Bradykinesia

BRADYKINESIA (from Greek bradys- slow and kinesis- movement), general slowness of movements, represents one of the essential symptoms of the pallidal symptom complex (paralysis, post-encephalitic parkinsonism, Wilson's disease, pseudosclerosis, etc.). B. can exist in the absence of paralysis and paretic phenomena and in the absence of significant changes in muscle tone. Bradibasia (from Greek basis - gait, step) - slowness of walking. Bradylalia (from Greek logos - word), bradiphasia (from Greek phasis - speech) and bradiphrasia (from Greek phrasis - expression, turn of speech) - slowness of speech. Bradilexia (from Greek lexis - syllable, speech) - slowness of reading. Bradipraxia (from Greek praxis - action) - slowness of action. Bradylalia (from Greek lalia - speech) - slow but correctly coordinated speech; occurs in childhood and in adults; articulation becomes difficult, requiring considerable effort; speech becomes so slow that any somewhat prolonged conversation becomes very difficult due to fatigue; often bradylalia occurs in convalescents. It is often an early symptom of disseminated sclerosis, brain tumor, Thomsen's disease, Friedreich's disease, etc. In childhood, a spastic form occurs, in which monotonous speech is observed, accompanied by jerky movements of the head and upper part of the body; sometimes there is asynchrony between abdominal and thoracic breathing. All the above conditions are included as constituent parts in the concept of bradykinesia.
