astasia-abasia

The inability to stand or walk despite possessing good motor strength and conserved voluntary coordination. Symptomatic astasia-abasia has been associated with lesions affecting the pontomesencephalic region, thalamus, corpus callosum, or cingulate cortex.
Aetiology Usually psychogenic, less commonly organic (e.g., alcohol-induced).
Pathogenesis Uncertain; organic (i.e., not psychogenic) astasia-abasia has been linked to hyperperfusion (by SPECT) of the mesencephalic and subthalamic locomotor regions of the dorsal brainstem and subthalamus, and abnormal neural activity.
