Q: What is festination in neurological exam?
Answer: Festination is an involuntary tendency to speed up when performing repetitive movements. It can be gait, handwriting and/or speech. It was originally described by Parkinson in 1817 in his original essay as festinating gait. It usually corelates with freezing of gait (FoG) and signifies late stages of Parkinson's disease.
