ObjectivesThe literature on the palilalia is relatively rich, probably because it affects several diseases: Parkinson's disease, syndrome of Gilles de la Tourette, Pick's disease, epilepsy, etc. The author, studying precisely palilalia in Alzheimer's disease to a severe stage, ran into a field of desert research. It offers an account of a case study, that of Mrs. L., that raises questions on one hand the possible causes of palilalia, on the other treatment to achieve. If, until now, the causes are defined primarily neurological and treated with pharmacological treatments, it seems that a method of non-drug treatments can sometimes have benefits on palilalia. Patient and methodThe patient in question suffered from Alzheimer's disease to a severe stage, she had many “behavioral and psychological symptoms of dementia” as perambulation, motor and gestural stereotypies, and especially palilalia. The ability to converse with Mrs. L. was profoundly altered, she no longer had access to a speech punctuated with a lexicology and had only a few words, syllables, or sounds of mouth that she repeated indefinitely to try to be heard. The author, a clinical psychologist who accompanied her for many months, tried to appease these verbal manifestations which generates among other residents of the nursing home anxiety, agitation, and aggression. Thus, for many weeks, the author undertook to repeat with her the syllables or words spoken on a different pace, or sang to validate the speech acts of the patient and to better preserve the environment in which it lives. ResultsRepeat the syllables with the patient first allowed her to pronounce other syllables or to conjure a few words. Repeat the syllables on a different pace had the surprising effect of reducing and then stop a few minutes palilalic phenomenon. This method having its limits over the deteriorating health status and increased speech disorders of Mrs. L., the production of long notes sung by the psychologist or the fact of singing syllables of the patient presented longer-lasting effects but unsystematic. ConclusionsIf our hypothesis binding palilalia and anxiety generated by the environment proves to be reinforced in the future by other clinical cases, it would be a considerable advance on the palilalic phenomenon so far only treated by pharmacological treatments. Along the lines of Hate Health Authority, the non-drug approach to ecology of the subject's environment, its preservation, seem to have appeasing effects, including on palilalia. Responding to a painful affect (marked in palilalia by a rapid rate of repetition) with a more pleasant affect (the psychologist using a slower pace) helped mitigate or stop the palilalia. Sing it introduced yet more benefits. Therefore, develop a method of treatment by therapeutic mediation, but here the song remains the possibilities opened appears sensible. An essential condition is still worth noting: these methods worked only on condition of transfer between Mrs. L. and psychologist.
