Abstract
ummary & Conclusion
Major depressive disorder (MDD) is a serious and disabling
illness of very high prevalence as it affects approximately 216 million
people in 2015 (3% of the global population). Major depressive
disorder is linked to diminished role functioning and quality of life,
medical comorbidity, and mortality . The World Health Organization
(WHO) has ranked depression as the second leading cause of disability
worldwide.
Whilst major depressive disorder is primarily characterized by
emotional symptoms such as low mood and loss of interest and
pleasure, individuals with depression have also been found to display
impairments in cognitive and interpersonal functioning.
The ability to correctly interpret social signals and information
is crucial for successful interpersonal interaction , this requires
exercising a broad range of verbal and non-verbal cues, including facial
expressions, tone of speech, body language, and the mental states of
others (theory of mind). These skills are referred to as social cognition
which form an important component of cognitive functioning .
Social cognition can be defined as the mental operations that
underlie social interactions, including perceiving, interpreting, and
generating responses to the intentions, thoughts, feelings, and behaviors
of others ,This include emotion-processing, theory of mind, and social
perception and knowledge.
