Asserts that schizophrenia is caused in part by various disruptions in the normal maturational processes of the brain before or at birth. According to this hypothesis, insults to the brain during sensitive phases of prenatal development or during birth can cause subtle neurological damage that elevates individuals vulnerability to schizophrenia years later and adolescence and early adult hood. Some studies have found a link between exposure to influenza and other infections during prenatal development and an increased prevalence of schizophrenia. One study found a slight elevated incidence of schizophrenia in a group of people who were prenatally exposed to severe famine.

How can emotional reactions affect heart disease?
Cardiologists and laypersons have long voiced suspicions that strong emotional reactions might trigger heart attacks in individuals with coronary disease. Advances in cardiac monitoring have facilitated investigation of the issue. As suspected, laboratory experiments with cardiology patients have shown that brief periods of mental stress can trigger certain symptoms of heart disease. Mental stress can elicit cardiac symptoms in about 30 to 70% of coronary patients. Outbursts of anger can be particularly dangerous. A recent meta-analysis of available evidence concluded that in the two hours immediately following an outburst of anger, there is nearly a fivefold increase in an individuals risk for heart attack and more than a threefold increase in their risk for a stroke.

What structural abnormalities in the brain are associated with schizophrenia?
Cognitive deficit such as attention, perception and information processing problems suggest that schizophrenic disorders may be caused by neurological deficits. The most reliable finding is that CT scans and MRI scans suggest an association between enlarged brain ventricles and schizophrenic disturbance. Enlarged ventricles are assumed to reflect the degeneration of nearby brain tissue. The structural deterioration could be a consequence of schizophrenia, or it could be a contributing cause of the illness. Brain imaging studies have also uncovered other structural abnormalities, including reductions about gray matter and white matter in specific brain regions.

Experts have tended to explain this correlation by asserting that been diagnosed with heart disease makes people depressed, however, recent evidence suggests that the causal relations may just be the opposite. The emotional disfunction of depression may cause heart disease. One study found that participants who suffered from depression were 2.7 times more likely to die of heart disease during the follow up period than people who are not depressed. Because the participants had depressive disorder before heart attacks, account to be argued that their heart disease caused their depression. Overall, studies suggest that depression roughly doubles once chances of developing heart disease.

How do genetic factors play a role in mood disorders?
Genetic factors influence the likelihood of developing major depression and bipolar disorder. Twin studies have found a huge disparity between identical and fraternal twins and concordance rates for mood disorders. The concordance rate for identical twins is much higher. This evidence suggests that heredity can create a predisposition to move disfunction. Environmental factors probably determine whether this predisposition is converted into an actual disorder.
What causes autism?
Genetic factors make a major contribution to ASD. It must be attributed to some sort of brain abnormality, and the most reliable finding has been the ASD is associated with generalized brain enlargement that is apparent by the age of two. Children with autism appear to have 67% more neurons in the prefrontal cortex than other children do. Vaccinations do not cause autism, and this popular correlation was due to the fact that children get scheduled vaccinations around the same time the autism begins to show symptoms, however there is no scientific data suggesting that vaccinations cause ASD. n

What factors are predictors of individual's risk for PTSD?
Greater personal injuries and losses, greater intensity of exposure to the traumatic event, and more exposure to the grotesque aftermath of the event. Another predictor of vulnerability for PTSD is the intensity of one's reaction at the time of the traumatic event. Individuals who have especially intense emotional reactions during or immediately after the traumatic event go onto show elevated vulnerability to PTSD. Vulnerability is greatest among people whose reactions are so intense that they report dissociative experiences (a sense that things are not real, that time is stretching out, that one is watching in oneself in a movie)
How can communities and social support have health benefits?
Having connections with your community also seems to provide health benefits. One study found that Canadians who perceive a strong sense of connection to their community were more likely to report having both good physical and mental health. This study adds to the growing evidence that social relationships and bonds can be good for your health. The effect of some types of social support has also been found to be a function of culture, with individuals from cultures emphasizing community and interdependence benefitting more from emotional social support than those from cultures where independence is emphasized.
How can alcohol and drug use affect health?
Heavy consumption of alcohol clearly increases one's risk for a host of diseases. Recreational drug use is another common health imparing habit. Unlike smoking, poor eating habits, and inactivity, drugs can kill directly and immediately when they are taken in an overdose or when they impair the user enough to cause an accident. In the long run, recreational drugs and also elevate one's risk for infectious diseases, respiratory, pulmonary, and cardiovascular diseases.
What is maladaptive behaviour?
In many cases, people are judged to have a psychological disorder because their every day adaptive behaviour is impaired. This is the key criterion in the diagnosis of substance-use disorders. In itself, alcohol or drug use is not terribly unusual or deviant. However, when the use of cocaine, for instance, begins to interfere with the persons social or occupational functioning, a substance use disorder exists. In such cases, it is the maladaptive quality of the behaviour that makes it disordered.
Are there any genetic factors that play a role in the development of schizophrenic disorders?
In twin studies, concordance rates average around 48% for identical twins, in comparison with about 17% for fraternal twins.

