Creutzfeldt–Jakob disease (CJD), also known as subacute spongiform encephalopathy or neurocognitive disorder due to prion disease, is a fatal neurodegenerative disease. [ 4 ] [ 1 ] Early symptoms include memory problems, behavioral changes, poor coordination, and visual disturbances. [ 4 ]
Creutzfeldt-Jakob disease itself has four main forms, the sporadic (sCJD), the hereditary/familial (fCJD), the iatrogenic (iCJD) and the variant form (vCJD). These conditions form a spectrum of diseases with overlapping signs and symptoms.
vCJD is a separate condition from classic Creutzfeldt–Jakob disease (though both are caused by PrP prions). [9] Both classic and variant CJD are subtypes of Creutzfeldt–Jakob disease. There are three main categories of CJD disease: sporadic CJD, hereditary CJD, and acquired CJD, with variant CJD being in the acquired group along with ...
Hereditary diseases, particularly hemophilia, were recognized early in Jewish history, even being described in the Talmud. [6] However, the scientific study of hereditary disease in Jewish populations was initially hindered by scientific racism, which was based on racial supremacism.

Electroencephalogram (EEG) is used to distinguish kuru from Creutzfeldt–Jakob disease, a similar encephalopathy (any disease that affects the structure of the brain). [28] EEGs search for electrical activity in the person's brain and measure the frequency of each wave to determine if there is an issue with the brain's activity. [29]
Creutzfeldt–Jakob disease, a fatal degenerative brain disorder caused by prions involving the cerebral cortex, the basal ganglia and the spinal cord.; Adrenoleukodystrophy, a rare demyelination disorder also known as Siemerling-Creutzfeldt disease that causes damage to the myelin sheaths of neurons in the brain, resulting in seizures and hyperactivity.
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child.
GSS is a disease that progresses slowly, lasting roughly 2–10 years, with an average of approximately five years. [8] [1] Symptoms as clumsiness and unsteadiness when walking at the beginning of the illness. Muscle jerking (myoclonus) is much less common than in Creutzfeldt-Jakob disease.
