The Causes of Attention Deficit Hyperactivity Disorder

There are many causes of attention deficit hyperactivity disorder. They are brain structure, brain chemicals, nerve pathways, genetic factors, dietary factors, and environmental factors.

Brain Structure And Causes of Attention Deficit Hyperactivity Disorder

Studies using modern imaging methods show there is a variation in the size of some parts of the brain in kids with ADHD when related to kids who do not have ADHD. The regions showing difference are the caudate nucleus and globus pallidus, the prefrontal cortex, and the cerebellum.

Brain Chemicals

Irregular activity of some brain chemicals present in the prefrontal cortex may cause attention deficit hyperactivity disorder. The chemicals such as dopamine and norepinephrine are of very special concern. These chemicals are neurotransmitters, or chemical couriers, that impact both mental and emotional performance. They also have an important role in the “reward response.”

Nerve Pathways

Another region of concern is a network of nerves known as the basal-ganglia thalamocortical nerve tract. Irregularities along this neural path have been linked with causes of attention deficit hyperactivity disorder, Tourette syndrome, and obsessive-compulsive troubles, all of which share some indications.

Genetic Factors

Genetic elements may act as the most significant role in ADHD. The relations of attention deficit hyperactivity disorder children, both boys and girls have much greater level of ADHD, asocial, mood, anxiousness, and substance abuse troubles than the families of non-ADHD kids. A research described that most of the children with a diagnosing of ADHD dealt it with their twin.

About half of adults and most of children with a genetic immunity to thyroid hormone, necessary for normal brain growth, have ADHD. Individual who have this problem seem to have a more serious kind of ADHD. The thyroid trouble is not a usual cause of ADHD. Only people with a family background of thyroid illness are at danger.

Dietary Factors

Infant deficiency disease is a big risky attention deficit disorder symptom. Even if kids get adequate food later on, babies who suffer from poor nutrition may have behavior troubles, the most prevailing being attention-deficit trouble.
Lacks in Zinc and Essential Fatty Acids also cause attention deficit hyperactivity disorder. Various dietary elements have been studies in link with ADHD which also includes sensitivities to some food chemicals, lack of fatty acids (substances that cook up fats and oils) and zinc, and sensitive to sugar.

Environmental Factors

Studies recommend that antenatal vulnerability to alcohol, environmental lead, tobacco, and other poisonous substance may raise the danger for ADHD and behavioral troubles.

The Attention Deficit Disorder without Hyperactivity Symptoms

Individuals with attention deficit disorder without hyperactivity have a range of various experiences. Causes of attention deficit hyperactivity disorder and ADD are same. They may have few or all of the below symptoms to differing level:

Not fit to separate out insignificant sounds like a car driving by an opened window, the noise of a central air unit, or the rubbing of a pen on paper.
Not fit to pay close attention to significant info, such as instructor’s teachings.
Trouble in reaping the exact meaning from talked info.
Difficulty in making out and remembering significant words and sentences.
Trouble in remembering the instructions for a school assignment.
Not fit to concentrate on visual info.
Hypersensitivity to impulse fluorescent brightness and not fit to brush aside insignificant visual info.
Feeling deluged by great amounts of written info in schoolbooks or schoolroom assignments with many instructions or problems to puzzle out.
Tactual defensiveness that is they are extremely sensible to physical aesthesis such as the feel of clothing labels in contact with their skin or a gentle wind blowing their hair. Aesthesis such as these can vary from gently deflecting to annoying.
High degrees of olfactory sensitivity can also be a trouble for few attention deficit disorders without hyperactivity students. They may find aromas that other students do not scent because they cannot separate out or brush aside them. They may find scent deflecting or offensive.

