refers to the repetition of words, phrases, or sentences; however, echolalic patients repeat others' words, while palilalic patients repeat their own. Palilalia (say it five times fast and you ARE palilalic) is seen in a number of neurologic and psychiatric disorders, including Tourette's syndrome
, where patients will (seemingly involuntarily) spit out the same phrase over and over again. The repetition seen in patients with Alzheimer's disease
or other forms of dementia
is a bit different--instead of being a tic
, it generally occurs because the patient has forgotten what he or she just told you.
In noders, palilalia is generally a result of reposting form data (don't do it!)
