These are multiple choice polls.
Positive symptoms
Positive symptoms are psychotic behaviors not seen in healthy people. People with positive symptoms often “lose touch” with reality. These symptoms can come and go. Sometimes they are severe and at other times hardly noticeable, depending on whether the individual is receiving treatment.
- Hallucinations
- Delusions
- Thought disorders
- Movement disorders
Negative symptoms
Negative symptoms are associated with disruptions to normal emotions and behaviors. These symptoms are harder to recognize as part of the disorder and can be mistaken for depression or other conditions.
- “Flat affect”
- Lack of pleasure in everyday life
- Lack of ability to begin and sustain planned activities
- Speaking little, even when forced to interact.
Cognitive symptoms
Cognitive symptoms are subtle. Like negative symptoms, cognitive symptoms may be difficult to recognize as part of the disorder. Often, they are detected only when other tests are performed.
- Poor “executive functioning”
- Trouble focusing or paying attention
- Problems with “working memory”
