However, it is often associated with the negative symptoms of schizophrenia. Alogia has been called a poverty of speech, or a reduction in the amount of speech. It is also known for a poverty in the content of speech, or speech that does not convey any meaningful information. These difficulties are because the person has difficulty mentally formulating his or her thoughts and words.
