Topic 12: Eating Disorders

What are eating disorders?
Eating disorders can be seen as many different things by many different people. The main thought is that eating disorders such as anorexia are simply attention seeking devices. However, according to the Eating disorders foundation of Victoria, they are a “dangerous mental illness…which often requires psychological and/or physical intervention to promote recovery.”
There are various different eating disorders, and, unlike normally thought, not all of them result in “skinniness”. The most well known eating disorder is anorexia, which is simply not eating. Some other eating disorders are binge eating, bulimia and compulsive overeating.
What are the causes of eating disorders?
These illnesses can be caused by many different things, but the main reason has to do with the mental state of the victim. Low self-esteem, depression, perfectionism and feeling inadequate can all contribute to the development of an eating disorder.
As well as these psychological factors, it has been reported that there may be biological influences on this topic. One theory is that there is a chemical in the brain which causes disorders such as these.
Nature or Nurture?
The nurture side of this argument is pretty straight forward. It states that people who develop eating disorders such as anorexia develop them because they are raised to think that this behavior is acceptable in society. Some of the causes of this issue, such as feeling inadequate and low self-esteem, can be a result of the pressure on them to look such a way. This message is usually sent through the media, and some people argue that it is therefore the way that this society allows the media to “nurture” our people that result in some of them establish eating disorders.
It has been stated that people who have family members such as parents or siblings who have or had an eating disorder are at more risk of developing one them self. This can be seen as proof both from nurture and a nature side. The nature side would argue that this is because the mother has the genes for this disorder to occur for the child. In the year 2000, researches stated that they had “found a gene for anorexia”. This is major evidence that could be used for the nature side of this great debate, but is yet to be confirmed.

Questions:
1) What would be the nurture side of the argument for the statement “It has been stated that people who have family members such as parents or siblings who have or had an eating disorder are at more risk of developing one them self.”?
2) What is your view on this topic?

P.S . This is a quote that I found while searching information “We’re dealt a hand, taught certain rules about how to play it, then take those rules on the road and implement them.” This suggests that it is both Nature and Nurture that have an influence on our lives.

Topic 11: OCD

According to the Arnot Ogden Medical Glossary(2009), Obsessive-Compulsive Disorder is “an anxiety disorder in which a person has an unreasonable thought, fear, or worry that he or she tries to manage through a ritualized activity to reduce the anxiety.”

Obsessive-Compulsive (OCD) is a mental illness in which the sufferer experiences exaggeration of the normal human behaviour of anxiety. Anxiety is normal, and is part of ‘being human’. It’s just worrying about everything in an exaggerated way. For example, many sufferers of OCD will repeatedly go back and check they’ve turned something off (lights, oven, etc) ‘just to make sure’. One of the most common instances of OCD is the need for constant hygiene, which often causes the sufferer to be continuously washing their hands.

In terms of the Nature-Nurture debate , OCD is seen as a disorder that derives from both sides of the argument, however it is important to see what role both nature and nurture play.

The main role of nature in the concept of OCD is similar to the role nature plays in many other arguments. From a nature perspective, many sufferers are seen to be born with the predisposition to OCD, and may even have it all of their life. This can be especially common if one or both parents have the disorder, as in the case of many disorders.

But one must remember that even if a person genetically inherits traits such as
these, they only have the predisposition to the disorder. Something has to happen to set off these predispositions, and this is where the nurture argument comes in. People often develop OCD after an experience they had which has affected them. For instance, a rape victim may feel ‘dirty’, and so they wash and wash their hands all the time, to help them feel ‘clean’ again.

OCD can definitely be seen as being brought on by factors of both nature and nurture, however it is important to see what role each plays in one acquiring the disorder. This disorder may be a combination of both, however both nature and nurture play important parts.

Questions
Do you believe that OCD is either nature or nurture, or both?
Could OCD be a genetic trait amongst families?
If you were a professional, would nature vs nurture be an important factor to look at in the treatment of OCD?

