Use of modafinil in spastic cerebral palsy.

After an initial patient with cerebral palsy had an apparent dramatic reduction in spasticity when placed on modafinil, a pilot study was undertaken in 10 pediatric patients to confirm or refute the benefit of modafinil in cerebral palsy. Nine of 10 patients completed the 1-month treatment period. The study patients were treated with 50 or 100 mg of modafinil once daily in the morning. An assessment was made at baseline and at 1 month on treatment. All patients had a clinical examination, Modified Ashworth Scale scores (spasticity) determined by a physical therapist, and videotaping of ambulation. In comparing visit 1 (baseline) and visit 2 (on treatment), statistically significant improvement in the modified Ashworth Scale scores was noted in seven of the nine patients completing the study (P = .0080). A blinded review of the videotapes did not show statistically significant differences in ambulation, but the speed (ft/sec) of gait improved in six of the nine patients (P = .0192). In this study, modafinil, a newly released central stimulant for narcolepsy, showed benefit in treating spasticity in patients with cerebral palsy. A second larger, placebo-controlled, double-blinded trial is planned to confirm these initial results and observations. Modafinil appears to benefit spastic cerebral palsy by a yet to be determined mechanism; however, a primary effect of modafinil on brainstem structures is hypothesized to reduce spasticity of central origin.

Retrospective review of modafinil use for cerebral palsy.

A retrospective review was undertaken at Texas Tech University Health Sciences Center regarding the use of modafinil for the treatment of spasticity associated with cerebral palsy. Neurology clinic records were reviewed from January 1, 2000, until October 1, 2001. Thirty pediatric patients with cerebral palsy were identified who were treated empirically with modafinil during this time period. Twenty-three (76%) patients reported diminished spasticity with treatment, which was confirmed by physical examination; these patients had improved joint mobility. Seventeen (56%) patients continued treatment with modafinil by the end of the formal review period (September 30, 2001). Twenty-three percent (seven) of the patients stopped taking modafinil during the study owing to one of the following: decreased sleep time (four), decreased appetite (one), hyperactivity, and irritability (two). Thus, this retrospective review shows a reduction in spasticity from cerebral palsy, with only minor and reversible side effects noted from modafinil. A blinded, crossover study using modafinil for spastic cerebral palsy is planned.

Modafinil for remitted bipolar depression with hypersomnia.

OBJECTIVE: To report 2 cases of bipolar disorder with recent depression in remission with prominent residual hypersomnia, responding well to the addition of the psychostimulant modafinil. CASE SUMMARIES: Two patients with bipolar disorder with recent depressive episodes in remission are presented. Despite the absence of prominent depressive symptoms, both patients had significant hypersomnia, with scores ranging from 15 to 20 (maximum 24) on the Epworth Sleepiness Scale. The addition of modafinil to their medication regimen resulted in a decrease in hypersomnia and improvement in their level of functioning. DISCUSSION: This is the first report (MEDLINE search, October 7, 2003) demonstrating the use of modafinil in the treatment of hypersomnia in bipolar disorder while mood symptoms were in remission. Hypersomnia frequently occurs in depressive episodes and can be disabling when severe. The patients had optimal mood stabilization with mood stabilizers and antidepressants, but continued to experience excessive daytime sleepiness. Conventional stimulants were not considered because of the risk of triggering mania. The addition of the selective psychostimulant modafinil resulted in significant improvement in the hypersomnia, with improvement in functioning. No adverse effects or mood changes were noted. CONCLUSIONS: Modafinil may be a well-tolerated and effective alternative to conventional stimulants in the treatment of hypersomnia, especially in bipolar disorder, where there is considerable risk of switch to mania with stimulant medications. Modafinil may be useful even when depressive symptoms are not prominent.

Modafinil: new indications for wake promotion.