Common Behavioral Symptoms Of Individuals Suffering From Attention Deficit Disorder without Hyperactivity Symptoms

Social accomplishments and conduct troubles may also happen. Students may have trouble with:
Moving freely with other individual. Others lack of attention and impulsivity can impact their ability to abide by rules and routines and react appropriately to compeers and adults who talk to them, making conflicts and misinterpretations.
Significant conduct troubles. Their impulsivity can make mishap, making harm to themselves or others.
Hyperactivity makes these students at greater danger for disciplinary problems in schools. They are more possibly than their compeers to be conditioned, debarred, and kicked out.

Attention deficit disorders without hyperactivity students may run out to follow with instructor requests, finish their work, or may have lower academic functioning.

In Academic, Attention deficit disorders without hyperactivity and ADHD students are at higher risk for poor performance and school run out.

These students also have problem in learning. It is normal for children with Attention deficit disorders without hyperactivity or ADHD to have handwriting failings.

A Guide To Attention Deficit Disorder Signs And Symptoms

Attention deficit disorder is characterized by three major features that include hyperactivity, poor attention skills and deficient impulse control. Any two of these suffice for ADD diagnosis. Frustrating non-presence of mind is the hallmark of attention deficit syndrome, and people suffering with ADD normally have a feeling of restlessness and desperation.

Various Attention Deficit Disorder Signs And Symptoms

A very common attention deficit disorder sign and symptom is the people sudden realization that they have not heard anything they were listening to, remember nothing they were trying to learn, or saw nothing of what they were seeing. They misplace things, miss directions and information, and sometimes struggles to stay abreast of conversations. There is generally a sense of being away from the reality, and disembodied separation from being physically present.

Being absent minded causes short-term attention spans, and distractibility, except around activities of motivation and high interest. And this fosters chaos.

A rare attention deficit disorder sign and symptom is the extraordinary mechanical skill, and person suffering from this disorder is able to disassemble and assemble the complex object and pieces of machinery very quickly and efficiently. Many suffer from coordination difficulties where feet are stepped on, things are dropped, and balls fly in the wrong directions. While asking for direction, the person loses the track after one or two sentences. People suffering from ADD are ashamed to admit their lack of comprehension, and know that asking for clarifications would be futile, so they master the art of showing confidence.

Distraction is another common attention deficit disorder sign and symptom, but is not consistent. For person suffering from ADD, focusing requires much higher level of motivation as compare to other people. ADD is situational, and vary greatly as per the circumstances for the same person. The same person or child may perform extremely well in certain classes, but is disruptive, scattered and unproductive in others.

Another attention deficit disorder sign and symptom is impulsiveness of deed or word, along with badly-controlled emotional reactivity. The person keeps interrupting others and waiting for the turn might feel like a torture. The person suffering from ADD will often speak or act impulsively, and the consequences are negative.

Hyperactivity is another attention deficit disorder sign and symptom, and the person might find it impossible to keep physically still. Some fidgeting might be apparent such as pumping thighs, tapping fingers, chewing nails, biting teeth and so on. There may also be excessive talking for some. Restlessness with long periods of procrastination is also an attention deficit disorder sign and symptom, and promise of reward or threat of failure must be immediate.

Attention deficit disorder symptoms in children are largely similar to those in adults, but it is easier to diagnose, and children suffering from this disorder usually act the part of class clown.

What Is Attention Deficit Disorder?

Attention deficit disorder is actually a condition where the person may have some difficulty focusing his or her attention. This is not done voluntarily and the person with this condition can not help it. There is a difference between attention deficit disorder and attention deficit hyperactivity disorder. Many people used to think that both are the same disorder but recent studies have shown that there are large differences between individual who suffer from attention deficit disorder and the latter disorder. Basically, both disorders have the inattention but the hyperactivity is missing from the attention deficit disorder.

Characteristics Of Attention Deficit Disorder

Individuals with attention deficit disorder tend to be a bit careless when it comes to school work or work details. Other than this, the individual will also manifest signs of being bored or distracted when he or she should be focusing his attention on what is at hand. People with this disorder also have some difficulty organizing his or her things as well as may have some difficulty keeping track of his or her things. The person with attention deficit disorder is also prone to losing things and losing track of daily activities or what is supposed to be in his or her schedule. Following instructions may also be a bit of a hurdle for those with attention deficit disorder since their attention may be elsewhere when the instructions are given out or the individual may not have been listening at all when the instructions were given.

