Document Summary
Positive and negative symptoms: apathy, lack of emotion, poor or non- existent social functioning, hallucinations, delusions, and racing thoughts to name a few. Cognitive symptoms: disorganized thoughts, difficulties concentrating or following instructions, difficulties completing tasks and memory problems. Whether or not someone will be ill is a result of predisposition to illness, and this can be a result of changes in genetic hardware or software: differences in dna sequences. We are talking about changes in genetic hardware: change occurred in the coding part of the gene, when different amino acids are sequenced together to form a protein with a specific function, qualitative changes, epigenetic differences. We are focusing on the genetic software, Mutations that take place in the non-coding part of a gene. Changes in genes can occur later in life as well by substances, or x-rays for example. A biological mutation can result from an external stimulus.
