Do you know the possible reason behind Tina's recent behavior?

What are the symptoms that suggest Tina is experiencing?

A. dissociative fugue

B. generalized anxiety disorder

C. dysthymic disorder

D. manic episode

Final answer:

Tina's symptoms suggest that she is most likely experiencing a manic episode.

Explanation:

You asked whether Tina, who exhibits symptoms of hyperactivity and grandiose thinking while getting very little sleep, may be experiencing a dissociative fugue, generalized anxiety disorder, dysthymic disorder, or a manic episode. From the information provided, it suggests that Tina is most likely experiencing a manic episode.

Mostly associated with bipolar disorder, manic episodes are characterized by an extended period of elevated, expansive, or irritable mood, and increased goal-directed activity or energy. These episodes might last for at least one week, and could involve racing thoughts, inflated self-esteem or grandiosity (like Tina's conviction about her unpublished novel), decreased need for sleep, and hyperactivity - all conditions that match Tina's symptoms.