Diagnosis Of Attention Deficit Disorder

The symptoms of attention deficit disorder may seem quite normal for some children or may occur to people at some point in their lives. This actually makes the disorder a bit difficult to diagnose or be brought to the attention of specialists. Not all of the characteristics or symptoms may manifest in some people and in others more symptoms may occur. Although, this disorder is commonly labeled as a childhood disorder, there are also some adults who suffer from this. Attention deficit disorder may be low key in some people and easily recognizable in others. There are adults who have come to manage and control this disorder on their own, especially when the degree of their disorder is easy to control.

Children with attention deficit disorder may be easier to spot or recognize and parents can take steps to manage and control this disorder. Some may even be diagnosed wrongly just by manifesting some of the symptoms and characteristics of attention deficit disorder. Some of the symptoms may be caused by lack of sleep or stress.

The Attention Deficit Hyperactivity Disorder Symptoms

In the fourth edition (DSM-IV) of Diagnostic and Statistical Manual of Mental Health, all the attention deficit hyperactivity disorder symptoms are outlined. All of the attention deficit hyperactivity disorder symptoms of inattention, hyperactivity, and impulsivity must have remained for at the least six months to a level that is dysfunctional and discrepant with the stages of growth in the child. Some of these symptoms are also seen in attention deficit disorder without hyperactivity.

There must be clean proof of substantial disability in social, academic, or occupational performance. And the attention deficit hyperactivity disorder symptoms are not wholly made by another serious physical disorder or mental disorder.

Recognizing Adult Attention Deficit Hyperactivity Disorder

Attention deficit hyperactivity disorder is a condition that generally starts in children but may be retained up to adulthood. Adult attention deficit hyperactivity disorder is not as easy to diagnose compared to that in children because adults may have developed a coping mechanism to make up for their disorder. Due to this so called coping mechanism, adult attention deficit hyperactivity disorder may be misinterpreted as some other condition in adults or as something else.

Adult attention deficit hyperactivity disorder is a behavioral condition that affects not a lot of people, about three to five percent of children in the United States are said to have adult attention deficit hyperactivity disorder and most of these children, if not diagnosed and treated early, may bring this condition up to adulthood. The condition affects boys more often than girls, but the retention up to adulthood is even for both genders.

Symptoms Of ADHD In Adults

Adult attention deficit hyperactivity disorder may manifest differently than the condition in children. Signs and symptoms of adult attention deficit hyperactivity disorder are disorganization of things (both personal and work related), forgetfulness, tardiness, has anger management issues, impulsive behavior, mood swings, defiance with authority, procrastination, difficulty in following instructions, difficulty in concentration and low self esteem.

These attention deficit hyperactivity disorder symptoms may also be accompanied by behavior such as being anti social or withdrawn from other people or crowds. On the other hand, those who suffer from adult attention deficit hyperactivity disorder may also be extremely outgoing and sociable to the extent that they may dislike being on their own and prefer to always have someone with them or be in a crowd. Those with adult attention deficit hyperactivity disorder may also manifest frustration due to not being able to concentrate or be angry with oneself or others whom he or she may perceive as the source of the intrusion on his or her concentration.

Many individuals with adult attention deficit hyperactivity disorder may also indulge in substance abuse or may be smokers and heavy drinkers. They also tend to have more problems with relationships, either from work or in the personal level. It is also wise to look out for signs such as driving violations and low work performance.

Treating Adult Attention Deficit Hyperactivity Disorder

Adult attention deficit hyperactivity disorder can be managed and controlled with a combination of diet and behavioral therapy. Medication may be sued but it is not usually recommended unless the adult attention deficit hyperactivity disorder is destructive to one’s daily life.
