Negative symptoms are highly prevalent among individuals with schizophrenia and related disorders and have been linked to poor functioning and disability. Traditionally, these symptoms have been evaluated via in-person clinical interviews and observations. However, technological advances over the past 15 years have ushered the promise of employing digital technologies to enhance the assessment of negative symptoms. In this presentation, I will describe some of the challenges associated with traditional assessment methods of negative symptoms. Next, I will review emerging research on the use of digital technologies (e.g., actigraphy, smartphones, audio and video recordings of speech and facial expressions) in the assessment of negative symptoms. Finally, I will discuss future directions for research and clinical use in this area.
Negative symptoms are highly prevalent among individuals with schizophrenia and related disorders and have been linked to sedentary behaviors and poor aerobic fitness, suggesting a potential target for treatment development. In this presentation, I will review the research literature on the various exercise interventions employed among individuals with schizophrenia and related disorders, along with issues related to their application and feasibility. Next, I will review some of the neurobiological benefits of physical exercise and their relevance to brain circuitry underlying negative symptoms (i.e., neural reward-related pathways). Drawing on recent research publications, I will provide a detailed review of the benefits of moderate-to-vigorous and none-to-low intensity physical exercise interventions in alleviating negative symptoms. Finally, I will provide practical recommendations for the employment of physical exercise interventions among individuals with schizophrenia and related disorders to target negative symptoms.