Topic 10: Schizophrenia


Schizophrenia




Schizophrenia is a psychiatric diagnosis that impacts upon and distorts all five senses of a person. The patient is said to experience “auditory hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking with significant social or occupational dysfunction.” (Wikipedia)

People with schizophrenia may have perceptions of reality that are strikingly different from the reality seen and shared by others around them. Living in a world distorted by hallucinations and delusions, individuals with schizophrenia may feel frightened, anxious, and confused. (schizophrenia.com)

Many scientists believe that schizophrenia is an inherited disorder, a biological predisposition. Studies have shown that people in a family with a history of mental illness are more likely to develop the disease.

However, recent research is trying to prove that the genes containing the disorder are not dangerous unless triggered by an environmental factor. In Finland, a study on adopted children obtaining schizophrenia was conducted. Children that had a high genetic rate and were adopted into an abusive, dysfunctional family had an 87% higher rate than a similar child brought up in a loving, non-abusive setting. (http://www.schizophrenia.com/hypo.php) Other factors can include stress during pregnancy, social or family distress and unusual environmental circumstance causing anxiety.

From this information and any further information, answer the questions below.
1. Do you believe that schizophrenia’s origin is from Nature or Nurture?
2. What experiment or study would you conduct on this topic?
3. What other environmental factors do you think would have the biggest impact on the rate of schizophrenia?

Topic 9: Aggression

Aggression in psychology can be seen as a behaviour that is intended to cause pain or harm physically or emotionally. From a nurture perspective aggression is decided not by your genes but by the community and role models. According to Bandura children copy their role models, as such it is important to have non-aggressive parents/guardians or other role model figures in their upbringing so as to have a non aggressive personality. Bundura also states that behaviour is learned through rewards, this means that if a child aggressively bullies another child and receives a reward from this behaviour (sweets, or enjoyment), then they will repeat this behaviour in future. The Stanford Prison experiment is another example of how aggression is caused by nurture not nature. In this experiment guards conformed to how they think they should act and became aggressive when normally they weren’t.

How do these experiments support nurture?

What other explanation could there be for the aggression shown in the Bobo doll experiment and the guards in the Stanford Prison experiment?

Topic 9: Multiple Personality Disorder

Multiple Personality Disorder/ Dissociative Identity Disorder

Multiple Personality Disorder, also known as Dissociative Identity Disorder refers to a lack of connection in a person’s thoughts, memories, feelings, actions, and sense of identity. A severe form of dissociation is known to be daydreaming. There are usually two or more personalities that are developed in the course of this mental disorder, each unique with development of its own age, sex, race, postures, gestures, and way of talking. It can be imaginary people or even an animal. These personalities act as a coping mechanism in a violent, traumatic or painful situation that triggers prior traumatic experiences. Through the process of “switching” a personality takes over another. It can take from seconds to days for “switching” to occur. The environmental triggers or requests of therapists under hypnosis can stimulate this process. When a personality is revealed, the behaviour and thought are completely controlled by that particular personality.

Symptoms
The symptoms of multiple personality disorder are following:
• Amnesia
• Depersonalisation – feeling that one’s body is unreal, changing or dissolving.
• Derealization – perceiving the external environment as unreal
• Identity disturbances – two or more distinct, split identities that continuously have power over the person’s behaviour
• Inability to recall key personal information that is too severe to be just “forgetfulness”.
• Highly distinct memory variations
• Other mild symptoms include: depression, mood swings, suicidal tendencies, sleep disorders, alcohol or drug abuse, compulsions and rituals, psychotic-like symptoms, eating disorder, headache, time loss, and “out of body experiences”.