In January 2004, the wake-promoting agent, modafinil, was approved in the US for the treatment of excessive sleepiness (ES) associated with obstructive sleep apnoea/hypopnoea syndrome (OSAHS) and shift-work sleep disorder (SWSD), representing an expansion of its labelling from the initial indication for ES associated with narcolepsy. A total of five randomised, placebo-controlled studies in these three disorders showed statistically significant benefits on various objective measures and subjective estimates of ES, including the Multiple Sleep Latency Test, Maintenance of Wakefulness Test, Epworth Sleepiness Scale and Karolinska Sleepiness Scale. Significant improvement was also seen in overall clinical condition (on the Clinical Global Impression of Change) and measures of sustained attention and reaction time (on the Psychomotor Vigilance Task). The clinical efficacy of modafinil, combined with improved safety over CNS stimulants, has made it the most prescribed medication for the treatment of ES associated with narcolepsy. Modafinil is the only medication approved for ES associated with OSAHS and SWSD (for OSAHS, it is indicated as an adjunct to standard treatments for the under-lying obstruction). Unlike many other medications used for ES, modafinil is not known to be abused. The most common adverse event reported in clinical studies was headaches; most were transient and mild-to-moderate in severity. Modafinil also has the potential for interactions with other drugs metabolised via cytochrome P450 enzyme pathways. Potential obstacles to the use of modafinil include an under-recognition of ES and its consequences. Increased education, both of the public and the medical community, should improve the recognition and therapy of ES.

Adjunctive modafinil at initiation of treatment with a selective serotonin reuptake inhibitor enhances the degree and onset of therapeutic effects in patients with major depressive disorder and fatigue.

BACKGROUND: Benefit from selective serotonin reuptake inhibitor (SSRI) treatment in major depressive disorder (MDD) usually takes several weeks. Typically, a third of patients achieve remission and roughly half achieve response with acute treatment. This open-label study evaluated the efficacy and safety of modafinil treatment initiated with an SSRI in patients with MDD and fatigue. METHOD: Twenty-nine patients with DSM-IV MDD, free from antidepressant therapy (> or = 4 weeks), were administered modafinil (titrated to 200 mg/day) and fluoxetine or paroxetine (20 mg/day) for 6 weeks. Assessments included the 21-item Hamilton Rating Scale for Depression (HAM-D), Structured Interview Guide for the HAM-D (SIGH-D), Fatigue Severity Scale (FSS), and Epworth Sleepiness Scale (ESS). The SIGH-D ratings were videotaped and rated by an independent rater masked to the visit schedule. Data were collected from August 2002 through March 2003. RESULTS: Modafinil combined with an SSRI at treatment initiation significantly improved mean total SIGH-D scores within 1 week (-9.3, p <.001), and this improvement was progressive throughout the study (-21.2 at week 6, p <.001). Forty-two percent (11 of 26) and 79% (19 of 24) of patients were responders, and 39% (10 of 26) and 58% (14 of 24) of patients were remitters (HAM-D) by week 2 and week 6, respectively. Adjunct modafinil rapidly and significantly reduced fatigue (FSS score reduction from baseline = 0.7 at week 1, p <.01) and improved wakefulness (ESS score reduction from baseline = 3.6 at week 1, p <.01). The combination caused few adverse events, with nausea and headache being the most common. CONCLUSION: Modafinil combined with an SSRI at treatment initiation may enhance the onset and degree of symptom benefit in patients with MDD and fatigue. Treatment with adjunct modafinil was generally well tolerated, with most adverse effects being mild or moderate in severity.

Modafinil vs. caffeine: effects on fatigue during sleep deprivation.

INTRODUCTION: The extent to which modafinil and caffeine reverse fatigue effects (defined as performance decrements with time on task) during total sleep deprivation was investigated. METHODS: There were 50 healthy young adults who remained awake for 54.5 h (06:30 day 1 to 13:00 day 3). A 10-min vigilance test was administered bi-hourly from 08:00 day 1 until 22:00 day 2. At 23:55 day 2 (after 41.5 h awake), double-blind administration of one of five drug doses (placebo; modafinil 100, 200, or 400 mg; or caffeine 600 mg; n = 10 per group) was followed by hourly testing from 00:00 through 12:00 day 3. Response speed (reciprocal of reaction time) across the 10-min task (by 1-min block) was analyzed prior to and after drug administration. RESULTS: A fatigue effect (response speed degradation across the 10-min task) was exacerbated by sleep deprivation and circadian rhythmicity. Prior to the drug, this effect was maximal between 08:00 and 12:00 day 3 (24-28 h sleep deprivation). Modafinil 400 mg attenuated fatigue in a manner comparable to that seen with caffeine 600 mg; these effects were especially salient during the circadian nadir of performance (06:00 through 10:00); modafinil 200 mg also reversed fatigue, but for a shorter duration (3 min) than modafinil 400 mg (8 min) or caffeine 600 mg (6 min). DISCUSSION AND CONCLUSIONS: Time-on-task effects contributed to the performance degradation seen during sleep deprivation; effects which were reversed by caffeine and, at appropriate doses, by modafinil. Because the duration of efficacy for reversing time-on-task effects was shorter at lower drug dosages, the latter must be considered when determining the appropriate dose to use during sustained operations.

