- GSS is an extremely rare, fatal neurodegenerative disease
- It also classified with the transmissible spongiform encephalopathies (TSE) due to the causative role of prion protein.

Sign / Symptoms
Common symptoms are
- Pyramidal signs
- Symptoms start with Slowly developing dysarthria and cerebellar truncal ataxia and then to progressive dementia
- In the early stages people exhibit clumsiness and walking difficulties, then ataxia comes
- Loss of memory can be the first symptom of GSS.
- Extrapyramidal and pyramidal symptoms may mimic spinocerebellar ataxia
- Myoclonus is less frequently seen than in CJD
- Many patients also exhibit nystagmus, visual disturbances, and even blindness or deafness.
- Paralysis: Paraplegia / Paraparesis
- Seizures
Types
- Four clinical phenotypes are recognized:
- Typical GSS
- GSS with areflexia and paresthesia
- Pure dementia GSS
- CJD-like GSS
Diseases
- Typicaly includes progressive Cerebellar ataxia + Pyramidal tract signs + + , + + Dysesthesia
Research
- In my research, GSS is the best remedy of Alzheimer disease, because of Memory weakness + Psychosis/ Behavioral change + Impaired Concentration + Depression
Pyramidal signs / UMN
Corticospinal tract
- Spasticity / Spastic Paralysis
- Hyper Reflexia
Corticobulbar tract
- Paralysis of certain cranial nerves
- Pseudobulbar paralysis
- Dysphagia
- Dysarthria / Speech difficult
- Emotional lability / Pseudobulbar affect
- Hyper Reflexia
- Spasm
