Abstract
While early-onset Parkinson's disease (EOPD) caused by mutations in the parkin gene (PRKN) tends to have a relatively benign course compared to genetically undetermined (GU)-EOPD, the exact underlying mechanisms remain elusive. We aimed to search for the differences between PRKN-EOPD and GU-EOPD by dopamine transporter (DAT) and glucose metabolism positron-emission-tomography (PET) imaging. Twelve patients with PRKN-EOPD and 16 with GU-EOPD who accepted both 11C-2b-carbomethoxy-3b-(4-trimethylstannylphenyl) tropane (11C-CFT) and 18F-fluorodeoxyglucose PET were enrolled. The 11C-CFT uptake was analyzed on both regional and voxel levels, whereas glucose metabolism was assessed in a voxel-wise fashion. Correlations between DAT and glucose metabolism imaging, DAT imaging and clinical severity, as well as glucose metabolism imaging and clinical severity were explored. Both clinical symptoms and DAT-binding patterns in the posterior putamen were highly symmetrical in patients with PRKN-EOPD, and dopaminergic dysfunction in the ipsilateral putamen was severer in patients with PRKN-EOPD than GU-EOPD. Meanwhile, the DAT binding was associated with the severity of motor dysfunction in patients with GU-EOPD only. Patients with PRKN-EOPD showed increased glucose metabolism in the contralateral medial frontal gyrus (supplementary motor area (SMA)), contralateral substantia nigra, contralateral thalamus, and contralateral cerebellum. Notably, glucose metabolic activity in the contralateral medial frontal gyrus was inversely associated with regional DAT binding in the bilateral putamen. Patients with PRKN-EOPD showed enhanced metabolic connectivity within the bilateral putamen, ipsilateral paracentral and precentral lobules, and the ipsilateral SMA. Collectively, compared to GU-EOPD, PRKN-EOPD is characterized by symmetrical, more severe dopaminergic dysfunction and relative increased glucose metabolism. Meanwhile, SMA with elevated glucose metabolism and enhanced connectivity may act as compensatory mechanisms in PRKN-EOPD.

Abstract
GBA variants are associated with increased risk and earlier onset of Parkinson's disease (PD), and more rapid disease progression especially with "severe" variants typified by p.L483P. GBA mutation screening studies from South-East Asia, with > 650 million inhabitants of diverse ancestries, are very limited. We investigated the spectrum of GBA variants, and associated clinico-demographic features, in a multi-ethnic PD cohort in Malaysia. Patients (n = 496) were recruited from seven centres, primarily of Chinese (45%), Malay (37%), and Indian (13%) ethnicities. All GBA coding exons were screened using a next-generation sequencing-based PD gene panel and verified with Sanger sequencing. We identified 14 heterozygous GBA alleles consisting of altogether 17 missense variants (8 classified as pathogenic or likely pathogenic for PD) in 25 (5.0%) patients, with a substantially higher yield among early (< 50 years) vs. late-onset patients across all three ethnicities (9.1-13.2% vs. 1.0-3.2%). The most common variant was p.L483P (including RecNciI, n = 11, 2.2%), detected in all three ethnicities. Three novel variants/recombinant alleles of uncertain significance were found; p.P71L, p.L411P, and p.L15S(;)S16G(;)I20V. The common European risk variants, p.E365K, p.T408M, and p.N409S, were not detected. A severe disease course was noted in the majority of GBA-variant carriers, across a range of detected variants. We report a potentially novel observation of spine posture abnormalities in GBA-variant carriers. This represents the largest study on GBA variation from South-East Asia, and highlights that these populations, especially those with EOPD, would be relevant for studies including clinical trials targeting GBA pathways.

