ADHD or Attention deficit hyperactivity disorder refers to those psychological disorders, which significantly alter a child's behavior and considerably affects his or her relationships with others. This condition is seldom preceded by perceptible symptoms and even when they do, they are difficult to decipher. However some of them are:

1. Self-centered: Those children who suffer from the attention deficit hyperactivity syndrome tend to be encapsulated in their own subjectivity. Though this does seem harmless apparently, this tendency may lead them to be insensitive to other's needs and wants.
2. Emotional outbursts: ADHD makes children extremely susceptible to frequent emotional outbursts and makes them erratic.
3. Difficulty in concentration: Children who suffer from ADHD face extreme difficulty in concentrating or focusing on things. Many a times they fail to repeat what was told to them.

There might be several causes which can contribute to the development of this disorder. Some of them are:

1. A drastic change in the child's lives: A sudden or a drastic change like the divorce of parents may severely affect the child and maim him emotionally. This may lead to the development of this disorder.
2. Depression: Though always associated with adults, depression can be and is common among children as well. In such instances, a consequent development of ADHD is highly plausible.
3. Bipolar disorder: Bipolar disorder refers to excessive and incomprehensible mood swings. Many children suffer from it in their early lives, making them susceptible to ADHD.

Notwithstanding the ambiguity and the erratic nature of the disorder, there might be preventive measures which parents might adopt to deter the outbreak of the disorder. Some of them are:

1. Less use of preservatives: Parents must be careful about what their children eat. Those foods which contain a certain amount of preservatives tend to aggravate the disorder thereby causing more harm than good.
2. Consider alternative forms of medications: Another way of dealing with this problem is by exploring other forms of medications and not sticking to one form. In this respect, practicing yoga may be very beneficial.

The partial or total inability to hear is known as hearing impairment or hearing loss. It can be present at birth, or develop later in life.

There are a number of factors, which may cause hearing loss

1. Age - Age is the biggest factor when it comes to the loss of hearing, and you may lose the ability to hear as you age. This condition is known as presbycusis. It becomes difficult to understand high-frequency sounds like that of a child or a woman when you get old.

2. Noise - When you are exposed to loud noises for a prolonged period of time, it damages your ears. This leads to loss of hearing. 5% of the total population of the world is affected by noise (the degree of suffering varies). It may be a result of continuous exposure to loud music or a sudden exposure to a loud noise like an explosion.

3. Hereditary disorders - Hearing disorder may be inherited by the dominant or recessive genes of parents in the child. 70-80% of these cases inherit from the recessive genes, whereas 20-25% inherit hearing loss from the dominant genes.

4. Trauma - Serious injuries of the head/ears may cause loss of hearing, which may be either temporary or permanent. When damage is caused to the brain, the brain fails to process the message conveyed by the ears. So even if the ears are totally functional, a person may face the problem in hearing.

5. Perinatal problems - The ototoxic effects on the fetus due to excess intake of alcohol during pregnancy lead to hearing the loss in about 64% of the infants born to alcoholic mothers.

Also, premature birth can be associated with hearing loss due to high risk of being exposed to noise in neonatal units.

Knowing about the causes of hearing loss can lead you a step closer to preventing this disorder as you age.

Here are some useful tips that can help prevent hearing loss:

1. Be more aware - You should be diligent and aware of the situations, which may risk your hearing ability and should try to avoid such situations as much as possible. Limit your exposure to sources of hazardous noises like firearms, firecrackers, concerts and clubs.

2. Take precautionary measures - If your occupation calls for working at an environment of loud noises, use earplugs or earmuffs to block out the excessive noise. Also, make sure that you work in a place where employers take all the necessary measures of noise control under the federal or state regulations.

3. Monitor your use of gadgets - Monitor and control the use of hearing devices, and try to reduce the use of headphones/ earphones as much as possible.
