Not being able to think clearly, act normally in social
situations, or tell the difference between what is real and not real are a few
things that make up schizophrenia. There is no specific cause to this mental
disorder many doctors believe that genes may play a role for developing
schizophrenia. Schizophrenia usually beings in men and women's' teen years or
young adulthood, but there is a possibility for childhood-onset schizophrenia
to being after age 5. For a child to be diagnosed with schizophrenia is rare
and it can make it difficult to tell a difference from other developmental
problems the child might have like autism. Hallucinations, lack of emotions,
and delusions are a few symptoms of schizophrenia which develop over the course
of the years; because there is not a medical exam to help diagnose this mental
disorder, psychiatrist should make the diagnosis based on an interview.
Antipsychotic drugs are available for the treatment of schizophrenia and may be the most effective. Living with
this mental disorder seems to be difficult because of the symptoms such as
delusions, because one will not tell apart between real and not real. If being
alone and not being able to tell the difference that could put ones' live in
danger. Also not having a medical test to diagnose schizophrenia, worries one because even though it is rare
children are diagnosed with this mental disorder; and it can be confused with
other developmental problems. The child might be treated with medication that
is not appropriate and the side effects can be very hurtful.

Bipolar
Going back and forth between periods of good or very
irritable moods and depression very quick is a condition known as bipolar
disorder. The specific cause of this disorder is unknown, but it most
frequently occurs in relatives of people with bipolar disorder. Both women and
men are equally affected and the ages it starts are between 15-25. There are
three types of bipolar disorder which are type I, type II, and cyclothymia. Aside
from the quick mood swings and depression, other symptoms of bipolar disorder
may include increased energy, lack of self control, little need for sleep, or
thoughts of suicide. Those are not the only symptoms, but just a few of the
many that characterize this disorder. In order to diagnose bipolar disorder, a
doctor may ask about family history, run laboratory tests, or watch the
behavior of the patient. Mood stabilizers, drugs commonly used, are the first
treatment used. Other drugs that can be used are anti-psychotic, anti-anxiety,
antiseziure, or antidepressant medications. If the patient does not respond to
medication there are other options like Transcranial magnetic stimulations (TMS) and Electroconvulsive
therapy (ECT). The treatment used for the patient with bipolar disorder is to
prevent suicide, avoid hospital stay and moving from one phase to another, make
episodes less frequent and severe, and help the patient function as well as
possible. Living with this disorder must not be easy especially with the episodes
of mania and depression one suffers. A normal life without drugs is out of the
question for someone with bipolar disorder because of the danger some put their
life in. Also there not being a clear cause for this disorder makes it even a
little more scarier, because there can be many factors that trigger this
disorder.

Stress
Stress...stress...stress! That is what us college students experience
throughout the semesters. Not only is school stressful but relationships, work,
driving in bad traffic, family problems, ect. Overwhelmed with the pressures
that are placed on us and coping may seem difficult at times. Challenges or
threats to our lives are what we call stress. Stress is not always a negative
thing in our lives but it can be positive and motivate us to achieve our goals.
Though if it interferes with both one's physical and mental health it is no
good and something needs to be done. Stress provokes for heart rate to rise,
breathing to become more rapid, do not sleep, blood pressure rises, and immune
system goes down. Every situation we face in life is different and the way we
confront them as well. It mostly depends on the resources we have available and
how we choose to deal with the situation; if our resources seem to be enough
then it won't produce stress, but if they are not enough then it produces
stress in our lives. It is also the way we see that stressful situation is an
important factor that impacts both mental and physical health. We decide how to interpret every situation and
whether it will be harmful to us. Effects of stress can be shown through our
body, behavior, and our thoughts and feelings. Stress can be treated by any of these methods
which are medication, self-help, and self management. Exercise, breathing,
relaxation techniques, or a good diet can be some self-help methods to help
cope with the stressful situations we have to deal in life. Stress seems to
never end and it is not only college students dealing with it but everybody out
there. Though certain situations seem to be out of our hands and cause stress,
we can always turn it to be positive and learn from it.
Sleep
Insomnia
Characterized by difficulty of falling or staying asleep is
a sleep disorder known as insomnia. Feeling tired upon waking, difficulty
falling asleep, waking up too early in the morning, and waking up often during
the night and not being able to go back to sleep are symptoms that people with
insomnia have. There are two types of insomnia which are primary insomnia and
secondary insomnia. Primary insomnia is when a person is having problems with
sleep that are not associated with any health problem or condition. Secondary
insomnia is when an individual is having problems with sleep because of a
certain health problem or condition such as asthma or a substance like alcohol
that they may be using. There is also a variation of how long insomnia can last
and how often it occurs in an individual. Insomnia can be acute which is
short-term or chronic which lasts a long time. Acute insomnia can be caused by
emotional discomfort, significant life stress (e.g. divorce), environmental
factors (e.g. noise or light), or illness. Causes of chronic insomnia may be
due to chronic stress, pain or discomfort at night, depression, or anxiety.
Treatment for acute insomnia is not required; but if insomnia makes it hard to
function, your doctor may prescribe sleeping pills. For the treatment of
chronic insomnia the causes are determined and sometimes behavioral therapy may
be suggested. Getting enough sleep at night is crucial for many individuals to
be able to function properly and being deprived from it can bring many
consequences. Though we may all at once experience insomnia at least once in
our lives it must be hard to suffer from it all the time and have to take
sleeping pills. Sleep is so important for humans that it should not be taken
for granted.

