Speech Changes, Causes, and Treatments of Alogia

Alogia is a thought disorder involving impaired thinking that manifests as impaired language abilities. A person with alogia may say fewer words or speak vaguely or repetitively. Alogia has associations with conditions like severe depression, schizophrenia, dementia, and autism, though it can occur in a healthy person, as well.

1. General Characteristics

The main signs of alogia are changes in speech and language use. Severity exists on a spectrum and the condition can occur alongside typical behaviors. People without neurological issues may experience alogia when feeling fatigued or under stress. Alogic speech may be present in certain disciplines that use language pedantically, as well as people with less education. Alogia can cause a person to slur their words, fail to pronounce consonants clearly, pause between words, or end statements as whispers.
