62.有關類思覺失調症（schizophreniform disorder）的敘述，下列何者最不適當？
(A)其症狀表現與思覺失調症相似，只是症狀持續時間大於1個月，少於6個月
(B)其盛行率無性別差異
(C)有半數以上會進展成思覺失調症
(D)抗精神病藥物的療效優於思覺失調症

發病後1月以上未滿6個月叫schizophreniform disorder,超過6個月就是schizophrenia

In the United States, schizophreniform disorder is much less common than schizophrenia, which affects 0.6% to 1.9% of people.

About one-third (33%) of people who receive a diagnosis of schizophreniform disorder will no longer have symptoms after six months. Most of the remaining two-thirds (66%) of people will eventually receive a diagnosis of schizophrenia or schizoaffective disorder. In other words, their symptoms last longer than six months.三分之二會發展成schizophrenia(所以也導致schizophreniform disorder較罕見?)

Schizophreniform disorder is equally prevalent among men and women. The most common ages of onset are 18–24 for men and 18–35 for women. While the symptoms of schizophrenia often develop gradually over a period of years, the diagnostic criteria for schizophreniform disorder require a much more rapid onset.^[1]

^{男女比相當,但發病年齡有差,男生早發病18-24歲,女生18-35歲}
