Answer 1

The most likely diagnosis for the 55-year-old man described is Catatonia.

Step-by-step explanation:

The most likely diagnosis for the 55-year-old man described is Catatonia. Catatonia is a condition characterized by a state of unresponsiveness and immobility. The patient's presentation of stopped responding, lack of eating and sleeping, poor hygiene, and resistance to movement are all consistent with catatonia. The normal vitals and EEG also support this diagnosis.
