External ADHD Symptoms and Effects
Attention Deficit Hyperactivity Disorder (ADHD) is basically CNS dysfunction (mainly the frontal cortex and the reticular formation of the brain), which is manifested difficulty sustaining attention and concentration, impaired learning and memory, excessive motor activity (hyperactivity) and incontinence (impulsivity). ADHD is common among younger students.
The main ADHD symptom is “violation of attention.” Attention deficits characteristic of all children with this syndrome, and hyperactivity is not always the case. ADHD is divided into two classes: attention deficit disorder and hyperactivity “and attention deficit disorder without hyperactivity.
What causes ADHD:
- Imbalance and disruption of production of neurotransmitters (catecholamine, serotonin, etc.);
- Lack of control and “quenching” behavior in septal hippocampus system (SHS);
- Dysfunction of the frontal lobe of brain.
ADHD is associated with the formation of various substances (flavorings, food additives, excessive consumption of sugar, impaired glucose metabolism, food allergies, lack of magnesium and iron, high content of lead in the body, and others.) ADHD is determined by mutations in three genes that regulate dopamine metabolism.
There are several forms of ADHD with different symptoms:
- Attention deficit disorder without hyperactivity – ADD;
- Combined syndrome with hyperactivity;
- Complicated form (with ADHD symptoms of neurotic variants of the combined version);
- ADHD-H (genetic origin);
- ADHD-0 (organic origin);
- ADHD-OG (mixed origin);
- ADHD-Cr (cryptogenic).
Emotional disturbances are common among ADHD symptoms. In emotional development goes, tend to lag behind that imbalance manifests, temper, intolerance to defeat.
Social and behavioral ADHD symptoms
Social and behavioral aspects of these children are important because of the spreading everywhere negative influence on their peers. In children, there are difficulties in relations with their not only peers but also adults. Interpersonal behavior of children with ADHD is often characterized by impulsiveness, excessiveness, persistence, disorganization, impressionability, aggression and emotion. Thus, these children violate social relationships, communication and cooperation.
Behavioral disorders along with ADHD symptoms are common, but not always; not all children with ADHD suffer from behavioral disorders. In children with ADHD more often bedwetting, they are worse than falling asleep and in the morning is often manifested drowsiness.
Studies have shown that impulsivity and hyperactivity in adolescence, many reduced even if there are other violations. People who suffered from a severe form of childhood ADHD in adolescence and adulthood cannot adapt socially.
ADHD (usually in combination with behavioral disorders) may indicate a variety of personality disorders. ADHD contributes to the development of alcoholism and drug addiction, which hide his symptoms and make it difficult to diagnose.
Common physiological ADHD symptoms
ADHD is caused by mild residual brain injury, which includes the presence of light diffuse neurological symptoms, impaired coordination, hyperactivity, moderately expressed sensors and motor system, speech disorders, behavioral disorders, increased distractibility, lack of skills, the specific difficulties of learning combined with a delay in the formation of language and speech.
ADHD symptoms are almost always appears to 7 years. Average age to see a doctor is 8-10 years, since it is at this age learning and household duties requires the child to independence, concentration and determination. Children at earlier age can be diagnosed with ADHD at first contact with the doctor usually does not give, and wait a few months, during which symptoms must persist.
More than half of children who have been diagnosed with ADHD in the primary grades, have kept this syndrome in adolescence, which is accompanied by a concomitant condition. These teens tend to use psychoactive drugs, struggling to adapt to the team. In 30-70% of cases, the symptoms of ADHD persist in adults.
