Abstract
Objective Levodopa is the first-line treatment for patients with Parkinson's disease (PD). However, only a few studies have focused on the tolerance of this drug in older patients with PD in the early and middle stages. Therefore, this study aimed to explore the effects of different levodopa doses on blood pressure (BP) in this subpopulation. Methods This cohort analysis enrolled 83 patients. The levodopa challenge test was used to evaluate drug responsiveness. After at least 12 h following anti-PD drug discontinuation, patients' BPs were measured in a lying position, after 1 min standing, and after 3 min standing, in "off state" and best "on state." Results BP in the 250 mg and 375 mg levodopa/benserazide groups decreased significantly in the lying and standing positions. The 3-min standing-position systolic BP was significantly influenced by the dose of levodopa/benserazide. However, no statistical change was observed in the 125 mg group. The postural-mediated systolic BP disparity was significant at 3 min in the upright position. Nineteen (incidence, 22.9%) and Twenty-five patients (incidence, 30.1%) developed complications of orthostatic hypotension (OH) in the "off state" and best "on state," respectively. Mild cognitive impairment was a risk factor for OH occurrence in the "off state." The OH occurrence in the best "on state" was associated with OH in the "off state" and urinary incontinence. Conclusion Our findings suggest that 250 mg or more of levodopa/benserazide could significantly reduce BP and orthostatic effect in older patients with PD in the early and middle stages. Therefore, they should routinely monitor their BP. Trial registration number ChiCTR2200055707.

Abstract
Parkinson disease (PD) is associated with a variety of motor and non-motor clinical manifestations, including cardiovascular autonomic dysfunction. Neurogenic orthostatic hypotension (nOH) is a potentially serious manifestation of cardiovascular sympathetic failure that occurs in approximately 30% of patients with PD. Here we review the pathophysiology and effects of the condition as well as treatment considerations for patients with PD and nOH. Screening for nOH using orthostatic symptom questionnaires, orthostatic blood pressure measurements, and specialized autonomic testing is beneficial for the identification of symptomatic and asymptomatic cases because cardiac sympathetic denervation and nOH can occur even at early (premotor) stages of PD. Symptoms of nOH, such as orthostatic lightheadedness, in patients with PD, have been shown to adversely affect patient safety (with increased risk of falls) and quality of life and should prompt treatment with non-pharmacologic and, occasionally, pharmacologic measures. Patients with nOH are also at increased risk of supine hypertension, which requires balancing various management strategies. FUNDING: Lundbeck (Deerfield, IL).

Abstract
Background: Hemodynamic perturbations can be anticipated in deep brain stimulation (DBS) surgery and may be attributed to multiple factors. Acute changes in hemodynamics may produce rare but severe complications such as intracranial bleeding, transient ischemic stroke and myocardium infarction. Therefore, this retrospective study attempts to determine the incidence of hemodynamic perturbances (rate) and related risk factors in patients undergoing DBS surgery. Materials and Methods: After institutional approval, all patients undergoing DBS surgery for the past 10 years were recruited for this study. Demographic characteristics, procedural characteristics and intraoperative hemodynamic changes were noted. Event rate was calculated and the effect of all the variables on hemodynamic perturbations was analyzed by regression model. Results: Total hemodynamic adverse events during DBS surgery was 10.8 (0–42) and treated in 57% of cases. Conclusion: Among all the perioperative variables, the baseline blood pressure including systolic, diastolic, and mean arterial pressure was found to have highly significant effect on these intraoperative hemodynamic perturbations.

The range and nature of non-motor symptoms in drug-naive Parkinson's disease patients: a state-of-the-art systematic review. NPJ PARKINSONS DISEASE 2015; 1:15013.

