Using poverty of speech as a case study to explore the overlap between negative symptoms and cognitive dysfunction

Conclusions
Some negative symptoms are conceptually related and therefore not fully distinct from cognitive impairments. Here, we demonstrate that clinical ratings of alogia and words produced during a cognitive test are tapping into a similar construct. Whether a specific deficit is classified as a negative versus cognitive symptom may be matter of semantics rather than reflective of divisible underlying processes.

I have alogia as my worst negative symptom. I think I have either poverty of speech or reduced verbal fluency. It is either a negative or cognitive symptom.