Long-term efficacy and safety of modafinil (PROVIGIL((R))) for the treatment of excessive daytime sleepiness associated with narcolepsy.

Objectives: To assess the long-term efficacy and safety of modafinil in patients with excessive daytime sleepiness (EDS) associated with narcolepsy.Background: Modafinil has been shown to be effective and well tolerated for treating EDS associated with narcolepsy in two large-scale, well-controlled, 9-week clinical trials.Methods: Four hundred and seventy eight adult patients with a diagnosis of narcolepsy who had completed one of two 9-week, double-blind, placebo-controlled, multicenter, clinical trials of modafinil were enrolled in two 40-week, open-label, extension studies. A flexible-dose regimen (i.e. 200, 300, or 400 mg daily) was followed in one study. In the second study, patients received 200 mg/day for 1 week, followed by 400 mg/day for 1 week. Investigators then prescribed either 200- or 400-mg doses for the duration of the study. Efficacy was evaluated using Clinical Global Impression of Change (CGI-C) scores, the Epworth Sleepiness Scale (ESS), and the 36-item Medical Outcomes Study health survey (SF-36). Adverse events were recorded. Data from the two studies were combined.Results: The majority of patients ( approximately 75%) received 400 mg of modafinil daily. Disease severity improved in >80% of patients throughout the 40-week study. At weeks 2, 8, 24, and 40, disease severity was 'much improved' or 'very much improved' in 49, 58, 59, and 58% of patients, respectively. The mean (+/-SEM) ESS score improved significantly from 16.5+/-0.2 at open-label baseline to 12.4+/-0.2 at week 2 and remained at that level through week 40 (P<0.001). Quality of life scores at weeks 4, 8, 24, and 40 were significantly improved versus open-label baseline scores for six of the eight SF-36 domains (P<0.001). The most common treatment-related adverse events were headache (13%), nervousness (8%), and nausea (5%). Most adverse events were mild to moderate in nature. A total of 341 patients (71%) completed the studies. Forty-three patients (9.0%) discontinued treatment because of adverse events.Conclusions: Modafinil is effective for the long-term treatment of EDS associated with narcolepsy and significantly improves perceptions of general health. Modafinil is well tolerated, with no evidence of tolerance developing during 40 weeks of treatment.

Modafinil for fatigue in MS: a randomized placebo-controlled double-blind study.

OBJECTIVE: To assess whether modafinil, a wakefulness-promoting agent, is useful for fatigue in patients with multiple sclerosis (MS). METHODS: Patients with MS with stable disability, and a baseline score of 45 or more on the Modified Fatigue Impact Scale (MFIS), were eligible for the 5-week randomized, double-blind, placebo-controlled, parallel group study. The initial daily dose of modafinil was 200 mg for 1 week. Depending on tolerance, the dose was increased by 100 mg every week up to 400 mg/day and remained unchanged between day 21 and day 35. The primary outcome variable was the change of MFIS score at day 35. RESULTS: A total of 115 patients with MS were enrolled in the study and in the intention to treat analysis. The mean MFIS score at baseline was 63 +/- 9 in the placebo group and 63 +/- 10 in the modafinil group. MFIS scores improved between day 0 and day 35 in both placebo-treated and modafinil-treated groups, but no significant difference was detected between the two groups. There was no major safety concern. CONCLUSIONS: There was no improvement of fatigue in patients with multiple sclerosis treated with modafinil vs placebo according to the Modified Fatigue Impact Scale.

Comparison of the single-dose pharmacokinetics and tolerability of modafinil and dextroamphetamine administered alone or in combination in healthy male volunteers.