Abstract
Axial deformities such as camptocormia or Pisa syndrome in people with Parkinson's disease (PwP) are poorly understood. The scarcity of information may result from the shortage of reliable and responsive evaluation instruments. We evaluated the body height loss (BHL) as a new measure for PwP with axial deformities. 50 PwP with axial deformity defined by an UPDRS item 28 value of at least 2 were included in this mono-center study. We measured body height while lying supine and after 1 min of standing, providing a percentage value of BHL, and compared this measure to other clinical variables. BHL depended on the Hoehn and Yahr clinical stage and correlated with clinical scales for function and mobility, but not with timely measures of the axial disorder such as age at diagnosis or duration of disease. ANOVA showed that only lumbar flexion explained the variability of BHL (F = 21.0, p < 0.0001), but not kyphosis (F = 0.4, p = 0.74) or lateroflexion (F = 0.6, p = 0.6). Re-test reliability of BHL was good with к = 0.76 (p < 0.0001). BHL resulted from the lumbar spine and the hip joint and not from the thoracic spine or lateroflexion. This observation conforms to the concept of upper-type and lower-type camptocormia with only the latter leading to a BHL. The assessment of the BHL is shown to be a well defined, easy to perform, and reliable measure for the clinical evaluation of lower-type camptocormia.

Abstract
OBJECTIVE The aim of this work was to identify factors predictive of postoperative improvement of camptocormia in patients with Parkinson's disease (PD) treated by subthalamic nucleus (STN) stimulation. BACKGROUND Camptocormia, one of the most disabling features of PD, often responds poorly to medical therapies. The reported effects of deep brain stimulation on PD-associated camptocormia vary, and preoperative characteristics affecting the surgical outcome remain unclear. METHODS We evaluated 17 patients with camptocormia whose preoperative off-medication thoracolumbar angle exceeded 45°. We used photographs to measure their thoracolumbar angle preoperatively, 3 months after surgery, and at the last follow-up (mean 36.5 months postoperatively) in status on-medication and off-medication. The patient age, duration of PD and camptocormia, daily medications, Unified Parkinson's Disease Rating Scale (UPDRS) subscores and the Schwab-England activity of daily living scale (S-E) were also recorded. Univariate analysis was performed to identify factors predictive of the postoperative improvement of camptocormia. RESULTS STN stimulation significantly improved the UPDRS subscores and S-E, and resulted in a reduction of daily medications 3 months post-treatment. The preoperative thoracolumbar angle (mean±SD) in status off-medication (84.0±29.5°) was significantly ameliorated 3 months postoperatively (49.8±29.3°) and at the last follow-up (54.8±28.3°). There was no correlation between the postoperative camptocormia improvement rate and preoperative parameters other than the duration and severity of camptocormia and the levodopa responsiveness of the thoracolumbar angle. Symptom duration negatively affected levodopa responsiveness. CONCLUSIONS STN stimulation improves PD-associated camptocormia in parallel with preoperative levodopa responsiveness. Long symptom duration interferes with levodopa responsiveness.

Abstract
To investigate the frequency and clinical characteristics of camptocormia in Chinese PD patients, we included 705 patients with PD and studied the clinical features and prevalence of camptocormia. Forty-six (6.5%) patients presented with camptocormia at the time of evaluation. The mean disease duration of PD patients with camptocormia was significantly longer than that without camptocormia (P < 0.01). After adjusted for age and disease duration, compared with patients without camptocormia, PD patients with camptocormia presented with higher score of UPDRS part III (P < 0.01), higher H&Y stage (P < 0.01), higher score of Non-Motor Symptoms Scale (P < 0.01) and lower score of Mini-Mental Status Examination (P < 0.01). Binary logistic regression models indicated that camptocormia is associated with higher H&Y stage and UPDRS part III score. Camptocormia is not rare (6.5%) with the disease progression of PD in Chinese PD population and is associated with more advanced PD.

