Akinesia
Definition
Severe clinical symptom consisting of the total inability or complete loss of the capacity to initiate and execute voluntary muscular movements, in the absence of actual motor paralysis. This phenomenon is caused by dysfunctions in the basal ganglia and dopaminergic pathways of the brain, representing a cardinal manifestation encountered in advanced stages of Parkinson's disease, extrapyramidal parkinsonian syndromes, or catatonic states.
