Despite recent advances in tremor and dystonia classification, it remains difficult to discriminate essential tremor from dystonic tremor as they are similar in appearance and no biomarker exists. Fur...
Symptoms of functional neurological disorder tend to be variable, yet patients often report them being present constantly and of permanently severe intensity. Furthermore, they typically worsen when t...
To test the notion of inaccurate symptom perception or reporting, we directly compared subjective to objective tremulousness of reaching movements in people with a functional action tremor, people wit...
There was no significant difference in subjective compared to objective tremor severity between the three groups for either the real-time or retrospective conditions....
People with functional tremor do not perceive or report their tremor in an exaggerated manner, compared to people with an organic tremor or healthy controls. We propose that symptom exacerbation throu...
Essential tremor (ET) is characterized by action tremor, although rest tremor may also occur. Despite this, rest tremor has not been studied extensively. A dearth of studies compare the relationship o...
Two-hundred-and-thirteen ET cases underwent detailed neurological examination, including evaluations of rest, simple kinetic, postural, and intention tremors. A movement disorders neurologist assessed...
Sixty-two cases (29.2%) had rest tremor while seated. Fifteen (7.4%) had rest tremor while standing. Among asymmetric tremor pairings, concordant pairings occurred 2-2.7 times more frequently than dis...
Rest tremor often lateralized with other tremor types. These data add to our knowledge of the phenotypic manifestations of ET....
Since the initial description of Essential Tremor (ET), the entity of ET with rest tremor has proven to be a controversial concept. Some authors argued it could be a late manifestation of ET, others s...
Patients often exhibit very severe or disabling forms of tremor that cannot be clearly characterized....
To present a series of 37 cases of tremor considered...
Relevant demographic and clinical information were collected. The following tools were applied: the Mini-Mental State Examination (MMSE); the Hospital Anxiety and Depression Scale (HADS); the Fahn-Tol...
The cases presented higher scores on the anxiety and depression subscales of the HADS than the controls (...
There are patients with unclassifiable and extremely disabling tremors who respond poorly to the pharmacological therapy options....
Tremor is a commonly encountered condition in the primary care setting and can manifest at rest, with action, or both. Common causes include Parkinson disease, essential tremor, and drug-induced tremo...
The approach and diagnosis of patients with tremor may be challenging for clinicians. According to the most recent consensus statement by the Task Force on Tremor of the International Parkinson Moveme...
There is some debate on the relationship between essential tremor with rest tremor (rET) and the classic ET syndrome, and only few MRI studies compared ET and rET patients. This study aimed to explore...
Thirty-three ET patients, 30 rET patients and 45 control subjects (HC) were enrolled. Several MR morphometric variables (thickness, surface area, volume, roughness, mean curvature) of brain cortical r...
rET patients showed increased roughness and mean curvature in some fronto-temporal areas compared with HC and ET, and these metrics significantly correlated with cognitive scores. Cortical volume in t...
Our study demonstrated higher cortical involvement in fronto-temporal areas in rET than in ET patients, which may be linked to the cognitive status. A machine learning approach based on MR volumetric ...
The tremor characteristics of patients with spinocerebellar ataxia 12 (SCA12) are often likened to those in patients with essential tremor (ET); however, data are sparse, and videotaped tremor examina...
A 37-year-old woman with progressive hand and head tremors underwent genetic testing after conventional diagnostics failed to explain her symptoms. A...
Although often likened to ET, under careful scrutiny, the tremor characteristics observed in this patient with SCA12 were inconsistent with those typically seen in ET. Such discrepancies highlight the...
This report characterizes in detail an early-stage SCA12 patient initially misdiagnosed as essential tremor, underscoring the importance of nuanced clinical assessment and genetic testing in atypical ...
Essential tremor (ET) is a highly prevalent movement disorder. As the diagnosis is purely clinical, it is important for clinicians to develop a reliable taxonomy of signs and symptoms of ET. Here, we ...
Two movement disorders neurologists assessed tremor severity from videotaped neurological evaluations of 100 ET cases displaying outstretched and wing posture positions. These raters also completed a ...
Our raters judged tremor observed in the wing posture position to be more severe than tremor observed in the outstretched position (average ratings of 1.17 and 1.03, respectively, p's <0.05). This fin...
Our data reveal that ET cases generally display more severe upper limb tremor in the wing posture position than in the outstretched position. These findings having potential clinical and research impl...