Abstract
Non-motor symptoms (NMS) are a key component of Parkinson’s disease (PD). A range of NMS, most notably impaired sense of smell, sleep dysfunction, and dysautonomia are present from the ‘pre-motor’ phase to the final palliative stage. Theories as to the pathogenesis of PD such as those proposed by Braak and others also support the occurrence of NMS in PD years before motor symptoms start. However, research addressing the range and nature of NMS in PD has been confounded by the fact that many NMS arise as part of drug-related side effects. Thus, drug-naive PD (DNPD) patients provide an ideal population to study the differences in the presentation of NMS. The aim of this paper is therefore to systematically review all the available studies of NMS in DNPD patients. We believe this is the first review of its kind. The current review confirms the increasing research being conducted into NMS in DNPD patients as well as the necessity for further investigation into less-studied NMS, such as pain. Moreover, the data confirms non-motor heterogeneity among PD patients, and, therefore, further research into the concept of non-motor subtyping is encouraged. The review suggests that the clinical assessment of NMS should be integral to any assessment of PD in clinical and research settings.

Abstract
Orthostatic hypotension (OH) is a common and disabling symptom affecting Parkinson's disease (PD) patients. We present the effect of the different therapies commonly used to manage PD on this clinical manifestation. For this purpose, we describe the relationship between OH and the current treatments employed in PD, such as L-DOPA, dopaminergic agonists, and continuous dopaminergic stimulation therapies. Additionally, we review the therapeutic measures that could be used to ameliorate OH. There are different approaches to deal with this manifestation, including pharmacological and non-pharmacological treatments, although none of them is specifically aimed for treating OH in PD.

Abstract
OBJECTIVES Autonomic symptoms are present in early stages of Parkinson's disease (PD), but evidence on how they are influenced by dopaminergic treatment remains unclear. The aim of this study was to investigate the impact of dopaminergic treatment on autonomic symptoms in early PD in a population-based cohort. METHODS A total of 171 drug-naive patients with PD were investigated at diagnosis and 12 months later. Orthostatic blood pressure was measured, and autonomic symptoms were assessed by a preliminary version of the Movement Disorders Society-sponsored new version of the Unified Parkinson's Disease Rating Scale (range 0-4). RESULTS In the 82% using dopaminergic treatment after 1 year, constipation and orthostatic blood pressure drop increased. There was a tendency towards increased orthostatic dizziness and urinary dysfunction. Dysphagia scores were reduced, and this was associated with higher levodopa-equivalent daily dose. CONCLUSIONS Dopaminergic treatment during the first year after initiation seems to have only a minor impact on autonomic symptoms in early PD. It may increase constipation and orthostatic dizziness, while dysphagia can improve. Autonomic symptoms remained mild after 1 year of dopaminergic treatment.

Parkinsonian single fallers versus recurrent fallers: different fall characteristics and clinical features. J Neurol 2010; 257:1543-51.

Abstract
The study aimed to compare the fall characteristics between parkinsonian single (P-SF) and recurrent fallers (P-RF), and the clinical features among parkinsonian non-fallers (P-NF), P-SF, P-RF and age-matched healthy controls. As many as 72 patients with PD and 74 healthy subjects completed the study. Each subject was evaluated for gait speed, timed up-and-go test, one-leg-stance test, six-minute walk test, five-times-sit-to-stand test, and Activities-specific Balance Confidence (ABC) scale at baseline. Subjects were then followed up for 12 months by telephone interview to record the fall incidence and fall characteristics. Among the PD patients, 12 fell once (P-SF) and 13 fell 2-29 times (P-RF), accounting for a total of 133 falls in the 12-month follow-up period. The most common fall-related activity for both P-SF and P-RF was walking. P-SF fell mostly outdoors due to "tripping", while P-RF mostly fell at home due to "muscle giving way". Clinical measures indicated that P-SF did not differ from P-NF. However, P-RF had significantly longer five-times-sit-to-stand time, shorter 6-min walk distance, and lower ABC score than P-SF. P-RF could be distinguished from P-SF by fall characteristics (i.e. location and perceived causes of falls), and by clinical measures including leg muscle weakness, reduced exercise endurance and increased level of fear of falling. Findings from the present study suggest that P-NF/P-SF and P-RF may require different intervention strategies to prevent future falls.

