from one topic to the next. Changes are based on understandable associations, play on
words, or distracting stimuli, but ideas are not well connected.

meanings

for the sounds of voices

actual external stimulation. The person may or may not recognize the experiences as
false. May be auditory, visual, olfactory, gustatory, tactile, or somatic.

grammatical words are dropped from speech "Well…..cat and…..up……..um, well,
um…forget it"
-Wernicke's aphasia the patient can speak effortlessly and fluently, but his words
often make no sense “the coffee cat looks crazy still”

of words. Abnormalities
