akineisia
Pronunciation: ay-ki-NEE-see-ah
Complete or near-complete loss of voluntary movement, often presenting as severe motor slowing in psychiatric patients.
Full Definition
Akinesia is a neurological side effect characterized by the absence or poverty of voluntary movement, distinct from bradykinesia (slowed movement). In psychopharmacology, it commonly occurs as an extrapyramidal side effect of antipsychotic medications, particularly first-generation agents. Patients may appear statue-like with reduced spontaneous movement, facial expression, and gesture. Recognition is crucial for editors reviewing psychiatric case reports as it's often confused with catatonia or severe depression.
Usage
Usage note: Often misspelled as 'akinesia' - note the correct spelling lacks the 's'.
