Answer: somatization
Step-by-step explanation:
Paul Briquet first described Briquet's syndrome in 1859, and he stares that it occurs when patients have the feeling that for a larger part of their lives, they've been sick and then complain about different symptoms related to different parts of their body system.
In the above example, Blake started experiencing erectile dysfunction, followed by chest pain. He then had diarrhea and double-blindness. This shows he's suffering from Briquet's syndrome also called somatization pattern.
