The Influence Of Phenylketonuria On The Environment

Burger (2008), says that there are many theories of personality and psychologists try to explain it with their own approaches. Discussed here will be the psychoanalytic approach, the trait approach, the biological approach the humanistic approach, the behavioural/social learning approach and the cognitive approach. They were devised to search for specific patterns in behaviour and ways of thinking about these

Define Phenylketonuria. This is a rare inherited condition where the infant is born without the capability to properly break down phenylalanine. Also known as PKU. This allows the amino acid (phenylalanine) to build up in the infant’s body. Which means that a diet high in protein can lead to multiple serious health problems because of the dangerous levels that can build up from the incapability of breaking down phenylalanine. For someone diagnosed with PKU, it is a lifelong lifestyle change to follow a diet that limits the intake of phenylalanine which found mostly in proteins.

Personality and how we behave have been of much interest to psychologists for a long time now and because of this there have been many theories and theorists that have been developed. Personality is defined as consistent behavior patterns and intrapersonal processes originating within and individual (Fritzley, 2012, p. 10). There are six main approaches to personality psychology they include: biological approach, humanistic approach, behaviorist approach, trait approach, psychoanalytic approach and cognitive approach. Each approach shines a little light onto why we behave the way we do and how our personalities are formed, the approaches contain many different theories from

A person’s personality says much about who he or she is. People define personality in different ways. Researcher after researcher has tried to come up with the best definition for what personality truly means. Case studies, correlational studies, and experimental designs are some of the most commonly used methods of research. These methods help better define personality. The advantages and disadvantages of each method differ and can be helpful or hurtful to the research of an individual’s personality.

Large neutral amino acid supplements can be consumed; they block phenylalanine from entering the brain. They can also lower the plasma phenylalanine levels. However, it has been suggested that taking large neutral amino acid supplements has no effect on those who maintain a phenylalanine restricted diet. Sapropterin is another supplement that can be used to lower phenylalanine levels. A study found that those taking 10mg/kg/day of sapropterin had a 30% reduction of plasma phenylalanine levels; of those 30%, 10% of the people had phenylalanine levels higher than 1200 µmol/L. There is also an alternative enzyme therapy under investigation for patients with PKU. This enzyme is an injectable form of phenylalanine ammonium lyase, also known as PegPAL, which is supposed to substitute phenylalanine hydroxylase. This pharmacologic treatment is being investigated for those who do not respond to the treatment of

in order to analyze the patterns that determine personality, certain issues need to be addressed

As we grow in life we develop our own unique personality. I believe our personality is developed through what we learn, and the values we're brought up with. One example of a value would be our parents telling us it's not nice to lie. We also develop our personality through our environment and the relationships with others. Our peers and the people we associate often have a big impact on how we develop our personality. Drives, such as the drive to become a better individual also impacts our personality. We

In an attempt to understand the human psyche as it relates to personality, theorists such as Sigmund Freud, Carl G. Jung, and Alfred Adler all developed their theories to describe personality. To better understand the mentioned theorist’s beliefs it is necessary to compare and contrast the various psychoanalytic theories characteristics as well as to make mention of the portions that are agreeable or disagreeable. Also, the stages of Sigmund Freud's theory and Freudian defense mechanisms will be conversed.

The environment of the fetus is critical to proper development. Adverse factors experienced in the fetal environment interfere with early development. Genes respond to their environment. The adverse factors can essentially rewrite the genetic make up of the infant and alter the expression of the gene (Watters, 2006).

who suffer from PKU, phenylalanine can’t be converted in tyrosine, like in normal persons. If

Phenylketonuria, otherwise known as PKU, is a rare genetic disease that is caused by a person’s body being unable to metabolize the amino acid phenylalanine. The disease can cause mental retardation because the build up of phenylalanine in the body. When phenylalanine is not broken down and turned in a different amino acid, tyrosine, it can create other enzyme routes that build up in the blood stream and body tissue. This can be extremely harmful to the body and its development. This disease is caused by missing the enzyme phenylalanine hydroxylase, this enzyme is the one that normally breaks down phenylalanine. It is rare for this enzyme to be completely absence, but this form leads to the most severe mental

In the article “Our Personality- Is it Genetically Inherited or Determined by The Environmental Factors” written by Alexandra Lupu, she demonstrates three possible process that is done to form one’s personality and argues that she believes individual’s personality is formed uniquely with environment inheritage interacting with each other. After stating her argument, Lupu explains the three types of approaches that divides the psychologist that determines one’s personality. First, nomothetic approaches, which is believed that one’s personality is constant and it is minimally influenced by external factors. Second, Idiographic approaches, which is similar to Lupu’s argument that both factors takes a big role in personality and finally, the complementary

While psychology theorists vary greatly on their theories of personality, they all concur that numerous elements go into the creation and development of personality. The elements used in the creation and development of personality are: nature versus nature, the unconscious, view of self, development, motivation and maturation. Each of these elements contributes to the understanding of personality theory. To better understand the connection of these elements and the formation of personality theory researchers have conducted cases studies, surveys, and laboratory observations in order to observe the relationship between these elements and personality. Based upon the research that has been conducted correlations and casualty can be formed

The more you understand about personality, the better able you are to judge what motivates people - and yourself.

The enzyme metabolizes the phenylalanine into tyrosine. Phenylalanine is a type of teratogen (Any organism that can cause birth defects0. If there is a lack of PAH there is a buildup of phenylalanine, which is toxic to the nervous system cells, and can cause abnormalities in brain structure and bodily function. This is toxic to the nervous cells because the high PAH levels can produce abnormal nerve cells with abnormal axons and dendrites, and cause structural repercussions in the myelin sheath (hypomyelination and demylenation). These abnormal forms can cause the nerve cells to interrupt cell communication, and halt nerve impulses. It has been also found that high levels of PAH can cause damage to the white matter presiding in the brain. Not only does PKU effect the creation of PAH but it also effects the production of neurotransmitters in the brain called dopamine. This is made from tyrosine and when in low amounts cannot make a sufficient amount of dopamine. If a patient with PKU is to have low levels of dopamine it can cause mental retardation. It has also been found the patients who receive sufficient amounts of tyrosine through diet, can still retain learning
