The cause of the brain cells dying and the deterioration of the connectors is not fully known. Vascular dementia is a form of dementia caused by damage to the brain through deprivation of oxygenated blood. Causes are preventable and include high blood pressure, heart problems, diabetes and high cholesterol. Rarer forms of dementia are Creutzfeldt-Jakob disease (CJD) and Biswanger’s disease. 1.2 Types of memory impairment Whilst long term memory loss is experienced, short term memory loss can cause more problems, although it is not the same in every case.
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.
Loss of SMN1 gene results in loss of function of specific proteins required for RNA processing. This abnormal RNA processing seems to have a toxic effect on the lower motor neurons and results in their progressive degeneration in the spinal cord and also in the brainstem motor nuclei of cranial nerves 5,7,9 and 12. Werdnig-Hoffman paralysis or SMA type I can also be related to / can also cause congenital heart defects in severe cases. Studies have shown that patients with a single SMN2 copy, have higher incidence of getting an atrial septal defect (ASD) or ventricular septal defect (VSD). Patients with only 2 copies of SMN2, have higher incidence of getting minor cardiac anomalies including patent foramen ovale (PFO) and patent ductus arteriosus (PDA).
Huntington also creates inability to enjoy life and lack of energy. Sometime delusions and hallucination, paranoia, and bad behavior occurs. After age 50 some people may suffer depression rather than anger or irritability. These symptoms affects many parts of the human body that why we need a medical answer to prevent and stop this disease. People in families with high percentages of Huntington don’t have a promising future even the children are at risk.
Researchers believe that Alzheimer's disease may be the result of one or all of the following: D. a slow virus or a biochemical imbalance in the brain E. an auto immune reaction (the body attacks itself) 3. Symptoms of Alzheimer's disease A. Usually a person with Alzheimer's disease becomes gradually more forgetful, and his or her personality and ability to think are also affected. It is important to remember that each person is affected differently by the disease so what happens in one person may not happen in another. B.
Other less common causes of dementia may include depression, head injuries, alcohol misuse, brain tumours, infections of the brain such as HIV, Strokes, or lack of Vitamin B in the diet. These causes of dementia can be treatable or non progressive or in some cases reversible such as vitamin deficiencies or thyroid problems. Rarer causes of dementia include Huntington’s disease, or progressive supranuclear palsy. 1.2 The different types of memory impairments commonly experienced by individuals with dementia include thought impairment such as storing and retrieving memory problems, calculation, spelling, planning and organising. Many people can also have difficulty with day to day tasks.
Alzheimer’s disease- Alzheimer’s disease is caused by the build-up of proteins in the brain which form into “plagues and tangles”, these in turn will cause a loss of connection between nerve cells and cause cell death and loss of brain tissue. Early symptoms of Alzheimer’s can be lapses in memory, problems with language (forgetting words or their meanings) and poor visuospatial skill’s (gaging distance, ability to see in 3D). People can also suffer from depression or anxiety, they could become withdrawn and lose interest in daily activities or hobbies or have poor initiation. As the disease progresses sufferers can develop more pronounced memory problems and lose a sense of time and place, they may forget where they are or have difficulties recognising their own family. Vascular dementia- Vascular dementia is caused by the flow of blood and oxygen to the brain being interrupted causing the death of brains cells, this is called an infarct.
They can worsen the symptoms, but they are not the cause of the disease. We don’t know what makes a person get the disease. About 15% - 20% of people, the disease runs in the family. This true of people who develops the disease at a young age. Crohn’s disease is a chronic disorder that causes inflammation of the digestive or gastrointestinal (G.I.)
This can be caused by a stroke or hardening or thickening of the artery walls which impedes the flow of blood. The vascular system can also be damaged by heart disease, high blood pressure, high cholesterol and diabetes. The brain cells eventually die and this leads to the onset of vascular dementia. If these conditions are treated early enough the onset of dementia may be delayed or even halted. There are different types of vascular dementia and they are dependent on which part of the brain has been damaged and how the damage was caused, as different parts of the brain control different functions of the mind and body.
Doctors and specialists have noted that many of these behaviors are triggered by other factors that the person with Alzheimer's disease no longer knows how to recognize or control. These can include physical symptoms of other conditions including minor infections of the ears, sinuses or urinary tract, normal bodily signals that are no longer recognized including a full bladder, thirst or uncomfortable temperature, or side effects of medications. Alleviating these feelings and making use of stress management techniques can often bring increased calm to the
