considered to be multifactorially inherited

Multifactorial inheritance means that "many factors"

where a combination of genes from both parents, in addition to unknown environmental factors, produce the trait or condition

factors are usually both genetic and environmental

Often, one gender (either males or females) is affected more frequently than the other in multifactorial traits

means that one gender is more likely to show the problem

Slightly more males develop schizophrenia in childhood, however, by adolescence schizophrenia affects males and females equally.

Although schizophrenia affects men and women equally, symptoms in men generally begin earlier than in women

schizophrenia first appears in men during their late teens or early 20s

women, schizophrenia often first appears during their 20s or early 30s.

schizophrenia affects 2.7 million Americans

child born into a family with one or more schizophrenic family member has a greater chance of developing schizophrenia than a child born into a family with no history of schizophrenia.

chance for a sibling to also be diagnosed with schizophrenia is 7 to 8 percen

If a parent has schizophrenia, the chance for a child to have the disorder is 10 to 15 percen

Risks increase with multiple affected family members.

Distorted perception of reality (i.e., difficulty telling dreams from reality) Confused thinking (i.e., confusing television with reality) Detailed and bizarre thoughts and ideas Suspiciousness and/or paranoia (fearfulness that someone, or something, is going to harm them) Hallucinations (seeing, hearing, or feeling things that are not real such as hearing voices telling them to do something) Delusions (ideas that seem real but are not based in reality) Extreme moodiness Severe anxiety and/or fearfulness Flat affect (lack of emotional expression when speaking) or inability to manage emotions Difficulty in performing functions at work and/or school Exaggerated self-worth and/or unrealistic sense of superiority of one's self Social withdrawal (severe problems in making and keeping friends ) Disorganized or catatonic behavior (suddenly becoming agitated and confused, or sitting and staring, as if immobilized) Odd behaviors

The symptoms of schizophrenia are often classified as positive (symptoms including delusions, hallucinations, and bizarre behavior), negative (symptoms including flat affect, withdrawal, and emotional unresponsiveness), disorganized speech (including speech that is incomprehensible), and disorganized or catatonic behavior (including marked mood swings, sudden aggressive, or confusion, followed by sudden motionlessness and staring).

diagnosed by a psychiatrist

Specific treatment for schizophrenia will be determined by your physician based on: Your age, overall health, and medical history Extent of the disease Your tolerance for specific medications, procedures, or therapies Expectations for the course of the disease Your opinion or preference

Types of treatment that may be helpful to an individual with schizophrenia may include: Medications (also called psychopharmacological management; to reduce the symptoms of schizophrenia), including the following: Neuroleptics--a specialized class of medications used to treat schizophrenia. Neuroleptics are used primarily to treat the pervasive, intrusive, and disturbing thoughts of a person with schizophrenia. They are designed to help minimize the severity of delusions and hallucinations the individual is experiencing. Antipsychotic medications--medications that act against the symptoms of psychotic illness, but do not cure the illness. However, these medications can reduce symptoms or reduce the severity of symptoms; a specialized class of medications used to treat schizophrenia. Individual and family psychotherapy (including cognitive and behavioral therapy) Specialized educational and/or structured activity programs (i.e., social skills training, vocational training, speech and language therapy) Self-help and support groups

Preventive measures to reduce the incidence of schizophrenia are not known at this time

Extensive and unusual loss of memory pertaining to personal information another feature of DID

Differential diagnosis generally involves ruling out the effects of chemical substances and medical (as opposed to psychological) conditions. When evaluating children, it is also important to ensure that symptoms are distinguishable from imaginary play (American Psychiatric Association, 2000).

In clinical populations, the estimated prevalence of DID ranges from 0.5 to 1.0% (Maldonado, Butler, & Spiegel, 2002). In the general population, estimates of prevalence are somewhat higher, ranging from 1-5% (Rubin & Zorumski, 2005). Females are more likely to receive a diagnosis of DID, at a ratio of 9:1 (Lewis-Hall, 2002

High percentages of individuals with DID have comorbid diagnoses of Post-Traumatic Stress Disorder or Borderline Personality Disorde

DID commonly have a previous diagnosis of Schizophrenia. However, this most likely represents a misdiagnosis rather than comorbidity, du

Other possible comorbid disorders involve substance abuse, eating disorders, somatoform disorders, problems of anxiety and mood, personality disorders, psychotic disorders, and organic mental disorders (ISSD, 2005), OCD, or some combination of conversion and somatoform disorder

Other factors influencing a poor prognosis include remaining in abusive situations, involvement with criminal activity, substance abuse, eating disorders, or antisocial personality features

the average age of diagnosis is thirt

One study found that the risk of developing a dissociative disorder (DD) increased seven times with a child’s exposure to trauma.