Sex
Gender Identity Disorder
Being a female or male helps an individual with their personality
and sense of self. Though gender identity disorder is a condition in which
either a male or female identifies strongly with the opposite sex. The people
that suffer from this disorder often feel uncomfortable with their gender and
act as the opposite sex. The person's behavior and dress are impacted by this
disorder and their self image is affected as well. Those who change their
physical appearance through cosmetic surgery and hormones are most commonly
known as transsexuals. The cause for gender identity disorder remains unknown
but there are theories that try to explain it. Theories suggests that this disorder can be caused by
genetic abnormalities, defects in human bonding, hormone imbalances, or a
combination of several of these factors. This disorder is mostly recognized
before people reach adolescence and it is more common in males than in females.
Symptoms of gender identity disorder include disgust of their own genitals,
withdrawal from social interaction, desire to become the opposite sex, dressing
and behaving like the opposite sex, ect. Counseling is usually recommended to
treat the individual with gender identity disorder as well as their family. The
focuses of counseling are to treat the problems that are associated with this
disorder which are depression and anxiety. Improving self-esteem is also
another focus that counseling targets to help the individual. If an individual
does not receive any type of therapy it can cause social isolation, emotional
distress, and poor self-image. Which will cause the individual to no function
to his/her ability and lead to problems in school or work. Not being able to
identify one's self with the gender we have and wanting to be the opposite sex
has become more accepting in society; but there are still people who do not
accept individuals with this disorder which causes many to commit suicide. Many
who suffer from this and do not have the support behind them take the easy way
out. It is important for us to help those with gender identity disorder, because children are also diagnosed and them being so young do not know how to cope with the stress behind it.

Endorphins
As
known as neurotransmitters, endorphins are among the brain chemicals
that function to transmit electrical signals within the nervous system.
These can be found in the pituitary gland, as well as other parts of the brain,
or are distributed throughout the nervous system. There are at least twenty
types of endorphins that have been demonstrated in humans. Both pain and stress
are the most common factors to the release of endorphins; which interact with
the opiate receptors in the brain to reduce the perception of pain and act like
a drug, such as morphine. However on the contrary to morphine, the activation
of the opiate receptors by the body's endorphins does not lead for dependence
or addiction. Endorphins do not only decrease the feelings of pain but also
lead to release of sex hormones, feelings of euphoria, and modulation of
appetite. Being able to feel fewer negative effects of stress and pain is due
to the high levels of endorphins. The release of these varies among every
individual and no two people produce the same level of endorphins. Food can
play a role on the secretion of endorphins in people. Activities such as
meditation, exercise, massage therapy, and sex can trigger the levels of
endorphins. Though endorphins minimize the pain or stress we feel it can also
be responsible for certain forms of mental illnesses such as OCD. Clinical depression
an sudden shifts in emotions are linked to problems with endorphin production
or the binding process of these. Gathering this information about endorphins
and what they do has put a much more importance on them because they help us in
our everyday lives. If it was not for these the pain and stress would be unbearable.

Korsakoff's Syndrome
Brain damage caused by severe thiamine deficiency occurs
mostly in chronic alcoholics is Korsakoff's syndrome. The lack of vitamins due
to a diet of nothing but alcoholic beverages for a long period of time causes
the deficiency of thiamine which affects the brain and nervous system. Thiamine
is needed by the brain to metabolize its primary fuel, glucose. The loss or shrinkage
of neurons is lead by the prolonged deficiency of thiamine throughout the
brain. Korsakoff's syndrome may follow Wernicke's encephalopathy if it is
untreated or not treated soon enough. Brain
damage occurs, and the doromedial thalamus is an area which is the most
affected. The dorsomedial thalamus is the main source of input to the prefrontal
cortex; resulting in severe short-term memory loss though many other abilities
may remain intact. Memory loss, apathy, and confusion may be symptoms of
Korsakoff's syndrome which are very similar to those people with prefrontal
cortex damage. Korsakoff's syndrome main symptom is memory loss particularly of
events arising after the onset of a condition, or sometimes memories of the
more distant past can also be affected. Confabulation is a distinctive symptom
of this syndrome in which patients invent events to fill the gaps in memory. Patients
mainly confabulate on questions about episodic memory and seldom on semantic
questions. Strategies for studying are product of a fascinating influence of
the tendency for a person to confabulate. Reading the list over and over is an
effective way to learn much better for patients with Korsakoff's syndrome.