Abstract
BACKGROUND AND IMPORTANCE Camptocormia is characterized by abnormal flexion of the thoracolumbar spine that increases during upright posture and abates in the recumbent position and has been reported to occur in patients with Parkinson disease. Camptocormia causes significant spinal and abdominal pain, impairment of balance, and social stigma. CLINICAL PRESENTATION A 57-year-old woman with Parkinson disease developed severe camptocormia, which did not improve with trials of antiparkinsonian and muscle relaxant medications. The patient was successfully treated with bilateral globus pallidus interna deep brain stimulation surgery under general anesthesia. High-frequency neuromodulation afforded relief of camptocormia and improvement in Parkinson disease symptoms. CONCLUSION Camptocormia in Parkinson disease may represent a form of dystonia and can be treated effectively with chronic pallidal neuromodulation.

Abstract
BACKGROUND We describe the four decades follow-up of 14 parkin patients belonging to two large eight-generation-long in-bred Muslim-Arab kindreds. RESULTS All patients had a single base-pair of adenine deletion at nucleotide 202 of exon 2 (202A) of the parkin gene (all homozygous, one heterozygous). Parkinson's disease onset age was 17-68 years. Special features were intractable axial symptoms (low back pain, scoliosis, camptocormia, antecollis), postural tremor, and preserved cognition. CONCLUSIONS The 202A deletion of the parkin gene causes early-onset Parkinson's disease with marked levodopa/STN-DBS-resistant axial features. Postural tremor and preserved cognition, even after 40 years of disease, were also evident.

Abstract
Extreme forward flexion of the spine, named camptocormia (CC), and head drop syndrome (HD) may be among the most disabling symptoms in Parkinson's disease (PD). This study aims to eludicate the etiology of PD-associated CC and HD via a multidisciplinary approach (clinical examination, electromyography, MRI, genetic analysis, muscle morphology) centering on the histology of the paraspinal muscles. We studied 17 patients with the clinical diagnosis of PD and CC or head drop syndrome and six controls. We performed muscle biopsies of paraspinal muscles and deep neck extensor muscles. Mean age at onset of postural abnormality was 66 years and mean latency between onset of parkinsonian symptoms to first signs of CC or head drop was 7 years. The electromyogram of paraspinal muscles was abnormal in 13-14 patients. Histopathology revealed chronic myopathic changes in 14 of 17 biopsies, consisting of abnormal variation in fiber size, increase in internal nuclei, and increase in connective tissue, myofibrillar disarray and similarities to protein surplus myopathies. Interestingly, heterozygous variants in the Parkin gene were found in 2 of 9 investigated patients. We conclude that CC and HD in PD are predominantly myopathic. Aberrant protein aggregation may link PD and CC.

Abstract
The authors report on 2 young patients who developed drug-resistant idiopathic dystonic camptocormia (bent spine) and were treated successfully by deep brain stimulation (DBS) of the globus pallidus internus (GPi). The first patient, a 26-year-old woman, suffered for 3 years from such severe camptocormia that she became unable to walk and was confined to bed or a wheelchair. The second patient, a 21-year-old man, suffered for 6 months from less severe camptocormia; he was able to walk but only for short distances with a very bent spine, the arms in a parallel position to the legs, and the hands almost approaching the floor to potentially support him in case of a forward fall. Within a few days following DBS, both patients experienced marked clinical improvement. At most recent follow-up (44 months in one case and 42 in the other), the patients' ability to walk upright remained normal. Similar findings have only been reported recently in a few cases of camptocormia secondary to Parkinson disease or tardive dyskinesia. On the basis of the experience of these 2 idiopathic cases and the previously reported cases of secondary camptocormia with a favorable response to GPi DBS, the authors postulate that specific patterns of oscillatory activity in the GPi are vital for the maintenance of erect posture and the adoption of bipedal walking by humans.