Abstract
Although extrapyramidal diseases are commonly thought to solely affect the extrapyramidal motor system, nonmotor symptoms such as behavioural abnormalities, dysautonomia, sleep disturbances and sensory dysfunctions are also frequently observed. Autonomic dysfunction as an important clinical component of extrapyramidal disease (idiopathic Parkinson's disease, multiple system atrophy, progressive supranuclear palsy, dementia with Lewy bodies) is often not formally assessed and thus frequently misdiagnosed. Symptoms of autonomic dysfunction in general impact more on quality of life than motor symptoms. Appropriate symptom-oriented diagnosis and symptomatic treatment as part of an interdisciplinary approach can greatly benefit the patient. Unfortunately, double-blind, randomized, controlled studies are scarce with the consequence that most recommendations are not based on the highest level of evidence. This review elaborates a limited overview on the treatment of cardiovascular, gastrointestinal, urogenital and sudomotor autonomic dysfunction in various extrapyramidal syndromes.

Abstract
Symptoms of cardiovascular dysautonomia are a common occurrence in Parkinson's disease (PD). In addition to this dysautonomia as part of PD itself, dysfunction of the autonomic nervous system (ANS) can be triggered as a side-effect of drug treatment interacting with the ANS or - if prominent and early - an indication of a different disease such as multiple system atrophy (MSA). Various diagnostic tests are available to demonstrate autonomic failure. While autonomic function tests can differentiate parasympathetic from sympathetic dysfunction, cardiac imaging can define the pathophysiologically involved site of a lesion. Standard tests such as 24-h ambulatory blood pressure measurements can identify significant autonomic failure which needs treatment. The most frequent and disturbing symptom of cardiovascular autonomic dysfunction is orthostatic hypotension. Symptoms include generalized weakness, light-headiness, mental "clouding" up to syncope. Factors like heat, food, alcohol, exercise, activities which increase intrathoraric pressure (e.g. defecation, coughing) and certain drugs (e.g. vasodilators) can worsen a probably asymptomatic orthostatic hypotension. Non-medical and medical therapies can help the patient to cope with a disabling symptomatic orthostatic hypotension. Supine hypertension is often associated with orthostatic hypotension. The prognostic role of cardiovagal and baroreflex dysfunction is still not yet known.

Abstract
OBJECTIVE To measure the frequency of and direct costs related to parkinsonian syndromes associated with orthostatic hypotension (OH). PATIENTS/METHODS Patients over 45 years using at least one antiparkinsonian drug (excluding piribedil or anticholinergics prescribed alone) were identified from the Haute-Garonne Social Security prescription database and separated in two groups according to simultaneous prescription (OH group) or not (control group) of drugs for orthostatic hypotension. Direct medical costs were analysed retrospectively, over a 6-month period, from the health care payer's perspective. RESULTS Eighty-eight patients (9.1%) out of 971 parkinsonian also received antihypotensive drugs. Direct medical costs were significantly higher in OH than in control group (4.425 vs. 3.074 Euro/patient/6 months, p < 0.05). Beside hospitalisation and ancillary cares, drugs accounted for highest expenses (989 vs. 781 Euro/patient/6 months in control group) since use of controlled-release levodopa formulations or dopamine agonists was higher in OH group. CONCLUSION Occurrence of OH is associated with higher medical expenditure in parkinsonian syndromes.

Abstract
The benefit of levodopa and carbidopa therapy in improving visual function in patients with non-arteritic anterior ischaemic neuropathy (NAION) was evaluated. Twenty-four subjects with NAION were randomly selected to receive either levodopa-carbidopa or a placebo. Visual functions of neither the study nor the placebo groups showed improvement. Side effects of levodopa such as dizziness, orthostatic hypotension, vomiting and cardiac arrhythmia were seen. Levodopa and carbidopa had no therapeutic effect on visual recovery in our patients with NAION.

Abstract
OBJECTIVE To clarify the characteristics of sympathetic vasomotor function in Parkinson's disease by sympathetic neurographic analysis. METHODS Muscle sympathetic nerve activity (MSNA) was recorded using a microneurographic technique at rest and during head up tilt in 18 patients with idiopathic Parkinson's disease and 21 healthy controls. RESULTS Heart rate and blood pressure at rest did not differ between index and control subjects. The increase in these variables and MSNA in response to tilting was slightly blunted in the Parkinson's group. Resting MSNA showed a negative correlation with age in patients with Parkinson's disease (p<0.05) and a positive correlation with age in controls (p<0.01). There was a negative correlation between duration of disease or disability levels and MSNA (p<0.01). CONCLUSIONS Sympathetic vasomotor function may be related to age and disease duration in Parkinson's disease.

