i read this about schizophrenia… could someone explain it

Schizophrenia is often described in terms of positive and negative (or deficit) symptoms.[16] the term positive symptoms refers to symptoms that most individuals do not normally experience but are present in schizophrenia. they include delusions, auditory hallucinations, and thought disorder, and are typically regarded as manifestations of psychosis. Negative symptoms are things that are not present in schizophrenic persons but are normally found in healthy persons, that is, symptoms that reflect the loss or absence of normal traits or abilities. Common negative symptoms include flat or blunted affect and emotion, poverty of speech (alogia), inability to experience pleasure (anhedonia), lack of desire to form relationships (asociality), and lack of motivation (avolition). Research suggests that negative symptoms contribute more to poor quality of life, functional disability, and the burden on others than do positive symptoms.[17]

i dont know but i wanna tell u that i know someone who is schizo and he cant speak clearly and when he wants to make conversation, he has to put so much effort into it that his hands shake a little—also, he plays the guitar but he cant really master it no matter how much he plays n practices but he plays okay though. oh! and he has a real hard time understanding deep or serious conversations– he loses focus really fast, he cant even seat and watch tv, he gets too anxious or inpatient. and lastly, he cant work! he cant handle the pressure of working, not even bagging groceries.
