: 839 of 8046 [10.4%]), mood disorder (incident: 63 of 860 [7.3%]; prevalent: 1110 of 6995 [15.9%]), and anxiety and dissociative disorders (incident: 57 of 881 [6.5%]; prevalent: 798 of 5912 [13.5%]). Topiramate was more likely prescribed for those with comorbid headache or migraine (incident: 335 of 1251 [26.8%]; prevalent: 2322 of 8046 [28.9%]).. Many women appear to be treated with valproate and topiramate despite known teratogenicity risks. Comorbidities may affect selecting certain AEDs despite their teratogenicity risks.

Zonisamide, a sulfonamide analog, is an antiepileptic drug with mechanisms of action similar to topiramate. Because of its pharmacodynamic and pharmacokinetics profiles, zonisamide is also potentially suitable for migraine prevention.. Tolerability and effectiveness of zonisamide for migraine prophylaxis in patients with a good response to topiramate, but interrupting it for intolerable side effects, were evaluated in 34 patients. After a 1-month period of wash-out, patients were treated with zonisamide (up to a 100 mg/day dosage) for 6 consecutive months.. Zonisamide was well tolerated, only 4 (12%) patients reported transient and tolerable side effects. Mean number of days with headache per month was reduced from 14.9 ± 5.3 during the wash-out period to 2.5 ± 0.6 after 6 months of zonisamide (P < .001). We observed a significant reduction in headache severity and disability, as assessed by visual analog scale and migraine disability assessment scale. Finally, when compared with the 1-month period prior to starting zonisamide, a reduced use of analgesics was recorded at the end of the follow-up.. Our findings support the use of zonisamide as an alternative therapy for migraine prevention in patients with good response, but poor tolerance to topiramate.

The cerebellar cognitive affective syndrome (CCAS) represents a spectrum of cerebellar-induced neurocognitive and affective disturbances. In this report a patient is described who developed CCAS under a treatment with standard daily dose of the anti-epileptic drug topiramate (TPM). Cognitive disturbances consisted of impaired visuo-spatial memory, concentration deficits and executive dysfunctions. Behavior and affect were characterized by marked mood-swings and several disinhibited symptoms. After a gradual discontinuation of treatment with topiramate, a complete remission of the cognitive and affective symptoms was observed within 6 weeks. Functional neuroimaging studies by means of SPECT were conducted 2 weeks and 8 months following TPM discontinuation. This case report seems to suggest that functional disruption of the cerebello-cerebral circuitry, leading to CCAS, can follow treatment with topiramate.

Continuation treatment for bipolar disorder often consists of a mood stabilizer and a second-generation antipsychotic. Quetiapine has been shown to be an effective treatment for acute mania and acute bipolar depression, but there are limited data for its use in continuation treatment. This study examined the effectiveness of open-label adjunctive quetiapine therapy for continuation treatment in patients with bipolar disorder. Prospectively collected life chart data from 63 outpatients with bipolar disorders, most recent episodes depressed, manic, or cycling, who received adjunctive quetiapine therapy as part of standard acute treatment were analyzed. Patients had 4 or more weeks of prequetiapine baseline data and at least 2 weeks of quetiapine treatment with no other medication changes. Patients were grouped by baseline symptoms; depression only, mania only, or both mania and depression (cycling group). Owing to small mania and well groups (n=4), differences between depression and cycling groups were examined and mania and well groups excluded. Fifty-five patients were included in the analyses. The primary outcome measure was change in mood severity from baseline to change in treatment regimen, as measured by the NIMH Life Charting Method. Patients received adjunctive quetiapine for a mean of 122 (SD=149) days. Both groups showed significant improvement in depression ratings and time spent depressed by week 10. Both groups showed significant improvement in overall mood. No between-group differences in improvement were found. Adjunctive quetiapine may be useful as continuation treatment in bipolar populations with both pure depressive and cycling symptoms. Further controlled studies are warranted.

To report the case of a patient who experienced adverse events in succession to antiepileptic medications being used for both antiepileptic and mood-stabilization benefit.. A 46-year-old white woman developed hyponatremia with carbamazepine, hyperammonemia with divalproex, cognitive impairment with topiramate, and hyponatremia with oxcarbazepine. The patient was stabilized physically and psychiatrically on levetiracetam without any noted adverse events.. The adverse events in this report have been associated with the medications in question. The patient's presentation is unique, as she developed adverse events in succession to antiepileptic drugs being used to treat both a seizure disorder and symptoms of mood instability. The Naranjo rankings for the reported adverse events indicated the associations were probable (carbamazepine, divalproex, oxcarbazepine) and possible (topiramate). After repeated incidences of intolerability to these drugs, levetiracetam was initiated and provided both seizure control and mood-stabilizing benefits, which eventually led to hospital discharge.. Levetiracetam may provide mood-stabilizing qualities through a mechanism that is unique from that of other antiepileptic agents used for their mood-stabilizing properties. There are potential advantages with levetiracetam, as no specific therapeutic drug monitoring parameters need to be followed after its introduction. Additionally, this case emphasizes the importance of therapeutic drug monitoring and frequent assessments to prevent physical and psychiatric adverse reactions.

