Parkinson's Disease [Part 1] | The 4 Cardinal Signs

The video discusses Parkinson's disease, focusing on its impact on the basal nuclei and the role of the substantia nigra in dopamine production. It explores genetic and environmental causes, using Michael J Fox and Muhammad Ali as examples. The video explains the four cardinal signs of Parkinson's, remembered by the acronym TRAP: tremor, rigidity, akinesia, and postural instability, detailing each symptom and its effects.

• To produce serotonin

• To generate dopamine

• To control heart rate

• To regulate blood pressure

Which of the following is NOT a cardinal sign of Parkinson's disease?

• Bradykinesia

• Intention tremor

• Rigidity

• Resting tremor

What does the 'A' in the TRAP acronym for Parkinson's disease stand for?

• Ataxia

• Akinesia

• Aphasia

• Agnosia

Which symptom of Parkinson's disease is typically observed later than the others?

• Postural instability

• Resting tremor

• Rigidity

• Bradykinesia

In Parkinson's disease, falls are most commonly in which direction?

• Forward

• Sideways

• Backward

• Upward
