Understand the process and experience of dementia(DEM 301)

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.

1.3 Individual’s process information in different ways therefore depending on their abilities will depend on their limitations of individuals with dementia. Some people are aware of their limitations, this may make them feel sad for the way they are now and making them worried about the future. Usually as the disease progresses, the level of self-awareness will most likely decline as well. In earlier stages of dementia the person you care fore may deny or not understand that they have the disease and this can then result in them not realising their own limitations in their abilities, such as driving, cooking etc.

Analyzing the brain cells, it has been revealed that there are a number of chances that change the brain takes place, causing neurofibrillary and amyloid plaques that lead to Alzheimer’. Viral infection and immune system of the body can also be more causes (Dennis, 2005).

The results of this study show us the brain is not in fact symmetrical and the two hemispheres in the brain work in different ways. The left hemisphere is known to play the dominant role, which is in control of all complex behavioural and cognitive processes as for the right hemisphere it only plays a minor role. This report will further analyse how different the two hemisphers is the dominant side of the brain.

The cerebrum makes up three quarters of the brain. In the cerebrum, there is the ability to problem solve, move, think and feel (“Alzheimer’s Disease,”n.d.). The cerebrum can be divided into two halves, the right hemisphere and the left hemisphere. Each hemisphere has four lobes, occipital lobe, parietal lobe, temporal lobe, and frontal lobe. Each lobe has specific tasks. For example, the occipital lobe is responsible for visual images.

other brain functions. Dementia is irreversible and has a huge impact on the family and

More than 47 million people around the world have dementia. Dementia refers to a deterioration in cognitive function, including memory and comprehension. Alzheimer’s disease is the most common cause of dementia but other conditions can also be responsible. Dementia is usually chronic and progressive, so it has a major impact on people’s lives.

Dementia is the loss of mental functions such as thinking, memory, and reasoning that is severe enough to interfere with a person's daily functioning. Dementia is not a disease itself, but rather a group of symptoms that are caused by various diseases or conditions. Symptoms can also include changes in personality, mood, and behavior. In some cases, the dementia can be treated and cured because the cause is treatable. Examples of this include dementia caused by substance abuse (illicit drugs and alcohol), combinations of prescription medications, and hormone or vitamin imbalances. In some cases, although the person may appear to have dementia, a severe depression can be causing the symptoms. This is known as pseudo-dementia (false dementia) and is highly treatable. In most cases, however, true dementia cannot be cured.

The left hemisphere controls the right half of the body that controls language and logical tasks. The right hemisphere controls the left half of the body creativity and emotions. Split-brain reveals that depending on what side of the brain is damaged, the two brain hemisphere may have information sharing problems, due to the separation of the corpus callosum . "a split-brain patient looking at an image through the left eye may not be able to name the picture because the information is only available in the largely nonverbal right hemisphere". Module 3.2 (n.d) The Nervous System.

Cerebrum: The cerebrum is the main part of the brain, which has two halves, or hemispheres. The right hemisphere controls the left side of the body and deals with things such as creativity, music, and art. While the left hemisphere of the cerebrum controls the right side of the body and is in charge of language, problem solving, and math. The cerebrum’s many tasks are carried out by its outer layer, or its cortex. This has distinct areas that have different roles. Motor areas trigger movement; sensory areas deal with the senses, while association areas clarify information.

In the second test, the experimenters found that while both sides of the brain could recognize an object via touch, only the left hemisphere can articulate it into spoken words. The right side can only express through nonverbal means. In the third test, both sides of the brain were able to identify objects that either is what is described or associated to what is described by the experimenter. From these tests and some others, the researchers were able to discover that each hemisphere of the brain is able to act independently within the confines of their confines. Both the left and hemispheres are able to processes the senses and have motor functions. However, each hemisphere has its own particular aspects that it specializes in; for example, the left hemisphere specializes in speech, while the right hemisphere specializes in spatial skills. As a result of this study, many other studies have been performed to determine the extent of the two brain theory. After these studies, the psychology community has adopted the concept that each hemisphere of the brain specializes in certain skills and functions but can also think on its own. This knowledge also has a more practical usage. Medical professionals and rehabilitation centers can utilize the knowledge of what part of the brain controls what to better help individuals recover from brain damage by knowing what to focus on during recovery and

Did you know that the brain is broken up into different sections? It is composed of three different parts: the cerebrum, cerebellum, and the brainstem. The cerebrum is the largest part of the brain and it composed of a right and left hemisphere. It controls higher functions such as interpreting touch, vision and hearing. However, did you know that the cerebrum also controls speech, reasoning, emotions, learning, and fine control of movement. The funny thing is that every person is different, and that we are learn new stuff everyday.

When doctors examine Alzheimer's brain tissue under the microscope, they see two types of abnormalities that are considered trademarks of the disease: Plagues (clumps of beta-amyloid protein) and Tangles (abnormal structure of tau, a protein).

Speech and language centers are the specialty of the left hemisphere. The left hemisphere may be referred to as the verbal hemisphere. The left hemisphere is better at producing math skills and logic. The right hemisphere’s specialty is spatial abilities, face recognition and processing music. It helps one to understand visual imagery and make sense of what is viewed. The right hemisphere plays a role in language, particularly in interpreting context and a person's tone. Brain asymmetry is necessary for proper brain function. This allows the two sides of the brain to become specialized, by which the processing capacity is increased, thus avoiding situations

The cortex consists of four sections, called "lobes". The frontal lobe is connected to reasoning, planning, speech, movement, emotions, and problem solving. The parietal lobe is associated with balance, recognizing, and movement. The occipital lobe is associated with vision. The temporal lobe is connected to hearing, memory, and speech. The cortex is highly wrinkled, making the brain more convenient, as this increases the brain's surface area, giving it more room for neurons. The cerebrum is divided into two hemispheres- the left hemisphere, and the right hemisphere. The right hemisphere is associated with creativity, and the left one is linked with logic. A bundle of nerve fibers, known as the corpus callosum connects these "hemispheres" (Brain Structures and their Functions). The cerebellum, which is also known as the "little brain", is similar to the cerebrum, since it also has two hemispheres and a highly folded surface. This part of the brain is linked with movement and balance. The cerebellum is assumed to be older than the cerebrum "evolutionarily" (Brain Structures and Their Functions). The brain stem controls basic life functions such as blood pressure, breathing, and heartbeat. Scientists say that the brain stem is the simplest part of the brain (Brain Structures and Their Functions).
