In this report, we present a family with ataxic GSS that has, however, the same mutation at codon 117 as is present in the telencephalic variant of GSS. [ncbi.nlm.nih.gov]

• Fatigue

  Symptoms Symptoms of prion diseases include: Rapidly developing dementia Difficulty walking and changes in gait Hallucinations Muscle stiffness Confusion Fatigue Difficulty speaking Diagnosis Prion diseases can only be confirmed by taking a sample of [columbianeurology.org]

  They may include: Rapidly developing dementia Difficulty walking and changes in gait Personality changes and impaired memory Depression Muscle stiffness Confusion Fatigue Difficulty speaking Types of prion diseases Creutzfeldt-Jakob Disease has several [ohsu.edu]

  She initially had fatigue and gait instability. She started falling early in the disease course, requiring a walker only 6 months after symptom onset and becoming wheelchair dependent a few months later. [jamanetwork.com]

• Difficulty Walking

  Symptoms include difficulty falling asleep (insomnia), difficulty walking, weight loss and excessive tears in the eye. The symptoms rapidly progress to loss of consciousness and death. [memory.ucsf.edu]

• Surgical Procedure

  IPD may generate infectious prions that might be transmitted by surgical procedures; however, we found no evidence that public health information influenced decisions about predictive testing. [ncbi.nlm.nih.gov]

  In addition, instruments should be kept moist and not allowed to air dry throughout the surgical procedure by immersing them in water or disinfectant solution. [cdc.gov]

• Insomnia

  OBJECTIVE: To establish a variant of sporadic prion disease as the sporadic form of fatal familial insomnia (FFI). [ncbi.nlm.nih.gov]

  Familial prion diseases, which have overlapping signs and symptoms, include familial Creutzfeldt-Jakob disease (CJD), Gerstmann-Sträussler-Scheinker syndrome (GSS), and fatal familial insomnia (FFI). [ghr.nlm.nih.gov]

  Fatal Familial Insomnia (FFI) Fatal familial insomnia (FFI) is a very rare autosomal dominant inherited disease of the brain. [memory.ucsf.edu]

  For instance, the name fatal familial insomnia was originally applied to a family with a genetic disease with insomnia as the first and foremost symptom [ Lugaresi 1986 ]. [prionalliance.org]

• Ataxia

  Two developed symptoms of ataxia, dementia, myoclonus, rigidity, and hemiparesis, and one had a different phenotype with the combination of lower motor neuron deficit, parkinsonism, intellectual decline, and ataxia. [ncbi.nlm.nih.gov]

• Myoclonus

  Two developed symptoms of ataxia, dementia, myoclonus, rigidity, and hemiparesis, and one had a different phenotype with the combination of lower motor neuron deficit, parkinsonism, intellectual decline, and ataxia. [ncbi.nlm.nih.gov]

• Confusion

  The self-propagation of alternative conformations seems to be the common denominator of these "prions," which in future, in order to avoid confusion, may have to be specified either as "neurodegenerative prions" or "infectious prions." © 2013 The Authors [ncbi.nlm.nih.gov]

  Patients may also experience: Involuntary muscle movements Confusion Difficulty walking Mood changes Prion diseases, because they cause spongelike holes in brain tissue, are also called transmissible spongiform encephalopathies. [ohsu.edu]

  Since the naming system can be confusing, we usually avoid it altogether and simply refer to all of these diseases as prion diseases. [prionalliance.org]

• Tremor

  Kuru constitutes a horizontally transmitted prion disease, which after a lengthy incubation period, presents clinically as a progressive cerebellar ataxia associated with tremors. [ncbi.nlm.nih.gov]

  Over the course of the disorder, other features may develop, including tremors, spasticity and rigidity, behavioral changes, confusion, and depression. [invitae.com]

• Gliosis

  Abstract Prion diseases are characterized by accumulation of misfolded protein, gliosis, synaptic dysfunction, and ultimately neuronal loss. This sequence, mirroring key features of Alzheimer disease, is modeled well in ME7 prion disease. [ncbi.nlm.nih.gov]

  Accompanying pathologic changes include gliosis and characteristic histologic vacuolar (spongiform) changes, resulting in dementia and other neurologic deficits. Symptoms and signs develop months to years after the initial exposure to PrP Sc. [msdmanuals.com]

  Neurodegeneration provokes a spongiosis, gliosis and neuronal loss. [alzheimer-europe.org]

  Spongiosis and neuronal atrophy with gliosis of the astrocytes are seen in brain tissue. Kuru plaques are noticeable, being spherical bodies from which filaments radiate. [news-medical.net]

  PrP Sc aggregation is associated with gliosis, spongiosis, and neurodegeneration [2] which invariably leads to death. [doi.org]

There is no treatment available for these diseases. [ncbi.nlm.nih.gov]

Pathophysiology A unifying feature of all the prionoses is their neuropathology. These illnesses tend to affect the gray matter of the central nervous system (CNS), producing neuronal loss, gliosis, and characteristic spongiform change. [emedicine.com]

Thus, the propagation of nonneuronal PrPSc is not pathogenic, but arresting the continued conversion of PrPc to PrPSc within neurons during scrapie infection prevents prion neurotoxicity. [ncbi.nlm.nih.gov]

We found that depleting endogenous neuronal PrP c in mice with established neuroinvasive prion infection reversed early spongiform change and prevented neuronal loss and progression to clinical disease. [doi.org]

Prevention Properly sterilizing medical equipment may prevent the spread of the disease. If you have or may have CJD, you should not donate organs or tissue, including corneal tissue. [columbianeurology.org]
