A big question would be what adolescent schizophrenia actually is? In all cases, there are positive and negative symptoms. A child's life can be radically changed if they are not diagnosed or treated early enough. Unfortunately, this disorder can sometimes become a lifelong struggle. The child's parents and family always have to worry about how their child will react to something and what those problems might become. To answer the question posed earlier, adolescent schizophrenia is an interesting and confusing disorder in which the brain becomes severely shut down. There are 4 main types of schizophrenia, all based on age. Very early onset schizophrenia, VEOS, occurs before the child's 13th birthday. Early-onset schizophrenia, EOS, will be seen before the 18th birthday. Childhood schizophrenia, COS, which occurs in the prepubertal stage, in relation to the child's chronological age, will be manifested when the child is 12 years old or younger. Finally, adolescent schizophrenia appears between the ages of 13 and 17. Some of the main causes of this disorder are neurobiological and neurophysiological difficulties and genetic problems. The problematic part of the genes is located on chromosomes 6, 8, 10, 13, 18 and 22. In case of neurobiological problems, some symptoms would be a reduction in brain volume, changes in the serotonergic and noradrenergic systems. Neurophysiological aspects include decreased IQ, reduced language perception, poor speech production, and formal thought disorders. Many other problems can occur with schizophrenia. Some of the main recurring problems associated with this disorder are hallucinations and delusions, and there is actually a big difference between the two. Hallucinations can be auditory, gustatory or ...... middle of paper ......tes to be diagnosed with another type of disorder. These are called comorbid conditions. Some main disorders that may be associated with EOS are anxiety and depression. Some problems that can arise from comorbid conditions are that the child may have cognitive difficulties and developmental delays. Before doctors actually examine the child with comorbidities, they will think he or she has an autistic disorder (McDonell & McClellan). In children with EOS, substance abuse can become a major problem as they grow up. One of the most significant abuses is nicotine (NIMH, 2007). A child with schizophrenia definitely leads a completely different life than a child without this disorder. Simple tasks like brushing teeth and dressing can turn into an extremely difficult experience not only for the child but also for the parents..
