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.

There are many different forms of dementia and each has its own cause. Some of the main type of dementia is Alzheimer’s disease, which is the most common form of dementia affecting 50%-70% of dementia patients (Alzheimer's australia, 2005). This is a degenerative illness which attacks the brain, this is achieved buy tangles which are in the middle of shrunken brain cells and plaques which eventually cause the brain cells to die meaning information can no longer be recalled or assimilated. There are also other types of dementia which include vascular dementia which is caused by circulation of the blood to the brain, Parkinson’s disease which is a disorder of the

There are many variations of dementia syndrome but there are certain causes that are more common. These are:

Abnormal changes happen in the brain, and it appears as a sponge-like holes and gaps, causing deterioration in the areas of the brain. This can turn into spongiform degeneration that results in the progressive neurological and neuromuscular symptoms that are associated with CJD. This disorder is a result from a mutation in the gene that regulates the production of the human protein or direct transmission with abnormal protein in infected brain tissue. Scientist believe that there is a transmissible agent that is responsible for causing CJD. This is a slow virus, since it can take many years from exposure to the appearance of

Dementia effects your memory and a person’s ability to achieve a normal everyday task and activities.

Finally the brain has shrunk and damage is widespread throughout the brain.

A few of these abnormal behaviors include confusion, agitated, wandering, and depression. There are multiple diseases that can potentially be a causation of dementia. A few examples are Huntington’s disease, Parkinson’s disease, and Lewy body disease. Dementia should not be confused with delirium or memory loss due to natural aging (ASHA, 2015).

1.1 neurodegenitve disease is a common cause of dementia . which means the brain cells known as neurons are dieing quicker then the rest of the brain which leads to more of a decline in the persons mental health such as memory loss language and some of there physical abilitys. it dpend on what part of the brain is affected by the dementia. also other causes of demtia are brain tumors head injurys

Alzheimer’s is when a person has short term memory loss with progressive, irreversible confusion and disorientation. This progressive deterioration of the brain is caused by the destruction of neurons in the central nervous system (CNS) neurons. The destruction of these neurons lead to problems with memory and language, thinking and behavior”. Celular destrucyion is related to the buildup of analoid plaques ans neurofibrillary tanglwa in the brain” (Kinn’s) The body system that is affected when a patient has Alzheimer’s Disease is the Neurological System. Alzheimer’s is a form of dementia. Some forms of dementia

The research shows that these symptoms are common among the older people. The most common disease is Alzheimer but there are some diets that help the person to prevent the condition.
