Transcript of DSM-5 EPPP Lecture Video: Parkinson’s Disease
NARRATIVE DEFINITION: Parkinson’s Disease is a progressive neurological disorder caused by the degeneration of dopaminergic neurons within the substantia nigra, a subcortical area related to voluntary motor movement, and the nigrostriatal pathway, a neural tract heading to the striatum from the substantia nigra. The neurotransmitter dopamine is involved in the coordination of smooth and complex movement; dopamine deficits result in impaired motor activity. Severely decreased levels of dopamine in individuals with Parkinson’s Disease cause the disorder’s most characteristic symptoms: resting tremor, rigidity, bradykinesia (i.e., slowness), and postural instability.
