Logoclonia

Logoclonia

Logoclonia is the tendency for a patient to repeat the final syllable of a word when speaking; hence it is one of the reiterative speech disorders (cf. echolalia, palilalia). It may be described as the festinating repetition of individual phonemes. Logoclonia has also been used to describe continuous perseveration.
Logoclonia is an indicator of bilateral brain injury, usually involving subcortical structures, and may be seen in the late stages of dementia of Alzheimer type (but not in semantic dementia).
