Answer:
Somatoform disorder
Step-by-step explanation:
Somatoform disorder or Somatic disorder is a mental disorder that causes the person to experience pain, sexual symptoms or neurological symptoms that cannot be traceable to an actually physiological reason. In other words, there is not a physiological reason for the existence of this symptoms but yet, the symptoms are real and the person is not faking them. The symptoms usually get worse when the person is feeling stressed.
In this example, an airline pilot suddenly experiences loss of sensation in his arms right before takeoff and doctors are unable to find a physiological reason for this. He was probably feeling stressed about the flight, but even if he was not, we can see that he meets the criteria for the Somatoform disorder since he is experiencing neurological symptoms and there is no apparent physiological reason for them.
