463 Possible Causes for Postural Instability

  • Parkinson's Disease

    Greater knowledge of postural control is essential to understand postural instability in PD.[] CONCLUSION: Our results indicate that patients with early PD have subtle signs of postural instability when their attention is diverted or reduced.[] KEYWORDS: Parkinson’s disease; local field potentials; microelectrode recordings; postural instability and gait difficulty; tremor dominant[]

  • Parkinson's Disease Type 3

    instability, a disease that shares symptoms but is different from Parkinson’s disease).[] Drug-induced parkinsonism may be difficult to distinguish from Parkinson’s disease, but the symptoms of tremors and postural instability will generally improve in the weeks[] Parkinson's symptom pattern known as postural instability and gait disturbance (PIGD), which includes "freezing" in mid-step, difficulty initiating movement, shuffling, problems[]

  • Pallidopyramidal Syndrome

    Clinical manifestations include tremor, bradykinesia, rigidity, postural instability, spasticity, mainly in the lower limbs, and hyperreflexia.[] Clinical manifestations include tremor, bradykinesia, rigidity, postural instability, spasticity, mainly in the lower limbs, and hyperreflexia. 2 isoforms of the human protein[]

  • Juvenile Paralysis Agitans of Hunt

    Another disorder in which a resting tremor is one of the main symptoms, accompanied by slowness and poverty of movement, muscular rigidity, and postural instability is Parkinson's[] instability).[] instability or impaired balance and coordination *from Parkinson's Disease Foundation What is Parkinson's Disease?[]

  • Dementia with Lewy Bodies

    Postural instability and bradykinesia is noted on physical exam.[] Supportive clinical features include sensitivity to antipsychotic agents, postural instability and falls, syncope, autonomic dysfunction, delusions and non-visual hallucinations[] instability.[]

  • Machado-Joseph Disease

    Postural instability is often an early feature. We discuss the distinction of this entity from the olivopontocerebellar atrophies.[] Abstract We report a patient presenting at age 16 years with postural instability and falls who developed severe generalized dystonia by the age of 20 years.[] Clinical features include progressive ataxia, DYSARTHRIA, postural instability, nystagmus, eyelid retraction, and facial FASCICULATIONS.[]

  • Progressive Supranuclear Palsy

    Abstract Postural instability and supranuclear gaze palsy represent the key symptoms of Richardson's syndrome, the most frequent clinical manifestation of progressive supranuclear[] The mechanisms underlying backward postural instability in PSP are not understood.[] She had a 3-week history of postural instability and gait disturbance.[]

  • Autosomal Recessive Parkinson Disease 14

    Parkinsonism refers to all clinical states characterized by tremor, muscle rigidity, slowed movement (bradykinesia) and often postural instability.[] Symptoms worsen over time and include resting tremor, muscular rigidity, bradykinesia [abnormal slowness of movement], and postural instability [impaired balance and coordination[] ., Principles of Neurology, 6th ed, p1059, pp1067-75) progressive, degenerative disorder of the nervous system characterized by tremors, rigidity, bradykinesia, postural instability[]

  • Classic Progressive Supranuclear Palsy Syndrome

    PSP-corticobasal syndrome (PSP-CBS) is characterized by progressive, asymmetric dyspraxia, limb rigidity, bradykinesia and progressive postural instability.[] ) No No No Yes (Rest) Early falls Yes No No Sometimes Sometimes No Early postural instability Yes No Yes No Early cognitive decline Often No No No Yes No Early eye movement[] PSP-CBS is characterized by progressive asymmetric dyspraxia, limb rigidity, bradykinesia, and progressive postural instability.[]

  • Motion Sickness

    KEYWORDS: Motion sickness; Postural instability; Virtual reality[] The second theory - the postural instability theory - states that motion sickness comes about not through sensory conflict, but through an inability to control one's posture[] CONCLUSIONS: The results are consistent with the postural instability theory of motion sickness, and help to illuminate relationships between the control of physical and virtual[]