Broca's Aphasia
Aphasia is an impairment of language which affects the
production or comprehension of speech and the ability to read and write. This
is due to injury to the brain most commonly from a stroke; but brain injuries
resulting in aphasia may also arise from head trauma, brain tumors, or
infections. Communication with a patient who has aphasia can be severe making
it impossible or very mild. Aphasia can affect mainly a single aspect of
language use, such as the ability to put words together, the ability to read,
or the ability to retrieve names of objects; but commonly multiple aspects of
communication are impaired. Though some channels remain accessible for a
limited exchange of information. It is up to a professional to determine the
amount of function available in each of the channels for the comprehension of
language and to assess the possibility that a treatment might enhance the use
of channels that are available to the patient. Broca's aphasia or also referred
to nonfluent aphasia is one of the most common varieties of aphasia. In this
particular form, speech output is severely reduced and is limited mainly to
short utterances of less than four words. The access to vocabulary is limited and
the formation of sounds is often clumsy and laborious. A person with Broca's
aphasia may understand speech relatively well and be able to read but be
limited in writing. It must very difficult for a person who did not have no
trouble at all understanding a simple sentence to it becoming complicated after
suffering from a stroke that caused Broca's aphasia. Not being able to express
ourselves through language by speaking or writing can be terrifying because how
is it that one can communicate with the world if it seems impossible.

Fetal Alcohol Syndrome
Mothers who drink while pregnant cause their babies to be
born with fetal alcohol syndrome. Facial
abnormalities, hyperactivity, varying degrees of mental retardation,
impulsiveness, motor problems, difficulty maintain attention, and heart defects
are some of the symptoms babies might have. Fetal alcohol syndrome is not only
caused by alcohol consumed during pregnancy but also being exposed to prenatal
alcohol show impairments in language, memory attention, and learning. When a
pregnant woman drinks alcohol it easily passes across the placenta to the fetus
which harms the baby's development by altering the migration pattern of small
neurons. The release of glutamate, the brain's main excitatory transmitter, is
suppressed by alcohol and enhances activity of GABA, the main inhibitory
transmitter; because of this many neurons receive less excitation and
neurotrophina than normal and they undergo apoptosis. During pregnancy there is no safe level of
alcohol consumption for women. If a woman consumes large amounts of alcohol the
problems increase tremendously, especially if alcohol is consumed during the
first three months of pregnancy because alcohol appears to be more harmful
then. In order to prevent fetal alcohol syndrome is for women not to drink any
alcohol during their pregnancy. Many complications can be caused to a baby's
development because of the unwise decision of consuming alcohol during
pregnancy. A mother should always have in mind the health of their child when
thinking of drinking just one small glass of wine, because the consequences can
be devastating. If a pregnant woman is dealing with alcoholism they can join an
alcohol abuse rehabilitation program to help them out throughout their
pregnancy.

Addictions
Additions go from gambling to the most common alcohol and
drugs. An addiction interferes with
someone's life because of the compulsive need for the pleasure given. Having an addiction does no
good to one but rather hurts the person and everybody around them. Drugs and
alcohol are amongst the most common addictions and are life threatening; which
makes me wonder why the use of such harmful pleasure to one's life? Though
after reading more about addictions, I came to the understanding that the
pleasure that a certain drug gives decreases and one tends to go do it again in
order to have the same enjoyable experience as before. Also many turn to
addictions to be able to handle stress or any other problems that they may be
encountering. Many times it seems impossible for a person to be able to
overcome an addiction, because of the negative effects afterwards like fatigue
and anxiety. Though addictions cannot be quite explained well of how it
completely takes over a person's life, it is certain that the brain undergoes
changes that in some ways makes it difficult to be able to quit.

Neurons
An adult brain has approximately 100 billion neurons; all varying
in shape, function, and size. Neurons are specialized to transmit information throughout
the body which makes them the basic building block of the nervous system. A
neuron's contribution to the nervous system is determined by the connections it
has with other neurons; two types of neurons are motor and sensory neuron. The
structure of a neuron depends greatly on the size of the neuron. For example a
small neuron will not contain an axon and will lack dendrites. As for a large
neuron will be composed of a cell body, presynaptic terminals, axon, and
dendrites. Both vary in what they are composed off because of their size. It is
incredible of all the work that neurons take care off in our bodies.

Animal Research
The use of animals is research sounds and maybe cruel, but
the knowledge gained afterwards about a certain issue can be very rewarding. These four reasons can summarize why the need for animal research: legal or
ethical restrictions prevent certain kinds of research on humans, the
underlying mechanisms of behavior are similar across species and sometimes
easier to study in a nonhuman species, what we learn about animals sheds light
on human evolution, and we are interested in animals for their own sake. The
use of animals in research to learn how the brain functions is many times an
ethical debate between abolitionists and animal researchers. Though committees
like the Institutional Animal Care and Use Committee make sure to minimize pain
and discomfort in specific procedures for animals. Animals used for research
are cared for and put in as little distress as possible with all the laws and
regulations countries set for research to be done. With this research can be
conducted and there is medical advances which can help save many lives. I
cannot quite understand why people against animal use in research react so
violently towards researchers. All they are doing is helping to improve the lives of
many others.