An open-label, randomized, crossover study was performed in healthy male volunteers to evaluate the potential pharmacokinetic and pharmacodynamic interactions and tolerability of single oral doses of modafinil (200 mg) and dextroamphetamine (10 mg). Blood samples were collected for determination of plasma levels of modafinil, the acid and sulfone metabolites of modafinil, and dextroamphetamine at intervals through 48 hours after administration for each treatment. Vital signs (blood pressure and pulse rate) were measured through 48 hours, and electrocardiograms were measured through 24 hours after administration. Pharmacokinetic parameters were determined using noncompartmental methods. The data collected in this study of 24 healthy volunteers suggest that concomitant administration of single oral doses of modafinil and dextroamphetamine has no clinically significant effects on the pharmacokinetic profile of either agent. Although there was a slightly greater incidence of adverse events when modafinil and dextroamphetamine were administered together, the concomitant administration of the two drugs was well tolerated.

Differential enhancement of dialysate serotonin levels in distinct brain regions of the awake rat by modafinil: possible relevance for wakefulness and depression.

The present in vivo microdialysis study evaluates the possible existence of a differential regulation of serotonergic transmission by the antinarcoleptic drug modafinil [(diphenyl-methyl)-sulfinyl-2-acetamide; Modiodal] among various brain regions of the awake rat. The results show that, in the cerebral cortex, the central amygdala, and the dorsal raphe nucleus, modafinil in the dose range of 10-100 mg/kg i.p. dose-dependently increases dialysate serotonin (5-HT) levels. In other brain areas, such as the medial preoptic area and the posterior hypothalamus, the modafinil-induced increase in dialysate 5-HT levels is observed only at tenfold higher doses (100 mg/kg), 10-30 mg/kg being ineffective. Together these data suggest that, in the frontal cortex, the amygdala, and the dorsal raphe, modafinil is more potent in enhancing extracellular 5-HT levels and presumably 5-HT transmission than in the medial preoptic area and the posterior hypothalamus. In view of the role of ascending 5-HT pathways in arousal and depression, it seems likely that the antinarcoleptic drug modafinil may also have an antidepressant potential in addition to its wakefulness-promoting action, both actions involving enhancement of 5-HT neurotransmission.

The detection of modafinil and its major metabolite in equine urine by liquid chromatography/mass spectrometry.

A method has been developed for the detection of modafinil and its major metabolite, modafinil acid, in equine urine by solid-phase extraction and positive ion electrospray ionisation liquid chromatography/mass spectrometry. The method has been applied to the analysis of equine urine samples obtained after the oral administration of modafinil. Modafinil acid was the major component in the urine, and was detected up to 4 days post-administration. Unchanged modafinil was present at substantially lower concentrations, and was detected for only 24 hours.

Evidence for a preventive action of the vigilance-promoting drug modafinil against striatal ischemic injury induced by endothelin-1 in the rat.

We have studied the ability of the vigilance-promoting drug modafinil to counteract the ischemic lesion produced by a unilateral microinjection of endothelin-1 (ET-1) in the neostriatum of the rat using a combined morphometrical, biochemical, cardiovascular and behavioral analysis. ET-1 was injected unilaterally into the neostriatum. The ET-1-induced lesion volume, which was determined by a computer-assisted morphometrical analysis, was reduced by the 7-day modafinil treatment (10, 30, and 100 mg/kg i.p.) in a dose-related way. Modafinil also produced a dose-related counteraction of the ET-1-induced increase of perfusate lactate levels, as determined by intrastriatal microdialysis without affecting the ET-1 induced reduction of striatal blood flow, as determined by laser-Doppler flowmetry. The ipsilateral rotational behavior induced by apomorphine in the ET-1-lesioned rats was reduced dose-dependently by modafinil treatment. Thus, morphological, neurochemical, and behavioral evidence that the putative ischemic striatal injury induced by microinjection of ET-1 in the rat neostriatum is counteracted in a dose-dependent way by modafinil treatment has been obtained. The mechanism does not appear to involve an increase in striatal blood flow. It is instead speculated that its powerful preventive action in striatal ischemic injury may be related to a reduced anaerobic metabolism.

Awakening properties of modafinil: effect on nocturnal activity in monkeys (Macaca mulatta) after acute and repeated administration.

Single oral administration of modafinil (16-64 mg/kg) in monkeys induced an increase in nocturnal activity and in behavioural arousal without stereotyped behaviour. Modafinil-induced increase in nocturnal activity was prevented by the centrally acting alpha 1 adrenoceptor antagonist prazosin. After repeated oral administration of modafinil, b.i.d. for 5 days, nocturnal activity was still increased, but was lower than after a single administration; the gradual decrease appeared on the second night. No rebound of sleep and no residual effect on night 5 (when modafinil was administered for 4 days and placebo on day 5) were seen after the withdrawal of the drug. Therefore, modafinil appeared to produce strong behavioural stimulation and awakening in a non-human primate species, after single, as well as after repeated administration, without other obvious side-effects (no sign of anxiety, no behavioural trouble). These awakening properties involved a modulation (stimulation) of a central alpha 1 adrenergic system.

