Wikipedia
In psychology, alogia (Greek ἀ-, “ without”, and λόγος, “speech”), or poverty of speech, is a general lack of additional, unprompted content seen in normal speech. As a symptom, it is commonly seen in patients suffering from schizophrenia, and is considered as a negative symptom. It can complicate psychotherapy severely because of the considerable difficulty in holding a fluent conversation.
Alogia is often considered a form of aphasia, which is a general impairment in linguistic ability. It often occurs with intellectual disability and dementia as a result of damage to the left hemisphere of the brain. People can revert to alogia as a way of reverse psychology, or avoiding questions.
Alogia is a Serbian heavy metal band from Smederevo.
