1.  Head banging persisting during adolescence: A case with polysomnographic findings 
Head banging is a sleep-related rhythmic movement disorder of unknown etiology. It is common during infancy; however, available literature suggests that prevalence decreases dramatically after childhood. We report the case of a 16-year-old male who presented with head banging. The symptoms were interfering with his functioning and he had been injured because of the same in the past. We are presenting the video-polysomnographic data of the case. Possible differential diagnoses, etiology, and treatment modalities are discussed. The boy was prescribed clonazepam and followed up for 3 months. Parents did not report any episode afterward.

2.  What patients do to counteract the symptoms of Willis-Ekbom disease (RLS/WED): Effect of gender and severity of illness 
Objectives:
This study was carried out to assess different counteracting strategies used by patients with idiopathic Willis-Ekbom disease (RLS/WED). Whether these strategies were influenced by gender or disease severity was also assessed.
Materials and Methods:
A total of 173 patients of idiopathic RLS/WED were included in this study. Their demographic data was recorded. Details regarding the RLS/WED and strategies that they used to counteract the symptoms were asked. The severity of RLS/WED was measured with the help of the Hindi version of international restless legs syndrome severity rating scale. They were asked to provide the details regarding the relief obtained from all the strategies they used on three-point scale: no relief, some relief, and complete relief.
Results:
Of the patients, 72% were females. Mean age of the subjects in this study was 39.6 ± 12.6 years, and male subjects were older than females. Four common strategies were reported by the patients to counter the sensations of RLS/WED: moving legs while in bed (85.5%), asking somebody to massage their legs or massaging legs themselves (76.9%), walking (53.2%), and tying a cloth/rope tightly on the legs (39.3%). Of all the patients who moved their legs, 6.7% did not experience any relief, 64.2% reported some relief, and 28.4% reported complete relief. Similarly, of all the patients who used “walking” to counteract symptoms, 50% reported complete relief, 44.5% reported some relief, and the rest did not experience any relief. Many of these patients reported that massage and tying a cloth/rope on legs brought greater relief than any of these strategies. Tying cloth on the leg was more common among females as compared to males (45.9% females vs. 23.5% males; χ2 = 7.54; P = 0.006), while patients with moderately severe to severe RLS/WED reported “moving legs in bed” (79.3% in mild to moderate RLS/WED; 91.8% in severe to very severe RLS; χ2 = 5.36; P = 0.02).
Conclusion:
Patients with RLS/WED use a variety of strategies to counteract symptoms. These strategies may be influenced by gender, disease severity, and cultural practices.

3.  REM sleep behavior disorder in Parkinson's disease: A case from India confirmed with polysomnographic data 
Rapid eye movement (REM) sleep behavior disorder is a condition characterized by dream enactment. This condition may accompany neurodegenerative disorders. However, only a few reports from India are available, that too, without any polysomnographic evidence. We are reporting a case of REM sleep behavior disorder with polysomnographic evidence.

5.  Prevalence of restless leg syndrome in subjects with depressive disorder 
Indian Journal of Psychiatry  2013;55(1):70-73.
Background:
Restless legs syndrome (RLS) is known to be associated with depression. We hypothesized that RLS in depression is linked to the severity, duration, and frequency of depressive episodes.
Materials and Methods:
Subjects fulfilling DSM-IV-TR criteria of depressive disorders were included in this study after seeking informed consent. Using structured interview of MINI-Plus their demographic data and history were recorded. Severity of depression was assessed with the help of HAM-D. Insomnia was diagnosed following ICSD-2 criteria. RLS was diagnosed according to IRLSSG criteria. Descriptive statistics, Chi-square test, independent sample t test and MANOVA were computed with the help of SPSS v 17.0.
Results:
RLS was reported by 31.48% of sample. There was no gender difference in prevalence of RLS (X2 =0.46; P=0.33). There was no difference in the age , total duration of depressive illness and number of depressive episodes between RLS and non-RLS groups (F=0.44; P=0.77; Wilk's Lambda=0.96). The HAM-D score was higher in the non-RLS group (P=0.03). Onset of RLS symptoms was not related to onset of depressive symptoms.
Conclusion:
RLS is prevalent in depressive disorder. However, onset of RLS is unrelated to age and number or duration of depressive disorders.

6.  Restlessness in right upper limb as sole presentation of restless legs syndrome 
Restless legs syndrome (RLS) rarely affects the upper limb during the initial course of disease. We present a patient who complained of symptoms suggesting RLS in the right upper limb as the sole manifestation of illness. Bilateral cervical ribs and depression were co-incidental findings. Patient responded well to dopaminergic therapy.

7.  Primary headaches in restless legs syndrome patients 
Annals of Indian Academy of Neurology  2012;15(Suppl 1):S104-S108.
Earlier studies conducted among migraineurs have shown an association between migraine and restless legs syndrome (RLS). We chose RLS patients and looked for migraine to exclude sample bias.
Materials and Methods:
99 consecutive subjects of idiopathic RLS were recruited from the sleep clinic during four months period. Physician diagnosis of headache and depressive disorder was made with the help of ICHD-2 and DSM-IV-TR criteria, respectively. Sleep history was gathered. Severity of RLS and insomnia was measured using IRLS (Hindi version) and insomnia severity index Hindi version, respectively. Chi-square test, one way ANOVA and t-test were applied to find out the significance.
Results:
Primary headache was seen in 51.5% cases of RLS. Migraine was reported by 44.4% subjects and other types of ‘primary headaches’ were reported by 7.1% subjects. Subjects were divided into- RLS; RLS with migraine and RLS with other headache. Females outnumbered in migraine subgroup (χ2=16.46, P<0.001). Prevalence of depression (χ2=3.12, P=0.21) and family history of RLS (χ2=2.65, P=0.26) were not different among groups. Severity of RLS (P=0.22) or insomnia (P=0.43) were also similar.
Conclusion:
Migraine is frequently found in RLS patients in clinic based samples. Females with RLS are prone to develop migraine. Depression and severity of RLS or insomnia do not affect development of headache.

8.  Translation and validation of International Restless Leg Syndrome Study Group rating scale in Hindi language 
Objectives:
The objective of this study is to translate and validate the International Restless Leg Syndrome Study Group rating scale (IRLS) in Hindi language.
Materials and Methods:
Thirty one consecutive patients diagnosed of Restless Leg Syndrome (RLS) were included in the study. Control group comprised of 31 subjects not having any symptom of RLS. The scale was procured from MAPI research trust; and, permission for the translation was sought. The translation was done according to the guidelines provided by the publisher. After translation, final version of the scale was applied in both the groups to find out the reliability and clinical validity.
Results:
RLS group had a predominance of females, and they were younger than the male counterparts (Age=36.80 ± 10.46 years vs 45.18 ± 8.34 years; t=2.28; P=0.03). There was no difference in the mean age between groups (RLS=39.77 ± 10.44 years vs Non RLS=38.29 ± 11.29 years; t=-0.53; P=0.59). IRLS scores were significantly different between both groups on all items (P<0.001). Translated version showed high reliability (Cronbach's alpha=0.86). IRLS scores were significantly different between both groups on all items (P<0.001).
Conclusion:
Hindi version of IRLS is reliable and a clinically valid tool that can be applied in Hindi speaking population.
