Negative symptoms in schizophrenia can be so disabling that they interfere with a person's ability to attend school, begin a fulfilling career, and even live independently.
In a recent study published by JAMA Psychiatry, UNLV psychology professor Daniel Allen and colleagues suggest a new way to classify the negative symptoms of schizophrenia, which may influence research and treatment in years to come.
Literature - Symptoms - Schizophrenia - Categories - Allen
Previous literature suggested that the negative symptoms of schizophrenia should be placed into two categories. Allen and his colleagues suggest that that view is too simplified. To reflect the complexity of the disease, and to hone in on more specific treatments, Allen suggests that the symptoms be placed into five categories.
Allen says it is important to understand the symptoms of schizophrenia so we can measure them accurately. "Correctly measuring these symptoms allows us to judge whether or not the person is improving or getting worse," Allen said. "Or whether or not we're developing medications that are actually helpful for the disorder that they have, or not helpful."
Symptoms - Schizophrenia - Disorders - People - Doctors
Measuring symptoms in schizophrenia and other mental disorders can be difficult because it is heavily dependent on what people tell their doctors about the symptoms they are experiencing. It differs from a disease like cancer, where the effectiveness of treatments can be measured against the size of a tumor, and whether it's shrinking.
Therefore, scientists like Allen must be as specific as possible when assessing people with schizophrenia. Great care is taken to make sure that questions are asked about the kinds of...