Diagnosis
The diagnosis of dissociative identity disorder may consume a large amount of time and involve complex diagnosis as the symptoms overlap with many other diseases and disorders such as depression, schizophrenia, personality disorder, somatization disorder and panic disorder. Firstly the physical conditions are eliminated through testing for brain disease, side effects of medication and other substances, recent extreme physical fatigue, epilepsy and other seizure disorders. Then through psychotic tests and interviews, specific mental disorder can be identified. Below is a diagnostic criteria list for multiple personality disorder from an article on

Encyclopaedia of Mental Disorders:
• Traumatic stressor: The patient has been exposed to a catastrophic event involving actual or threatened death or injury, or a serious physical threat to him- or herself or others. During exposure to the trauma, the person's emotional response was marked by intense fear, feelings of helplessness, or horror. In general, stressors caused intentionally by human beings (genocide, rape, torture, abuse, etc.) are experienced as more traumatic than accidents, natural disasters, or "acts of God."
• The demonstration of two or more distinct identities or personality states in an individual. Each separate identity must have its own way of thinking about, perceiving, relating to and interacting with the environment and self.
• Two of the identities assume control of the patient's behaviour, one at a time and repeatedly.
• Extended periods of forgetfulness lasting too long to be considered ordinary forgetfulness.
• Determination that the above symptoms are not due to drugs, alcohol or other substances and that they can't be attributed to any other general medical condition. It is also necessary to rule out fantasy play or imaginary friends when considering a diagnosis of DID in a child.
(Encyclopaedia of Mental Disorders, 2009)

Causes
The causes are controversy as to whether it is due to nature or nurture influence. It is commonly believed that during early childhood, a routine of repetitive extreme torture, sexual and/or emotional abuse, or neglect result in a development of separate identities on a young child to cope with the traumatic situations. 98-99% DID patients have experienced recurring, intense and life threatening disturbances at sensitive developmental stage which before the age of nine.

Who are vulnerable?
There is general conformity that the cause of Multiple Personalities is keeping the feeling of childhood sexual abuse inside or any very bad memories. Children who live under a shelter of unwelcome, no warmth or no love are likely to have Multiple Personalities because of the depress memories that they have experienced. These children are often kept in a situation of such extreme terrifying and confusing circumstances. Mostly children that have the terrifying experience they will create a boundary so that the horror doesn’t occurred to them again.

Treatment
To cure a patient with Dissociative Identity Disorder (DID) is that make sure do not use drugs to treat patients. We should:
1. First we should ensure that the patient feel safe and stabilised, before experimenting or exploring their problematic identities.
2. Second some patients are more comfortable of hospitalize, it support and monitoring are supply as throbbing memories are addressed.
3. Third hypnosis may help to find out the identities hiding inside a person. Try to talk through them, make their emotions more stabilised.

Consequently DID can be cured by encouragement by negotiating, arranging the unification of the identities, facilitated with imager and hypnotic suggestion. However psychotherapy is still working on how to actually cure the really hurt patient. Some really light problematic patient can be cured fully as long they stay in a circumstances that they feel safe. Although the patients that have more bad alter inside them, yes they can be cured as well, they are still treatable but need to spend time.

Questions
1. What do you think is the main cause for dissociative identity disorder or multiple personality disorder?
2. How can this be prevented?
3. Do you think multiple personality disorder is the result of nature or nurture? Give reasons.

Topic 8: Bipolar Disorder

What is Bipolar disorder?
Bipolar is a mental illness which effects the functioning of the brain. The patient generally experiences extreme moods – very over excited or extreme depression. In many cases the person may be affected so much that they experience the symptoms of psychosis (Confused thinking, delusions and hallucinations) and are unable to distinguish what is real and what is not.

What causes Bipolar Disorder?
What causes Bipolar disorder has never clearly been understood; however, similar to any illness its causes are said to be a combination of hereditary and other external causes. Yet, it has been stated that depending on the environment the patient is exposed to, can determine whether the illness is triggered. For example, it is recommended that a person with the disorder maintains a regular routine and has a normal sleeping pattern.

Is the Bipolar Disorder Nature or Nurture?
It is difficult to say whether the Bipolar disorder is either entirely nature or nurture. However, it is true that the environment one is exposed to plays a large part in the activation of the illness but then again the illness was obtain through genetics in the first place.