How can conditioning and learning have a role in anxiety?
Many anxiety responses may be acquired through classical conditioning and maintained through operant conditioning. An original neutral stimulus may be paired with a frightening event so that it becomes a conditioned stimulus eliciting anxiety. Once fear is acquired through classical conditioning, the person may start avoiding the anxiety producing stimulus. The avoidance response is negatively reinforced because it is followed by a reduction in anxiety. This process involves operant conditioning. Studies find that a substantial portion of people suffering from phobias can identify a traumatic conditioning experience that probably contributed to their anxiety disorder.
What are critiques with the DSM-5 test?
Many critics have question the fundamental axiom that the diagnostic system is built on: the assumption that people can reliably be placed and discontinuous diagnostic categories. These critics note that there is enormous overlap among various disorders symptoms, making the boundaries between diagnosis much fuzzier than would be ideal. Critics also pointed out that people often qualify for more than one diagnosis. Another area of concern is the exponential growth of diagnoses. The number of specific diagnoses in the DSM increased from 128 and the first edition to 541 in the current edition. Some of this growth was due to splitting existing disorders into narrower subtypes, but much of it was due to adding entirely new disorders. For example, DSM-5 includes diagnoses for caffeine intoxication, tobacco use disorder, binge eating disorder, and gambling disorder.

Are equivalent disorders found around the world?
Most investigators agree that the principal categories of serious psychological disturbance--schizophrenia, depression, and bipolar illness--are identifiable in all cultures. Most behaviours that are regarded as clearly abnormal in Western countries are also viewed as abnormal in other countries. People who are delusional, hallucinatory, disoriented, or incoherent are thought to be disturbed in all societies, although there are cultural disparities in exactly what is considered delusional or hallucinatory. Cultural variations are most apparent in the recognition of less severe forms of psychological disorders. Syndromes such as the generalized anxiety disorder, hypochondria, and narcissistic personality disorder are viewed in some cultures as run-of-the-mill difficulties and peculiarities rather than full fledged disorders.
What is the difference between positive and negative schizophrenic symptoms?
Negative symptoms involve behavioural deficits, such as flattened emotions, social withdrawal, apathy, impaired attention, poor grooming, lack of persistence at work or school, and poverty of speech. Positive symptoms involve behavioural excesses or peculiarities, such as hallucinations, delusions, incoherent thought, agitation, bizarre behaviour, and wild flight of ideas. Most patients exhibit booth type of symptoms, but vary in degrees to which positive or negative symptoms dominate. Predominance of negative symptoms is associated with less effective social functioning, and poor overall treatment outcomes.

What biological factors play a role in disorders?
Neurotransmitters are chemicals that carry signals from one neuron to another. Therapeutic drugs that reduce excessive anxiety alter neurotransmitter activity at synapses that release a neurotransmitter called GABA. This finding and other lines of evidence suggests that disturbances in the neural circuits using GABA may play a role in some types of anxiety disorders. Abnormalities of neural circuits using serotonin have been implicated in obsessive compulsive disorders.

People who tend to: A) Misinterpret harmless situations as threatening. B) Focus excessive attention on perceived threats. C) Selectively recall information that seems threatening.
Although stress and illness have been correlated, what is a 3rd variable that could cause illnesses?
Perhaps some aspects of personality. For instance, some evidence suggests that neuroticism may make people overly prone to interpret events as stressful and overly prone to interpret unpleasant sensations as symptoms of illness, thus inflating the correlation between stress and illness.