Abstract
Camptocormia is characterized by an excessive anterior flexion of the spine that appears only when standing or walking. The origin of this symptom remains unknown, but recent clinical reports of camptocormia associated with Parkinson's disease (PD) suggest cerebral involvement in the pathogenesis of camptocormia. This study was undertaken to investigate the hypothesis that camptocormia in PD has a central origin. Seventeen PD patients with camptocormia were prospectively enrolled and were compared to 10 matched PD patients without camptocormia and 12 normal controls. The normalized volumes of the brain, striatal nuclei, and the cross-sectional areas of the midbrain and pons were measured on three-dimensional magnetic resonance imaging. Data were correlated with the severity of the symptoms. The normalized axial surface of the midbrain was statistically smaller in PD patients with camptocormia than in normal controls (P = 0.01). The normalized volumetric data were not statistically different in PD patients with camptocormia. There was a significant negative correlation between the severity of camptocormia and the normalized brain volume (P < 0.009; R = -0.649) and sagittal pons area (P < 0.01; R = -0.642). The results suggest that PD with camptocormia may represent a selective form of PD in which a specific neuronal dysfunction possibly occurs within the brainstem.

Abstract
BACKGROUND Camptocormia, characterised by extreme forward flexion of the thoracolumbar spine and severe stooping in the supine position, seems to be prevalent in Parkinson's disease. OBJECTIVE The aim of this study was to identify features of parkinsonian camptocormia and to describe the main clinical characteristics of patients with Parkinson's disease who develop the condition. METHODS An extensive range of clinical, biochemical and imaging data were gathered for 23 patients with Parkinson's disease with camptocormia, notably including magnetic resonance imaging (MRI) of the brain and spine, electromyographic recordings of the paravertebral muscles and muscle biopsies. RESULTS Camptocormia occurred in severe Parkinson's disease with axial predominance, motor fluctuations and dysautonomic symptoms. The condition was often associated with spondyloarthritic changes and pain. MRI showed paraspinal muscle signal abnormalities in five patients and fatty involution in seven patients. The seven patients had motor unit reductions on the spinal erector electromyogram. The MRI results for the girdle muscles were normal. Cranial MRI showed signal abnormalities for the basal ganglia in three patients. DISCUSSION Various mechanisms may contribute to the development of parkinsonian camptocormia: dopaminergic depletion in Parkinson's disease induces functional changes in the organisation of the corticospinal and reticulospinal tracts, where dysfunction could contribute to axial rigidity. Furthermore, rigidity of the spinal flexion muscles could lead to under-use of the spinal extension muscles, which become progressively atrophic. Rigidity may also induce spinal deformations, leading to a neurogenic syndrome via compression of the spinal nerves. CONCLUSION The screening and early management of camptocormia in Parkinson's disease is likely to be important for preventing axial disorders and spinal deformations.

Abstract
BACKGROUND Camptocormia is defined as an abnormal flexion of the trunk that appears when standing or walking and disappears in the supine position. The origin of the disorder is unknown, but it is usually attributed either to a primary or a secondary paravertebral muscle myopathy or a motor neurone disorder. Camptocormia is also observed in a minority of patients with parkinsonism. OBJECTIVE To characterise the clinical and electrophysiological features of camptocormia and parkinsonian symptoms in patients with Parkinson's disease and camptocormia compared with patients with Parkinson's disease without camptocormia. METHODS Patients with parkinsonism and camptocormia (excluding patients with multiple system atrophy) prospectively underwent a multidisciplinary clinical (neurological, neuropsychological, psychological, rheumatological) and neurophysiological (electromyogram, ocular movement recording) examination and were compared with age-matched patients with Parkinson's disease without camptocormia. RESULTS The camptocormia developed after 8.5 (SD 5.3) years of parkinsonism, responded poorly to levodopa treatment (20%) and displayed features consistent with axial dystonia. Patients with camptocormia were characterised by prominent levodopa-unresponsive axial symptoms (ie, axial rigidity, gait disorder and postural instability), along with a tendency for greater error in the antisaccade paradigm. CONCLUSION We suggest that (1) the salient features of parkinsonism observed in patients with camptocormia are likely to represent a specific form of Parkinson's disease and camptocormia is an axial dystonia and (2) both camptocormia and parkinsonism in these patients might result from additional, non-dopaminergic neuronal dysfunction in the basal ganglia.