Dissociative Identity Disorder is linked to childhood abuse in 95-98% of the cases

Studies on genetic factors contributing to DID present mixed findings. However, one study involving dyzogotic and monozygotic twins found that considerable variance in experiences of pathological dissociation could be attributed to both shared and non-shared environmental experiences, but heritability appeared to have no effect (Waller & Ross, 1997).

Treatment most commonly follows a framework of “1) safety, stabilization and symptom reduction, 2) working directly and in depth with traumatic memories, and 3) identity integration and rehabilitation” (p. 89).

A study involving 280 outpatient participants (98% DID diagnosis) from five different races (Caucasian, African American, Hispanic, Asian, and Other) demonstrated the effectiveness of a similar five-phase model in reducing symptoms of dissociation.

This study clarifies the mechanism and function of memory in various dissociative states and helps explain why trauma might result in the development of alters.

They also may have trouble organizing their thoughts and expressing themselves

speech and behavior can be so disorganized that they may seem frightening to others

Jekyll-and-Hyde" type of split personality

Schizophrenia literally means "a split mind," and this may be where the misconception of split personality took root.

difficulty functioning in society, at work, and in school

But the symptoms of schizophrenia vary widely from one person to another. In some people, the dissociated feelings caused by the illness are a constant part of life. In others, the symptoms will come and go. People with schizophrenia do not always act abnormally. They may appear perfectly responsible and in control, even when experiencing hallucinations or delusions.

Schizophrenia cannot be cured

Psychologically distressed girls are at risk for teen childbearing and vice versa, even if the two things usually do not cause each other,” Mollborn said. “This could help educators and clinicians identify at-risk adolescents.”

One of the best ways to prevent teen pregnancy is for teens to have long-term goals and good self-esteem, Merritt added.

All of the animals' symptoms were similar to that of humans - they rapidly develop severe respiratory disease, stop eating and some die.

"All viruses can mutate, but the influenza virus raises special concern because it can change whole segments of its viral sequence fairly easily," Loehr said.

Veterinarians who encounter possible cases of this phenomenon can obtain more information from Loehr or Jessie Trujillo at Iowa State University. They are doing ongoing research to predict, prevent or curtail emergent events.

“We worry a lot about zoonoses, the transmission of diseases from animals to people,” said Christiane Loehr, a professor at the OSU College of Veterinary Medicine. “But most people don’t realize that humans can also pass diseases to animals, and this raises questions and concerns about mutations, new viral forms and evolving diseases that may potentially be zoonotic. And, of course, there is concern about the health of the animals.”

H1N1 (“swine flu“) and H5N1 (“bird flu”)

The first recorded instance, described in an article published by the team in Veterinary Pathology, took place in Oregon in 2009.

While a cat owner was hospitalized with H1N1, both of her cats (which stayed indoors and had no contact with other sick people or animals) came down with flu-like symptoms and eventually died. A postmortem analysis of their lungs and nasal cavities turned up the H1N1 virus

“It’s reasonable to assume there are many more cases of this than we know about, and we want to learn more,” Loehr said.

“Any time you have infection of a virus into a new species, it’s a concern, a black box of uncertainty,” Loehr noted.

this news might trigger immediate concern,

the flu could be passed from human to pet, mutate into a more dangerous form,

“We don’t know for sure what the implications might be, but we do think this deserves more attention.”

Compared to the normal control group, the children with ADHD showed abnormal functional activity in several regions of the brain involved in the processing of visual attention information

"What this tells us is that children with ADHD are using partially different functional brain pathways to process this information, which may be caused by impaired white matter pathways involved in visual attention information processing," Dr. Li said.

According to the National Institute of Mental Health, there is no single test capable of diagnosing a child with the disorder. As a result, difficult children are often incorrectly labeled with ADHD while other children with the disorder remain undiagnosed.

ADHD diagnoses depend on a child's age relative to classmates and the teacher's perceptions of whether the child has symptoms.

ADHD is the most commonly diagnosed behavioral disorder for kids in the United States, with at least 4.5 million diagnoses among children under age 18, according to the Centers for Disease Control and Prevention.

However, there are no neurological markers for ADHD

Overall, the study found that about 20 percent -- or 900,000 -- of the 4.5 million children currently identified as having ADHD likely have been misdiagnosed.
