Creutzfeldt-Jakob disease, otherwise known as CJD, is a form of brain damage that leads to a rapid decrease of mental function and movement. CJD has been thought to be caused by a protein called prion. Prions cause normal proteins to fold abnormally, thus causing other proteins functions to then be affected. There are several types of Creutzfeldt-Jakob disease which are all very rare. CJD can be grouped in three categories: sporadic disease, familial cases, and iatrogenic cases.
When discovered, these remnants of corrupted brain cells are the primary method today in identifying Alzheimer's disease. Granulovacuolar degeneration is when fluid filled vacuoles are evident in the cells of the hippocampus. The dendrites and nucleus in the cell disintegrate entirely, lost in the body’s disposal system (Talan, 2011). The brain actually loses mass and shrinks. Eventually so much of the brain has been lost that it can no longer support
When the organ in our body is deprived of oxygenated blood that organ or part of it will die. This is exactly what happens in vascular dementia. The conditions which can cause these problems are preventable and include diabetes, heart problems, high blood pressure and cholesterol. Rarer forms of dementia are: • Creutzfeldt-Jakob disease known as CJD is caused by prion disease. Prions are proteins in body and when these protein cluster together in the brain they cause brain cells to die
These lymphocytes or the white blood cells are the main part of the lymphatic system that is affected. These lymphocytes more specifically the b type, or T-cells, lymphocytes begin to fail and are no longer able to fight the typical infections that occur in the body. In more severe cases Burkitt’s tumors can occur which causes severe infections to occur on any exposed part of the body due to the infected T-Cells being unable to hone in on any infections due to their being immature thanks to the rapid
Spinal Muscular Atrophy Spinal muscular atrophy or SMA for short is a neuromuscular disease. SMA represents a group of autosomal-recessive disorders, leading to muscle weakness and atrophy. This disorder is common and is passed on genetically to children by their parents. You cannot “catch” Spinal Muscular Atrophy by being around someone who has it. It is caused by progressive deterioration of the anterior horn cells of the spinal cord.

Phosphate) as well as change in bone architectures. It is a common silent disease that affects both sexes normally as they are aging.
Patients with classic mitral valve prolapse have excess connective tissue that thickens the spongiosa and separates collagen bundles in the fibrosa. This weakens the leaflets and adjacent tissue, resulting in increased leaflet area and elongation of the chordae tendineae. Although mitral valve prolapse is a lifelong disorder, many people with this condition never have symptoms. When diagnosed, people may be surprised to learn that they have a heart condition. When signs and symptoms do occur, it's typically because of mitral regurgitation.
DEM 301 Understand the process and experience of dementia 1 Understand the neurology of dementia 1.1 Describe a range of causes of dementia syndrome Alzheimer’s - Alzheimer’s is caused be ‘plaques ‘ and ‘tangles’ developing within the brain which causes the brain cells to die, over time the disease progresses damaging other parts of the brain. To begin with individuals will experience memory loss and problems with word finding, as it progresses individuals may find it hard to communicate, forgetting names and places, become confused and unable to carry out every day living tasks. Vascular Dementia - Vascular dementia is caused by a lack of blood supply to the brain, starving the brain of oxygen which causes brain cells to die, this can be caused by a stroke or mini strokes over a period of time. Individuals with vascular dementia may have paralysis or weakness as in a stroke, have difficulty communicating and become confused, suffer from depression, incontinence problems and memory loss. Mixed Dementia – Mixed dementia is when an individual has Alzheimer’s and vascular dementia, the individual may have symptoms relating to either Alzheimer’s or vascular dementia or a mixture of both.
There is no known cure for multiple sclerosis at this time. However, there are therapies that may slow the disease. The goal of treatment is to control symptoms and help you maintain a normal quality of life (“What is Multiple Sclerosis”). There are medications used to slow the progression of multiple sclerosis, and are taken on a long-term basis. The outcome varies, and is hard to predict.
