Final answer:
Silvio likely exhibits signs of Major Depressive Disorder (MDD), characterized by a severely depressed mood, loss of interest in activities, significant changes in sleep and eating patterns, and thoughts of sui cide, among other symptoms. The correct answer is C.
Step-by-step explanation:
Based on the symptoms provided – a lack of interest in previously enjoyable activities such as video games, excessive sleeping (16-18 hours a day), thoughts of self-harm, difficulty making decisions, and significant weight loss – Silvio likely exhibits signs of Major Depressive Disorder (MDD). MDD is a serious mental health condition characterized by a persistently depressed mood and a loss of interest or pleasure in activities, which causes significant impairment in daily life. Symptoms also include significant changes in sleep and eating patterns, trouble concentrating, feelings of worthlessness, and recurring thoughts of death or sui cide.
While Seasonal Affective Disorder (SAD) and Bipolar Disorder also involve mood disturbances, the specific combination of symptoms such as the prolonged depressed mood, self-harm ideation, and significant weight loss are more indicative of MDD. SAD typically involves symptoms like increased appetite and sleepiness during specific seasons, and Bipolar Disorder involves episodes of mania or hypomania, which are not described in Silvio's case. Generalized Anxiety Disorder (GAD) typically involves excessive worry and anxiety, not predominantly low mood or loss of interest. The correct answer is C.
