Psychotic symptoms tend to diminish as the individuals age, but negative symptoms tend to persist. [27] Prominent negative symptoms at disease onset, including alogia, are good predictors of worse outcomes. [26] [28] Negative symptoms can arise in the presence of other psychiatric symptoms. Positive symptoms are a common cause of apathy, social ...
Alogia, a TD traditionally classified as a negative symptom, can be separated into two types: poverty of speech content (a disorganization symptom) and poverty of speech, response latency, and thought blocking (negative symptoms). [115] Positive-negative-symptom diametrics, however, may enable a more accurate characterization of schizophrenia ...
Positive symptoms refer to those behaviors or condition that are present in schizophrenia but that are not present under typical conditions (hallucinations, delusions). Negative symptoms refer to those behaviors that are conspicuous because of their absence (grooming, language, communication). Several measures or rating scales have been ...
Some researchers have suggested that dopamine systems in the mesolimbic pathway may contribute to the 'positive symptoms' of schizophrenia, [1] [2] whereas problems concerning dopamine function within the mesocortical pathway may be responsible for the 'negative symptoms', such as avolition and alogia.

[6] [2] [21] [4] [7] Alogia (poverty of speech) and asociality (lack of social interest) are associated with DDM as well. [20] [7] Often however, a spectrum of DDM is defined encompassing apathy, abulia, and akinetic mutism, with apathy being the mildest form and akinetic mutism being the most severe or extreme form.
In schizophrenia, asociality is one of the main five "negative symptoms", with the others being avolition, anhedonia, reduced affect, and alogia. Due to a lack of desire to form relationships, social withdrawal is common in people with schizophrenia.
Simple-type schizophrenia is characterized by negative ("deficit") symptoms, such as avolition, apathy, anhedonia, reduced affect display, lack of initiative, lack of motivation, low activity; with absence of hallucinations or delusions of any kind.
Negative symptoms include alogia (lack of speech), blunted affect (reduced intensity of outward emotional expression), avolition (lack of motivation), and anhedonia (inability to experience pleasure). [22] Negative symptoms can be more lasting and more debilitating than positive symptoms of psychosis.
