A nurse is caring for a client who has schizophrenia. Which of the following findings should the nurse identify as a comorbidity to this condition?

A. A lack of emotions, also known as flat affect or emotional blunting, is a common negative symptom of schizophrenia. It refers to a reduced range or intensity of emotional expression, such as reduced facial expressions, tone of voice, or gestures.

B. Paranoia is not a negative symptom but rather a positive symptom of schizophrenia.

C. Confusion may occur in schizophrenia, but it is not specific to negative symptoms. Confusion can be a result of various factors, including medication side effects, acute psychosis, or cognitive deficits.

D. Distorted beliefs, such as delusions, are considered positive symptoms rather than negative symptoms of schizophrenia.

B. Fluctuating cognition and visual hallucinations are characteristic features of Lewy body dementia (LBD). LBD is a type of dementia that involves abnormal protein deposits called Lewy bodies in the brain. These deposits can cause fluctuations in cognitive abilities, leading to periods of clarity alternating with confusion or disorientation. Visual hallucinations are also common in LBD, often involving seeing people, animals, or objects that are not present.

A. Prion diseases are not commonly associated with fluctuating cognitive function.

C. HIV infection can cause a range of neurological complications, but they usually manifest differently from the symptoms described in the scenario.

D. Symptoms of TBI-related dementia would depend on the severity and location of the brain injury, but they often involve cognitive deficits consistent with the area of brain damage