Abstract
The motor symptoms of Parkinson's disease are predominantly due to progressive degeneration of nigral dopaminergic neurons. In most cases there is a substantial asymmetry of clinical symptoms from disease onset, which occurs in sporadic and in hereditary forms of the disease. However, the mechanism of such unilaterality of symptom appearance is not understood. There is only sparse information about whether symptom-side predominance is genetically coded and determined years before symptom onset, or whether it is acquired and related to side differences in vulnerability of the degenerating neurons. In this Personal View we review data for unilaterality of symptoms at different disease stages. We also discuss several pathological, genetic, environmental, and toxic possibilities for explaining the mechanism of side predominance.

Abstract
Camptocormia is characterised as an extreme bent-forward posture of the trunk that disappears in the recumbent position. On X-ray, trunk flexion appears without vertebral rotation as in scoliosis. The condition is a well-known complication of Parkinson's disease (PD) at the late stage. The authors present the case of a 77-year-old woman affected by severe camptocormia, which appeared and worsened in less than 6 months and hindered gait. Despite no signs of PD, neuro-imaging (DAT-Scan) showed an L-Dopa transducer decrease in putamens. A few weeks later, bradykinesia appeared and the clinical diagnosis of PD became more obvious. L-Dopa improved bradykinesia but did not change the bent-spine posture. A 1-year follow-up showed no other signs of PD other than bradykinesia, but the camptocormia was unchanged.

Abstract
Camptocormia is a well-known feature in cases of Parkinson disease (PD), and is usually unresponsive to dopaminergic therapy. A 62-year old man with a long history of PD and severe progressive camptocormia underwent bilateral pallidal stimulation. During the next 6 months a sustained improvement in trunk flexion was observed. After 14 months of follow up, the patient's trunk flexion is almost normal.

Abstract
INTRODUCTION The camptocormia (bent spine) is characterized by a severe forward flexion of the thoracolumbar spine which disappears in the supine position. Clinical case. We describe a typical case observed in a parkinsonian patient. The MRI, electromyogram and biopsy of the paraspinal muscles revealed a typical myositis pattern. DISCUSSION This case, the sixth published to our knowledge, confirms that focal myositis is associated with the camptocormia in Parkinson's disease. Typically it is observed in male subjects, appearing 4 to 6 years after the onset of Parkinson's disease, in fluctuating patients treated by an association of L-Dopa and agonist. It appears quickly and becomes the most important symptom. Antiparkinsonian drugs are useless. CONCLUSION This exceptional picture raises original pathophysiological and therapeutic questions. Systematic studies should be performed in order to detail the pathophysiological link between these 3 entities: Parkinson's disease, focal myositis and camptocormia.

Abstract
Although a mild stooped posture is a hallmark of parkinsonism, extreme trunk forward flexion is not common. This phenomenon was described in different etiological entities and called camptocormia. Other similar presentations called Pisa syndrome and antecollis were described mainly in extrapyramidal disorders. Authors present two cases of probable multiple system atrophy (MSA) with predominant parkinsonism and Pisa syndrome (or camptocormia). Both of them were previously misdiagnosed as idiopathic Parkinson's disease (PD) and one was reported 1 year earlier. The typical clinical presentation fulfilling the diagnostic criteria for multiple system atrophy, rapid progression with lack of responsiveness to L-DOPA and apomorphine and typical MRI putaminal pathology observed in both cases allowed us to make a diagnosis. Accuracy of clinical diagnosis in multiple system atrophy is still very poor. Therefore, unusual or rare clinical presentations may support the final diagnosis. The camptocormia, Pisa syndrome and antecollis may represent the continuum of the same motor phenomenon and most of the authors refer them to unusual form of axial dystonia. According to many clinical presentations on different forms of camptocormia/Pisa syndrome authors conclude that not etiology, but the localization of specific lesion, probably within putamen is responsible for that form of dystonia. In cases of parkinsonism and severe forward flexion of trunk multiple system atrophy, diagnosis should be considered.
