Background: Autonomic dysfunction can precede the onset of motor symptoms in Parkinson's disease and are very disabling, but often overlooked. Objective: This study was done to assess the presence of autonomic symptoms in PD; evaluate any gender differences and association of autonomic dysfunction with fatigue and quality of life. Methods: Demographic profile and disease characteristics of PD patients were assessed. Autonomic symptoms were evaluated by SCOPA-AUT, fatigue by FSS, and QOL with PDQ-39 in patient's vernacular language. Patients with SCOPA-AUT score ≥9 were considered as having autonomic impairment. Gender variation in the involvement of different domains were analyzed along with the risk factors for autonomic dysfunction. Results: Among 94 patients, 59 (63%) had autonomic dysfunction. All SCOPA domains showed significant impairment in PD. Nocturia (69.14%) and constipation (52.12%) constituted most frequent symptoms in our cohort. Mean urinary (7.89 vs. 6.05) and sexual (1.47 vs. 0.42) domain scores were significantly (P < 0.05) higher in males while cardiovascular dysfunction (0.81 vs. 1.64) was predominant in females. Patients with autonomic dysfunction had longer duration of disease (P = 0.033), severe disease (P = 0.0001) with higher UPDRS (P = 0.001). Autonomic symptoms correlated significantly (P < 0.0001) with Fatigue (r = 0.60) also. Patients with autonomic dysfunction had poor QOL (r = 0.67) and mobility, activities of daily living, emotional well-being, stigma, cognition, communication, and bodily-discomfort dimensions were worst affected (P < 0.05). Conclusions: There was a significant variation of autonomic symptoms with gender. Disease severity and duration were significant risk factors for autonomic dysfunction. Also there was a strong co-relation of fatigue and poor QOL with autonomic dysfunction.

Background: Both Impulse-control disorders and related behaviours (ICD-RB) and restless leg syndrome (RLS) are relatively common in patients with Parkinson’s disease, but little is known are they related or independent complications of dopaminergic therapy. The aim of this study was to determine the correlation between ICD-RBs and RLS and also, to determine the associated significant psycho-behavioural profile of RLS patients in presence of ICD-RBs. Methods: PD who visited neurology OPD were screened for the presence of addictive behaviors, alcohol and substance abuse, ICDs including Impulse control disorders not elsewhere classified with the help of a QUIP questionnaire. RLS was evaluated by diagnostic criteria set by the International RLS study group. To evaluate the association of RLS and ICDs, cohort was divided into groups of patients who had both ICD and RLS, ICD with no RLS, RLS with no ICD and no ICD or RLS. Results: Among 122 PD patients who visited OPD, 95 eligible were included in the study. Out of these 95 patients, 51 (53.6%) had at least one ICD-RB and 18 (18.9%) had RLS. ICD-RB in decreasing order of frequency were compulsive medication (47.4%), compulsive eating (29.4%), compulsive buying (17.6%), gambling (11.7%), hypersexuality (3.9%), and others (29.8%). Among 18 patients with RLS, 12 (66.7%) were associated with at least one ICD-RB. The compulsive behaviours significantly associated with PD-RLS group were gambling (27.8%), followed by compulsive eating (44.2%). While comparing disease characteristics, PD-ICD/RLS patients had statistically significant disease duration ( p 0.007) and higher LEDD (p 0.004). Other demographic and socioeconomic features did not reveal any differences between the groups. Conclusion: 11% of PwPD can have co-occurrence of RLS and ICD-RBs. Circadian fluctuation in levels of dopamine release on the background of hyper-dopaminergic state produces waves of crest and trough, which may be possible for this behavioral profile. Long-term dopaminergic treatment or degenerative process itself may be the cause leading to emergence of both RLS and ICD-RBs in PD patients.

Neuroleptic malignant syndrome (NMS) is a rare and rapidly progressive syndrome with mortality rate of 5.6%. The spectrum of onset, progression and outcome is heterogeneous and is associated with number of risk factors. In our case series, we entail the triggers, hospital course and outcome of five interesting in-patient cases that were admitted to our service in a tertiary care hospital in Northern India. This case series is to highlight the first ever reported case of NMS triggered by levosulpiride administration, along with one of the few first cases of NMS after programming of DBS, hypothyroid disorders, levodopa readjustment and selective basal ganglia and cerebellar injury following the hyperthermic syndrome. This is also to bring to attention of clinicians worldwide the atypical risk factors of NMS, and stress the importance of staying vigilant for the same by frequent follow-ups and high degree of clinical suspicion. We also aim to generate epidemiological data about these atypical triggers.
