Dementia
Dementia is an organic brain syndrome which results in global cognitive impairments. Dementia can occur as a result of a variety of neurological diseases. Some of the more well known dementing diseases include Alzheimer's disease (AD), multi-infarct dementia (MID), and Huntington's disease (HD). Throughout this essay the emphasis will be placed on AD (also known as dementia of the Alzheimer's type, and primary degenerative dementia), because statistically it is the most significant dementing disease occurring in over 50% of demented patients (see epidemiology).
The clinical picture in dementia is very similar to delirium, except for the course. Delirium is an acute transitory disorder. By contrast Dementia is a long term progressive disorder (with the exception of the reversible dementias). The course of AD can range anywhere from 1.5 to 15 years with an average of about 8.1 years (Terry , 1988). AD is usually divided into three stages mild, moderate, and severe. Throughout these stages a specific sequence of cognitive deterioration is observed (Lezak, 1993). The mild stage begins with memory, attention, speed dependent activities, and abstract reasoning dysfunction. Also mild language impairments begin to surface. In the moderate stage, language deficits such as aphasia and apraxia become prominent. Dysfluency, paraphasias, and bizzare word combinations are common midstage speech defects. In the severe stage the patient is gradually reduced to a vegetative state. Speech becomes nonfluent, repetitive, and largely non-communicative. Auditory comprehension is exceedingly limited, with many patients displaying partial or complete mutism. Late in the course of the disease many neuropsychological functions can no longer be measured. Also primitive reflexes such as grasp and suck emerge. Death usually results from a disease such as pneumonia which overwhelms the limited vegetative functions of the patient.
Dementia is commonly differentiated along two dimensions: age and cortical level. The first dimension, age, distinguishes between senile and presenile dementia. Senile dementia is used to describe patients who become demented after the age of 65, whereas presenile dementia applies to patients who become demented prior to that age. Late onset AD (LOAD) also known as senile dementia Alzheimer's type (SDAT) is the predominant cause of senile dementia. Early onset AD (EOAD) is the most frequent cause of presenile dementia, but HD, Pick's disease and Creutzfeldt-Jakob disease though not as frequent are also important causes in presenile dementia.
Although Alzheimer’s disease appears to be the most common cause of dementia, “more than 50 conditions are associated with dementia, including degenerative ...

Alzheimer’s can be diagnosed before age 65, although rare, and is caused by a mutation in 3 known genes. About 5 percent of those who are under 65 and possess the ailment have AD in their family history. Given that the symptoms of AD are caused by plaque in the brain, causing loss of nerve cells that help the body communicate with the brain, mutations to these genes; amyloid precursor protein, presenilin 1, and presenilin 2 cause a excessive production of certain proteins (primarily a B-42 form of amyloid protein), and therefore spark an excessive growth of plaque cells which are toxic to the neurons of the brain. For those cases of Alzheimer’s that occur after age 65, a genetic mutation has yet to be proven, although some may be linked, to the fact that a difference may cause an increased chance of developing the ailment. Whatever the case may be for patients over 65 years old, the disease and its symptoms are caused by neurofibrillary tangles of almyloid plaques. It is impossible for someone to test positive for Alzheimer’s Disease, because the only way to determine an affirmative case i...
Alzheimer’s is a result from a combination of factors that cause progressive brain deterioration that affects the memory and behavior of an individual. There are two known risk factors. The first risk factor is age. Alzheimer’s usually affects people older than 60, and rarely affects those younger than 40. The average age
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
Schizophrenia is a serious, chronic mental disorder characterized by loss of contact with reality and disturbances of thought, mood, and perception. Schizophrenia is the most common and the most potentially sever and disabling of the psychosis, a term encompassing several severe mental disorders that result in the loss of contact with reality along with major personality derangements. Schizophrenia patients experience delusions, hallucinations and often lose thought process. Schizophrenia affects an estimated one percent of the population in every country of the world. Victims share a range of symptoms that can be devastating to themselves as well as to families and friends. They may have trouble dealing with the most minor everyday stresses and insignificant changes in their surroundings. They may avoid social contact, ignore personal hygiene and behave oddly (Kass, 194). Many people outside the mental health profession believe that schizophrenia refers to a “split personality”. The word “schizophrenia” comes from the Greek schizo, meaning split and phrenia refers to the diaphragm once thought to be the location of a person’s mind and soul. When the word “schizophrenia” was established by European psychiatrists, they meant to describe a shattering, or breakdown, of basic psychological functions. Eugene Bleuler is one of the most influential psychiatrists of his time. He is best known today for his introduction of the term “schizophrenia” to describe the disorder previously known as dementia praecox and for his studies of schizophrenics. The illness can best be described as a collection of particular symptoms that usually fall into four basic categories: formal thought disorder, perception disorder, feeling/emotional disturbance, and behavior disorders (Young, 23). People with schizophrenia describe strange of unrealistic thoughts. Their speech is sometimes hard to follow because of disordered thinking. Phrases seem disconnected, and ideas move from topic to topic with no logical pattern in what is being said. In some cases, individuals with schizophrenia say that they have no idea at all or that their heads seem “empty”. Many schizophrenic patients think they possess extraordinary powers such as x-ray vision or super strength. They may believe that their thoughts are being controlled by others or that everyone knows what they are thinking. These beliefs ar...

Dementia can occur in relation to many different illnesses. Some of the most common of which are Huntington’s Disease,
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 the 17th and the 19th century dementia was synonymous with insanity. Still many knew that people with this disease suffered from permanent damage that was irreversible unlike mental disorders where the brain remains intact (2006). Dementia was often known as senile which is common with old age. Studies through the years have shown that it is much more serious and causes damage to areas of the brain. Alois Alzheimer in 1910 noticed tangles, plaques, and arterio...
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.
Alzheimer disease generally occurs in people over seventy five years of age; however it does strike people in their forties, fifties, and sixties, but this is rare. When Alzheimer’s disease occurs prior to the age of sixty five, it is referred to as early onset Alzheimer’s.
This usually occurs in older adults aged above 65; however, it is a disability and not a normal symptom of aging. Chances of inheritability are present, but it depends on the individual and the type of dementia (Alzheimer Australia, 2011). The Global Deterioration Scale provides a detailed explanation of the seven stages of cognitive decline in dementia (Alzheimer’s Association of Canada, 2005). Types of Dementia There are four main types of dementia, with AD being the most widespread form. It accounts for almost two thirds (50 -70 percent) of the cases and thus more extensively studied (Miller, 2009)....
... and duration varies from person to person. It depends on multiple factors, including the age of diagnosis and other medical conditions. The signs and symptoms start with cognitive disturbance as all other forms of dementia begin. We should refrain from being prejudiced and judgmental because of not taking the time to truly understand this disorder and how it may affect one’s life. Education and patience are the best ways to tackle this issue. In this paper, relevant topics involving dementia were discussed. Part one covered the pathology and staging of dementia. Part two explained the most common types of dementia that many people are diagnosed with. Part three summarized the treatment methods used to manage the disorder. We should apply a professional, respectful, and empathic approach while maintaining specific culture traditions to achieve a successful outcome.
