Step-by-step explanation:
The symptoms described in the question, such as feeling restless, experiencing a mind going blank, poor concentration, irritability, insomnia, and fatigue for more than a year, suggest the student may be experiencing a mental health issue. These symptoms, alongside a decline in academic performance, can potentially be indicative of conditions such as depression, anxiety, or even a sleep disorder that is affecting cognitive functions and overall well-being. It's crucial to seek medical advice to get a proper assessment and treatment plan. Conditions such as bipolar disorder and narcolepsy, for example, could be underlying factors, as they can significantly disrupt sleep, mood, and cognitive abilities.