Open-label study of adjunct modafinil for the treatment of patients with fatigue, sleepiness, and major depression treated with selective serotonin reuptake inhibitors.

Despite the efficacy of selective serotonin reuptake inhibitors (SSRIs) in the treatment of major depression, a significant number of patients show partial or no remission of symptoms. Some evidence suggests that psychostimulant augmentation may be helpful in treating patients with residual symptoms of depression. The efficacy of modafinil in augmenting SSRIs in depressed patients with residual fatigue or excessive daytime sleepiness has yet to be systematically investigated. In a series of 25 patients with major depressive disorder, according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, who showed significant residual symptoms after an adequate SSRI trial (12 wk) and who were evaluated according to the Fatigue Severity Scale (FSS), subjects with scores > or = 4 were given open-label modafinil augmentation for a minimum of an additional 6 wk. Treatment response was assessed prospectively with the FSS, the Epworth Sleepiness Scale (ESS), and the Hamilton Rating Scale for Depression (HAM-D) during the first visit and at the second and sixth weeks. Twenty-one of 25 patients in this series who were treated with modafinil and SSRIs completed the 6-wk augmentation trial. At end-point assessment, all patients showed significant improvement in fatigue and sleepiness in FSS and ESS scores, as well as in HAM-D scores (P<.01). In the second week, 29.4% of patients had a HAM-D score <7, which was defined as remission; this rate was 64.7% in the sixth week. The rate of patients whose HAM-D score dropped by more than 50%, defined as responders to treatment, was 41.1% and 76.4% in the second and sixth weeks, respectively. Results of this preliminary, open-label trial suggest that modafinil may be effective in augmenting ongoing SSRI treatment for a portion of patients with major depression who have residual fatigue and sleepiness. Larger, placebo-controlled trials appear warranted to investigate the clinical efficacy and tolerability of modafinil augmentation of SSRI treatment in these patients.

The effect of modafinil on counter-regulatory and cognitive responses to hypoglycaemia.

AIMS/HYPOTHESIS: Our hypothesis is that reducing release of the inhibitory neurotransmitter gamma-aminobutyric acid (GABA) with modafinil will enhance symptomatic and hormonal responses to hypoglycaemia. METHODS: Nine healthy men received, in random order, two 100-mg doses of modafinil or placebo, followed by an insulin clamp in which plasma glucose was either reduced stepwise to 2.4 mmol/l or was sustained at euglycaemia (four studies). Catecholamines, symptom scores and cognitive function were measured. RESULTS: Modafinil had no effect on the measured parameters during euglycaemia. During hypoglycaemia, autonomic symptom scores were significantly higher with modafinil (increase at lowest plasma glucose concentration 271.3+/-118.9 vs 211.2+/-80.4/40 min, p=0.019), and the heart rate response was increased (12,928+/-184 vs 6773+/-148 bpm/140 min, p=0.016). Deterioration in performance of two cognitive tasks was reduced: Stroop colour-word test (613+/-204 vs 2375+/-161/65 min, p=0.009) and accuracy of a simple reaction task (11.3+/-1.8 vs 9.4+/-3.7, p=0.039). CONCLUSIONS/INTERPRETATION: We conclude that modafinil improves adrenergic sensitivity and some aspects of cognitive function at hypoglycaemia, possibly by reducing neuronal central GABA concentrations.

Modafinil in treatment of fatigue in multiple sclerosis. Results of an open-label study.

