Dementi The Cause Of Alzheimer's Disease

Dementia is a cognitive disorder which causes a loss of brain functions which mainly affect memory .

Dementia is a loss of brain function. If affects memory, thinking, language, judgement and behaviour. Dementia is progressive, so the symptoms will gradually get worse. In a later stage of dementia people will find it hard to carry out daily tasks and will come dependant on other people.

The term dementia describes a set of symptoms which include loss of memory, mood changes and problems with communication and reasoning. These symptoms occur when the brain is damaged by numerous certain diseases. Dementia is progressive, which means the symptoms will gradually get worse. How fast dementia progresses will depend on the individual person and what type of dementia they have. Each person is unique and will experience dementia in their own way.

Dementia is a term used to describe a collection of signs and symptoms that happen to the brain when it is affected by the progression of certain diseases such as vascular dementia (when brain cells die due to lack of oxygen) and Alzheimer’s disease (a specific brain disease). Some of the affects these diseases have are on a person’s memory, language and communication abilities, behaviour and ability to make rational judgements.

Dementia is a broad term used to describe the symptoms that occur when the brain is affected by specific diseases and conditions.Dementia is a progressive disease and the symptoms will get gradually worse.

Dementia is a term used to describe the symptoms of a number of illnesses which effect the function of the brain. It is an umbrella term describing the progressive decline in a person’s cognitive ability. The type and severity of symptoms varies with each type of dementia and is usually has a gradual onset, is progressive and irreversible. (1)

Dementia and Alzheimer’s disease are often confused because of the similarities and mysteriousness that they share. According to the National Institute on Aging (NIA), the are actually very different in many ways. Dementia is term used to describe a disorder that impairs the mental processing of thoughts and memory. Other forms of dementia besides Alzheimer’s are Huntington’s Disease, Parkinson’s Disease and Creutzfeldt-Jakob disease. Alzheimer’s Disease is a form of dementia and is the most common, from 60-70% of all dementia cases. To determine cause of dementia, doctors will use different mental evaluations, brain scans, and blood tests. Alzheimer’s is diagnosed through the evidence that the brain scans provide. One significant difference between Alzheimer’s and dementia is the fact that Alzheimer’s is a nonreversible disease. Some forms of dementia are temporary or reversible but Alzheimer’s has no cure and is degenerative.

Dementia is a progressive illness that usually occurs over a period of time one of the earliest signs of dementia is problems with a persons memory, this can result in the individual behaving and communicating differently .

Dementia describes a set of symptoms that may include memory loss and difficulties with thinking, problem-solving or language. These changes are often small to start with, but for someone with dementia they have become severe enough to affect daily life.

Dementia is a word used to describe a group of symptoms including memory loss, confusion , mood changes, and difficulty with day-to -day task. There are many causes of dementia wit Alzhaimer`s the most common.

Dementia is a set of symptoms that affect the way people think and interact with each other. It is not a disease, but can often be linked to a disease or damage done to the brain. Short-time memory, mind, speech and motor skills are affected. Certain forms of dementia cause a change in the personality of the individual. A person suffering from dementia will lose certain skills and knowledge they already had. This is the main difference to other conditions that affect the mind. People who suffer from learning problems, or lower intelligence will never acquire certain skills, people suffering from dementia will lose skills they have acquired. Dementia is

Dementia is a clinical state caused by neurodegeneration and characterized by a loss of function in cognitive domains and behavior. There are several different causes of dementia including Alzheimer’s disease (AD), vascular dementia, dementia with Lewy bodies, and frontotemporal dementia (FTD). Hippocampal sclerosis of aging (HS-aging) is prevalent in people of advance age, manifests with distinct neuropathological properties, and can be present with or without other dementia causes and vascular diseases [1].

During the normal aging process cerebral blood flow decreases almost 50%, this decrease reflects an overall decrease in global perfusion, which leads to cerebral atrophy. Cognitive impairment most commonly occurs in patients with cardiovascular disease; individuals with a sedentary lifestyle show a decrease in neuronal plasticity and learning. Subsequently aerobic exercise actually reduces the amount of brain tissue loss, increases memory function and increases gray matter volume in prefrontal areas. In another study men who participated in endurance exercise had increased cerebral blood flow of the middle cerebral artery, which results in lower cerebrovascular risk factors in physically active elderly individuals, providing a protective mechanism against cerebral atrophy (Wiggens, Simovance).

Dementia is a progressive diagnosis that takes place over months or years. Dementia occurs in stops compared to other psychological diagnoses in the elderly and age is a major risk factor. The older the adult the increased risk of dementia occurring. There are different forms of dementia, but Alzheimers is the most prevalent of all the types. Dementia, as stated above, is associated with delirium during an acute illness and is hard to identify in patients with underlying dementia. Dementia causes a decline in executive fncitoning and memory, as a result, decreasing the patient's overall quality of life because their activities of daily living become more and more limited. Behaviors and changes in mood are also noted in these patients, such as;

Dementia is a "clinical syndrome, or condition that presents several different symptoms of which memory problems and impaired intellectual functioning are the hallmark" (Lillrank). Dementia is actually a term used to describe a wide range of symptoms. Two of the most common types of dementia are: Vascular dementia and Alzheimer's. Some symptoms of dementia include loss of short-term memory. Other initial manifestations can include confusion,
