The purpose of this essay is to discuss abnormality
and the influences of heredity and environment on two psychological disorders
which are Autism and Depression, Autism is a lifelong developmental
disability that affects how people perceive with the world and interacts with
others or how person communicates and relates to other people, and how they
experience the world around them. It can also be a complex disorder of brain
development. These disorders are characterized, in varying degrees, by
difficulties in social interaction, verbal and nonverbal communication and
repetitive behaviour. But depression is a disorder that characterised by low
mood and a wide range of other possible symptoms which will vary from person to
person, this illness can develop quickly or gradually and be brought on by life
events or changes in body chemistry, it can strike anyone, and is manageable in
vary many cases.

Abnormality can also defined as
deviation from the norms or a person that is unable to cope with the demand of
every life or perform the behaviours necessary for day-to-day activity, or an
experience in life or development of behaviour patterns that are considered
harmful for the individual; this may be behaviours that we learned from the
environment which is nurture.

The methods used for the classification
of autism and depression are DSM V and ICD mental diagnostician is an
international standard diagnostic classification for all general
epidemiological and many health management purposes and it consists of 10 main
groups including symptomatic, mental disorders. DSM-IV The classification
system of the American psychiatric Association (APA), the diagnostic and
statistical manual of mental disorders (DSM-IV), consists of five axes of
disorders. The diagnostician suggested not to focus only on one clinical
disorder but to consider other important aspects.  

 Autism diagnosing in a person with an
intellectual disability is more difficult, as some of the criteria for autism
can be present in a person with an intellectual disability, mental delay may
mask the autism an a diagnosis may come later or not at all. {In the 1950’s and
1960’s there was speculation that parents may contribute to the condition,
research suggest that injury or dysfunction of the central nervous system may
result in autism, moreover if the individual display a number of this
behaviours on the assessment, then it is likely that they will have some degree
of autistic spectrum disorder.

Furthermore, the DSM-V-
committee has recently published diagnostic criteria for autism spectrum disorder,
their believe is that by examine DSM has over looked a number of important
issues, including social imagination, the diagnosis in infancy and adulthood have
possibility that girls and abdomen with autism may continue to go unrecognised
or misdiagnosed under new manual. In addition, there is a conclude that a
number of changes need to be made in order that the DSM-V- criteria might be
used reliably.  

 Depression: There are different type of
depression symptoms that reliably occur together to form a type of mental disorders.
This allows psychiatrists doctors and psychologists to easily indentify groups
of similar patients. A diagnosis can be made, and a suitable treatment can be
developed and administered to all those showing similar symptoms.

The diagnostic and statistical
manual of mental disorders (DSM) defines abnormality as a clinically
significant syndrome associated with distress, increase in the risk of pain or
death and the loss of functioning, The DMS is manual with over 200 specific
diagnostic categories for mental disorder.           

However, one of the largest problems
of diagnosing in patients is whether or not the diagnosing is valid or
reliable. The test –retest reliability is concerned with whether the same
patient will receive the same diagnosis if assessed more than once by the time
the literature review examining evidence relating to the reliability of
diagnosis of depression, they found that  there are many symptoms of depression which
include low-mood, feelings of hopelessness, low self-esteem, lethargy and sleep
problems, initial diagnosis of depression will help you to assess whether you
could be depressed, the DSM-IV and ICD-10 are both operational diagnostic system,
In conclusion there will always be issues of validity and reliability in
diagnosis, certain groups of people will be more likely to receive a diagnosis
to a disorder compared to others and psychiatrists will need to be careful when
diagnosing patients.

Mental health disorders, this
can be defined as a state of well-being in which every individual realizes his
or her own potential, can cope with the normal stresses of life, can work
productively and fruitfully, and is able to make a contribution to his or her
community. Mental health disorder can cover a broad range of disorders, but I
will only discuss Autism and Depression, but the common characteristic is that
they all affect the affected person’s personality, thought processes or social
interactions. They can be difficult to clearly diagnose, unlike physical
illnesses, According to data from SAMHSA, 20 percent of people in America
surfer from a form of mental disorder, and 5 percent surfer from a disorder
severe enough to affect school, work or other aspect of life.