The aim of this study was to analyze in detail psychopathology associated with topiramate (TPM) prescription and to analyze the relationship between psychopathology and seizure freedom. We analyzed the data on 103 patients who developed psychiatric disorders during TPM therapy. Forty-six patients developed an affective disorder, 22 aggressive behavior, 16 psychosis, 11 anxiety, and 8 personality changes such as anger, agitation, and hostile behavior. Patients with psychosis were more likely to be seizure-free during psychopathology, to receive psychotropic drug prescription, and to be admitted to hospital. In general, patients seizure-free during psychopathology were more likely to have a diagnosis of idiopathic generalized epilepsy, to be in co-therapy with vigabatrin, and to remit after drug reduction. We observed that psychopathology was related to seizure control in a subgroup of patients. The role of forced normalization, interlinked with interactions with other antiepileptic drugs, could be relevant.

The purpose of this paper is to understand the association between antiepileptic drugs (AEDs), patient characteristics, changes in seizure pattern and emergent psychiatric disorder, i.e. psychosis or affective disorder. To this end we carried out a retrospective casenote study on 89 patients who developed psychiatric symptoms during treatment with topiramate, vigabatrin or tiagabine. The psychiatric problem was either an affective or a psychotic disorder (not including affective psychoses). It was discovered that 99% of the patients suffered from complex partial seizures with or without secondary generalization. More than half were on polytherapy with two or more other AEDs. Nearly two-thirds had a previous psychiatric history. There was a strong association between the type of previous psychiatric illness and the type of emerging psychiatric problem, both for psychoses and for affective disorders. Patients on vigabatrin had an earlier onset of epilepsy and more neurological abnormalities than those on topiramate. Those patients on lower doses had a shorter interval between the start of the AED therapy and the onset of the psychiatric problem. A seizure-free period was observed in more than half of the patients before they developed the psychiatric symptoms, and of these more were likely to develop a psychosis rather than an affective disorder. There seemed to be an association of suppression of right-sided seizures and the onset of the psychiatric problem. The conclusions drawn were that patients with a previous history of psychosis or affective disorder tended to develop the same psychiatric problem with new AEDs. Those with a seizure-free period before the onset of the psychiatric problem were more likely to develop a psychosis than an affective disorder.

To report a case of weight loss and mood stabilization in a patient being treated with the antiepileptic drug topiramate.. A 37-year-old obese white woman with affective instability and obesity was being treated with adjunctive topiramate therapy. The patient lost 10 kg over 10 weeks of treatment with topiramate and improved clinically, as evidenced by a reduction in the number of times that she had to be admitted to a management unit for constant observation, and a decrease in the number of times that mechanical restraints or medication interventions were required for aggressive outbursts. Furthermore, the patient successfully completed two home visits while receiving topiramate therapy and was out of the hospital on her third home visit at the time of this writing.. This case further strengthens previous reports that topiramate may be useful in treating affective disorders as well as inducing weight loss in a patient population in which weight gain is common. The patient discussed in this case report had no acute illnesses or changes in health status, no changes in diet, and no changes in her medications that could have accounted for the sudden weight loss. In addition, the patient's behavior did not improve until topiramate was added as adjunctive therapy of valproic acid, citalopram, and chlorpromazine during an adequate trial period.. Controlled studies need to be performed to evaluate the use of topiramate in the psychiatric population and, in particular, the benefits of topiramate therapy in psychiatric patients with an additional diagnosis of obesity.

Because some anti-epileptic drugs (AEDs) are effective in bipolar affective disorders, the new AED topiramate (TPM) may be effective in psychiatric illnesses. TPM was evaluated in mood disorders refractory to previous therapies including newer AEDs.. Charts of 58 consecutive patients, 39 outpatients (15 males, 24 females) and 19 inpatients (6 males, 13 females) were reviewed. TPM 25 mg. b.i.d. was added to existing therapy and titrated in 50 mg increments every 3-7 days. Improvement was rated on a Likert global assessment scale of marked, moderate, mild, or no improvement or worse, based on quality of sleep, appetite, mood, and concentration.. Of the 58 patients with psychiatric disorders, 44 patients had rapid cycling bipolar disorders characterized by manic, hypomanic, or mixed episodes. Eighteen patients had previously failed to respond to lamotrigine and/or gabapentin in addition to conventional mood stabilizers. Fourteen were Bipolar I, six Bipolar II, and seven mixed, ten patients had cyclothymic disorder, seven had bipolar disorder not otherwise specified. Of the remaining 14 patients, nine had schizoaffective disorder, three patients had dementia and two had psychosis. Mean duration of TPM treatment was 16.0 weeks; mean TPM dosage approximately 200 mg/day. Thirty-six of 58 (62%) patients exhibited marked or moderate improvement, usually within days or weeks. Twenty-three of 44 (52%) patients with bipolar affective disorders showed marked or moderate improvement. Minimal/no improvement was observed in 16; six were rated as worse. Adverse events included delirium in one patient with Bipolar Disorder Type I who overmedicated with TPM (800 mg) and tranylcypromine sulfate (170 mg) combined with alcohol. Other adverse effects were minor and included: paresthesias, somnolence, fatigue, impaired concentration and memory, nausea, and diarrhoea.. This study was performed in a nonrandom open and retrospective fashion. Therefore, any findings are limited by the design of this study.. TPM may be useful in patients with mood disorders unresponsive to traditional therapy and warrants further clinical investigation.
