  BACKGROUND/OBJECTIVE: The fragile X-associated tremor/ataxia syndrome is characterized by intention tremor and ataxia in people who are premutation carriers of the Fragile X gene. [ncbi.nlm.nih.gov]

  Interpretation: Parkinsonian features in FXTAS appear to be characterized as bradykinesia concurrent with cerebellar gait ataxia, postural instability accompanied by intention tremor, and frequent rest tremor, representing distinctive patterns that highlight [ucdavis.pure.elsevier.com]

  The tremor (shaking body parts) of Parkinson disease appears during rest of the limb and disappears or weakens during active movement. Additionally, Parkinson's disease cause walking problems and slow movements. [medical-dictionary.thefreedictionary.com]

  Differential diagnosis Benign essential tremor - far more common; tremor is worse on movement (eg, while trying to hold a cup of tea) and rare while at rest. [patient.info]

• Bradykinesia

  The association between FMR1 mRNA level and bradykinesia implicates pathophysiological mechanisms which may link FMR1 mRNA toxicity, dopamine deficiency and parkinsonism in FXTAS. [ucdavis.pure.elsevier.com]

  Clinical description The disease manifests during the sixth decade of life with parkinsonism, including bradykinesia, axial and limb rigidity, and occasional tremor. [orpha.net]

  Subtle “bradykinesia” has been reported to occur in the “normal elderly” population, but this may reflect a non-specific slowness rather than bradykinesia as defined above. [movementdisorders.org]

  Two intellectually disabled adults with Angelman Syndrome are reported who developed intermittent episodes of a severe resting tremor, cogwheel rigidity and bradykinesia in their late teens. [ncbi.nlm.nih.gov]

• Postural Instability

  However, prior studies have examined parkinsonism (defined as having bradykinesia with at least rest tremor or postural instability) mostly in premutation carriers without a diagnosis of FXTAS. [ucdavis.pure.elsevier.com]

  In the early stage of the disease, eye movements are normal and postural instability is not seen. [orpha.net]

  She had no postural instability or gait abnormality. Physical examination was normal. Liver function and cupric tests were normal. Brain MRI T1-weighted sequences, T2 FLAIR, and T1 with gadolinium injection were also normal. [hindawi.com]

  Postural Instability More pronounced in the later stages, postural instability includes the inability to maintain a steady, upright posture or to prevent a fall. [apdaparkinson.org]

  However, postural instability is not an early PD feature and should alert the clinician of an atypical parkinsonian disorder. [ncbi.nlm.nih.gov]

• Resting Tremor

  Common characteristics include akinesia, expressed as slowness and paucity of movement (eg, decreased arm swing or facial expression) and difficulty in initiating movement, and are associated with rigidity with or without resting tremor. [jamanetwork.com]

  Main features are resting tremor, rigidity and bradykinesia[7]: Tremor at 4-6 Hz is seen at rest and, if not immediately apparent, may be induced by concentration - eg, asking the patient to recite months of the year backwards. [patient.info]

• Akinesia

  Akinesia (Abnormal movement) Probably the most disabling symptom of Parkinson’s is a general lack or slowness of voluntary movements. This is called akinesia and is often seen in association with the rigidity or stiffness of the muscles. [parkinsonswa.org.au]

  In hypo- or akinesia, the patient’s gait is marked by small steps and a stooped torso. The arms swing less, usually on one side. [lecturio.com]

Blood-based NfL might consequently be included in the diagnostic workup of patients with parkinsonian symptoms in both primary care and specialized clinics. [ncbi.nlm.nih.gov]

If the twins remained suspects after the second screening, they were invited to a clinical workup (phase III, see below). [karger.com]

A diagnostic workup for MG was not performed due to a lack of clinical features suggestive of MG, such as fatigability or diurnal fluctuation. Moreover, the short-lasting clinical symptoms observed were not compatible with MG. [e-jmd.org]

Management and treatment There is no treatment curing the disease. Some patients present a moderate response to levodopa that improves bradykinesia and rigidity. [orpha.net]

Treatment Vascular parkinsonism does not respond well to the typical medications used to treat Parkinson's disease. [bcm.edu]

The primary treatment for this type of parkinsonism is weaning off of the offending medication, if possible. [apdaparkinson.org]

What is the prognosis for Wolff-Parkinson-White syndrome? The prognosis for Wolff-Parkinson-White syndrome is excellent. Discussion with your physician can help navigate the treatment options that are available. [medicinenet.com]

Etiology PSP is a 4R tauopathy composed of a preponderance of four-repeat tau isoforms and a characteristic biochemical profile (doublet tau 64 and tau 69). The MAPT H1-clade specific sub-haplotype, H1c, is a risk factor for this disease. [orpha.net]

Upon disturbance of this balance, cells might accumulate and form tumors, leading to cancers of many forms; or, they may die prematurely causing cell death as occurs in the etiology of neurodegenerative diseases. [bits-pilani.ac.in]

Etiology of Parkinson’s Disease Etiology of Idiopathic Parkinson’s Syndrome In most cases, no particular cause can be assigned to idiopathic Parkinson’s disease. [lecturio.com]

Pathophysiological mechanisms underlying Pisa syndrome have not been fully explained. [ncbi.nlm.nih.gov]

Pathophysiology Although the exact cause of MSA evades understanding, many pathophysiologic mechanisms have been uncovered. Iron and ferritin levels appear to be increased in the substantia nigra and striatum. [emedicine.medscape.com]

While the pathophysiology is unclear, decreased dopamine levels and dopamine dysregulation were hypothesized to play a role [30, 34, 35]. [hindawi.com]

Such risk factor modification in essence helps alter the natural course of the disorder, as prevention of further strokes prevents further worsening of already established parkinsonism. [bcm.edu]

Treating underlying conditions, such as stroke or infections, can reduce symptoms or prevent the condition from getting worse. If symptoms make it hard to do everyday activities, the provider may recommend medicine. [medlineplus.gov]

Treatment for atypical Parkinsonism symptoms Because PD medication response is poor in these syndromes, treatment focuses on symptom management – e.g. physical therapy for fall prevention, speech therapy to maximize communication, swallow therapy to prevent [apdaparkinson.org]

This is encouraging news as the need for a reliable, accurate and affordable biomarker is essential in order to make real headway towards a cure or at least a drug regime which could prevent progression (if we could diagnose PD before any damage becomes [eastmidlands-rsn.org]

That’s why it’s unclear how you can prevent the disease. Each year, researchers investigate why Parkinson’s occurs and what can be done to prevent it. [healthline.com]
