A cognitive impairment means there is a change in how a person thinks, reacts to emotions, or behaves.
What is going on in the body?
A person can be born with a cognitive impairment. In this case, it is usually termed mental retardation. It may result from a birth injury, such as a lack of oxygen. It may also result from a defect as the baby was formed. A cognitive impairment also may occur later in life, following an injury or as part of a disease.
What are the signs and symptoms of the condition?
A cognitive impairment interferes with the body's normal function. The change may be minor and have little or no impact on a person's daily functioning. In other cases, the impairment may be obvious. A cognitive impairment can range from mild memory problems to exaggerated emotional reactions. It can also entail the complete inability to think independently.
What are the causes and risks of the condition?
A cognitive impairment may be present when a child is born, which is known as mental retardation. It may also be the result of: · abuse of prescription medicines, chemicals, street drugs, or alcohol · a disease, such as Alzheimer disease · a side effect of some medicines · a trauma such as head injury
Frail, elderly people who are removed from a familiar setting often develop cognitive problems. This may occur when they go to a hospital because of illness or when they are moved to a nursing home. Depending on the cause, cognitive impairments may be temporary or permanent.
What can be done to prevent the condition?
Cognitive impairment can occur at any age and cannot always be prevented. However, the following measures may be helpful: · avoiding illegal drugs · drinking alcohol in moderation or not at all · following sports safety guidelines for children, adolescents, and adults · obtaining prenatal care during pregnancy · using medicines only as directed
How is the condition diagnosed?
In some cases, mental retardation can be diagnosed at birth. An infant with Down syndrome, for example, is often identified by characteristic features. The diagnosis is confirmed with a chromosome analysis.
Other tests used to diagnose cognitive impairments include: · cognitive testing, which provides information about the individual's memory and thinking skills · cranial CT scan · cranial MRI · spinal tap
What are the long-term effects of the condition?
A person with cognitive impairment can often live a nearly normal life.
Dementia is a long-term condition that normally affects people aged 65 and over, younger people can be affected. Having dementia can cause loss of key functions to the brain, such as; loss of memory; confusion; speech and language problems; loss of ability to make judgements; loss of concentration; difficulty in processing information; changes in behaviour and personality. These all lead to a person not been able to function properly. The person’s ability to function deteriorates over a period of time and is usually at least 6 months before positive diagnosis of dementia can be made. Dementia is caused when the brain is damaged by diseases such as Alzheimer’s which is the most common of dementia, vascular which is a series of mini strokes,
People who suffer from Dementia lose their ability to do a daily task. They are unable to do shopping, prepare meals, deal with bills and money. They can forget to lock the door, turn off the cooker or water. They may have difficulties with their mobility and coordination. Person who has a disability experiences this same problem.

“…a group of symptoms that are caused by changes in brain function. Dementia symptoms may include asking the same questions repeatedly; becoming lost in familiar places; being unable to follow directions; getting disoriented about time, people, and places; and neglecting personal safety, hygiene, and nutrition. People with dementia lose their abilities at different rates.”
Doctors need a sure way to diagnose the disease before treatment or studies can be done. The diagnosis is an autopsy of brain tissue examined under a microscope. In addition, medical history, a physical exam, and mental status tests are used for diagnosis (Posen, 1995). Often, tests are done to rule out other potential causes of the dementia. This allows the identification of other causes of thinking and behavioral changes to be made before concluding that the patient has Alzheimer’s or another form of dementia. The tests that are requested to be done include CT and MRI scans to rule out strokes or brain tumors which could account for change in memory and behavior; thyroid and psychological tests which can also detect thinking and behavior problems (Posen, 1995).