Let’s say that there is a middle aged man who is experiencing a large amount of stress due to a business related issue. He spends most of his time working and not much time doing relaxing activities, such as spending time with the family. This man, who for this example we will call Ted, has a family history of Bipolar Disorder however he has never been tested for the disease because he has never displayed any symptoms. But Ted has not been getting a lot of sleep because of all the stress he has been experiencing. Furthermore he seems to be experiencing extreme moods and has not been himself, but of course he does not notice the change in his behavior because he is virtually living in his own world. Luckily, his family and close friends notice the extreme changes and are able to get Ted help. Ted is prescribed medication and attends support groups for people with Bipolar Disorder. After a long struggle he is nursed back to health and can live a normal life as long as he continues to take the medication and keeps a regular routine.

Ted was lucky that he received help when he did and that was all thanks to his loving family and friends. However, there have been unfortunate cases in which people with the disorder have not received help in time and have gone to extreme lengths. This is mainly because they do not have family who are aware of the problems they are experiencing. Whereas, because Ted was surrounded by people who were aware of his problem and supported him, his recovery was very successful.

On the other hand, it is argued that it was just a coincidence that the most stressful time came at the same time Ted experienced the symptoms of the Bipolar Disorder. It can be argued that the illness was inevitably going to be triggered at that age no matter what environment Ted was exposed to at the time. After all one of the reason for having Bipolar disorder is because it is inherited in the first place.

Topic 7: Drug Addiction

Drug addiction, as we all know, is a condition that arises as a result of frequent use of drugs. Drug-seeking behaviour, slow reaction times, random relapses and a range of mental illnesses are all well-known consequences of drug abuse. Drugs can range from substances such as caffeine to nicotine or illegal drugs such as heroin or cocaine. Some argue drug addiction is the result of genetics, but others say it is due to environmental factors and the influence of parents, peers and role models.

The distinction of the role of genetics in predispositions to drugs such as alcohol has become increasingly blurred as more and more studies are being conducted. Studies have clearly shown that a child exposed to alcohol in their home environment is 3 to 4 times more likely to experience problems later on in life in relation to alcohol abuse. It has also been made evident that the younger a person takes their first drink, the likelihood of these problems occurring dramatically increases. In saying this, it must be said that although genetics play a role in the inclination to abuse alcohol or other drugs, other factors (as mentioned above) certainly influence development of the disease and the behaviours displayed by a person with these risks.

There are three major aspects that contribute to a person’s life in the way of successfully managing addiction or determining propensity to fall into the spiral of addiction. One of these three contributing factors is lifestyle and social choices. If a person never takes a drink, obviously they will not have to face the physical addiction of the illness. If someone has had no exposure to alcohol by choice or by no will of their own, the addiction is pre-emptively prevented. On the opposite end of the spectrum, in homes where drinking holds a significant place in the lifestyle held, it can be much harder to deter addiction.

Children who are raised in an environment of binge drinking, drunkenness or other irresponsible alcohol and drug use in either familial or social surroundings, are more likely to consume alcohol or drugs than those in environments with an absence of these substances. Of course, there are always exceptions but an atmosphere of insufficient alcohol education and a readily available stock of alcohol is apparent, the trends tend to sway in the direction of alcohol abuse more than other environment without these factors.

People are also at a higher risk of succumbing into addiction if there is a family history of alcoholism or drug abuse evident. In cases of alcoholic parents, the development of alcoholism is 3-400% higher than in families without this record, and 200% higher if alcoholism was present in the previous generation. Clearly hereditary influences cannot be controlled, but it is strongly believed among some that if parents can provide good lifestyle choices and a healthy atmosphere, atrocities such as drug addiction can be avoided.

What do you think? Do you believe a healthy lifestyle can change the genetic path of drug addiction? Are there any circumstances you believe that nature rules over nurture in relation to this issue? For example: a baby born to a drug-addicted mother who subsequently is born with a taste for drugs.