Profound feelings of guilt and self-deprecation lie at the core of depression in the western cultures, but are far less central to depression in many other societies. In non-western cultures, depression tends to be expressed in terms of somatic symptoms, such as complaints of fatigue, headaches, and backaches, more than psychological symptoms, such as dejection and low self-esteem. These differences probably occur because people learn to express symptoms of psychological distress in ways that are acceptable in their cultures.

How can a lack of exercise affect health?
Regular exercise reduces the risk of many health problems, including some types of cancer, obesity, high blood pressure, and several types of psychopathology. It is associated with increased longevity. Regular exercise also reduces the risk associated with diabetes. For many people with this condition, exercise can be almost as effective as medication. Recent data in Canada shows that only 17% of men and 14% of women currently achieve the suggested time of physical activity a week. A big cause of this decline in physical activity is the increase in the amount of time in sedentary activities, such as sitting in front of the TV, phones, and computer screens. Sedentary activities put people at an increased risk for obesity and have been found to be linked to deceased cognitive and social development. A recent report released said that kids are spending up to eight hours in front of the screen on a typical day.

A substantial majority of people with dissociative identity disorder report a childhood history of rejection from parents and a physical and sexual abuse.
How do cognitive factors correlate with mood disorders?
Some research proposes that depression is caused by learned helplessness--passive giving up behaviour produced by exposure to unavoidable aversive events. Seligman states that the roots of depression lie in how people explain their setbacks and other negative events they experience. People who exhibit a pessimistic explanatory style are specially vulnerable to depression. These people tend to attribute their setbacks to their personal flaws instead of the situational factors. They tend to draw global, far-reaching conclusions about their personal inadequacies based on these setbacks. It was also discovered that depressed people who contemplate and think about their depression remain depressed longer than those who try to distract themselves. These people think constantly about how sad, lethargic, and on motivated they are. Excessive contemplation tends to foster and amplify episodes of depression by increasing negative thinking, impairing problem-solving, and undermining social support. Women have a greater tendency to do this than men.
In light of the findings on Asian Americans an Asian Canadians and mental health, would it be reasonable to infer that psychological disorders are culturally variable phenomena?
Some social scientists embrace a relativistic view of psychological disorders, where as others subscribe to universal or a pancultural view. Theorists who embrace the relativistic view argue that the criteria for mental illness vary greatly across cultures and that there are no universal standards of normality and abnormality. According to them, the DSM diagnostic system reflects an ethnocentric, Western, white, urban, middle and upper-class cultural orientation that has limited relevance and other cultural contexts. In contrast, those who believe in the pancultural view argue that the criteria of mental illness are much the same around the world and that basic standards of normality an abnormality are universal across cultures. These theorists typically maintain that western diagnostic concepts have validity and utility and other cultural contexts.
What are cultural differences revolving around mental illness?

The degree to which a relative of a schizophrenic patient displays highly critical or emotionally over involved attitudes towards the patient. Studies show that a family's expressed emotion is a good predictor of the course of a schizophrenic patient's illness. After release from the hospital, people with schizophrenia who returned to a family high in expressed emotion show relapse rates about three times that of patients returned to a family low in expressed emotion. Part of the problem for patients returning to homes high in expressed emotion is that their families are probably more sources of stress than social support.
Are there any neurochemical factors to schizophrenia?
The dopamine hypothesis asserts that excess dopamine activity is the neural chemical basis for schizophrenia. This hypothesis makes sense because most of the drugs that are useful in the treatment of schizophrenia are known to dampen dopamine activity in the brain.

What is the concept of preparedness in terms of phobias?
The tendency to develop phobias of certain types of objects and situations may be explained by the concept of preparedness. It is suggested that people are biologically prepared by their evolutionary history to acquire some fears much more easily than others. This explains why people develop phobias of ancient sources of threat such a snakes and spiders, much more readily than modern sources of threat like electrical outlets are hot irons. Phobic stimuli associated with evolutionary threats tend to produce more rapid conditioning of fears and stronger fear responses.