BACKGROUND: Modafinil is a unique wake-promoting agent that is chemically distinct from traditional stimulants. Results of a placebo-controlled study showed it to improve fatigue in multiple sclerosis (MS) at a dose of 200 mg daily, but not at a dose of 400 mg daily. OBJECTIVE: To establish the efficacy, safety and appropriate dose of modafinil in the treatment of fatigue and sleepiness in patients with multiple sclerosis. METHOD: A total of 50 patients diagnosed with MS (mean age 40.4 +/- 10.3 years, 30 females/20 males; MS type: 36 relapsing remitting, 1 primary progressive, 13 secondary progressive; mean disability level 3.8 +/- 1.5 on the Kurtzke EDSS) and complaining of chronic fatigue were enrolled in a prospective 3-month, two-center, open-label study. Efficacy was evaluated with the Fatigue Severity Scale (FSS, score range 0-42), the Epworth Sleepiness Scale (ESS, score range 0-24) and by subjective patient appraisal of change of fatigue, quality of life and overall satisfaction with treatment. Adverse effects (AEs) were recorded throughout the study. Treatment was started with a single daily dose of 100 mg in all patients. In non-responders the dose was increased by 100 mg increments up to a maximum daily dose of 400 mg. RESULTS: Three patients discontinued modafinil because of AEs (nervousness, dizziness). Two patients (4 %) were treated with 50 mg, 25 (50 %) with 100 mg, 21 (42 %) with 200 mg and 2 (4 %) with 300 mg daily. No patient required 400 mg daily. Mean FSS scores were 30.3 +/- 8.5 at baseline and 25.4 +/- 3.7 at 3 months (p < 0.0001). Mean ESS scores were 9.7 +/- 3.9 at baseline and 4.9 +/- 2.9 at 3 months (p < 0.0001). Self-appraisal of change of fatigue showed clear improvement in 41 patients (87.2 %), some improvement in 4 (8.5 %) and no change in 2 (4.3 %). Overall clinical condition was clearly improved in 43 patients (91.5 %), somewhat improved in 1 patient (2.1 %), and unchanged in 3 patients (6.4 %). No patient reported worsening of overall clinical condition. CONCLUSIONS: Treatment with modafinil significantly improves fatigue and sleepiness and is well tolerated by patients with MS. Unlike the higher dose regimen required in narcolepsy, a low-dose regimen of modafinil is effective in MS.

Central alpha 1-adrenergic stimulation in relation to the behaviour stimulating effect of modafinil; studies with experimental animals.

Single administration of the new drug modafinil was followed by an increase in locomotor activity in mice and in nocturnal activity in monkeys. Stereotyped behaviour in mice and rats, and potentiation of amphetamine-induced stereotyped behaviour were not observed; however, at the highest dose used, a slight potentiation of apomorphine-induced stereotyped behaviour was observed in rats. The modafinil-induced increase in locomotor activity in mice was prevented by the centrally acting alpha 1-adrenoceptor antagonists, prazosin and phenoxybenzamine, and by reserpine but not by the mixed dopamine D-1/D-2 antagonist, haloperidol, the dopamine D-2 antagonist, sulpiride, the peripherally acting alpha 1-adrenoceptor antagonist, phentolamine, the alpha 2-adrenoceptor antagonist, yohimbine, the beta-adrenoceptor antagonist, propranolol, or by the catecholamine synthesis inhibitor, alpha-methyl-p-tyrosine. Likewise, the modafinil-induced increase in nocturnal activity in monkeys was prevented by prazosin. Interestingly, modafinil did not produce obvious peripheral sympathetic effects in mice and rats (no salivation, no contraction of the pilomotor muscles, slight mydriasis only at high doses). Therefore, modafinil appears to produce a strong stimulating effect in rodents and in primates. These effects could be linked to modulation (stimulation) of central alpha 1-adrenoceptors unaccompanied by peripheral sympathetic effects, which is unexpected.

The effect of modafinil on self-esteem in spinal cord injury patients: a report of 2 cases and review of the literature.

We report on 2 cases of the effect of modafinil on the self-esteem of patients with spinal cord injury (SCI). The first patient was a 33-year-old man with history of polysubstance abuse and a C6 American Spinal Injury Association (ASIA) grade A injury, who presented for follow-up to the outpatient rehabilitation clinic for depression, decreased motivation, and lowered self-esteem. The patient had tried a selective serotonin reuptake inhibitor (SSRI) without success, and reported increasing social and legal stressors. Within 1 month of starting on modafinil, he reported increased self-esteem and motivation, as well as decreased self-consciousness. The second patient was a 36-year-old woman with history of depression and a T11 ASIA grade A injury. She tried various SSRIs for depression and adjustment issues before she was started on modafinil. She lost weight and became more assertive and less self-conscious within 1 month after starting on modafinil. These 2 cases suggest that modafinil should be studied as a therapeutic option for treating lowered self-esteem in patients with SCI.