Abstract
Autonomic nervous system (ANS) dysfunction is common in Parkinson's disease (PD), affects 70% to 80% of patients, and causes significant morbidity and discomfort. Autonomic nervous system dysfunction symptoms in PD include sexual dysfunction, swallowing and gastrointestinal disorders, bowel and bladder abnormalities, sleep disturbances, and derangements of cardiovascular regulation, particularly, orthostatic hypotension. Autonomic nervous system dysfunction in PD may be caused by an underlying degenerative process that affects the autonomic ganglia, brainstem nuclei, and hypothalamic nuclei. Anti-parkinsonian medications can cause or worsen symptoms of ANS dysfunction. The care of a PD patient with ANS dysfunction relies on its recognition and directed treatment, including coordinated care between the neurologist and appropriate subspecialist. Pharmacotherapy may be useful to treat orthostasis, gastrointestinal, urinary, and sexual dysfunction.

Abstract
Less than a consensus exists as to whether chronic treatment with selegiline in combination with levodopa/carbidopa in patients with Parkinson's disease, is associated with more pronounced orthostatic hypotension than treatment with levodopa/carbidopa alone. To resolve this issue, we compared orthostatic tolerance and autonomic reflexes in 95 patients with Parkinson's disease treated chronically with either selegiline alone (n = 10), levodopa/carbidopa alone (n = 49) or both agents combined (n = 36). Supine heart rate and blood pressure, autonomic cardiovascular reflexes and the frequency and magnitude of orthostatic hypotension were similar in all three treatment groups.

Abstract
Orthostatic hypotension is common in elderly patients, and is now considered to be an important prognostic factor for cognitive decline and mortality. In patients with Parkinson's disease, the prevalence of symptomatic orthostatic hypotension may be as high as 20%. Two factors could explain this high prevalence. First, dopaminergic drugs may induce or worsen orthostatic hypotension. Secondly, Parkinson's disease is a cause of primary autonomic failure with an involvement of the peripheral autonomic system as shown by the ubiquitous distribution of Lewy bodies and reduced iobenguane [metaiodobenzylguanidine (MIBG)] cardiac uptake. These pathological and pharmacological characteristics clearly differentiate autonomic failure of Parkinson's disease from multiple system atrophy. If autonomic abnormalities appear to be present from the first stage of the disease, early onset (within the first year) of symptomatic orthostatic hypotension in the course of parkinsonism can be considered as an exclusion criteria for idiopathic Parkinson's disease. No specific clinical trials have evaluated the effects of antihypotensive drugs in patients with Parkinson's disease and thus no specific therapeutic strategy can be recommended. The management of orthostatic hypotension in patients with Parkinson's disease should always start with patient education and nonpharmacological treatment. Drug therapy should be reserved for symptomatic patients who do not get benefit from nonpharmacological management. Among the available drugs, alpha1-adrenergic agonists (mainly midodrine) or plasma volume expanders (mainly fludrocortisone) are the most frequently used. There are also some drugs that are currently investigational such as yohimbine and droxidopa. Other drugs such as desmopressin or octreotide may be of interest in some situations. Domperidone is widely used in patients with parkinsonism with no proven effect on orthostatic hypotension.

