Understanding CJD and Its Symptoms

The video explains the role of proteins in neurons and introduces Creutzfeldt-Jakob Disease (CJD), a rare prion disease. It follows Anthony, a patient with CJD, detailing his symptoms like memory loss, myoclonus, and ataxia. The video describes how prion proteins misfold, leading to cell death and disease spread. It outlines the four types of CJD: sporadic, familial, iatrogenic, and variant. Diagnostic methods like EEG, MRI, and CSF analysis are discussed, along with the disease's prognosis. The video concludes with a recommendation to watch related content.

What is the primary function of proteins in neurons?

• To provide structural support

• To carry out tasks within the neuron

• To store genetic information

• To transmit electrical signals

What symptom did Anthony first develop?

• Ataxia

• Akinetic mutism

• Memory impairment

• Myoclonus

What are the quick involuntary jerky movements observed in Anthony called?

• Ataxia

• Myoclonus

• Tremors

• Seizures

What is the medical term for an unsteady gait?

• Myoclonus

• Ataxia

• Dystonia

• Tremor

What happens to prion proteins when they misfold?

• They become inactive

• They dissolve in the cell

• They repair themselves

• They self-replicate and convert normal proteins

Which form of CJD is caused by a mutation in the prion gene?

• Sporadic CJD

• Iatrogenic CJD

• Familial CJD

• Variant CJD

How can humans contract Variant CJD?

• By spontaneous mutation

• Through genetic inheritance

• Through surgical treatments

• By consuming infected food products

What appearance does the brain have under a microscope in CJD patients?

• Inflamed and swollen

• Scarred and fibrous

• Sponge-like with vacuoles

• Smooth and uniform

What is the special type of coma called where a person becomes mute and motionless?

• Akinetic mutism

• Locked-in syndrome

• Vegetative state

• Catatonia

What is the typical prognosis for someone diagnosed with CJD?

• Gradual improvement over time

• Recovery within a year

• Lifelong management of symptoms

• Death within one year from onset
