Dementia with Lewy bodies is closely related to Parkinson's disease and often has some of the same symptoms, including difficulty with movement. Front temporal dementia (including Pick's disease) – In front temporal dementia, the front and side parts of the brain are damaged over time when clumps of abnormal proteins form inside nerve cells, causing them to die. At first, changes in personality and behavior may be the most obvious signs. Depending on where the damage is, the person may have difficulties with fluent speech or may forget the meaning of words or objects. 2) Memory problems are usually the most obvious symptom in people with dementia.
This causes a gradual decline in mental ability. The key functions of the brain that are affected by dementia are the temporal lobe, frontal lobe, parietal lobe, occipital lobe, cerebrum lobe and the hippocampus 3. Depression, delirium and age related memory impairment share a lot of the symptoms of dementia. For instance with depression their memory may be affected and they may find it difficult to retain new information, also it is quite common for people to become forgetful as they age. This may be why people mistake them for dementia.
A person’s own immune system attacks the myelin sheath that surrounds the axon of the nerves. Once the myelin sheath is damaged, the nerves cannot transmit signals properly. Nerve damage leads to muscle weakness, loss of reflexes, and numbing or tingling of the hands and feet. This is caused by the muscles loss of ability to respond to the brains commands. GBS is not often fatal but in rare cases people have died from GBS.
This leads to the decline of a person’s mental health and sometimes physical abilities. The gradual changes and damage to the cells of the brain are caused by a build-up of abnormal proteins in the brain. There are irreversible changes that occur in and individual’s brain lead to: * Death or the loss of the nerve cells * Lots of cognitive deficits, including memory lose * Decline in language understanding * Unable to recognise family and friends * The decline in the overall mental function The abnormal proteins are different in each type of neurodegenerative dementia. In most cases dementia is not inherited from family members directly. Although there a small amount of cases of Alzheimer’s and frontotemporal dementia can be inherited from a previous generation.
3. How does damage to the PNS affect the body? c. Some may experience temporary numbness, tingling, and pricking sensations, sensitivity to touch, or muscle weakness. Pthers may suffer from more extreme symptoms including, burning pain, muscle wasting, paralysis, or organ or gland dysfunction, people may become unable to digest food easily, maintain safe levels of blood pressure, sweat normally, or experience normal sexual function. In the most extreme cases, breathing may become difficult or organ failure may occur.
Those experiencing hypoglycaemia may exhibit aphasia--the inability to use or understand words. Hypoglycaemia can also produce hemiplegia, the inability to control motor functions, often on just one side of the body. Tumours or masses occurring in the central nervous system or brain can also mimic a stroke. Although masses typically increase in size progressively over time, the onset of symptoms may be sudden, just as a stroke. As the mass impedes on the brain or blood vessels, symptoms such as seizures and speech problems can occur.
It is not clear whether these are from lupus itself or whether there related to the general stress and fatigue of having a chronic illness. More severe symptoms such as difficulty with memory loss, concentration, numbness or weakness of the arms and legs are not to common. People with this disease may also develop inflammation of the heart sac, which may cause severe or sudden pain on the center of the left side of the chest that may spread to the neck, back, shoulders or even arms. People may also develop inflammation around the lungs, which may cause a stabbing chest pain and coughing. Many people tend to lose weight when their disease is active.
This may be as a result of a stroke or mini strokes although it can be caused by preventable conditions such as high blood pressure, diabetes and high cholesterol. Dementia with Lewys Bodies (DLB) is caused by small deposits of proteins found in the nerve cells of the brain. Their presence in the brain leads to the degeneration of brain tissue. This is the third most common form of dementia. Rarer forms of dementia are: Fronto temperal dementia which is brain damage usually focused in the front or temporal parts of the brain.
As dementia progresses, the person may develop behavior problems which may seem out of character. These behaviors may include repetitive questioning, pacing, restlessness or agitation. A person with dementia, especially in the later stages, may also show signs of physical symptoms such as muscle weakness or weight loss. Changes in sleep pattern and appetite are also common. 2 - The brain, along with the spinal cord, makes up the central nervous system, and it is this that controls all of our body’s functions.
The midbrain is the part of the brain that controls our body movements. An individual with Parkinson’s disease will usually start to display one or more of the following symptoms: * Trembling of the head , arms , and legs * Stiffness in the body * Poor balance * Difficulty walking * Difficulty talking There is no known cure for Parkinson’s disease, but some of the symptoms can be treated. Dopamine is a very important neurotransmitter in the brain (Stangor, 2010). In regards to Parkinson’s disease, dopamine acts like a messenger between the substantia nigra and the corpus striatum, in