Abstract
Both the catechol-O-methyltransferase (COMT) inhibitor entacapone and the monoamine oxidase B (MAO-B) inhibitor selegiline are L-dopa extenders. Both are used, often simultaneously, as adjuncts to L-dopa/dopa decarboxylase (DDC) inhibitor treatment of Parkinson's disease (PD). Their possible interactions have not been previously studied in a double-blind manner.We studied clinical response, tolerability, haemodynamics and cardiac rhythm in 16 PD patients with end-of-dose-type motor fluctuations. The patients' individual L-dopa/DDC inhibitor treatment was stabilized before the experimental treatments. This was followed by three consecutive, randomized, double-blind 2-week treatment periods with entacapone (200mg with each L-dopa dose), selegiline (10mg o.d.) or both entacapone and selegiline with the L-dopa/DDC inhibitor medication. Clinical efficacy (L-dopa test with repeated motor and dyskinesia scoring) and safety (orthostatic test, 24-h ambulatory ECG, haematological and clinical chemistry variables and adverse events) evaluations were performed before each treatment (control) and at the end of each treatment period.All three treatments, entacapone, selegiline, and entacapone+selegiline as adjunct to L-dopa/DDC inhibitor improved (p<0.05) clinical disability compared to L-dopa only but they did not differ significantly from each other. Dyskinesias increased with all the treatments, statistically significantly (p<0.01) with entacapone+selegiline. No significant differences in haemodynamics were observed between control and any of the experimental treatments, or between the experimental treatments in the orthostatic test. One patient already had symptomatic orthostatism before experimental treatments (control). In two other patients orthostatism emerged after the introduction of selegiline, and in one after every experimental treatment. Twenty-four-hour ECG did not show any differences in supraventricular or ventricular extrasystoles or heart rate between treatments. No statistically significant differences were observed in adverse events or in haematology and clinical chemistry variables. One patient treated with entacapone+selegiline discontinued the study due to dizziness and insomnia. Our results suggest that co-administration of entacapone with L-dopa/DDC inhibitor, with or without selegiline, improves clinical disability, is safe, but may also enhance dopamine-related adverse events to some extent in PD patients with end-of-dose type motor fluctuations.

Abstract
OBJECTIVES To clarify the autonomic dysfunction in idiopathic Parkinson's disease (PD) and vascular parkinsonism (VP), we investigated the relationship between blood pressure (BP) and pulse rate (PR), the standing test, and the coefficient of variation in the R-R interval (CV[R-R]). MATERIALS AND METHODS BP and PR were determined automatically every 30 min for 24 h in 15 PD patients, 15 VP patients and 15 healthy volunteers. The CV(R-R) values evaluated by an electrocardiogram and the standing test were also performed. RESULTS The BP-PR relationship was lost in the patient groups. There was no significant difference in the standing test between the control and patient groups. A significantly decreased CV(R-R) was observed in the VP group. CONCLUSION We speculate that our results may reflect an imbalance between the sympathetic and parasympathetic nervous systems in PD and VP.

Abstract
OBJECTIVES To investigate the prevalence of orthostatic hypotension and the nature of the postural events related to a fall in blood pressure in patients with Parkinson's disease. METHODS Blood pressure was measured first in a supine position after a rest of at least 15 minutes and every minute during 10 minutes of an active standing up procedure. Orthostatic hypotension was considered as present when a fall of at least 20 mm Hg of systolic blood pressure was recorded. Postural events which occurred during the standing test were identified from a questionnaire and self reporting. Statistical analysis was performed to determine the relation between orthostatic hypotension and disease characteristics (duration, severity) and the use of antiparkinsonian drugs. Ninety one consecutive patients with Parkinson's disease (48 women, 43 men, mean age 66 (SD 9) years) participated to the study. RESULTS A fall of at least 20 mm Hg of systolic blood pressure was found in 58.2% of the patients. Orthostatic hypotension was asymptomatic in 38.5% and associated with postural events in 19.8% of the patients. Symptomatic (but not asymptomatic) orthostatic hypotension was related to duration and severity of the disease and with the use of higher daily levodopa and bromocriptine doses. The analysis of the relation between the postural symptoms (and the need for standing test abortion) with the fall in systolic blood pressure allowed the identification of six clinical criteria specific of orthostatic hypotension. A direct relation between the postural changes in systolic blood pressure and the number of clinical events in this clinical scale was found. CONCLUSION The frequency of orthostatic hypotension in Parkinson's disease is high and it is possible to establish a clinical rating scale which could be used to assess the effects of drugs employed in the management of orthostatic hypotension.

