These are called positive symptoms, meaning they occur in people with schizophrenia but not in the general population.

这些被称为阳性症状——只有精神分裂症患者才会出现，一般人不会有。

Although the symptoms can be broadly categorized into three major areas: positive symptoms, negative symptoms, and cognitive symptoms.

尽管如此，这些症状大致可以分为三个主要类别：阳性症状、阴性症状与认知障碍。

They can be very effective in reducing positive symptoms, which are linked to an excess of dopamine in particular brain pathways.

对于减轻阳性症状效果显著，因为这些症状和大脑中特定通路的多巴胺含量过高有关。

Four of them are the positive symptoms, meaning things that you do, that you have that's unusual.

其中四个是阳性症状，意思是你所做的事情，你有不寻常的事情。

Broadly, most psychotic symptoms fall into three general categories traditionally used by psychologists: positive, negative, and disorganized symptoms. Positive symptoms are not what they sound like.

从广义上讲，大多数精神病症状可分为心理学家传统上使用的三大类：阳性症状、阴性症状和紊乱症状。阳性症状并不像听起来那样。

Hallucinations are a second type of positive symptom, and can be any kind of sensation that's not actually there, including visual but also including auditory sensations, like hearing voices or commands.

幻觉是第二种阳性症状，这是一种事实上不存在的感觉，可以涉及任何一种感官，可以是视觉，也可以是听觉，比如听到（实际上不存在的）声音或命令。

In schizophrenia, patients have positive symptoms which aren't positive in the sense that they're helpful, but positive in the sense that they're some new feature that doesn't have any " normal" or physiologic counterpart.

在精神分裂症患者的阳性症状中，所谓的“阳性”并不是指它们有益，而是指这些症状比较特殊，没有正常的生理功能与之对应。

Some researchers think that overly responsive dopamine systems might magnify brain activity in some way, perhaps creating hallucinations and other so-called positive symptoms as the brain loses its capacity to tell the difference between internal and external stimuli.

一些研究人员认为，过度反应的多巴胺系统可能会以某种方式放大大脑活动，当大脑失去区分内部和外部刺激的能力时，可能会产生幻觉和其他所谓的阳性症状。
