Neglected negative symptoms in schizophrenia: what every psychiatrist needs to know

Conference Paper


Abstract


  • Negative symptoms have been divided into several domains, contrasting negative and positive symptoms

    which are different in their nature, onset, progression and response to treatment. The negative symptoms

    of schizophrenia can be divided into two domains. Avolition/apathy includes the individual symptoms of

    avolition, asociality and anhedonia. Diminished expression includes blunted affect and alogia. Until now,

    causes and treatment of negative symptoms have remained a major challenge, which is partially related to

    the focus on negative symptoms as a broad entity. This presentation reviews the history of negative

    symptoms in diagnosis and how different approaches have been utilised to consider negative symptoms in

    the concept of schizophrenia. The role of various clinical and other factors in complicating the

    presentations of negative symptoms and an attempt to differentiate it from other disorders are

    highlighted. Contemporary assessments and neurobiological basis of negative symptoms are discussed.

    This presentation also reviews the current modalities of treatment of negative symptoms.