Abstract
Centrally and locally elicited sympathetic vasoconstrictor responses were examined in 12 patients with symptoms and signs of cardiovascular autonomic dysfunction due to Parkinson's disease. The sympathetic reflex mechanisms were measured in skeletal muscle and subcutaneous tissue of the arm and leg using the 133-Xenon washout technique. This method allows differentiation between local and central sympathetic reflexes in different tissues. The results indicate an abolished centrally mediated vasoconstrictor response in skeletal muscle in the arm and a decreased response in skeletal muscle in the leg and in subcutaneous tissue. This is in agreement with an autonomic dysfunction located in the central nervous system. A possible spinal sympathetic reflex controlling blood flow in subcutaneous tissue and leg muscles is considered. The sympathetic vasoconstrictor responses in parkinsonian patients without autonomic failure were of normal magnitude and the responses were not affected by long-term levodopa treatment.

Abstract
The influence of the type, duration, severity and levodopa treatment of Parkinson's disease on autonomic involvement has been assessed. The Valsalva manoeuvre, deep breathing, handgrip and orthostatic tests were performed in 50 patients with Parkinson's disease and in a control group of 30 healthy subjects. No attempt was made to classify further patients with parkinsonian features into groups such as the Shy-Drager syndrome or multiple system atrophy. All test results were significantly smaller in patients than in healthy subjects. The diastolic pressure increase during handgrip was significantly smaller in akinetic-rigid than in tremor-akinetic-rigid type patients. The Valsalva ratio and orthostatic test results were significantly smaller in patients with longer duration than in those with shorter duration of disease. All test results except those of the orthostatic test were significantly smaller in patients with the more severe form than in those with the less severe form of disease. Comparing test results of levodopa-treated and -untreated patients no significant differences were found. Our studies in parkinsonian patients suggest that (1) sympathetic impairment is more pronounced in akinetic-rigid than in tremor-akinetic-rigid type patients; (2) sympathetic impairment occurs early, whereas parasympathetic impairment develops later; (3) sympathetic and parasympathetic impairment parallels the severity of disease; (4) orthostatic parameters are more duration-sensitive than severity-sensitive; (5) chronic levodopa treatment does not markedly influence cardiovascular autonomic responses.

Abstract
We have investigated the autonomic function of 95 patients with Parkinson disease (PD) by testing their cardiovascular reflexes and compared the results with those of 53 healthy volunteers. 51.1% of the patients were on antiparkinsonian therapy. The patients showed a smaller heart rate response to deep breathing with a mean exhalation-inspiration difference of 87.73 +/- 7 (p: 0.0005), a smaller heart rate response to standing with a mean 30: 15 index of 1.18 +/- 0.25 (p: 0.01), and a smaller blood pressure rise to handgrip with a mean rise of 9.53 +/- 8.76 mmHg (p: 0.005). We found a higher percentage of patients with established sympathetic lesion (41% vs 34%) or atypical patterns of global autonomic function involvement (33% vs 26%), but the percentage of subjects with parasympathetic lesion was similar in both, patients and controls (16% vs 15%). We found no significant difference on cardiovascular performance between treated and untreated patients. The patients with autonomic impairment were older than the patients with normal autonomic function. Our findings suggest that patients with PD have a true autonomic dysfunction.

Abstract
We investigated autonomic function in patients with idiopathic Parkinson's disease (PD) by measuring sympathetic skin response (SSR) and R-R interval variation (RRIV). Sixty-two PD patients and 62 age-matched normal subjects were recruited. Abnormal SSR was noted in nine (14.5%) PD patients, including three in Stage II, three in Stage III, and three in Stage IV, but not in Stage I patients or normal subjects. Four of these nine patients had postural hypotension. Abnormal SSR was correlated with duration of illness and impotence. In PD patients, abnormal SSR may be due to intermediolateral column dysfunction. After logarithmic transformation and age adjustment, 19 (31.6%) of 60 PD patients had abnormal RRIV during rest and deep breathing. Abnormal RRIV was not related to staging or duration of illness. Patients with constipation had significantly lower RRIV, indicating parasympathetic dysfunction. RRIV was not affected by acute or chronic L-dopa treatment. The agreement between RRIV and SSR in PD patients was poor (kappa = -0.07). It appears that abnormal SSR, but not RRIV, may be associated with more autonomic disturbances in PD patients.