People with dementia may have problems with short-term memory, keeping track of their belongings, keeping up with plans, remembering appointments or travel dates. Many dementias are progressive. This means that symptoms start out slowly and gradually get worse with time. Alzheimer’s and other types of dementia are diagnosed based on careful medical history, a physical examination, laboratory tests, and the characteristic changes in thinking, day-to-day function and behavior related to each
This condition is preceded by a decline in the baseline performance that is thought to be abnormal for the person’s age and abilities. Mild cognitive impairment is characterised by beginning of changes in memory as well as performance of daily. Severe cognitive impairment is compounded with the more serious loss of performance of the mental processes, resulting in that a person cannot live on their own (Fann et al, 2005). The health, social and economic impacts of cognitive impairments are clear to many health care providers. However, there has not been enough national attention given to this health concern.
Alzheimer’s disease or AD is an incurable disorder of the brain that results in loss of normal brain structure and function. In an AD brain, normal brain tissue is slowly replaced by structures called plaques and neurofibrillary tangles. The plaques represent a naturally occurring sticky protein called beta amyloid and in an Alzheimer’s brain, sufferer’s tend to accumulate too much of this protein. Neurofibrillary tangles represent collapsed tau proteins which, in a normal brain along with microtubules, form a skeleton that maintains the shape of the nerve cells. In Alzheimer’s disease, the tau proteins break loose from their normal location and form tangles. Without the support of these molecules, nerve cells collapse and die. As normal brain structure is lost with progression of the disease, brain function also degenerates. Patients afflicted with Alzheimer’s disease display a gradual mental decline. Initially, and most apparently, there is a loss of short-term memory. Eventually, as a patient progresses to later stages of the disease, the brain becomes so damaged that patients can no longer communicate or recognize immediate family or even themselves. They have difficulty walking and standing and frequently fall. In the final stages, they lose bladder and bowel control and have difficulty with swallowing, frequently leaving them malnourished and dehydrated. Eventually, they are forced to remain bedridden and, without the help of life-prolonging measures provided in a hospital, die. However, this level of deterioration is severe and may take as long as twenty years. Because of the disease’s slow progress and its usual later start in a person’s life, a victim of AD will usually die first of natural causes. Under the objectives ...

In this day and age, it seems as though almost everyone has experience a loved one taken away form a very serious disease known as Alzheimer’s disease. Alzheimer’s disease is unbelievably devastating for everyone affected by it. This disease is causing major economical problems such as less occupancy in the nursing homes, and hospitals due to the rising population of elderly men and women being diagnosed with it everyday. Because there is not yet a cure for this disease and the percent of the population being diagnosed keeps rapidly rising, more time and money needs to go towards Alzheimer’s research.
Alzheimer's Disease Introduction to Alzheimer's Alzheimer's disease is a progressive, degenerative disease of the brain. It was first described by the German neuropathologist Alois Alzheimer (1864-1915). in 1905. This disease worsens with advancing age, although there is no evidence. that it is caused by the aging process.
Down syndrome, a genetic disorder, is the most common cause for intellectual disabilities, occurring at an average of one out of every 700 births (CDS, 2006). This disorder is caused by the extra chromosome 21 (also known as Trisomy 21). According to Hassold and Sherman (2002), the probability of giving birth to a child with DS is not linked to any race, ethnicity, socioeconomic status or geographic location. Maternal age seems to be the only etiological factor that may cause DS.
the baby is at any subsequent risk of having DS for early prognosis and intervention. Cognitive
It is said that memory declines as people age, and this can be just a natural part of life. However, in many cases as people grow older, they develop a mental disorder known as Alzheimer’s disease. Alzheimer’s is a disease that causes problems with memory, thinking, and overall behavior, and progressively becomes a bigger problem. Alzheimer’s is the most common form of dementia and is a very common disease in people over the age of 65. This terminal disease puts tremendous stress on the victim and the victim’s family. A cure for Alzheimer’s has yet to be discovered; however, through healthy and constant use of the brain and the aid of certain drug treatments, Alzheimer’s disease can be both naturally and medically prevented.
A myth about Alzheimer disease says that nothing can be done about the disease. This is not true. Much can be done to assist the person with Alzheimer’s disease to maintain the highest possible level of functioning as long as possible and in providing the highest quality of life.
